You would have to test the distance of both the points to do that. Using a local or global variable to compare on every tick. Something like this to test out. You might have to play with the distance. cause it depends on where the origin point is set for this it was to 64x64 sprites with the origin set in the middle.

You could check if x1 is the same as x2 and y1 is the same as y2,
but if these are moving objects it will allmost certainly never happen.

You could check if the distance between those points is less than a certain distance and have that call the actions ..

@PhoenixNightly

To get the distance between two points in pixels you can just use the expression - distance(x1,y1,x2,y2)

Thx LittleStain
Raise the comparison up half the width of the sprite should work.
