set point help

[Dark_coolness]

i have this trigger

Code: Select all

Set point[1] = ((Position of CastingUnit) offset by 400.00 towards ((         ) + 1.00) degrees)

but where it says nothing i want to have it say towards ((point[1])
but i cant find out how to put it in.

Well that wouldent work, since your setting point1 right there in that trigger. Lol. So basicly, you cant set it, because point1, at that time, doesnt exist. Plus, that blank spot only works with numbers...so just try a few different degrees till ya get your desired result.

You'd wanna do this instead:

Set point[0] = ((Position of (Casting unit)) offset by 400.00 towards ((Angle from (Position of (Casting unit)) to point[0]) + 1.00) degrees)

As Syre noted, the blank in what you had takes a real variable type, not a point.

K ill tell you what i am doing to make this easier. I am making a spell that makes 8 footmen offset 400
from the casting unit at the degrees 0,45,90,135,180,225,270,315, after the units are created i want then to spin around the casting unit and if possible not that important they could stay facing the casting unit.

This would be more fun in JASS.

Spoiler:

Code: Select all

globals
trigger t = null
endglobals

function cond takes nothing returns boolean
return ( GetSpellAbilityId() == 'ANfs' ) 
endfunction

function act takes nothing returns nothing
local integer ii = 0
local unit u = GetTriggerUnit()
local player p = GetOwningPlayer(GetTriggerUnit())
local location l
loop
exitwhen ii > 7
set l = PolarProjectionBJ(GetUnitLoc(u), 400.00, I2R(ii*45))
call CreateUnitAtLoc( p, 'hfoo', l, AngleBetweenPoints(l, GetUnitLoc(u))) 
set ii = ii + 1
endloop
endfunction

function main takes nothing returns nothing
local integer ii = 0
loop
exitwhen ii > 11
call TriggerRegisterPlayerUnitEvent( t, Player(ii), EVENT_PLAYER_UNIT_SPELL_FINISH, null )
set ii = ii + 1
endloop 
call TriggerAddCondition( t, Condition(function cond) )
call TriggerAddAction( t, function act )
endfunction

Tested. When you finish casting the spell, a single footman will spawn at each of the angles you specified.

Change 'ANfs' to the ability you want to have trigger it.

I'm currently working on something to have them rotate... But no promises on that being done tonight, or ever.

It'll be done by tomorrow.

EDIT: Oh, and to put that into your map... Make a new trigger called what you want it to be. Select the trigger, then select Edit->Convert To Custom Text from the top menu. Remove everything above the line of //===============, and replace it with functions cond and act from above. Below the line, put in what's in function main, and change "t" to gg_trg_x, replacing x with what you named the trigger.

Hopefully those instructions aren't too confusing. I'll make a picture if you need.

when i try to run it i get these three lines with the error "expected end of line"

Spoiler:

Code: Select all

//===========================================================================
globals
trigger gg_trg_trigger = null

but i don't know why i get the errors
also it might just be easier for you to do the triggers then just put the map as an attachment

Oh, you don't need the globals stuff... That's just 'cause I do my things in JassCraft, and I need to declare a trigger.
