"Invalid escape character sequence" is ?

[Komaqtion]

Hi!
I was just wondering what this sentence means?
I get that error in this line in my attempt at starting to work with JASS:

local string e = "Abilities\Spells\NightElf\Taunt\TauntCaster.mdl"

What am I doing wrong ?

PS: Does any1 know how come i can't use CODE wrapping or any of those things, because it just don't seem to work. I can't even click those icons when im writing a reply... and I can either use the Quick reply button to reply to posts. i have 2 use the Quote button to be able to write posts

local string e = "Abilities\Spells\NightElf\Taunt\TauntCaster.mdl"

Should be

local string e = "Abilities\\Spells\\NightElf\\Taunt\\TauntCaster.mdl"

You must have double \ in the JASS strings if you're refering to "\".

Think of the first one as a "start" for the escape character sequence, the second one is the actual character you're using (break line would be \n for example instead of |n).

 

[Komaqtion]

local string e = "Abilities\Spells\NightElf\Taunt\TauntCaster.mdl"

Should be

local string e = "Abilities\\Spells\\NightElf\\Taunt\\TauntCaster.mdl"

You must have double \ in the JASS strings if you're refering to "\".

Oh ok thanks you sooo much!!

 

[Komaqtion]

Ok but now i got an other error that i don't know what it means:
"Local declaration after first statement"

It refferes to these lines:

"loop
local integer i = 1
exitwhen i==4 <-- This one
local string e = "Abilities\\Spells\\Human\\Flare\\FlareCaster.mdl"
local location loc = GetUnitLoc(GetTriggerUnit()) <-- This one
local location loco = OffsetLocation(loc,i*2,i*2) <-- This one
endloop <-- This one
endfunction"


BTW: Sorry for dubble post!!!!

 

[SFilip]

Locals must be the first thing defined in a function.

local integer i = 1
loop
exitwhen i==4
local string e = "Abilities\\Spells\\Human\\Flare\\FlareCaster.mdl"
local location loc = GetUnitLoc(GetTriggerUnit())
local location loco = OffsetLocation(loc,i*2,i*2)
endloop
endfunction

 

[Komaqtion]

Ok thanks =)

Also...is there a function that is like polar offset as in GUI ??

EDIT: Sorry found it XD

But what is the local for a special effect?

And also, is there any none BJ functions to get last created unit/special effect ???

 

[wraithseeker]

Yes, just convert it from GUI to Jass and you get it , but it is a BJ which alot people here don't really like for making code more efficent.

There is a native but I forgot which..

 

[cleeezzz]

misread
what do you mean "what is the local of a special effect?"
its a string?
if you want to avoid last create sfx, then set it as a variable. set sfx = AddSpecialEffect(blah,blah,blah) or just destroy it as you create it. call DestroyEffect(AddSpecialEfect(blah,blah,blah))

 

[Komaqtion]

but if I create a special effect and then set it to a local, why do i use DestroyEffect(AddSpecialEffect()) ???
Why not use DestroyEffect(e)
where e is the variable set for the effect ?
will this create the effect as i set it to a variable ?

This is the trigger:

function Spell_Check takes nothing returns boolean
    if ( not ( GetSpellAbilityId() == '0000' ) ) then
        return false
    endif
    return true
endfunction

function Spell takes nothing returns nothing
local location l = GetUnitLoc(GetTriggerUnit())
local string s = "Abilities\\Spells\\Human\\Flare\\FlareCaster.mdl"
call AddSpecialEffectLoc(s,l)
call DestroyEffect(GetLastCreatedEffectBJ())
call RemoveLocation(l)
set s = null
endfunction

function Effects takes nothing returns nothing
local integer i = 1
local string e = "Abilities\\Spells\\Human\\Flare\\FlareCaster.mdl"
local location loc = GetUnitLoc(GetTriggerUnit())
local location loco = PolarProjectionBJ(loc,200.,i*90)
loop
exitwhen i==4
call AddSpecialEffectLoc(e,loco)
call DestroyEffect(GetLastCreatedEffectBJ())
call RemoveLocation(loc)
call RemoveLocation(loco)
set e = null
endloop
endfunction

//===========================================================================
function InitTrig_Untitled_Trigger_006 takes nothing returns nothing
    set gg_trg_Untitled_Trigger_006 = CreateTrigger()
    call TriggerAddCondition(gg_trg_Untitled_Trigger_006,Condition(function Spell_Check))
    call TriggerRegisterAnyUnitEventBJ(gg_trg_Untitled_Trigger_006,EVENT_PLAYER_UNIT_SPELL_EFFECT)
    call TriggerAddAction(gg_trg_Untitled_Trigger_006,function Spell)
endfunction

 

[SFilip]

There is no point in having the effect variable if you're just going to destroy it right away.
And strings don't have to be nulled, but locations do.
And you probably don't want to use GetLastCreatedEffectBJ (or any GetLastWhatever) in Jass.
And your condition can be simplified like this:

function Spell_Check takes nothing returns boolean
    return (GetSpellAbilityId() == '0000')
endfunction

 

[Komaqtion]

Then how am i supposed to destroy them??? (the effects i mean XD)
And am i supposed to remove the location first and then null it or what ?

 

[Larcenist]

call DestroyEffect(AddSpecialEffectLoc("Abilities\\Spells\\Human\\Flare\\FlareCaster.mdl",loco))

A nifty little trick to get used to if you want to code in JASS.

 

[Komaqtion]

And as i asked before =), does this create the effect right also and then destroy it ?

 

[T.s.e]

Yes. But not all effects are displayed, only those who have no animation names. Such as Thunder Clap, War Stomp, Taunt, Howl of Terror, etc.

 

[Komaqtion]

yeah those that lika only play once or so =) ... thanks sooo much for this =)


EDIT: Then can you do this too?:

set u = (CreateUnitAtLoc(Player(0),i,l,bj_UNIT_FACING))

 

[Charapanga]

Anything that returns something can be used to set the type variable the function returns, be it global, be it local, be it array...

 

[Komaqtion]

ok thanks ... this makes it alot easier

 

[Charapanga]

yeah, you'll have to get used to use only as much lines as you need, and its much easier...example:

local unit u = CrateUnit(p, u, x, y, f)

is much better than

local unit u
call CreateUnit(p, u, x, y, f)
set u = GetLastCreatedUnit()

 

[T.s.e]

Not to mention that the above function won't work, since the native CreateUnit doesn't set bj_lastCreatedUnit, while the BJ-version does.

 

[Komaqtion]

So I'm just wondering, are these triggers quite efficient now then ?

function Spell_Check takes nothing returns boolean
    return (GetSpellAbilityId() == '0000')
endfunction

function Spell takes nothing returns nothing
    local location l = GetUnitLoc(GetTriggerUnit())
    local string s = "Abilities\\Spells\\Human\\Flare\\FlareCaster.mdl"
    call DestroyEffect(AddSpecialEffectLoc(s,l))
    call RemoveLocation(l)
    set l = null
endfunction

function Effects takes nothing returns nothing
local integer i = 1
local string e = "Abilities\\Spells\\Human\\Flare\\FlareCaster.mdl"
local location loc = GetUnitLoc(GetTriggerUnit())
local location loco
loop
exitwhen i==4
set loco = PolarProjectionBJ(loc,200.,i*90)
call DestroyEffect(AddSpecialEffectLoc(e,loco))
call RemoveLocation(loc)
call RemoveLocation(loco)
set i = i+1
endloop
set i = 0
endfunction

//===========================================================================
function InitTrig_Untitled_Trigger_006 takes nothing returns nothing
    set gg_trg_Untitled_Trigger_006 = CreateTrigger()
    call TriggerAddCondition(gg_trg_Untitled_Trigger_006,Condition(function Spell_Check))
    call TriggerRegisterAnyUnitEventBJ(gg_trg_Untitled_Trigger_006,EVENT_PLAYER_UNIT_SPELL_EFFECT)
    call TriggerAddAction(gg_trg_Untitled_Trigger_006,function Spell)
endfunction

function Trig_Untitled_Trigger_006_Actions takes nothing returns nothing
local string e = "Abilities\\Spells\\NightElf\\Taunt\\TauntCaster.mdl"
local integer i = ('Hpal')
local location l = (GetRectCenter(GetPlayableMapRect()))
local unit u = (CreateUnitAtLoc(Player(0),i,l,bj_UNIT_FACING)) 
call PanCameraTo((GetLocationX(l)),(GetLocationY(l)))
call RemoveLocation (l)
call TriggerSleepAction(5.)
set l = GetUnitLoc(u)
call DestroyEffect(AddSpecialEffectLoc(e,l))
call RemoveLocation (l)
set l = null
set i = 0
set u = null
endfunction
//===========================================================================
function InitTrig_UntitledTrigger006 takes nothing returns nothing
    set gg_trg_UntitledTrigger006 = CreateTrigger()
    call TriggerRegisterTimerEventSingle(gg_trg_UntitledTrigger006, 1.0)
    call TriggerAddAction( gg_trg_UntitledTrigger006, function Trig_Untitled_Trigger_006_Actions )
endfunction

EDIT: But how do i pan the camera for only player red, without BJ:s ?
