Ah~~ I worked on this so many hours..

// ==================================================
==========================
// Bandit.ai, builds bandits, human ai, and bandito.
// ==================================================
==========================
globals
player user = Player(0)
constant integer BANDIT = 'nban'
constant integer BRIGAND = 'nbav'
constant integer ASSASSIN = 'nbae'
constant integer ENFORCER = 'nbab'
constant integer ROGUE = 'nbax'
constant integer BANDIT_LORD = 'nbad'
endglobals
