[LUA] Error while trying to return a Lua-Value

[Stormchasing]

Hi,

i've a little problem.
While i test to fix a rangebug in one of the CCs i'm modifing i get this error

System.NullReferenceException: Object reference not set to an instance of an object.
at Styx.WoWInternals.Lua.GetReturnVal[T](String lua, UInt32 retVal)

The Code is:

isInRange = (Lua.GetReturnVal<int>(String.Format("return IsSpellInRange(\"{0}\",target)",spell.Name), 0) == 1);

And i can't figure out the problem.
The Toon has a target to check the cast, the spell is right too, but it throws an error.
Printing the result in the wow client with, does work well

/script print(IsSpellInRange("Shadow Bolt",target)); // replace the spell with something u r able to use

And NO, it is not an option to try the built-in property distance from the wowunit, this returns no useable values (Ultraxion, Madness of Deathwing, Warlord Zon'Ozz hardmode)

why are you using lua? SpellManger.CanCast includes range checks and its much faster and safer then using lua.

same for cancast ... both returns wrong values in this fights

As far as i know, then you need to have "target" (or in HB \"target\") - works for me

are u sure this has to be escaped?
okay this could explain it, it shouldn't do any difference if i use target or unit in this case, i'll try that.
Thank u


---- edit ---
thank u very much, this does the trick
now i'll test it this evening on the encounters where i had the range problems
