## Node Properties

### Object A

Parameter ID: `COLLISION_NODE_OBJECT_A`

### Object B

Parameter ID: `COLLISION_NODE_OBJECT_B`

If each field contains an object the Node will supply collision information for these two objects only. If only one of the fields contains an object, only collisions with this object will be registered. If neither of these fields contains an object ALL collisions will be registered and evaluated.

### One Collision per Pair

Parameter ID: `COLLISION_NODE_SINGLE_COLLISION`

When two objects collide they most often do so with more than 1 collision. If this option is enabled only a single collision between the two objects will be registered.
