InteractionGroup

Specifies which Colliders a collider will collide with, by using bit masks of InteractionLayers. This object stores two InteractionFields:

• memberships - which layers this collider is a part of

• filter - which layers this collider may collide with

If a collider collides with layer X, it means that the collider will collide with any others which have bit X set in their memberships field.

If we want to specify a collider which is part of the layers [0, 2, 3] and can collide with the layers [2], we specify the fields as:

          index  3 2 1 0
    memberships  1 1 0 1
         filter  0 1 0 0

which is written as

InteractionGroup(
    memberships = InteractionField.fromRaw(0b1101),
    filter = InteractionField.fromRaw(0b0100),
)

For details on what this interaction group will do exactly, see Collider.
