How to calculate damage with armor

In this I will show you guys how to calculate the amount of damage done with each weapon, with all types of armor.
Here, I have the stats for all FpsHG weaponry.
https://www.brawl.com/wiki/guns-fpshg/
Basically, according to the wiki, a gun's damage is out of 100. So if it does 50 damage, it would do 10 hp or 5 hearts in Minecraft terms.
However, using this, you can easily calculate the amount of damage each weapon does, including armor and headshot multipliers.

All weapon damage stats are without armor. So to calculate damage with armor....
First, you need to determine the amount of defense points a player has.
Just look at this guide, from here.

For example, a player with full leather would have 7 defense points, or 3.5 armor.

Now, each defense point (or 1/2 armor) reduces damage by 4%. So we can do some simple math here.
I will use the M4A1 as an example. It does 30 damage. In other words, it does 6 hp, or 3 hearts of damage to an unarmored target.
Now, if the target had full leather, he would have 7 defense points. So you can do 7*4, which equals 28. This shows the total percentage of damage reduction.
Here's an equation:
4x = z
x = Number of defense points
z = Percentage of damage reduction
Now, you can find the damage by doing y * z.
y = Damage
Remember to make z a decimal, as it is a percentage, not a whole number.
So for example, it would be 30 * .28 for the M4A1.
This gets you 8.4. Now do y - r to find the final damage.
r = Reduction in damage
So here, I would do 30 - 8.4, which is 21.6.
That means the M4A1 does 21.6 damage (aka 2.16 hearts or 4.32 hp) to a target with full leather.
Implementing multipliers is extremely easy. The only multiplier is the headshot multiplier, which is 2x for all weapons. So multiply y by 2, if you want to calculate headshot damage.

If you want damage reduction percentages for each tier of armor, here you go:
Full leather: 28%
Full gold: 44%
Full chain: 48%
Full iron: 60%
Full diamond: 80%


This may seem difficult but it really isn't that hard. Post below with any questions, comments, concerns. Have fun with this.

This also applies to MC-War and MC-WarZ (WarZ's wiki doesn't have exact damage values yet). However, Minestrike uses special multipliers, so you cannot calculate headshot damage of Minestrike weapons. (and Minestrike's wiki doesn't show exact damage values yet either.)

EDIT: The other multiplier is the @King_Daan multiplier. Any bullets that hit him will do 420x their normal damage. In other words, he's screwedddddd

 

It doesn't even require writing equations :v

 

I know, just useful information so that you can calculate damage, you know?

 

And then, the multiplier will be removed, which means you wasted all that time for nothing. :3

 

They do more damage than you think.
The Barrett does 15 hearts of damage, and does 30 with a headshot. No one can legitimately survive a Barrett headshot in other words. Not unless they used a god apple or something.
The SMGs have less recoil.
...yeah, that's it.

 

The Barrett has always been like this.
Both in WarZ, and here.
It is actually very effective. Just do a SPAS-12 + Barrett combo in WarZ, or a Model 1887 + Barrett combo in FpsHG.
@nicolecacola already knows how effective the Barrett is, especially in combos. Go ask him.
Remember, the Barrett is usually followed by a shotgun/automatic, or is preceded by those.
It does do plenty of damage to diamond, when you think about it. However, people can just spam food to overcome that. That's what breaks WarZ and FpsHG.

 

Well, you can suggest a buff if you want to.
Anyhow, you just helped me find an error on the wiki. Thanks :v
