RPG Upgrade System Help

[Zeppelin]

Ok well I'm making an RPG for my ISP and I'm incuding an Upgrade system. The way it works is that you buy upgrades for you character using upograde points (Which are basicly points you use to add the upgrades to your character so the more you have the more you can upgrade). Now I have the upgrade buying part down but I need help with the acctual attacks during battle. Since the game also has graphics I need to use Draw.Text to display the attacks. Now what would be the best way of making the special attacks appear on screen and have the player use them?

I'm thinking of using boolean opperators so if a sectain upgrade is true it'll display it on screen and allow the player to use it. Would that work or is there an easier way?

Ok, there is a little bit of confusion...

- you can buy upgrades using points.
- upgrades add different attacks? or upgrades as in strength, agility, magic etc...?

Anyhow, to answer your question... Basically if you want them to click to use special attack (as in you upgrade and get a special attack that you can use), then you have a boolean which determines if something is drawn to screen. However, there is other ways in which you may want to approach this. It is purely up to you... for instance you may want the letter 'q' to be one special attack, and the letter 'y' to be another... it is personally up to you what you want to do. Just remember to keep the user in mind, and the comfort of the user (who will be using/playing the game). Also if you use letters you may want to draw on screen like the possible allowed characters to be pressed etc...
