====== Displaying hint icons over active hotspots ======

If you want to implement functionality similar to active object highlighting in Tunguska, add the following piece of code to game.script:
<code script>var ShowingHintIcons = false;
////////////////////////////////////////////////////////////////////////////////
function ShowHintIcons()
{
       // Small fix by metamorphium. Feel free to ignore
      if (Scene.GetLayer("hints") == null) ShowingHintIcons = false;
      //End Fix
 
    // make sure we're only displaying the icons once
    if(!ShowingHintIcons)
    {
        ShowingHintIcons = true;
        
        // create a new top-level layer
        var HintLayer = Scene.AddLayer("hints");
        
        // traverse through all scene entities
        var MainLayer = Scene.MainLayer;
        var i;
        for(i = 0; i < MainLayer.NumNodes; i = i + 1)
        {
            var Node = MainLayer.GetNode(i);
            AddHintIcon(HintLayer, Node);
        }
        
        // traverse through all free entities/actors
        for(i = 0; i < Scene.NumFreeNodes; i = i + 1)
        {
            Node = Scene.GetFreeNode(i);
            AddHintIcon(HintLayer, Node);
        }
 
        // rotate the icons for a moment
        for(var t = 0; t <= 360; t = t + 15)
        {
            for(i = 0; i < HintLayer.NumNodes; i = i + 1)
            {
                var Icon = HintLayer.GetNode(i);
                Icon.Rotate = t;
            }        
            Sleep(50);
        }
        
        // delete the entire layer
        Scene.DeleteLayer(HintLayer);
        
        ShowingHintIcons = false;
    }
}
 
////////////////////////////////////////////////////////////////////////////////
function AddHintIcon(Layer, Node)
{
    // we're only interested in interactive visible entities
    if(Node.Type!="entity" || !Node.Interactive || !Node.Active) return;
    
    // create the hint icon
    // you could improve this, e.g. to display different icons depending on the 'Node' capabilities
    var Icon = Layer.AddEntity("icon");
    Icon.SetSprite("sprites\system\cur_wait.sprite");  // Replace this with a sprite that should mark the hotspots
    Icon.X = Node.X;
    Icon.Y = Node.Y - (Node.Height / 2);
    Icon.Active = true;
    Icon.Interactive = false;
    Icon.Scalable = false;
    Icon.Rotatable = true;    
}</code>

Now the only thing you need to do is to call this code somewhere. For example, if you want to display the hint icons when the player presses the spacebar, edit game.script, find the on “**Keypress**” handler, and add something like:
<code scipt>if(Keyboard.KeyCode==VK_SPACE) ShowHintIcons();</code>

This script is based on the original code written by Mac.
