Modding:Creating a custom cloth collider

If making a custom body, you may need to create a custom cloth collider for it. You can look up any vanilla cloth collider to use as a base, but here is an example one:

The Radius attributes control how large each "sphere" of collision is. You can make it bigger or smaller to make cloth physics behave differently when colliding with it.
