I have been using ursina for a little bit now, and this isn’t the first problem I have encountered. Needless to say, yet again I have another. I am trying to get physics to work in ursina so cubes or other entities can have mass and fall. I have heard that Bullet-for-ursina is a good idea as listed in here https://github.com/LooksForFuture/Bullet-for-ursina. Though, ursina and this GitHub have very little documentation, especially the GitHub. Anyways, I have tried using the built in ursina colliders as well as the ones for the BulletWorld to no avail. My problem that is occurring is that when I add the Mesh collider to my enemy, 1 of a couple things will happen.
