How to turn on/off multiple lights using GUI buttons?

Question

Hi everyone,

I'm making a sample test on switc$$anonymous$$ng an on/off multiple lights using 1 GUI button. Right now I'm using javascript because I'm still learning unity. Could anybody give me some sample codes that I' could use. Thanks.

That should do it.

 var lights : Light[];
 
 function OnGUI()
 {
     var on = lights[0].enabled;
 
     if( GUI.Button( Rect( 10, 10, 100, 100 ), "Turn " + (on ? "off" : "on") + " the lights !" ) )
     {
         for( var i = 0; i < lights.Length; i++ )
             lights[i].enabled = !on;
     }
 
 }

Hi sir,

When I try to put the codes on to my unity, this errors showed up:

Assets/Scripts/Control_Lights.js(7,39): BCE0043: Unexpected token: 100.

Assets/Scripts/Control_Lights.js(7,94): BCE0043: Unexpected token: ).

Assets/Scripts/Control_Lights.js(9,9): BCE0043: Unexpected token: for.

Assets/Scripts/Control_Lights.js(9,12): UCE0001: ';' expected. Insert a semicolon at the end.

Assets/Scripts/Control_Lights.js(9,14): BCE0043: Unexpected token: var.

Assets/Scripts/Control_Lights.js(9,18): BCE0044: expecting ), found 'i'.

Assets/Scripts/Control_Lights.js(9,48): BCE0043: Unexpected token: ).

Assets/Scripts/Control_Lights.js(13,1): BCE0044: expecting EOF, found '}'.

Is there anything that I do wrong? But anyways, thanks for helping me on my script.

Well, coding on the fly is risky business. I should have tested it first Anyway, I forgot a some parenthesis in the if line. I fixed the code.
