Is it at all possible to check if the whole of Object_A is overlapping a specific point of Object_B? I'd like this done using a single object as there will be more than one of Object_B.
Give object B a second animation which is maybe a 2x2 pixel. At the top of your event code, have it switch to that animation. At the bottom, have it switch back to its normal animation. Then, for the whole code section you want, it will only have the collision map of a 2x2 pixel- use hotspots to offset it properly
Thanks Pixelthief, I don't know why I never thought of that because I've used it in the passed for other occasions. I can't seem to get it to work however. I have the following events:
Always - set animation of Object B to collision map
If Object A is overlapping Object B - Add to alpha coef of Object B (make it disappear)
If Object A is NOT overlapping Object B - Subtract from alpha coef of Object B (make it appear)
Always - set animation of Object B to visual one
