Physics3D how to set fixedRotation such that my character 3D model will not rotate after collision?

In Physics3D how to set fixedRotation such that my character 3D model will not rotate after collision?

I always want my 3D character to stand up but now when my character hits some other objects in the game it rotates incorrectly.

I want my 3D character to bound back but it won't fall down.

In cocos creator, there is a feature called fixedRotation but I cannot find this in axys:

      When doing platform jumping games, you usually don't want the rotation property 
      of the main character to be added to the physics simulation, because it
      will cause the main character to fall over during the movement, so you
      can set fixedRotation of the rigid body to true to fix the rotation, the code
      example is as follows:

                rigidbody.fixedRotation = true;

@cchuicchui
Can you make an (github) or cpp-tests example?

You'll most likely need to call this method:

void setAngularFactor(const cocos2d::Vec3& angFac);

The following code works like a charm!

      rigidBody->setAngularFactor(Vec3(0, 0, 0));
