Handle Vars and GroupEnumUnitsInRangeOfLoc

12-10-2007, 08:34 PM

First: I have a timer which uses handles to pass a location to an evaluative function, but when I use the following code:

JASS:

local timer t = GetExpiredTimer()
local location l = GetHandleHandle(t, "l")

I get a compile error that says "Cannot convert handle to location", but I've checked through the GetHandleSomething functions, and there is no "GetHandleLocation" :(

Second: Part of that same function needs to group enemy units from around a location, so I have the following code:

JASS:

call GroupEnumUnitsInRangeOfLoc( g, l, 400, Condition(function Ensnare_EnemyUnit))

Ensnare_EnemyUnit is:

JASS:

return ( IsUnitEnemy(GetTriggerUnit(), Player(0)) == true )

I need to replace "GetTriggerUnit()" with something...what? and I need to replace "Player(0)" with "GetOwningPlayer(GetSpellAbilityUnit())" but that won't work since the Ensnare_EnemyUnit isn't within the scope of GetSpellAbilityUnit()
Any help?

Av3n	Make an GetHandleLocation then just CnP GetHandleHandle rename it to GetHandleLocation and make sure it returns location + even though locations are handles... handles aren't locations -Av3n

moyack	Hmm... it seems you are using an incomplete Kattana's HandleVars, then you should create this function: JASS: function GetHandleLocation takes handle subject, string name returns location return GetStoredInteger(LocalVars(), I2S(H2I(subject)), name) return null endfunction For the second question: you must use GetFilterUnit() command EDIT: Av3n won me :P

WNxCryptic	Wait, so what does GetFilterUnit() reference, exactly? Does it reference the unit from the group to check the condition against, or does it check the original, casting unit?

HINDYhat	It's the equivalent of 'Matching Unit' in the GUI.

WNxCryptic	So is there anyway to reference the casting unit?

return ( IsUnitEnemy(GetTriggerUnit(), Player(0)) == true )
For your needs... Well you'll want to set up this up before grouping your units

JASS:

set bj_groupEnumOwningPlayer = GetOwningPlayer(GetSpellAbilityUnit)
set bj_ghoul[100] = GetSpellAbilityUnit

then you cond ahould be like this: return ( IsUnitEnemy(GetFilterUnit(), bj_groupEnumOwningPlayer) == true )
Now to reference to the casting unit... You'll have to code your group function(First of Group, ForGroup etc.) to check if bj_ghoul[100] is your casting unit.

This isn't a good way to do it... Well it is for me. Learn how to abuse Blizzard.j globals
