This is a quick example map that I made to show a friend how to stop players without clip brushes. The prefab includes the vscript, the hammer map file, and the compiled version of the map with the vscript packed inside.
The first example requires no vscripts by simply placing the player in the ground by 1-2 units. While this method is simple to use, it isn't recommended as the ammount of time stuck in the ground can vary.
The second example uses a vscript that sets the players speed to 0 when it finishes teleporting them. They can instantly restart their run and won't be teleported backwards. Use this one.
