Rotation Issues error CS1612:,Can't edit rotation (error CS1612)
Im trying to make a simple AI for my game but for some reason I keep getting this error:
error CS1612: Cannot modify a value type return value of `UnityEngine.Transform.rotation'. Consider storing the value in a temporary variable.
Here's my code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class livingAI : MonoBehaviour {
public Transform AI;
public void FixedUpdate ()
{
AI.rotation.y = AI.rotation.y + Random.Range (-45, 45);
AI.transform.Translate (-5, 0, 0);
}
}
I've already tried multiple solutions i found on this forum, but none of them worked.
You can't change a single value of rotation (a Qauternion). You have to assign a new rotation entirely. Also Quaternions don't use + like Vectors, if you want to add to one you need to use *. See example below:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class livingAI : MonoBehaviour {
public Transform AI;
public void FixedUpdate ()
{
Quaternion rotation = new Quaternion.Euler(0, Random.Range (-45, 45), 0);
AI.rotation.y = AI.rotation * rotation;
AI.transform.Translate (-5, 0, 0);
}
}
So Just to re-itterate on your mistake:
Wrong:
AI.rotation.y = Random.Range(-45,45)
Right:
AI.rotation = new Quaternion(AI.rotation.x,Random.Range(-45,45), AI.rotation.z, AI.rotation.w);
