Trying to rotate a 2D sprite
I've got this code attached to a 2D sprite that I want to rotate. So far I'm working on making it rotate left when the left arrow key is pressed. I get no parsing errors, but when I run the game, the code doesn't work. Any idea what I'm doing wrong?
using UnityEngine;
using System.Collections;
public class Rotate : MonoBehaviour {
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if (Input.GetButtonDown ("left"))
RotateLeft();
}
void RotateLeft () {
Quaternion theRotation = transform.localRotation;
theRotation.z *= 270;
transform.localRotation = theRotation;
}
}
Best Answer
void RotateLeft () {
transform.Rotate (Vector3.forward * -90);
}
Looks like I have another problem now...
UnityException: Input Button left is not setup.
To change the input settings use: Edit -> Project Settings -> Input
Alright, it works now. Thanks for your help, everybody!
Instead of subtracting 90 from the forward direction, you can use Vector3.forward and vector3.back:
//rotate counterclockwise
transform.Rotate (Vector3.forward);
//rotate clockwise
transform.Rotate (Vector3.back);
