Make spells and attacks that effect 3 bars?

So when you make a Token, you know how they each have those three bars, where you can add health, mana, armor, whatever How do I make macros that specifically effect those? So when I launch a fireball, it does damage, and shows it in the bar? I'm not using any specific character sheet, because i'm making a homebrew game. Would it not be possible unless I either go pro or use a pre made sheet?

The only way to do that is with the API, a Pro Subscriber Perk.  Specifically, you need to be in a game where the game's creator is a currently active Pro Subscriber.  Once you are, there are quite a few scripts for doing this.  TokenMod and GroupCheck being the predominant ones.

Adding to Aarons post to be absolutely clear: this isnt an issue of homebrew or pre-made sheets. Macros can only display information, they cant change any values anywhere. A macro can read  attribute values to use in rolls, but you can't change  token bars, attribute values on a sheet, or anything else with a basic macro.  With a Pro subscription, you can use API scripts which can change these things, but basic macros can't do that.
