Title: Counter Class
Post by: Vincent on 2009-03-11, 07:28:54 PM

Probably a question for bluemonkmn, but if anyone else knows the answer, please help me!

Okay, first a little briefing on what I'm trying to do, maybe I'm not using the easiest way to accomplish this.  My main character has an amount of health that is stored in a counter.  (I'm using DrawCounterAsTile to display a life gauge.)  Now, it works well, but the thing is that the character can pick up some power ups that will boost his maximum health. 

So I want to set the MaxValue of the Counter at runtime, but I guess there is no "set" on that property, I get an error when I try to change the MaxValue of a counter with a custom function.  So I look around in the source code and in the reference guide but I couldn't find where the Counter class is written.  Where is it?  Is there a specific reason why the MaxValue of a counter shouldn't be changed at runtime?

Is there a better way to accomplish this?

Thanks!  :)

I think the best option in your case would be to have the counter's max be the absolute max, including any powerups. Then have another counter that represents the current max health. The counters are all generated code, stored in a single file (counter.cs?). They aren't anywhere in the source code tree.

You could try adding a file "CustomCounter.cs" to your project containing this code:

Code: [Select]

public partial class Counter
{
   public int WritableMaxValue
   {
      get
      {
         return this.m_nMax;
      }
      set
      {
         this.m_nMax = value;
      }
   }
}

Then you should be able to update WritableMaxValue (just like you were trying to update MaxValue) but this time it'll work.

Wow these partial classes really are magic :).

Cool!  Thanks guys, I'll take a look into this tonight. :)

Hey, the partial class works great!

 I had to remove the namespace in the custom code, but otherwise, it works like a charm!  Thanks a lot! :D
