convert 2D tilemap to Isometric

Java 2D
#1

Hi,

I have a very simple 2D tile engine. I’d like to know if there’s a simple way to convert it to Isometric view. I was looking over the internet but I wasn’t able to get my code working. If someone has an example… it’d would help a lot.

Here is the code I currently have:


	private int[][] currentMap;
	
   	int mapWidth = this.currentMap[0].length;
	int mapHeight = this.currentMap.length;
	for (int i = 0; i < mapWidth; i++) {
		for (int j = 0; j < mapHeight; j++) {
			int frame = this.currentMap[j][i];
			g.drawImage(this.tiles.getSubimage(frame * 32, 0, 32, 32),
					i * 32, j * 32, null);
		}
	}

It doesn’t have scroll yet, it simply draw the tiles in my screen.

Then I transformed the tiles into iso by rotating then 45 degrees and reducing the height divided by 2, but I’m not sure how can I render them. Any help?

Thanks

Here’s a look at one approach from gamedev.net: http://www.gamedev.net/reference/articles/article744.asp

yes, thanks for the link. But I can’t read C code very well… it was a long time ago when I worked with it… I’m trying to create the same demo using Java version but it’s getting too hard. Has anyone converted this example to Java? Or has another similar one?
