A little MP system help, I think... Options

[Davimus]

Hello, I'm trying to figure a way to make a resource start at zero and then build up from damage attacks (you know mmo rage stuff). and by "figure out" I mean scanning these forums because I have no idea what I'm doing when it comes to script other than what other people tell me xD.

So just to clearly state what I'm asking is: I already have a replacement MP system all I need is someone to tell me/show me/give me something that will allow a resource to start at zero and build up each fight, because that would be wonderful.

Also, not to drag on, but could this "thing" I would need to do also allow me to make a resource start at max every fight?

Thank you very much in advance anyone that decides to help me .
