Can I ask you a couple of questions about this engine?
1. How could I resize the viewing window and move it so that it is not in the top left hand corner?
2. I would like my game to run in 1024x768 resolution, what in this code would I have to alter?
3. Most importantly, I would like the program to be able to recognise what tile I have clicked on.....and possibly change the image used for the tile (to signify that it has been clicked). I have no idea how to do this......I have just come from programming a text only game!
