MQ2Melee also has 3 global (not character specific) parameters that can be set in a second, optional INI file. MQ2Melee uses default values for these parameters unless it finds a file named MQ2Melee.ini that you created in the same directory. Here is an example of a MQ2Melee.ini file and a description of the parameters:
[Settings]
SpawnType=10
MeleeKeys=z
RangeKeys=x
SpawnType: This is the allowed spawn 'types' that mq2melee will be allowed to engage. Add together the desired target types, the total is put in this parameter. (1 = PC) (2 = NPC) (4 = PC PET) (8 = NPC PET) (16 = PC CORPSE) (32 = NPC CORPSE). Default is 10 (2 for NPC + 8 for NPC PET = 10).
MeleeKeys: Melee Attack Key (not same as eq attack key, or it will cause problems). Default is z.
RangeKeys: Range Attack Key. Default is x.
