## Parameters

### Object 1

Parameter ID: `GV_COLLISION_INPUT_OBJECT1`

### Object 2

Parameter ID: `GV_COLLISION_INPUT_OBJECT2`

see also [Node Properties / Collision Type: Object](https://help.maxon.net/c4d/en-us/Content/html/GVCOLLISION-ID_GVPROPERTIES.html.md).

### Tolerance

Parameter ID: `GV_COLLISION_INPUT_TOLERANCE` · Range: [0.00..+∞]

see also [Node Properties / Collision Type: Tolerance](https://help.maxon.net/c4d/en-us/Content/html/GVCOLLISION-ID_GVPROPERTIES.html.md).

### Collision

Parameter ID: `GV_COLLISION_OUTPUT`

Outputs a value of the type Boole which indicates whether the objects are currently colliding.

### Distance

Parameter ID: `GV_COLLISION_OUTPUT_DISTANCE` · Range: [-∞..+∞]

Outputs the smallest distance between the objects (works in the Sphere and Distance modes only).

### Polygon Index 1

Parameter ID: `GV_COLLISION_OUTPUT_INDEX1` · Range: [-2147483648..2147483647]

If a collision has been detected, this port outputs the index number of the polygon in Object 1 that collided first (provided Collision Type is set to Object or Distance).

### Polygon Index 2

Parameter ID: `GV_COLLISION_OUTPUT_INDEX2` · Range: [-2147483648..2147483647]

If a collision has been detected, this port outputs the index number of the polygon in Object 2 that collided first (provided Collision Type is set to Object or Distance).

### Point 1

Parameter ID: `GV_COLLISION_OUTPUT_POINT1` · Range: [XYZ ]

This port only works when **Collision Type** is set to **Distant** and will return the position vector of the point of the nearest object (Input Port: Object 1). The objects should not collide with each other!

### Point 2

Parameter ID: `GV_COLLISION_OUTPUT_POINT2` · Range: [XYZ ]

This port only works when **Collision Type** is set to **Distant** and will return the position vector of the point of the second nearest object (Input Port: Object 2). The objects should not collide with each other!
