[JASS] Weird JASS function error

[lolreported]

Hello, I'm currently creating a function that should store variables into a DPS system... But I've encountered a weird error, I don't know why it's appearing...

This is the function:

function SetDPS takes unit uc, unit ud, real dmg, real dur, string effectpos, string speffect returns nothing

endfunction

and this is how I call it:

• Cast
  • Events
  • Conditions
  • Actions
    • Custom script: call SetDPS(udg_DT_Caster[udg_DT_Index[3]], udg_u[0], udg_DT_DPS[udg_DT_Index[3]], 2.0, "overhead", "Abilities\Weapons\PoisonSting\PoisonStingTarget.mdl")

(Don't care about the "udg_DT" variables and such, it's just a test)

but this will give me this error:

• Expected expression
• Expected a function name

but when I remove "Abilities\Weapons\PoisonSting\PoisonStingTarget.mdl" it won't give me any error... Seriosly, whats wrong?

It's something every jasser must learn, don't worry :
when you have a string, you must replace each slash (\) you got by a double slash (\\).
I don't really know the reason of this but in several programming language, the \ is used as a meta-character and has a specific fonction (though I don't know its use in jass).

Okey, I'll try if it works and tell you in a few seconds if it works!

Edit: It worked! Thanks! +rep

While you're on the topic of strings and slashes, you can do:

local string s = "\""

This will be a string that is filled with nothing but ". The back-slash characters yield a special character right after them, so if you've just got one "\" then it won't necessarily mean it is a back-slash, but if you've got two then the processor/compiler can ensure it is always a back-slash.

Okey, then I understand a little more thanks!

It is also useful information if you want to put quotation marks in your strings.

local string msg = "\"Hello, sir?\""

This yields:

"Hello, sir?"
