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.

To add a sphere obstacle to the scene via UnigineEditor:

Run UnigineEditor.
On the Menu bar, click Create -> Navigation -> Obstacle Sphere.
Click somewhere in the world to place the obstacle.

A new obstacle sphere is added to UnigineEditor and you can edit it via the Parameters window. See also the example on obstacle usage.

On the Node tab of the Parameters window, you can adjust the following parameters of the obstacle sphere:

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 is not 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.
