How do I create a simple health bar on the gui editor that corresponds to the current characters health points.

And how do I give each character their own stats instead of having it global.

I recommend buying the RPG2 source code. for me it was well worth it. there is code in there that will show you how to do that. As for designing the gui healthbar, the most fun way is to just dive right in into the gui editor and try to make something that looks cool.
