a change 3D object button into ImageTarget example on unity3D

By airstanair on Mon, 12/03/2012 - 21:10

I completed an example for ImageTarget on unity 3D? but I found a javascript method that can change 3D object with buttons.

I try it ,and it's work. But there is a problem.

When I use phone camera to focus the trackimage and use the change button, it's working, I can change 3D object on my phone screen.

But~ when I don't focus the trackimage, the 3D object is still in my phone screen. How to slove it?  help me~thank you.

-------js code(I put it in AR camera)----

var ObjectA: GameObject; var ObjectB: GameObject; var ObjectC: GameObject; var ObjectD: GameObject; var TempActor: String = ""; private var Clone: GameObject;    function Start() { SwitchActor("A"); }  function Update() {}  function OnGUI() { GUI.BeginGroup(Rect(20, 20, 200, 315));  GUI.Box(Rect(0, 0, 200, 315), "Actor List"); if (GUI.Button(Rect(20, 30, 160, 50), "Actor A")) SwitchActor("A"); if (GUI.Button(Rect(20, 100, 160, 50), "Actor B")) SwitchActor("B"); if (GUI.Button(Rect(20, 170, 160, 50), "Actor C")) SwitchActor("C"); if (GUI.Button(Rect(20, 240, 160, 50), "Actor D")) SwitchActor("D"); GUI.EndGroup(); }  function SwitchActor(mag) { if (mag != TempActor) { Destroy(GameObject.Find("Actor" + TempActor)); switch (mag) { case "A": TempActor = "A"; Clone = Instantiate(ObjectA, Vector3(0, 0, 0), Quaternion.identity); Clone.name = "ActorA"; print("A"); break;  case "B": TempActor = "B"; Clone = Instantiate(ObjectB, Vector3(0, 0, 0), Quaternion.identity); Clone.name = "ActorB"; print("B"); break;  case "C": TempActor = "C"; Clone = Instantiate(ObjectC, Vector3(0, 0, 0), Quaternion.identity); Clone.name = "ActorC"; print("C"); break;  case "D": TempActor = "D"; Clone = Instantiate(ObjectD, Vector3(0, 0, 0), Quaternion.identity); Clone.name = "ActorD"; print("D"); break; } } }
