How MAB models the body and damage

8/2/2018

Let me teach you the secrets of Kung-Fu

Martial Arts Brutality has been out for sometime now and a lot of higher level players are interested to know how the game models the body so they can better craft their decks and tactics. So here I'll go into a lot of detail about the internal model that the game uses. I'll also show the actual data from the game.

So here we go...

Body Part Data

Each body part has different levels of hit points. And each body part maybe protected by other parts. Each body part also contributes towards different KO types.

Let me explain that in detail. Here's the first two lines of the body part data file:

;      Type               Region   Class       HP       Failure%   Protected
BZ   Skull               Head   Bone       500       20.0%       None
BZ   Brain               Head   Organ       1200   100.0%       Skull           65.0%   None

BZ is Body Zone. Type is the body part type. Region and class are self evident.

HP is the number of hit points. When this reaches 0 the part is dead.

Failure % is the amount that part contributes to any particular KO, more on that later.

Protected shows if this part is protected and by how much. Here we can see the Brain is protected by the Skull at 65%. So 65% of the damage to a Brain hit is taken by the Skull. (So it's more efficient to take out the Skull and then the Brain)

Here is the full list

;      Type               Region   Class       HP       Failure%   Protected
BZ   Skull               Head   Bone       500       20.0%       None

Important note: The final HP of each part is further modified by the Fight Style you use and your current Performance settings. For example, Wing Chun uses have very weak bones, at -50%, so all the Bone HP values will be 50% lower.

A full break down of fight style modifiers can been seen here.

KO Types

To gain a KO you need to destroy a certain set of body parts. The following data show each KO type and the body parts that belong to the KO type.

Remember the 'Failure %' from the table above? Well that's the amount that part contributes to the KO. So if the Brain is 100%, you'll get a KO with just that part destroyed.

However, the Nose is 20%, so if you break the Nose you'll have 20% of a Head KO.

Additional to that there's the 'BreakAtLeast' value which shows the minimum number of parts that must be destroyed to get a KO. (Even if the total Failure % is > 100)

So, you must 'BreakAtLeast' x parts and the sum of the 'Failure %' of those parts must be >= 100% to get a particular KO.

Speed and Power

Each card has a Speed and Power value. These are typically in the range from 1 - 10, but can be boosted higher. These values are modified and scaled to get final amounts for an attack.

Power works in the following way:
Power 1 = 75 hit points
Power 10 = 180 hit points

So Power is linearly interpolated from 75 to 180. Power over 10 will be interpolated at the same rate.

The interpolated Hit Point value is then deducted from the HP value of the body part that's hit.
(Power value is also affects by your swipe rating, Chi Boosts and Performance Point settings)

Speed uses the following system. Speed is turned into a time. This time determines how long it takes the attack limb to travel across it path in the defend turn.

Speed 1   = 0.75s
Speed 10 = 0.40s

So for speed 1 you have 0.75 seconds to block.
At Speed 10 you have 0.4 seconds to block.

Speeds above 10 are similarly calculated.

Summary
I hope that all makes sense, it's pretty dense, but it's what was needed to build a reasonably interesting model of the body.
I hope it helps you build better decks and may you go on to triumph against your foes!

Use this knowledge wisely.

Very well described. So I should stop randomly attacking the knee, the hand and the brain hahaahaha

Ah yes, that's not the best strategy!

John Evans

Okay, but what happens if you attack a body part that's already broken?

9/2/2018 08:18:11

Nothing. Striking a broken body part will have no effect.
(Other then to cause that card to be replaced next deal)

Very interesting informations, I can see how much you could go a wrong way without all this ...
One question still : when you say "Here we can see the Brain is protected by the Skull at 65%. So 65% of the damage to a Brain hit is taken by the Skull." : so if I make a hit on a brain without having destroyed the skull before, does that mean that ONLY the skull is hit (by 65 %), or that both the skull AND the brain are hit (respectively by 65% and 35%) ?

13/2/2018 08:57:07

The latter one, the skull is hit with 65% and the brain is hit at 35%.

So on the small chance that you get a KO, which is not listed on the table for example, Catastrophic Leg Trauma, has a 5% to occur if I destroyed the foot, is this thought process correct?

13/2/2018 08:58:39

Nope, the 5% isn't the % chance of a KO, it's the % that part contributes to a KO.
So if you break the foot at 5% you need a further 95% to get the KO.

thank you for publishing in-depth info like this -- keep it up! knowing the underlying game mechanics is essential and PRICELESS for higher level players who love to min-max.

13/2/2018 08:58:56

Thanks!

After seeing many many moves taking more than 4-5 seconds to travel across the screen (followed by an attack which literally hits in an eyeblink) and seeing opponents blocking every single high speed attack (speed 20+) combined with several chi-support cards which are supposed to make blocking more difficult i wonder how that was possible

I came up with two things:

#1
attack speed is calculated linearly (i really hope this is wrong, because given the data above the max attack speed would be 20 with 0.011 seconds travel time and evrything above 20 would be negative time ..

#2 PC player just use ESC to block attacks to freeze the screen at the start of any attack to prepare the block ( pretty easy to block any attack this way )... can't tell for other platforms

So, can you tell us something about the speed calculation?
Don't get me wrong, the game is pretty cool until you reach a certain level or get opponents using glitches

20/2/2018 08:51:41

Past 20 additional speed is limited in a non-linear way. As you say, you can't keep interpolating in the same way.
Thanks for the heads up on the 'esc' ploy. I'll fix that.

Game been out for awhile? it just only came out on steam tho.. I hope you expand the game further especially the pc version. You got a HIT here. Can add diff character models, ala Street Fighter and tons of other potential of this game still

20/2/2018 08:52:46

I'm planning on adding more features and content as time goes by. Being a 1 man team means it can take a bit of time though.

20/2/2018 14:43:59

Heres an idea, how about special mortality animations ala Mortal Kombat and special combo moves etc.... I see you are working on Beat Hazard 2, but I hope you attention back to this game and maybe expand your team.

Just to give you an idea, I'm a hearthstone player who has spent a lot of money on that game and I'd rather play MAB tbh , having way more fun
