[XP] Need help with event system im making, please :D

[RMXPirate 0]

So I was making a on screen battle system and was wondering what I would do to make based on the users attack etc how much he/she will take away from the monster when he/she attack it? I have the users attack hp all that set up but how do i say based on user hp which is a variable obviously it will take this much damage from the monster? Credit will be given to all who help. If you want to you can also contact me on YIM, AIM , or MSN: jdbeyer16@yahoo.com, piratejdb, pirate_ichabod@hotmail.com. Thanks, rpgmakerwhat.

I'm a little confused on what your asking.

Based on user's hp?

 

Like, if user has greater than 50% of health, do this much damage?

Or, if player has 500 damage, than do 50, or some type of formula like:

HeroHp + HeroStr - EnemyLuck - EnemyDef = Total Damage
