Motion Controller, Unity NavMesh and RAIN Example Motor

[blockcipherParticipant]

Here is a simple Motor I made to make RAIN work with Motion Controller (https://www.assetstore.unity3d.com/en/#!/content/15672) and the Unity NavMesh.

1) Place a RAIN AI component on your character (Menu > RAIN > Create New > AI)
2) a) Place a MotionController on your character (Menu > Component > ootii > Motion Controller)
b) Make sure MC placed a NavMesh Input Source on your character. If it didn’t, add one.
3) Place a NavMeshAgent on your character
3) Setup the Motion Controller however you want it
4) Change the Motor (under the RAIN AI Motion tab) to McRAINNavMeshMotor (code follows) (at the moment it doesn’t have any exposed properties that will show up in the inspector)

Since the controller uses Root Motion to control speed, you can use a “Speed Multiplier” variable, set up in the Animator, to control the character speed. This is (I believe) a new feature and is present in Unity version (5.3.4p4)

The position data is fed to the NavMeshAgent from RAIN through the MotionController.

Have fun! If you have any problems you can ask here or send me an email at (anarchyrising420@gmail.com)
