I want to make a floor that when a character interacts with it, the character will jump and not fall through. and also, does a floor just need a component attached, just tryin to make this question longer so it dosen’t get rejected…
Just make a 3D Plane and add a Box Collider component. Add a script with an OnCollisionEnter() function to tell your character to jump.
see Unity - Scripting API: Collider.OnCollisionEnter(Collision)
