Unpausing Game with GUI

Question

I currently have this code in my OnGUI portion of a script. The game pauses just fine when I click the button the first time, but then won't unpause upon pressing the button again. What am I missing?

    if(GUI.Button(Rect(300,5,305,25),btnTexture) && !paused)
{
Debug.Log("HIT1");
    Time.timeScale=0;
    btnTexture=playTexture;
    paused=true;
}
else if(GUI.Button(Rect(300,5,305,25),btnTexture))
{
Debug.Log("HIT2");
    Time.timeScale=1;
    btnTexture=pauseTexture;
    paused=false;
}

I would rearrange it a bit:

private var paused = false; ....

 if(GUI.Button(Rect(300,5,305,25),btnTexture))
 {
   if (!paused)
   {
 Debug.Log("HIT1");
     Time.timeScale=0;
     btnTexture=playTexture;
     paused=true;
   }
   else
   {
 Debug.Log("HIT2");
     Time.timeScale=1;
     btnTexture=pauseTexture;
     paused=false;
   }
 }

$$anonymous$$ake sure you declare 'paused' outside of your function so it persists between calls.

Paused already declared outside the function. Thanks for the attempt though :)

Found the problem. $$anonymous$$ade a mistake when I updated the code with your fix and made part of it unreachable. Works great now!

The button is only registered as pressed once in OnGUI, so your else if can never fire. Instead, do this:

Edit: I was AFK and DaveA answered with the same code. This code looks formatted, though. ;-)

function OnGUI () {
    if (GUI.Button(Rect(300,5,305,25), btnTexture) {
        if (paused) {
            Debug.Log("Unpaused");
            btnTexture = pauseTexture;
            Time.timeScale = 1;
            paused = false;
        }
        else {
            Debug.Log("Paused");
            btnTexture = playTexture;
            Time.timeScale = 0;
            paused = true;
        }
    }
}

Thank you all of you this helped me too. ^_^ I'm making a tower defense game and needed a pause for when the build menu is open and this did the trick.
