The rules are simple. By the end of a given month, make and post a link to a completed, playable video game. The only restriction is that it must be YOUR game...not a game you've copied from somewhere. Doing so results in fame, fortune, and your name posted here as completing the challenge. Failure to do so will result in no points, eternal dishonor, and may god have mercy on your soul. A theme will be suggested for each month, but it's strictly optional.

Month 1: August!
Theme: Retro space games!

Month 2: September!
Theme: Fun with tiles!

Completed:
Spectral Phoenix - Missiles (http://www.megaupload.com/?d=LJ63MNUU)
DragonSamurai77 - Space Invaders (http://www.filedropper.com/spaceinvaders)

Competing:

Feel free to post discussion, tips, questions, and whatever else you find fitting. If you find yourself in need of a place to upload your game to, hit me up, I have more web server space than I can ever use.

This is a good site I just found that gives advice on making a Space Invaders style game. (http://scalablegamedesign.cs.colorado.edu/wiki/Space_Invaders_Tutorial_3)

I strongly advice checking out the XNA package from microsoft for a few reasons.

1. It's extremely well documented. Great tutorials. Step by step, with explanation. This is all kinds of awesome, as documentation for some things assumes a lot of prior knowledge.
2. It's entirely free on PC. This is...nice.
3. You can port them to xbox. This costs a little bit, but it's seriously still quite inexpensive. There's really no other comparable way to develop for consoles.
4. It's in C#. This is an actual language used in the real world. Damned handy skill to have.

VB is another solid option for getting started.

Lots of good languages out there. Any of the easy ones is great to get you started, once you've absorbed one, the next is always easier.

Maxios
2011-07-18, 08:56 PM
What is the easiest programming language to start out with?

Tyndmyr
2011-07-18, 09:04 PM
Well, it depends what you're trying to do, really. VB is probably the simplest for making a quicky windows app, for instance. Standard grey boxes, things like that. A solid choice if you're making say, a drug wars style game that's low on graphics, but you want it to still be a windows app instead of command line or w/e.

C# is probably among the easiest for 2d graphics thanks entirely to XNA.

Certain specialized apps like RPGmaker will be easier...but only for specific styles of game. If your game concept fits into such a slot....by all means, take advantage of it. It just doesn't work for all game concepts.

Honestly, the key is mostly picking a good, simple concept to start out with. Lots of retro games have such a thing...possibly with additional options built around it. So, cloning a retro game is a great starting place. Typically low graphics required, relatively simple gameplay.

What's a good free (or under $10) program that allows you to create a very simple RPG?

Tyndmyr
2011-07-18, 10:24 PM
Well, RPGMaker has a free trial.

Or, you can use a more generalized language...if it's a very simple RPG, you can aim for that with anything. I've personally built a reasonably complex RPG in visual basic(flipped into shooter mode in combat). I know there's a starter kit for making an RPG in XNA as well. You should be able to strip graphics off either the XNA site or the Torque site.

Links:

Garage Games (http://www.garagegames.com/): Makers of torque 3d engine, a few other fun things. Very powerful, documentation is sometimes lacking.

Milkshape (http://chumbalum.swissquake.ch/): My personal favorite 3d modeling app. Not as powerful as 3d studio or blender, but remarkably easy to use. Also cheap($25, IIRC). Note that you only need something like this if doing 3d.

Paint.Net (http://paint.net/): Free graphics app. It ain't photoshop but it beats the hell out of the standard Paint. And it's free.

RPGMaker (http://www.rpgmakerweb.com/): Specialized RPG app. Easy top-down RPG building, not particularly useful for other things.

Visual Studio Express (http://www.microsoft.com/visualstudio/en-us/products/2010-editions/express): Free compilers for C#, C, Visual Basic, etc. Microsoft is pretty good about such things. If you prefer linux, hit up Mono instead.

XNA (http://msdn.microsoft.com/en-us/aa937791.aspx): The XNA library for C#. Grab it and the microsoft C# compiler and you're in business. I recommend the app hub for starters.

I was going to get back to learning ActionScript for Flash games anyway, so I'll join in. I'll try to do a blog-like walkthrough of what I'm doing so it's easier to follow (either here or linked to elsewhere; need to think about what's best). I might go through a few steps before getting to the retro space game, such as setup/Hello World, a dead simple game prototype, Pong, Breakout and then Space Invaders.

What programming language have you decided to use in the end?:smallsmile:

Maxios
2011-07-19, 05:32 PM
Not a language, per say. I downloaded a demo of this simple-game creation software called AgentSheets. I linked to a tutorial on making a Space Invaders game using AgentSheets earlier, though at the time, I thought it was for a totally different software. The problem is, it's not as easy as it seems.
Once I fix all the bugs, I know how to upload it onto the internet so you guys can play it.

Tyndmyr
2011-07-19, 05:32 PM

Certainly. I could use some help keeping track of everyone.

Basically, I figure as long as they made a game(it need not be an original concept...hell, you can follow a guide), and it can be played, it's a win.

More good news and bad news!

Good news: The game is done, and it is awesome!
Bad news: I don't know how to upload the game anywhere. There is an official site for games made with AgentSheets, but apparently it's for some college or high school in Colorado :smallsigh:

Official Game Summary:
The Aliens have invaded the spaceship you're in! As Space Marine #43.64, it is your duty to collect the batteries to power the Death Ray that will wipe out the Aliens! However, the Aliens have spilled acid on the floor, making it impossible to backtrack! After you end up trapped- or dead via aliens-count the remaining batteries. If there is 30 or less batteries left, you have gotten enough batteries to power the Death Ray and you win. If not, you can always replay the game.

I'd recommend making this more of a personal challenge than a contest, as everyone will be at different skill levels. Absolute beginners shouldn't be concerned if more experienced developers want to join in.

I'd also advise putting too heavy an emphasis on creativity or innovation for beginners, because it's a challenge enough to learn the basics of programming. That's one of the reasons why making a retro game clone is recommended - the game idea is already there for you, go ahead and learn how to make it.

I'm thinking just a simple pass/fail every month, perhaps with kudos for people who have made something really awesome, or shown solid improvement. Nothing necessarily all that formal, just a way of recognizing what people are doing, and giving each other a bit of help.

Retro space games, I was thinking things like astroids, space invaders, missile defense...but really, almost any game could have a space theme. And the theme is optional anyway. I'm not even quite sure what I'm doing myself yet.

For those in the Baltimore/DC area...I have a small library of coding books myself, a lot of which are game coding. Always fun getting people started and what not.

A jar can be run locally, so all you need is a file server. I can arrange hosting for that. As in, I've got a server with ludicrous bandwidth and unused capacity.

Is it possible to be a judge as well?

spectralphoenix
2011-07-21, 12:45 AM
As I understand it, this is an unjudged challenge rather than an "Iron Programmer." If this is to be a competition, we're going to need a much clearer theme and ruleset. Further, I would recommend that the judges be people with a good understanding of programming themselves.

On that note, I'd like to give this a shot as well. I'm thinking of making a Missile Command game in Microsoft Silverlight.

SamBurke
2011-07-21, 12:46 AM
True, but still.

If we're talking about code, I'm not an expert. At all.

However, judging/rating/ranking/critiquing games/art/play etc, I can do.

Tyndmyr
2011-07-21, 08:39 AM
Yeah, I'm thinking more personal challenge/learning exercises than a competition. It might be a fun idea later, but I feel like we have a lot of people here interested in learning, and working on that is probably best for now.

That said, hopefully people will toss up their games for others to play, critique, etc. I'm thinking about doing a missile command knockoff...or a top-down flying game. Or a moon lander game. Still indecisive. It'll definitely be 2d in C#, though. I've already got the parallax working for layered backgrounds.

Another link to add:

turbosquid (http://www.turbosquid.com/) which is pretty awesome resource for textures and 3d models, some of them cost money but there is tons of free stuff which can be used in freeware/shareware applications without a problem.

And yes paint.net is pretty good especially if you install all those nice plugins.

I personally would stay away from the free visual studio version since it lacks some key features you really want to have to speed up development time.
As far as I remember (it is some time now) you couldnīt even auto generate getters and setters and there was no auto completion or refactoring.
The normal version is great however.

Instead I would use sharp develop (http://sharpdevelop.net/opensource/sd/) which is a complete ide and not just half of it

For java programming either netbeans (http://netbeans.org/) or eclipse (http://www.eclipse.org/) work both just fine and have all the features you want.

Basically, the main point of danmaku games is that the enemies don't simply shoot at you; they carpet the entire screen with layers of bullets. To program such a game, you need to think of beautiful and deadly patterns for them to follow.

Depends on what kind of file it is. If it's an executable, just put it on a free web hosting service. If it's a .swf or the like, it might be easier to just embed it in a site and talk to one of the people who offered to host games in the beginning of the thread. If it uses third party software to run, make sure you link to the site where that comes from.

The healthbar goes down incredibly slowly because of the boss's massive health. As for the controls, I suppose I could add WASD as options, but then I'm not sure where to put the shooting and slowdown.

Well here is my submission of a design document for
"Perseides! Asteroid Shower!"


Background:
You are an astraunaut on a resupply flight to the ISS during an asteroid shower. The ISS has boosted its orbit high up to avoid a particularly bad perseides shower. Unfortunatly, your computer guidence system died to an unexpected solar flare. You will have to survive successive intense 30s to 90s rounds of asteroid showers before arriving at the ISS.

Gameplay:
A spaceship, controlled WSAD or UP-DN-L-R has to dodge successive waves of falling asteroids. Initially, they come from the top of the sceen, but gradually asteroids will start having oblique trajectories through the screen, too.
As an added difficulty, the first crash will diminish manoeuvrability of the ship, the second will cause the ship to gain a slight inertia in control, the third is fatal.
Damage is indicated to the player, either on the ship, or by red warning bars appearing around the playfield.
Rounds last 30s to 90s.
Optional: A computer indicator up top of screen indicating arrival vector of next asteroids.

Necessary graphic assets:

Spaceship with (up-down-left-right-static) movement poses
Optional: Damage indicator on ship asset // Damage indicator on screen
Variety of asteroids
Backgrouds (optional) - Possibilities, a view of earth scrolling down to give impression of velocity


Necessary sound assets:

Music: BMG Loop
Computer voices (Danger!Danger!, Incoming asteroid shower!, Warning!Damage!)
Damage sounds (crash!)


Extras:

Splash screen with New Game A (Normal) / New Game B (Hard) button
Pause button
High scores
Game over screen


Iteration steps:

Ship on background, movement U-D-L-R with animation
Asteroids following vectors through screen with adjustable velocity
Collision detection - damage
Damage effects modelling
Background scrolling
Rounds
Sounds, BMG
Game over, Splash screen, New Game
Polish + High scores

I'm going to be doing this in flash, as a way to expand my repertoire. I already did a Tetris following Emmanuele Feronato (http://www.emanueleferonato.com/)'s blog and book to learn about flash.

I hope I'll be able to put time aside to do this little project.

To be honest, it would probably be cool if we did this in a format similar to tigsource's Assemblee competition (where the first phase has a group of artists slave away to produce a set of graphical resources, and the second has a group of devs slave away to turn those resources into a game).

Otherwise, I'm currently ruminating on a design. I might have a bit of RealityTM to (mis)handle soon, but I'm still hoping to have something hacked together for the end of the month.

Update 1 of Perseids!

- Background image present (thank you NASA)
- Rudimentary ship present
- Up - Down - Left - Right movement of ship
- Framework in place for next steps

So basically half of point a) on my list.

Well, I've successfully mishandled that bit of reality, but I'm no closer to actually getting this done. I'm pretty sure I do know what I want to do, however, which may be an improvement.

Art-wise, I'm hoping to scrape by as far as possible on primitives, at least this time around.

Gameplay-wise, I'm looking at an arena-esque shooter, with some similarities to Asteroids.

Fireballs on impact. When it hits, it creates shockwaves. Boomerangs. Multi-shot. Flaming shot. Chain shot. Shockwave shot. Lots of great things here, man.

I'm about to start my second year of college, for the major of game design, and I've been told that it's very important to have some good examples of stuff you've made, and this sounds absolutely perfect for padding out my portfolio . . . besides, I really need the practice since I did almost nothing over the summer.

Since there's only 10 days left, maybe I'll just work on remembering how to get a movable ship on the screen . . .

The Left Hook (ship)

Not entirely up to snuff, ruler-wise, but might be usable to you anyway. :smallsmile:

(Dunno if i should also make bullet/laser types. Those are usually easy enough for yourself to make.)

I've managed to implement a ship flying around an empty screen -- it runs to about 200 lines of code, some of which is currently superfluous (for example, the ship has a collide method, even though there's nothing for it to collide with).

At some point today, I'm hoping to implement something for the player to do, figure out some sort of UI and game state management, and introduce some actual obstacles.

Since this competition started midway through July, should we think about deciding on a theme for September?

Heh, I also whipped up some filler art for folks to use...I'm afraid yours is much better, as my graphics skills are weak at best, but hey, coder art is better than no art.

Sub out the Blue in the link for Green, Yellow, Red, Maroon, or Grey as desired.

Hmm... good question. I'm pretty sure most people interpreted "space game" to mean a real-time game with pixel-based movement, so something tile-based or turn-based would make a good contrast.

However, I'm not sure what to suggest that would make that more specific.

Tyndmyr
2011-08-22, 08:42 AM
Tile-based or turn-based could be a theme, sure.

As always, there's a *lot* of ways to do such a thing.

I do think I have some tile graphics laying around I could make into useful things, though.

Today's update:

As far as August's entry is concerned, I haven't really made any more progress beyond cramming everything into Fossil. I do have the start of a game state manager done, however, and I'm thinking through how best to implement the next stage (things to shoot and things to shoot at).

For September, I believe I have a concept, but I don't really want to start on it until everyone's agreed on the theme.

Asteroids are present, collisions are handled.

I need to do the rounds, damage and all that. Not had much time since I did a surprise trip to Prague over the week-end.

Tile/Turn-based would be a nice game, it can cover things from chess to wesnoth to card games... But always start with something small.

Well, the main objective is to release something playable -- it doesn't have to be amazing, and IMHO, there's nothing wrong with a demo or a prototype as long as a decent amount of work went into it.

While not as abundant as you might expect from the internet, free tilesets do exist. You can also make an ASCII roguelike, which falls under "fun with tiles" theme practically by definition.

Alright, I put together a Missile Command-style game for Microsoft Silverlight, available here (http://www.megaupload.com/?d=B8U9YSFZ). A, S, and D select from the three guns (left, center, and right, respectively,) Left click fires a missile, and R resets the board. The goal is to get as many kills as possible before all of your cities are destroyed. Remember to lead your targets by a fair bit, friendly and enemy missiles travel at the same speed.

To run, simply unzip the folder and open MissilesTestPage.html IE should already have the Silverlight plugin installed, Firefox may need to get it from Microsoft before it can be played.

I may post the source code for this later (I was teaching myself Silverlight as I went along, right now it needs some serious refactoring before it's fit for polite company.)

Well, Real Life (coupled with a stupid forum discussion where I managed to act like an idiot) happened again, so I haven't made any more progress with either of my projects.

And while it's fun seeing things come together and figuring out how to make them work, I can't really say I'm a fan of arcadey space games, which might also have made a difference. I'm pretty sure I've put more thought into the game I'm planning to make for the end of September than into this one.

As far as making everything web-playable... yeah, I'm sorry, but I don't think I can really manage that, certainly not for the August project.

Right. I don't want to place many restrictions on technology. I mean, web-tech only really limits a lot of game types.

Ima give an extra day for uploading, so things posted on Wednesday count too. With month long projects, it can take a minute to get the install working and online if your hosting/buddy's hosting hates you or something.

I'm going to try and finish it for Wednesday, but Real-Life is interfering quite a lot. Helping my gf find a new apartment in Paris before the end of this week is a challenge.

I've got the game basics, but need to add collision counts (damage), levels, sound and better graphics. I will finish the game, hopefully before Wednesday. I'll also post the full source code in Flash for anyone to use / hack and learn from when I'm done.

Tile-based sounds like a good September one. Anyone else doing some flash?

I've been hacking around in Flash/AS3, but I'm mostly a newb at ActionScript and have been spinning my wheels a bit. I've been trying to work from basics but in retrospect it hasn't been the best strategy and I've let time slip away from me. I'll see what I can hack together in flixel quickly and see if I can a game together by the end of the week (admittedly a few days late. Hopefully I can get a skeleton done within the time limit).

And yeah, I've been working from basics as well, although in Ruby (http://www.ruby-lang.org/en/)/Gosu (http://libgosu.org/).

It hasn't been too hard, although I suspect that when I start on the next stage (enemies), I'll run into some kind of nightmare. Handling spawning has already provided at least eight different kinds of entertainment over the last week or so.

There's actually a competition elsewhere called "game in a day". It's basically a 24 coding marathon. Definitely possible, though a bit on the rough side.

I think my school participates in something like that. You can get a small team together and you basically can't leave the room until you have a game.

As for my game - well, because I really needed a simple way to get back into practice, I just made a simple clone game. There's a ship, you move it around the screen, and asteroids fall from the sky. Now I've got the ship moving, and the asteroids fall randomly like I wanted, and the ship shoots bullets alright, and I've borrowed one of Domochevsky's shield images (thanks for those!). I even learned to make a bar in the corner that will run down if you use the shield, collapses the shield if it reaches 0, and starts regenerating properly after you let it go.

Now, it might be playable if I could get the collision detection to work properly . . . :smallannoyed:

lesser_minion
2011-08-29, 05:01 PM
So, remember that nightmare I predicted?

Just implemented a turret enemy. It does nothing but fire unled shots at you until you or it dies.

Unfortunately, collision detection is monumentally broken, and currently it seems like you can completely own the game just by flying in circles and shooting. If you stop shooting, you die in short order. Bullets are too small and too fast to see, and I'm not sure the enemy bullets are being drawn at all.

So... definitely needs improvement. And more refactoring. If nothing else, I'm pretty sure I know what I should be doing differently, and why. So this exercise won't be a total loss either way.

I was searching for some background music and found a guy who allows his songs to be used if you credit his website: http://danosongs.com/ .

I'll be using Matiere Noire Vibrante (http://www.danosongs.com/music/danosongs.com-matiere-noire-vibrante.mp3) [direct MP3 link] as a background music.

Any programming you do is never a loss as long as you do a postmortem after a project and reflect on what went wrong and what went right. And also take the time to copy-paste the best pieces into a code repository (sorted by language / subject) so that you can keep them as reference for a next project. Thus building up your portfolio of snippets.

Also Here's a quick guide to adding sound in flash:
Sound handling in Flash
//Note: This assumes you place the MP3s in the folder next to the flash flv. I'm not embedding them in the file so they could be exchanged.

//Imports (at top)
import flash.media.Sound;
import flash.media.SoundChannel;

//VARIABLES - GLOBALS
private var sndChannel:SoundChannel;
//Background music
private var music:Sound;
private var musicPos:Number;
//Sound Effects
private var SndEffect1:Sound;


//LoadSound Function
public function LoadSound():void
{
music = new Sound();
music.load(new URLRequest("danosongs.com-matiere-noire-vibrante.mp3"));
music.addEventListener(Event.COMPLETE, SoundLoaded);

SndEffect1 = new Sound();
SndEffect1.load(new URLRequest("schlup.mp3"));
}

//Start playing in a loop the main BMG as soon as it is loaded for 100x
public function SoundLoaded(e:Event):void
{
sndChannel = new SoundChannel();
sndChannel = music.play(0,100);
}

// Code Snippet to Pause BMG music and Resume it after a pause at the same place
if (paused == true)
{
paused = false;
sndChannel = music.play(musicPos, 100); //start playing at position
}
else
{
paused = true;
musicPos = sndChannel.position; //Record sound position
sndChannel.stop(); //Stop all sounds in channels - clears ongoing sfx
}

//Code Snippet to Play the sound effect immediatly
SndEffect1.play();

For my September game (which I know I'll deliver mid-October since I always slip by deadlines), I've started the following design document:

Tower of Ruin - Tactics - Design document

Using the system: Warrior, Rogue & Mage

Background
You are an unnamed protagonist delving into the tower of Ruin, where the terrible sorcerer Ranalth lives. He threatens to destroy the world, you have to defeat him before he can put his plan to execution.

Gameplay:
Using the freely available (and slightly simplified / adapted) rules of WR&M, you navigate your way through a top down tactics game, room by room. Each room can have multiple exits and you need to visit them until you find the stairs to lead you up. At the end of the dungeon you will fight Ranalth. Combat is on a turn by turn basis, where you have a certain number of action points, moving costs 1 point, attacking and magic end your turn. A basic inventory is available.

When not in combat, the player can move freely on the grid.

Screen has: A game map area, a combat turn indicator on the side, a player recap with player stats and health at the bottom of the screen. Actions are selected from a menu on the vertical sidebar.

Graphic assets needed:
Land graphic times for the dungeon floor
Character assets
Item assets on the ground

Sounds needed:
Dungeon music
Magic sound effects

Extras:
NPCs with dialog
Helpers you can recruit in dungeon

Iteration steps:

Basic state machine design for the game
1 room, with character moving
2 linked rooms, map scrolling
Combat system, turn by turn, turn list on side of screen
combat system implementation (attack)
combat system menu
Character creation
Handling level ups
Magic system implementation
Inventory system
World definition from files
Enemies defined from files
Saving progress
New game screen
Music, sound effects and polish


It is quite ambitious, I probably won't be able to deliver a full game like Perseids for this one. But hey, aim for the moon, you might hit the sky.

I've also got an idea for an other game, but I'm keeping it under wraps for a new competition which would fit. The name would be "You are the boss"... guess the game :smallbiggrin:

Really, can be anything you want. Hell, it could be a game about installing ceiling tiles, if you wished.

Remember, the theme is optional. So, if a game doesn't get finished in one month, you still get credit for the following month if you submit it later. Finished games are finished games!

Managed to do a little progress on Tower of Ruin. I prepared a generic State engine in Flash so that I can now control execution flow in an easier way. As a test, I have now a logo screen that gets shown before the transition to a main menu.

Next part is to prepare the overview map and start the movement of a player and scrolling. Also, I need to verify my way of passing Key and Mouse events to the state machine is done in a way to support me without issues. In effect, I'm sending a lot of time on a framework that I expect to be re-using for later games.

Update: 8 Sept 04:53
I'm making progress in leaps and bounds, now have a complete mouse and keyboard support all through the state engine. I have also started on the map rendering, supporting Square, Skewed and Isometric projection on the same simple codebase. (I'll also add Hex rendering as an exercise, even if I have to tweak another ruleset for that.)

The "Hero" can move around the map, checking for inaccessible squares before movement. There is a mouse overlay to indicate which floor tile is under the mouse (not shown in screenshots).

Please ignore the horrible programmer art in there (Mostly the Tower of Ruin menu screen). The logo squirrel was made for me by my talented girlfriend and the character art comes from http://www.squidi.net/three/entry.php?id=121 where I took the idea for a skewed world representation. I'm not yet settled on which one I'll use (or if I'll allow players to switch in battle?). Each of the scrolls on the main page goes to a different representation (square, skewed, iso) of the world.

Progress image spoilered for size
http://img827.imageshack.us/img827/9088/towerofruin.png

Next part is multi-room support and map scrolling, plus other user interfaces like the status bar and the combat tracker. Mouse click support to come.

With 2D art (or 3D with an orthographic lens) definitely go 45. 3D with a perspective lens can go either way.

Tower of Ruin is advancing very slowly. I implemented the base rules (characteristics, skills, weapons, armour, attacks, dice rolls, damage, movement and hitpoints) for the game system. I also have room switching where I can have multiple rooms with exits to a new room and rooms can be larger than the screen because I've got very basic scrolling capability.

Next step is to build the:
Combat system, turn by turn list on side of screen
combat system implementation (attack)
combat system menu

So that I have a real mini-demo to show. My guess is that will be it for the month. I'm focusing on Top-Down view while I get the rest of ToR sorted out and I'll get back to other rendering schemes later.

Formulas for each type of map, if anyone needs them.

for (var i:int = 0; i < mapHeight; ++i) { //y coord
for (var j:int = 0; j < mapWidth; ++j) { //x coord

Square Map (Top Down view)
Map: Tiles disposed by X = j * Width, Y = i * Height
Mouse coords to tile: Xtile = Math.round((Game.mouse_pos.x - TILE_WIDTH / 2) / TILE_WIDTH)
YTile = Math.round((Game.mouse_pos.y - TILE_HEIGHT / 2) / TILE_HEIGHT)

Iso Map
Initial displacement is to put the map far away from the edge of the screen
InitialDisplacement = (mapHeight * TILE_WIDTH / 2);
Map: Tiles disposed by
X = (InitialDisplacement + ((TILE_WIDTH/2) * (j-i))
Y = (TILE_HEIGHT/2) * (j+i)
Mouse coords to tile:
yTile =Math.round((2*Game.mouse_pos.y-(Game.mouse_pos.x - InitialDisplacement))/ TILE_WIDTH);
xTile = Math.round((2*(Game.mouse_pos.x - InitialDisplacement))/TILE_WIDTH + yTile )-1;

Skewed Map
private const SKEW_OFFSET:int = 13;
Map Tiles disposed by
X = ((TILE_WIDTH - SKEW_OFFSET )*j) + i * (SKEW_OFFSET + 3)
Y = TILE_HEIGHT*i
Mouse coords to tile:
yTile = Math.round((Game.mouse_pos.y - TILE_HEIGHT / 2) / TILE_HEIGHT);
xTile = Math.round(((Game.mouse_pos.x - TILE_WIDTH / 2) - yTile * (SKEW_OFFSET + 3)) / (TILE_WIDTH -SKEW_OFFSET));
