Left and Right Arrow Keypress for navigation between scenes.

Hi,

I need help urgently as i am new in unity3d.

i have 3 scenes, each scene has a left and right button.

I wanted this: If i am in scene1,and i press the right arrow button, it should do a Application.LoadLevel to scene 2. and if i press left arrow, i move back to previous scene.

But the strange thing is that, now with three scene setup and i go to scene 1 and when i press the right arrow, it moves me from Scene1 to scene2 to scene 3, without stopping at scene2. the left arrow bring me directly to scene 1 without stopping at scene2.

i tried forcing the variables KeypressedFw and KeypressedBck to false but seems does't work. please help.

here is the js for scene1, that i attached to my Main Camera.

function OnGUI() {

var keyPressedFw; var keyPressedBck;

keyPressedFw = false; keyPressedBck= false;

keyPressedFw = (Event.current.keyCode == KeyCode.RightArrow)? true : false; keyPressedBck= (Event.current.keyCode == KeyCode.LeftArrow)? true : false;

GUI.Button(Rect((Screen.width / 2) - 75, (Screen.height / 2) -50, 150, 100), "Scene 1"); GUI.Button(Rect((Screen.width / 2) - 150, (Screen.height / 2) -50, 50, 100), "Bck"); GUI.Button(Rect((Screen.width / 2) + 100, (Screen.height / 2) -50, 50, 100), "Fwds");

if (keyPressedBck == true) {
           }
if (keyPressedFw == true) {
    //  yield WaitForSeconds(.5);
     Application.LoadLevel ("scene2");
    }

} //onGui

Peviously i was using The following code that allows me to even use the mouse to change scenes:

function OnGUI() {

var keyPressedFw = (Event.current.keyCode == KeyCode.RightArrow)? true : false; var keyPressedBck= (Event.current.keyCode == KeyCode.LeftArrow)? true : false;

GUI.Button(Rect((Screen.width / 2) - 75, (Screen.height / 2) -50, 150, 100), "Scene 1");

if (keyPressedBck || GUI.Button(Rect((Screen.width / 2) - 150, (Screen.height / 2) -50, 50, 100), "Bck")) { } if (keyPressedFw || GUI.Button(Rect((Screen.width / 2) + 100, (Screen.height / 2) -50, 50, 100), "Fwds")) { // yield WaitForSeconds(.5); Application.LoadLevel ("scene2"); } }

please somebody help.
