How can I rotate the player to fixed rotation?

Hi guys

I recently started with untiy and I'm trying to recreate PacMan. Right now I'm working on the PlayerMovement script and have a problem with the rotation.

I want the character to always look at the direction it moving. In PacMan there are only 4 directions (Up, Left, Down, Right)

I tried a lot of stuff already. I have to add to this that, even if I have some basic programming knowledge, I can't wrap my head around the whole rotation/quaternion thing.

i.e. I wanted to use Quaternion.slerp but with that I didn't know how I can set the target direction

Please help me or if possible, lead me to a pleace, where the whole rotation thing is explained in a way that I can understand it.

Thanks a lot.

This is what I have so far: var player : Transform; var moveSpeed = 10; var rotateSpeed = 10;

//This was my idea to have fixed points to rotate to... var directionLeft = Vector3(1,0,0); var directionRight = Vector3(-1,0,0); var directionUp = Vector3(0,0,-1); var directionDown = Vector3(0,0,1);

function Update(){ var controller : CharacterController = GetComponent(CharacterController);

//this is just for the "up" direction if (Input.GetButton("Move Up")) { controller.SimpleMove(directionUp * moveSpeed); //here would be the roationscript }
