C# moveOnMouseClick Rotation

Questions & Answers

Hi everyone, I’m trying to edit the moveOnMouseClick from the Unify wiki so it won’t rotate the camera. But if I make it so it only rotates the object then the object doesn’t rotate. Any ideas?

/*

 * Para usá-lo, adicione esse script ao gameObject que você quer mover

 * This script moves the GameObeject when you

 * Simply attach it to the gameObject you wanna move (player or not)

		//	myTransform.position = Vector3.MoveTowards(myTransform.position, destinationPosition, moveSpeed * Time.deltaTime);

		// To prevent code from running if not needed
		if(destinationDistance > .5f){

Try this:

using UnityEngine;
using System.Collections;

public class NoRotation : MonoBehaviour {

	private Quaternion q;
	
	void Start () {
		q = transform.rotation;
	}
	
	void Update () {
		transform.rotation = q;
	}
}

Or you could figure out and fix the null reference error.

If I got your question right you want to rotate the gameObject, but not the camera (it should be fixed like in Pokémon Colosseum or Diablo). That means that you’ll need to use one script for the gameObject and one for the camera. The script you posted for the gameObject will probably work fine (though it could be shortened). Here is the script for the camera: Camera Movement - Pastebin.com

Note: The camera should NOT be a child to the player
