I’m trying to put together a power up system in an efficient/modular way. I have a settings file attached to an empty game object in the scene. By plan was to define the various power ups in this settings file as follows:

#pragma strict

var powerup : Powerup;

class Powerup{
 
 var boost : Boost;

    class Boost{
    
     var duration : float = .8;
    
     var texture : Texture2D;
    
     // var scriptToAttachToPlayer : (?);
    

   }
   
   var blast : Blast;

    class Blast{
    
     var duration : float = .8;
    
     var texture : Texture2D;
    
     // var scriptToAttachToPlayer : (?);
    

   }
 
 var hide : Hide;

    class Hide{
    
     var duration : float = 4.0;
    
     var texture : Texture2D;
    
     // var scriptToAttachToPlayer : (?);
    

   }


}

Duration refers to how long the power up will remain active once triggered. Texture is a bitmap icon representation of the powerup.

What I’d like to be able to do is set things up so that I can use the inspector to drag arbitrary scripts into a scriptToAttachToPlayer variable, per powerup, and that later these scripts will be programmatically attached/removed from players when the relevant powerup is activated/deactivated. I’m not sure how to achieve this though.

Is this possible? Or should I be approaching this in a different way?

What you are looking for as a variable type is Type, but you would have to do a custom inspector to assign it, the built in one doesn’t do that. You could just have a string variable and type in the name of the script.

Also, it looks like you should be having a base class containing that duration, texture and script though - presumably other things about this would be different, but those bases would be the same.

   class baseClassName 
   {
        var duration : float;
        var texture  : Texture2D;
        var script   : String;
   }

   class Boost extends baseClassName
   {
   }

For the data I have that I want to assign in this way I tend to use ScriptableObjects. This may be too heavy weight for your needs however, but it would certainly work.

There’s a tutorial here on ScriptableObjects:

I confess I have not read it, but it’s too in-depth to talk about in an answer - I throw it out there as a research topic :slight_smile:
