Player standing on object

Hi, is there a way to determin for the platform behavior, if the player is standing on a specific object. I would like to change the color of some of my platforms, when the player is standing on it.

I'm looking for a behavior that enables me to do that:

IF "Player is standing on object x" THEN "mark object x as active"

Thanks in advance.

hopefully this helps...

I used a variable and set it to when the player collides with the platform it changes frames....

i just have on idea to set it back to the original color for when it isnt colliding...

Thanks for your help. I tried something like that and had the exact same issue with switching back to the original color. I think I will have to calculate the difference between the player's outer bounds and the platform edges.

You could use overlapping at offset for this.

Thanks, this should do it! I didn't even notice this condition before.
