How do I Make Platforms Vanish After Walking on Them

So I have been struggling with this for a while now. I want to make it so that my player Sprite can move across a solid Sprite using the platformer movement and after the player is no longer touching the platform, the platform should disappear - I can't seem to find the right event to make this happen.

Give it a variable. It's 0, in collition with player, set it to 1, you could start a timer to get rid of it.. or, when player distance is further than 30 (eg) and the variable is 1, destroy the platform.

A Boolean would also work

Add the an instance variable (boolean) to the platform named "trigger"

Add the Fade behavior on your platform and name it FadeOut.

--With these properties:

---Active on start: Yes

---Fade in Time : 0

---Wait Time: 0

---Fade out Time : 1

---Destroy after Fade out : Yes

Add these events:

Comment: For the trigger

+Player - On collision with Platform:

->Platform - set boolean (trigger) to true.

Comment: Fade Out (Destroy Fade Effect)

+Platform is boolean (trigger)

++Player is not overlapping Platform

-->Platform - FadeOut : Fade Out start

Comment: Anti-Solid Bug

+Platform on destroyed

++Player is overlapping Platform

-->Player - Set Y to (Self.Y + 1)

I hope that works out for your game.

This code works great thanks. One more thing, I have several platforms in my game, will I need to do this for every single one of them?
