Question regards stats calculations & formulas

Recommended Posts

Hello,

 

I have been working in a project recently using UE4, and I was wondering if someone can help me with the stats calculations.

 

There are five primary attributes in our lovely game, which are "Strength, Accuracy, Spirit, Agility, and Constitution". 

 

in which,

-Strength increases the attack of melee classes.

-Agility increases Attack Speed and Dodge

-Spirit increases SP, SP Recovery Rate and healing/damage dealt from Magic Skills.
-Constitution increases HP, HP Recovery Rate and Defense.

-Accuracy increases Hit Rate and the attack of ranged classes.

 

 

The questions are,

-how much max/min attack does a single strength point add? whats the formula behind it? 

-how much attack speed & dodge do we get from adding a single point in agility? 

-etc.. you get the idea! 

 

 

Thank you!

in case your wondering at what state i am at right now, 

 

Stats are implemented & replicated for multiplayer usages, but calculations are not accurate by all means. 

 

I just need the formulas to tweak em up real quick~

I haven't touched this in a bit, but the calculated stats (max atk, hp) have different scaling per class. You can find the scalings and the final attribute calculation in AttrCalculate.lua, code like this -

Mxhp_con_rad1[JOB_TYPE_XINSHOU], Mxhp_con_rad2[JOB_TYPE_XINSHOU], Mxhp_lv_rad[JOB_TYPE_XINSHOU]	=	3	,	2	,	15							--���hp������Ӱ��ϵ��������ϵ�����ȼ�ϵ����������

		Luk_updata[JOB_TYPE_XINSHOU]		=	0.1

shows the scaling for that job and you can see the final calculations in the `ExAttrCheck` function -

 

local mxhp	= math.floor(Con(role)*3 * Mxhp_con_rad1[job] + Mxhp_con_rad2[job] * math.pow( math.floor(Con(role)*3/20 ),  2) +Lv(role) * Mxhp_lv_rad[job] + 40)	--[[�������mxhp]]--

	local mnatk	 = math.floor( 0+ Str(role) * Mnatk_str_rad1[job] + Dex(role) * Mnatk_dex_rad1[job] + Mnatk_str_rad2[job] * math.pow(math.floor( Str(role)*4/20), 2 ) + Mnatk_dex_rad2[job] * math.pow(math.floor( Dex(role)*4/20), 2 ) )											--[[�������mnatk]]--
