I'm not really having a stat problem just a way of assigning initial stats to a certain character race. I want it so each race starts with different default stats. Consider the following code(sorry if it's long):

mob
var/set player_name = null
var/set hp = null
var/set ki = null
var/set enrgy = null
var/set str = null
var/set money = null
var/set ctarg = null
var/set ctech = null
var/set tnl = null
proc/StatCheck()
if(usr == /mob/saiyan)
var/set player_name = null
var/set hp = 100
var/set ki = 20
var/set enrgy = 30
var/set str = 5
var/set money = 0
var/set ctarg = null
var/set ctech = null
var/set tnl = 100
Stat()
stat("null:", usr.icon)
stat("Name:", player_name)
stat("Health:", hp)
stat("Ki:", ki)
stat("Energy:", enrgy)
stat("Strength:", str)
stat("Speed:", spd)
stat("Zenni:", money)
stat("Current Target:", ctarg)
stat("Current Technique:", ctech)
stat("To next level:", tnl)
