Hi Guys,
I hope you can help me with this: I created a script file attached to each object. When each object pops up, I would like to be able to rotate it when I touch the IPad2 screen. I have created another program with the attached script but with no augmented reality, and it works but when I add the augmented reality libs it doesn't work anymore :(
Many Thanks for the help.
GC.
This is the script:
public var amountToInterpolate: float = 0.5f;
private var startQuat: Quaternion;
private var targetQuat : Quaternion ;
private var offSetQuat:Quaternion ;
private var lastRot:Quaternion;
private var objectHit: boolean;
function Start() {
//lastRot = transform.rotation;
lastRot = transform.localRotation;
}
function ShootRay ()
{
var ray: Ray = Camera.main.ScreenPointToRay (Input.GetTouch(0).position);
var tempQuat : Quaternion = new Quaternion();
//var hit: RaycastHit;
var rhit: RaycastHit;
if (Physics.Raycast (ray, rhit, 1000.0f)) {
objectHit = true;
}
Debug.Log("ObjectHit: " + objectHit);
if(objectHit) {
tempQuat.x = ray.GetPoint(10).x;//rhit.point.x;
tempQuat.y = ray.GetPoint(10).y;//tempQuat.y = rhit.point.y;
tempQuat.z = ray.GetPoint(10).z;//tempQuat.z = rhit.point.z;
}
return tempQuat;
}
function Update () {
//This is for the MouseDown
if(Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began) {
if(objectHit)
startQuat = transform.localRotation;//rotation;
offSetQuat = ShootRay() * startQuat;
}
//This is for MouseUp
if(Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Ended) {
lastRot = transform.localRotation;//rotation;
objectHit = false;
}
//This is for the MouseDrag
if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved) {
if(objectHit) {
Debug.Log("Dragging ");
Debug.Log("objectHIT " + objectHit);
targetQuat = ShootRay() * offSetQuat;
var endQuat: Quaternion = Quaternion.Slerp (startQuat, targetQuat, Time.time * amountToInterpolate);
//transform.rotation = endQuat;
transform.localRotation = endQuat;
startQuat = targetQuat;
Debug.Log("name: " + transform.gameObject.name);
}
}
}
Hi,
thank you for that !! It worked also with the RayCast.. but still I don't understand why my version doesn't work :(. My script is attached to each object and I ray cast the position of the touch as they do. Moreover, I compute the quaternion and use the .localRotation which is the same as using the Rotate(....., Space.self). so I don't really get....
would you be so kind if you can use it and see if it works with u?
Many thanks.
