simple TOUCH of a 3D object in iOS
Hi,
I tried to find out how to simply detect the touch of a 3D object with iOS. But I could not make it work on device.
Can someone please help me out:
Say there is a cube called "cube" and the user touches it on a iOS device.
How can catch this event??
thank you so much for your help!!!
Putting together Jessy's answer in to a piece of code. The Update() and TapSelect() are put on any ONE Object in the scene. I put it ion my main game controller. The Selected goes on each object you to be able to select.
// Update is called once per frame void Update () { TapSelect(); }
void TapSelect() { foreach (Touch touch in Input.touches) { if (touch.phase == TouchPhase.Began) { Ray ray = Camera.main.ScreenPointToRay(touch.position); RaycastHit hit ; if (Physics.Raycast (ray, out hit)) { hit.transform.SendMessage("Selected"); } } } }
public void Selected(){
Debug.Log("Selected",this);
}
This is in c#. When the screen is tapped the TapSelect does a Raycast and if anything is hit it sends the Selected() message to the transform.
This is great, thanks. I am using it to send a "On$$anonymous$$ouseDown" message ins$$anonymous$$d, so it serves as a transparent drop in replacement.
Cast a ray from the position of a touch.

That code uses ScreenPointToRay, which you should, but it also uses Input.mousePosition, which is not right on iOS. The thing you'll need to replace it with is a Touch.position. There are some examples in the documentation about how to code input for iOS:
