How do you make it so an element can jump through a platform?

Here is an example of what I am trying to do Add a ‘Jump through’ platform [GDevelop wiki], it allows your player to jump through a platform and then land on it.

Hi @cjio and welcome! Do you use a dynamic rigidbody? I’m not sure what’s the best way, but maybe you can disable the collision component of the player when the player is jumping. Then you need to enable it when the player is falling. If you don’t use a dynamic rigidbody you can also use a raycast.
