I'm trying to keep track of a position 1 block behind me from the direction I look, but I've no idea how to do this smoothly! Code: Location Target = player.getLocation(); double yaw = Target.getYaw(); double x = 0, z = 0; // calculate X, Z value behind player based on vertical yaw, direction player is facing? Target.add(x, 0.0D, z); entity.teleport(Target); I'm sure this has to be a common function in many games where you calculate a radial position/coord around a player based on their face direction, can anyone point me to what this calculation would be called? Or.. how to do this? EDIT: Code: Location Target = p.getLocation(); double yaw = Target.getYaw() - 85; double x = 0, z = 0; x=Math.cos(yaw*0.02F)*0.2; z=Math.sin(yaw*0.02F)*0.2; Target.add(x, 0.0D, z); entity.teleport(Target); This is doing what I needed! It's keeping an entity following just behind me and stays behind me no matter where I turn.
