## Obstacle Class

### Members

## void setObstacleMask ( int mask )

Sets a new obstacle mask. The obstacle mask of the obstacle box/sphere/capsule must [match](../../../principles/bit_masking/index.md) the obstacle mask of the route that is calculated during pathfinding. Otherwise, the obstacle is not taken into account during pathfinding.
### Arguments

- *int* **mask** - The integer value each bit of which is used to set a mask.

## int getObstacleMask () const

Returns the current obstacle mask. The obstacle mask of the obstacle box/sphere/capsule must [match](../../../principles/bit_masking/index.md) the obstacle mask of the route that is calculated during pathfinding. Otherwise, the obstacle is not taken into account during pathfinding.
### Return value

Current integer value each bit of which is used to set a mask.
