You can do this quite easily with the spriteCollision function. All you need to do is put a 1x1 pixel image at your mouse position
dbMouseX() dbMouseY()

then check to see if the mouse's sprite is touching the sprite you want to press

No, that won't work. Sprite collision checks the whole rectangular image, it does not take into account transparency.

There have been attempts to implement pixel-perfect collision and there was a vector collision as well. I've just made a search for the thread titles, haven't personally tested either of them. Try if one of these posted solutions work for you:
