question

The documentation is more confusing than it actually is and I rarely ever understand it until it''s put into an example so could someone please make a program that loads a scene (a pathway) then go into paint and fill in the different sections of the scene with either one of two different colours, i''m using white and brightgreen, if the area is white the character can walk around, if green the character can''t. Then save the picture as collision.bmp, now make a 50*50 square and load it in as a .bmp that you can move around the scene. now what happens is the program has to check the area of the 50*50 square bmp on collision .bmp (which doesn''t get blitted to anything i think) and see if there''s a green pixel and if there is return the squares position to it''s old value. it sounds a little confusing but if you modify cone''s 2nd tutorial (the moving .bmp one) then it''s not hard to do EXCEPT FOR GETTING THE COLOURS!!!!!!
