I AM TRYING TO MAKE A GAME FOR THE NEW CO-OPERATION CONTEST,
BUT FOR SOME REASON WHEN I TRY TO ROTATE A OBJECT THE SPRITE WONT ROTATE.
THE OBJECT IT SELF WILL ROTATE BUT NOT THE SPRITE.
PLEASE SOME TELL ME HOW TO ROTATE THE SPRITE!

Do you have a draw event? If so you will need to draw the sprite with "rot" image_angle. draw_sprite_ext is what you will need. Set the colour to c_white which means no color blending is used. Hope I helped

i think slammin sam is right, use the draw_sprite_ext code in the draw event.
image_angle doenst always do the right thing
