User input display

There is only one way that >I< (and emphasis on "I") I know of is if / if else. I have done lots of searching on this topic, and, haven't really found anything. I don't mean to mislead you or anything, so, you might want to do some more searching and ask around. That, or hopefully someone else can post a better answer than this one .

 function Update ( )
 {
    if ( Input.GetKey ( KeyCode.C ) ){
       //Do GUI stuff
    }
 
    if ( Input.GetKey ( KeyCode.B ) ){
       //Do GUI stuff
    }
 
    if ( Input.GetKey ( KeyCode.C ) ){
       //Do GUI stuff
    }
 }

Alternatively, If you want to keep Update a little cleaner, just create another function to pre-store variables, or use Start ...

 var KeyArray = new Array ( ) ;
 function Start ( )
 {
    KeyArray.Add( KeyCode.A ) ;
    KeyArray.Add( KeyCode.B ) ;
    KeyArray.Add( KeyCode.C ) ;
 
 }
 
 function CheckKeys ( )
 {
    for ( var _keys ; _keys in KeyArray; _keys ++ )
    {
       if ( Input.GetKey ( KeyArray [ _keys ] ) )
       {
          //GUI CODE
       }
 
    }

    yield WaitForSeconds ( 0.1 ) ; // May cause key latency, but better performance. See if this causes an issue for you.
 }
 
 //Though I am not sure if the second method is memory efficient. You will have to test that out.
 
 function Update ( )
 {
    CheckKeys ( ) ;
 }
