Isometric Game Design.

[CTucker1327]

I’ve been trying… and trying… and trying to find online information that will help me with creating an isometric game, but I’m the kind of person that needs to read over something that works to understand it… and it seems that that the devil himself is making sure that the amount of literature for isometric games is ridiculously scarce.

I’m willing to pay anywhere between $100->$200 for a good book on Java Isometric game development, at this point I really want to understand it and don’t care about the costs. I’m not even trying to make anything big, just an isometric tower defence, just so I can say that I did it.

This is still frustrating the hell out of me, and I can’t figure it out. I decided to just go ahead and do the math for the Y Axis, but even then I can’t get it to calculate the tile position correctly.

Attempts:

	public String getTile(int screenX, int screenY) {
		int worldX = (screenX / (GameTile.TILE_WIDTH / 2) + screenY / (GameTile.TILE_HEIGHT / 2) / 2);
		int worldY = (screenY / (GameTile.TILE_HEIGHT / 2) - (screenX / (GameTile.TILE_WIDTH / 2)) / 2);
		return "Tile X: " + worldX + " -- Tile Y: " + worldY;
	}

	public String getTile(int screenX, int screenY) {
	    int worldX = mapData[0].length - (int)(Gdx.graphics.getWidth() / screenX);
	    int worldY = mapData.length - (int)(Gdx.graphics.getHeight() / screenY);
	    
	    
	    if(worldX < 0) worldX = 0;
	    if(worldX > tiles[0].length)worldX = tiles[0].length-1;
	    if(worldY < 0) worldY = 0;
	    if(worldY > tiles.length)worldY = tiles.length-1; 
	    return "X: " + worldX + " Y: " + worldY;
//	    return tiles[worldX][worldY];
	}

	public GameTile getTile(int screenX, int screenY) {
	    int twh = GameTile.TILE_WIDTH / 2;
	    int thh = GameTile.TILE_HEIGHT / 2;
	    int worldX = (screenX / twh + screenY / thh) / 2;
	    int worldY = (screenY / thh - (screenX / twh)) / 2;
	    if(worldX >= (tiles[0].length - 1)) worldX = (tiles[0].length - 1);
	    if(worldX < 0) worldX = 0;
	    if(worldY >= (tiles.length - 1)) worldY = (tiles.length - 1);
	    if(worldY < 0) worldY = 0;
	    return tiles[worldY][worldX];
	}

and numerous more I can’t even remember.
