Detect when a collision is happening

Onulator

Trying to make it so that the player isn't able to jump in the air, current idea is to see when the player is touching the ground, and allowing the player to jump when doing that. How exactly do I do this? (Collision is currently working, just need the code to be able to tell WHEN it's happening)

Your character must be a KinematicBody. A KinematicBody has a is_on_floor() function. The character must jump only when is_on_floor() !

How exactly do I label the platform as a floor?

FopenP

You don't need to specify the floors. Every StaticBody (with a CollisionShape, f.e. a Trimesh Static Body) can behave as a floor. In the move_and_slide(velocity, Vector3.UP) you must set an UP vector and the floor will be seen as the upper part of the static body.

If you want to exclude a StaticBody from being a floor, there are collision layers and collision masks. https://docs.godotengine.org/en/stable/tutorials/physics/physics_introduction.html#collision-layers-and-masks If you put a StaticBody in another collision layer, it won't collide anymore (like a ghost).

For 'labelling' nodes of any kind check out the documentation on Groups and Signals.

For checking if your node is colliding generally, you can use an if statement then is_colliding() note though, that these features are context sensitive so you should look up the documentation to understand them properly.
