CS2D 
Custom damage

Offline
Apparently, my new mod is almost finished, except for the custom damage formula.
I added a few more rules to the thing and it become a mess. If only I know for detail how CS2D damage is calculated, it would be easier.
Basically the rule is like this:
-In zombie mode if the player is a survivor:
+If attacker successfully roll a critical hit, the raw damage will double
+If attacker's weapon have bonus damage, it will add that bonus damage percentage to his raw damage
+If attacker's status effect include another bonus damage, it will also added as above
+If victim is not a zombie, he/she will have an armor value from 0% to 95%. But on top of that is the Kevlar layer. Whenever they get hit, the Kevlar took normal damage, and the armor value will absorb the remain damage penetrated the Kevlar.
+Zombie have no such skill so they don't get bonus damage or damage reduction except the damage taken reduction they get form server setting. But they still have to take extra damage form survivor attacker's skill/stats effects.
-Thing I have to consider:
+How the extra raw damage should be added?
+What should be implemented if victim is wearing Kevlar?
+What should be implemented if victim is wearing special armor?
+What should be implemented if victim is a zombie?
+What should be implemented if victim is not a zombie?
If I can't solve all of this in a week. I will properly have to scrap the idea of extra damage and add something else to the content.
So far the formula works when zombie attack survivor. However, in the reverse case, the zombie take no noticeable damage.
I haven't tested what happen when survivor attack survivor though.
Here's my code for the damage application - sorry for the long and boring text, if you don't feel like reading it, please help me learn the damage formular:
