Obstacle Box

An obstacle box is a cuboid-shaped obstacle that is detected and bypassed by other objects during pathfinding. The obstacle box can be added, for example:

  • For the cuboid-shaped nodes (buildings, old-fashioned cars, fences and so on) that are placed inside a navigation area and should be bypassed.
  • For the areas (rivers, swimming pools and so on) that should be bypassed.

Adding Obstacle Box

To add an obstacle box to the scene via UnigineEditor:

  1. Run UnigineEditor.
  2. On the Menu bar, click Create -> Path -> Obstacle Box.

  3. Click somewhere in the world to place the obstacle.

The new obstacle box will be added to UnigineEditor and you will be able to edit it via the Nodes panel. See also the example on obstacle box usage.

Editing Obstacle Box

On the Obstacle tab of the Nodes panel, you can adjust the following parameters of the obstacle box:

Obstacle Obstacle mask. The obstacle mask of the obstacle box must match the obstacle mask of the route that is calculated during pathfinding. Otherwise, the obstacle will not be taken into account during pathfinding. Also by using the obstacle mask, you can specify obstacle boxes that should be ignored during pathfinding.
Size Size of the obstacle box along the axes in units.
