Base class for simple RVO colliders.
This is a helper base class for RVO colliders. It provides automatic gizmos and helps with the winding order of the vertices as well as automatically updating the obstacle when moved.
Extend this class to create custom RVO obstacles.

RVO Obstacle Modes.
Determines winding order of obstacle vertices
|
protected |
Adds an obstacle with the specified vertices.
The vertices array might be changed by this function.
|
private |
Adds an obstacle.
Winding is assumed to be correct and very little error checking is done.
|
protectedpure virtual |
Called in the editor.
This function should return true if any variables which can change the shape or position of the obstacle has changed since the last call to this function. Take a look at the RVOSquareObstacle for an example.
Implemented in RVOSquareObstacle.
|
protectedpure virtual |
Create Obstacles.
Override this and add logic for creating obstacles. You should not use the simulator's function calls directly.
Implemented in RVOSquareObstacle.
|
protected |
Finds a simulator in the scene.
Saves found simulator in sim.
System.InvalidOperationException | When no RVOSimulator could be found. |
|
protectedvirtual |
Get's the matrix to use for vertices.
Can be overriden for custom matrices.
