If you are too lazy to do the math to orient an object to a specific direction, this tip is useful for your.
The Transform objects in unity have the Forward, Up and Right properties. You probably don’t know that they are not only accessors but also mutators! You can simply assign a direction vector to an object’s Forward direction and the object will face that direction:
Vector3 dir = new Vector3(10, 0, 10); this.Transform.Forward = dir;
This can be handy sometimes, especially when you want to use the Kinect sensor inside the game. If the players arm direction signifies the orientation of something (eg. a sword), this tip saves you some time.
