game

Hello CodeProject Community,

I am developing a 2D game in Java, and I would like to be able to use level maps.

I am open to any way of doing it, completely in Java without any extra software.

I either want to use arrays or text files, and then numbers to mark the different blocks/textures.

If possible could you also please show me how to make a certain number/character in a level map load a certain image? Also if possible I would like to know how I could make the image draw on the correct part of the screen.

Thanks!
