I am using a script to reset the level when the player interacts with a gameobject. The player is an empty gameobject, a capsule, and a camera (with children). I added a mesh collider to the empty gameobject and set it as trigger, but nothing happened. I tried the same thing on the capsule. This worked, but the player keeps falling through the floor. How can I fix this?
You’re either falling through the floor because the player is placed below the floor in the editor (just try moving the player upwards a little bit) or because you tried to make the floor into the level loading trigger.
GameObjects being used as triggers are ignored by physics calculations, so if you make the floor a trigger you will fall through it.
As for your empty GameObject - emptys have no mesh, so if you put a mesh collider on it you’re giving it a collider that can’t collide, so to fix that problem switch the mesh collider to either a box or sphere.
