USAGE NOTES


HPPercent(id)
SPPercent(id)
Returns the current hp or sp of id as a percentage. This only works on things which the player can see the hp/sp of, obviously.

Closer(id,x,y)
Returns coordinants of a location 1 cell closer to actor (id)

ClosestR(id1,id2,range)
Returns coordinants of the cell within <range> cells of <id2> that is closest to <id1>.
Intended for targeting of ranged skills.

BetterMoveToOwner(mercid,range)
Moves to the closest sell withing range cells of the owner.

IsNotKS(id)
Returns 1 if attacking monster (id) would be a KS, 0 otherwise.

IsFriend(id)
Returns 1 if (id) is the owner or a friend.

@@@@@@@@@@@@@@@@@@@@@@@@@
@@@ Monster Functions @@@
@@@@@@@@@@@@@@@@@@@@@@@@@

GetMobCount(id,range,[id2])
Returns the number of monsters within range cells of the actor id, and the number of said monsters which are currently targeting id. If id2 is specified, monsters which are targeting id2 will also be included in the second value returned.
Useful for deciding whether to use anti-mob skills.
ex:
local mobcount,aggrocount = GetMobCount(MyID,1,GetV(V_OWNER,MyID))

GetBestBrandishTarget(id)
Returns the id of the best monster adjacent to the mercenary to use brandish spear on (that is, the target that will result in the most monsters being hit).
Assumes level 1 brandish area.

ex:
SkillObject(MyID,MySkillLevel,ML_BRANDISH,GetBestBrandishTarget(MyID))


@@@@@@@@@@@@@@@@@@@@@@@
@@@ Skill Functions @@@
@@@@@@@@@@@@@@@@@@@@@@@

GetAtkSkill(id)
Returns a list containing skill id, skill level of the mercenary's single target offencive skill. Crash is not returned in this list, because the damage output spamming crash is lower than the damage output from using normal attacks.

ex:
local skill,level= GetAtkSkill(MyID)

GetMobSkill(merctype)
As GetAtkSkill() only for antimob skills

ex
local skill,level = GetMobSkill(MyID)

GetQuickenSkill(id)
Returns a list containing the ID of the weapon quicken skill posessed by the mercenary and the skill level

ex
local skill,level = GetQuickenSkill(MyID)

GetGuardSkill(id)
As GetQuickenSkill() only returns the ID of the guard or parry skill posessed by the mercenary.

GetSacrificeSkill(id)
As GetQuickenSkill() only returns the ID and other perameters for the Sacrifice (aka Devotion) skill posessed by the mercenary.

GetProvokeSkill(id)
As GetQuiceknSkill() only returns the ID and other perameters for the Provoke skill posessed by the mercenary.

GetPushbackSkill(id)
As GetMobSkill() only returns the ID and other perameters for the pushback skill (arrow repel or skid trap) posessed by the mercenary
