Obstacle Sphere

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

  • For the sphere-shaped nodes (huge boulders, bushes and so on) that are placed inside a navigation area and should be bypassed.
  • For the areas (lakes and so on) that should be bypassed.

Adding Obstacle Sphere

To add a sphere obstacle to the scene via UnigineEditor:

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

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

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

Editing Obstacle Sphere

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

Obstacle Obstacle mask. The obstacle mask of the obstacle sphere 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 spheres that should be ignored during pathfinding.
Radius Radius of the obstacle sphere in units.
