@modoki/engine / index / packCollisionGroups

Function: packCollisionGroups()

packCollisionGroups(groups, mask): number

Pack collisionGroups/collisionMask (16-bit each) into Rapier's u32 interaction-groups format: high 16 bits = membership, low 16 bits = filter. Dimension-agnostic — Rapier's format is identical for 2D and 3D — so it lives here, the shared physics-layer module.

Parameters

groups

number

mask

number

Returns

number
