Left and Right Arrow Keypress for navigation between scenes.

[system]

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.

regards nigel

OnGUI may be called several times per frame. If you load another scene, its OnGUI will be called and if the code is about the same, the event will be fired quickly enough that it will register the arrow key and load the next scene. Try adding a timer or wait of some kind before you start checking for the user input.
