Unity 3D Game Engine – Android – Touch Drag – Moving a 3D Object – JS

Inside Hierarchy create:

– Cube (Game Object), position X=0 Y=0.5 Z=0

– Main Camera, move it to see the Cube from top; position X=0 Y=8 Z=0, rotation X=90 Y=0 Z=0, attach the script ‘TouchMove.js’

TouchMove.js

var object : GameObject;

function Update () {
   
	for (var touch : Touch in Input.touches){
		var ray = Camera.main.ScreenPointToRay(touch.position);
		var hit : RaycastHit;
		if (Physics.Raycast (ray, hit, 100)) {
			if(touch.phase == TouchPhase.Began || touch.phase == TouchPhase.Moved) {
				var cameraTransform = Camera.main.transform.InverseTransformPoint(0, 0, 0);
				object.transform.position = Camera.main.ScreenToWorldPoint(new Vector3 (touch.position.x, touch.position.y, cameraTransform.z - 0.5));
			}
		}
	}
}
