Hi all, i have two game objects in my project. i want to show only one in the scene. i wrote code like this.
using UnityEngine;
using System.Collections;
public class Moon : MonoBehaviour {
public bool onoff;
public Texture2D icon;
public GameObject table;
public GameObject moon;
// Use this for initialization
void Start () {
onoff=false;
}
// Update is called once per frame
void Update () {
if (onoff == true)
moon.active = true;
table.active = false;
if (onoff == false)
table.active = true;
moon.active = false;
}
void OnGUI () {
GUI.Button (new Rect (10,10,100,50), icon);
{
onoff=true;
}
}
}
my intention is i want to show any one by default. if the user click that icon i want to show second one and first becomes turn off. if he again clicks i want first one. like that i want to show.
but i add and run this code by default i didn’t get the any one. i add all the things in the inspector view.
You use “if” without the braces, but there’s 2 instructions.
A if without braces but must be followed by only one instruction. In :
if (onoff == true)
moon.active = true;
table.active = false;
if (onoff == false)
table.active = true;
moon.active = false;
Your “table.active = false” and “moon.active = false” are out the if and will be called every frame.
Try with braces.
Other things : You button is not correct. Try with this :
if(GUI.Button (new Rect (10,10,100,50), icon))
{
onoff=true;
}
The GUI.Button must be into an if statement. Because GUI.Button return a boolean which indicate if yes or no you push the button. So i guess for your problem :
table active is always false cause out the if.
onoff = true in OnGUI is automaticly called because no if statement.
so on the update, moon.active = true is called, but moon.active = false is out the if, so neither table nor moon will be active.
Tada.
PS : Prog tips, you don’t need to write “if(onoff == true)”, just “if(onoff)”. Idem for negative comparaison “if(onoff == false)” becomes “if(!onoff)”.
Dude there is have methods for hide object on any event from the scene
gameObject.SetActive (boolean); //this will active or deactivate your object from the scene
gameObject.renderer.enabled = boolean; //this will enable/desable your object mesh
