This is mainly untested psudocode. I’m normally using c# so i hope my translation is not too bad.

  1. We put all or prefabs that we want to scroll through in a public gameobject array: GameObject myPrefabs.

  2. To loop through we declare an integer called an “activeIndex”. This is the one thats incharge of letting oyu know which prefab is currently being selected.

  3. Then the code to do it:

        var myPrefabs:GameObject[];
    var ActiveIndex:int = 0;
    var ActivePrefab:GameObject = null;
function OnGUI(){


if( 0 != ActiveIndex){
if (GUI.Button (Rect(0,0, 50,50), "Prev")){
     ActiveIndex--;
     ActivePrefab = myPrefabs[ActiveIndex];
}

    }

    if( myPrefabs.Length - 1 > ActiveIndex){

if (GUI.Button (Rect(50,0, 50,50), "Next")){
     ActiveIndex++;
     ActivePrefab = myPrefabs[ActiveIndex];         
}
}

    }
