[1.7.10] Set view angle (Yaw) as the direction that I'm walking to

Hey.

I'm making a mod that includes a pathfinding algorithm, the pathfinding works great, but - since I don't handle the view angle it stays in the same place, I tried to modify the look angle using this:

player.rotationYaw = (float)(Math.atan2(direction.xCoord, direction.zCoord) * 360);

player is the player, direction is a vec3 which I'm using to set velocity.

I checked the result that I'm getting from the atan, most of them are below 1 but they are in range of -2~2

Any ideas?

Thank you.
