Audio track based on integer value. (integer value changed by GUI.Button)

Question

I want to have three buttons that each when selected change the current audio track to track one, track two, and track three respectively. To do this, I defined a var for each of the audio sources along with defining an integer called SelectedTrack in order to make it so by clicking on a button the integer would be set to a value of 1,2, or 3 and that if SelectedTrack=1 then track one would play and so on for track two and three.

This is the code that I have right now for my GUI setup:

var PauseWallpaper : GUISkin; var TrackOne : AudioSource; var TrackTwo : AudioSource; var TrackThree : AudioSource; var SelectedTrack : Int = 1; static var ToggleMenu : boolean = false; function Update() { if(Input.GetKeyDown(KeyCode.Escape)){ GetComponent("MouseLook").enabled = !GetComponent("MouseLook").enabled; GetComponent("Camera").enabled = !GetComponent("Camera").enabled; PauseGame(); } if(SelectedTrack=1){ audio.Play(TrackOne); } if(SelctedTrack=2){ audio.Play(TrackTwo); } if(SelctedTrack=3){ audio.Play(TrackThree); } }

static function PauseGame() { if(!ToggleMenu) { Time.timeScale=0; AudioListener.pause = true; ToggleMenu=true; } else { Time.timeScale=1; AudioListener.pause = false; ToggleMenu=false; } }

These are the errors that currently come up : (14,25): BCE0044: expecting ), found '='. (14,26): BCE0043: Unexpected token: 1. (15,29): BCE0044: expecting :, found ';'.

Lines 43 to 51 is where I want to change the integer value when each button is pressed. and 14 to 22 is where I want the current track playing to be based off of the integer value.

Any help figuring this out is greatly appreciated.

Answer 1

if you use if(...), you should use the == , example - if (SelectedTrack == 1){ your script in here ... }

And play other audio , you should use the AudioChip and audio.PlayOneShot,

example - var TrackOne : AudioChip;

audio.PlayOneShot(TrackOne);

var PauseWallpaper : GUISkin;

// Put your audio clip in the TrackOne, TrackTwo and TrackThree, but not the audio source

var TrackOne : AudioClip;

var TrackTwo : AudioClip;

var TrackThree : AudioClip;

var SelectedTrack : Int = 1;

static var ToggleMenu : boolean = false;

function Update() { if(Input.GetKeyDown(KeyCode.Escape)) { GetComponent("MouseLook").enabled = !GetComponent("MouseLook").enabled; GetComponent("Camera").enabled = !GetComponent("Camera").enabled; PauseGame(); }

 if(SelectedTrack == 1)
 {
     audio.PlayOneShot(TrackOne);
 }

 if(SelectedTrack == 2)
 {
     audio.PlayOneShot(TrackTwo);
 }

 if(SelectedTrack == 3)
 {
     audio.PlayOneShot(TrackThree);
 }

static function PauseGame() { if(!ToggleMenu) { Time.timeScale=0; AudioListener.pause = true; ToggleMenu=true; } else { Time.timeScale=1; AudioListener.pause = false; ToggleMenu=false; } }

function OnGUI() { if(GUI.Button(Rect(0,0,100,50),"Track One")) { SelectedTrack = 1; }

 if(GUI.Button(Rect(0,0,100,50),"Track Two"))
 {
     SelectedTrack = 2;
 }

 if(GUI.Button(Rect(0,0,100,50),"Track Three"))
 {
     SelectedTrack = 3;
 }

 if(ToggleMenu) //if ToggleMenu = true execute follwing.
 {
     GUI.skin = PauseWallpaper;

     GUI.Box(Rect (0,0,Screen.width,Screen.height), "PAUSED");

     if(GUI.Button(Rect (Screen.width / 2 - 50, Screen.height / 2 - 75, 100, 50),    "Exit Program"))
         Application.Quit();

     if(GUI.Button(Rect (Screen.width / 2 - 50, Screen.height / 2 - 25, 100, 50), "Level Select"))
     {
         //script
     }
 }

}

There are some script reference - AudioClip and PlayOneShot
