Solved Calculate damage using protection

I will make a plugin that will increase the damage received from the player, but I want the calculated saje damage according to the armor, potions, etc., tried to find the code in bukkit that does this, but I found, algue could help me with that?

Sorry for English, I do not speak English.

Amount the armour protects

http://minecraft.gamepedia.com/Potion
The damage that should be applied when attacking (when attack has strength)

 

I had already found these links, but in the case of customized armor (mods etc) would have no way to calculate, would bukkit on how to get the Defense points or manually calculate not affect these things?

 

Mods are not supported by bukkit.

If you want to add something that is not part of the base game, that would require manual calculations.

 

Thanks
