How to point in direction of arrow keys?

Questions & Answers

Hello everyone I’m wondering how to make my character face the direction of the arrow keys for example when I press the right arrow key I want my character to face 90 degrees on the Y axis and when I press the down down arrow key he faces 180 degrees but when I press both I want him to face 135 degrees. How would I do this?

To get the desired effect, you need to do two things-

first, in your script-

Vector3 movementDirection = new Vector3(Input.GetAxis("Horizontal"), Input.GetAxis("Vertical"), 0);
Vector3 realDirection = Camera.main.transform.TransformDirection(movementDirection);
// this line checks whether the player is making inputs.
if(realDirection.magnitude > 0.1f)
{
    Quaternion newRotation = Quaternion.LookRotation(realDirection);
    transform.rotation = Quaternion.Slerp(transform.rotation, newRotation, Time.deltaTime * 10);
}

EDIT: Code fixed- now with 100% more sanity.

EDIT EDIT: Code augmented- now doesn't reset angles.

Now, doing it that way will cause your player to smoothly rotate all the way around the axis- which is good under most circumstances, but sometimes you don't want this (retro-inspired movement style, 8-directions). To make it rotate sharply, change the transform.rotation line to

transform.rotation = newRotation;

And then instead of using

Input.GetAxis("whatever");

use

Input.GetAxisRaw();

which returns a 1 or 0 value.
