Filter group

[ViachaslauBusel]

How to create a filter that is used to selectively ignore objects when casting a ray. I want to split the objects in the simulation into two groups, and selectively ignore one of the groups when casting a ray. thanks

IRayHitHandler has an AllowTest callback that is called before doing any testing. It passes in a collidable reference you can use to look up filter data.

Exactly how the filtering data is stored or computed is up to you. It can be helpful to have a mapping from collidable reference to other data- CollidableProperty<T> is a helper class that exists for that purpose. For example, to implement narrow phase pair filtering, the ragdoll demo uses it:

bepuphysics2/Demos/Demos/RagdollDemo.cs

Line 97 in 11f7e09

public CollidableProperty<SubgroupCollisionFilter> CollisionFilters;
