You have to check if they are overlapping.

If player overlapping Platform

-if animation frame = 1

-If DmgCD is false

--->do the dmg

If Platform.DmgCD is false

-> Wait 1s*

-> Set DmgCD to True

The DmgCD is a boolean instanced variable that you can determine how often the player can get hurt by that platform instance. So each platform have a different cooldown, meaning you still can suffer dmg from another platform.

*you can use a Wait or you can set a Timer. If you use Timer you don't need to use the variable DmgCD. You just need to check if the Timer isrunning or not.
