Is it possible to create an invisible barrier in Ursina Engine?

Question

Does Ursina allow for one to create an invisible barrier to prevent the player from falling off the map, if so, how could I do that, if not should I just add walls to prevent that from happening?

Answer 1

Yes, it is possible. You can create an entity and make it visible = False or just make it transparent (less optimized) color = color.rgba(0,0,0,0)

Here is an example:

barrier = Entity(model='cube', collider='box', visible=False)
