# setPhysicsCollisionFlag

*Command · PhysX · Arma 3 v2.18*

Locality: arguments **global** · effect **local**

## Description

Sets physics collision flags for PhysX and geometry LODs. Roadway LOD interactions remain.

For example, if collision is disabled for a house, it is now possible to walk through its walls but still possible to walk on its floors.

> [!NOTE]
> Use the [allLODs](../commands/allLODs.md) command to check if an object has a roadway LOD (normally, if an object is intended to be walkable, it does have a roadway LOD).

## Syntax

```sqf
object setPhysicsCollisionFlag value
```

**Parameters:**

- `object`: [Object](../topics/Object.md)
- `value`: [Boolean](../topics/Boolean.md) - [true](../commands/true.md) to enable collision, [false](../commands/false.md) to disable it

**Returns:** [Nothing](../topics/Nothing.md)
