Rotating object using mouse movement

Questions & Answers
1

I’ve been trying to code a “physics gun” from garrys mod into my game, though i can’t seem to get the object rotating right. So i want the user to be able to hold down “e” when an object is grabbed to then rotate it using the mouse. Based on an earlier question (How to rotate an object's X, Y, Z based on mouse movement - Questions & Answers - Unity Discussions) i found out how to achieve this though it simply doesn’t work for me. Nothing happens… This is a rough script i wrote to try it out, what am i doing wrong? :slight_smile:

#pragma strict
var speed = 5.0f;

var toolEnabled : String = "physicsGun";

var objectSelectParticles : Transform;

private var selectedObject : Transform;
private var trackObject = false;

function Update ()
{
	if (toolEnabled == "physicsGun")
	{
		//Raycast for the object we wish to manipulate
		if (Input.GetMouseButtonDown(0))
		{
			var gunHit : RaycastHit;
			if (Physics.Raycast (transform.position, transform.TransformDirection(Vector3.forward), gunHit) && gunHit.transform.tag == "Prop")
			{
				//Enable the variable that is gonna alow for Update
				trackObject = true;
				//Make selectedObject date be = the data from raycast
				selectedObject = gunHit.transform;
				Instantiate(objectSelectParticles, gunHit.point, selectedObject.transform.rotation);
				selectedObject.parent = transform;
				//Make it kinematic
				selectedObject.gameObject.rigidbody.isKinematic = true;
			}
		}
		
		if (trackObject == true)
		{
			//THIS IS WHERE I WANT THE ROTATING TO HAPPEN.
			if (Input.GetKeyDown(KeyCode.E))
			{
				selectedObject.transform.Rotate(Vector3(Input.GetAxis("Mouse Y"), Input.GetAxis("Mouse X"), 0) * Time.deltaTime * speed);
			}
			
			
			if (Input.GetAxis("Mouse ScrollWheel") < 0) // back
	        {
	            selectedObject.transform.position = Vector3.MoveTowards(selectedObject.transform.position, transform.position, 5.0f*Time.deltaTime);
	        }
		}
		
		//Turn everything off again
		if (Input.GetMouseButtonUp(0))
		{
			trackObject = false;
			if( selectedObject != null)
			{
				selectedObject.parent = null;
				selectedObject.gameObject.rigidbody.isKinematic = false;
			}
		}
	}
}

function ToolHandling (string)
{
	Debug.Log("Tool = " + string);
	toolEnabled = string;
}

Your problem is that you are using Input.GetKeyDown(). Use Input.GetKey() instead. GetKeyDown() only returns true in the frame that that the key was pressed.
