Question by Kameron23322 · Apr 04, 2014 at 07:52 PM · androidbuttonactivation

how to activate a object with button?

So I use a button assest for android an so my button looks like this and I want to activate a object thats deactivated with "gameObject.SetActive (false);.

using UnityEngine; using System.Collections;

public class spawnParachute : MonoBehaviour {

     //cube I want to spawn
 public GameObject Cube;

 //button to use for going to the game
 public EasyButton parachute;
 
 
 //this is the buttons name after "string"
 void On_ButtonUp (string parachute)
 {
     // thats the button and string
     if (parachute == "parachute")
     {
                     //This is the only part worth looking at
         GameObject.Find("Cube").SetActive (true);
     }
 }

}

I get the error "object refrence not set to instance of object"

GameObject.Find will only retrieve objects that are enabled.

You can find this information in the unity scripting reference: http://docs.unity3d.com/Documentation/ScriptReference/GameObject.Find.html

"This function only returns active gameobjects."

What you will want to do is keep a reference to the object before you disable it. Then use that reference to re-enable it.

The code would look something like this:

 public class Temp : MonoBehaviour
 {
     private GameObject m_cube;
 
     // Use this for initialization
     void Start ()
     {
         m_cube = GameObject.Find("Cube");
         m_cube.SetActiveRecursively(false);
     }
 
     void EnableObject()
     {
         m_cube.SetActiveRecursively(true);
     }
 }
