Question about Unit/Point Target Spells

03-07-2010, 11:35 AM	#1
sPyRaLz	If i create a spell that allows either a unit or point target, how do i detect it in a trigger? If i do use GetSpellTargetLoc(), but target a unit, will it take the location of the unit? vice versa, if i use GetSpellTargetUnit(), but target a point, will this return a null? The main question, if i have a spell that targets both units and points, whats the correct way to detect it?

Tot	basic spell detection via EVENT_PLAYER_UNIT_SPELL_... GetSpellTargetUnit() will return null if you targeted a point -->: local unit u=GetSpellTargetUnit() if u==null then //actions when point was targeted else //actions when unit was targeted endif set u=null and don't use loactions, they're bad cuz you've to destroy and null them

DioD	GetSpellTargetX() != 0.0 then there is no way to aim on 0.0,0.0 location soo this check will pass.

TheKid	Why not (100.0, 100.0)? That point is just as impossible to aim for as (0.0, 0.0).

-->:

local unit u=GetSpellTargetUnit()
if u==null then
//actions when point was targeted
else
//actions when unit was targeted
endif
set u=null

I understand what you're saying. I forgot to mention however than i need the spell to have the same effect whether or not i target a unit or a point.

Either way, I will need to have a point at which I can calculate the spells effects from.
Be it a unit position or a direct location.

Being so, it seems inevitable that i would have to use GetSpellTargetLoc() (If the target is not a Unit), then destroy it later. Or am I mistaken? =/ Is there another way around?

Ammorth	GetSpellTargetX() GetSpellTargetY() works for both units and points.

sPyRaLz	Ah okay, that makes sense. Never knew those functions existed though.. They appear black with my Jasshelper so ive no idea if theyre natives or some special functions built into newgenworldedit. Either ways, thanks for the replies everyone. My question has been cleared. =)
