[Trigger] Need help with a system on this site

[Peacehagen]

I tried to copy a missile system from this site (http://www.hiveworkshop.com/forums/...-03-a-112543/?prev=search=missile&d=list&r=20)

But i got an error and I cant figure out what is wrong :/

Here are the messages:
Expected a name
set udg_MS_tempreal[2] = ParabolaZ(udg_MS_MissileH2[udg_MS_Integer[3]],udg_MS_tempreal[1],udg_MS_distance[udg_MS_Integer[3]])

Expected a name
set udg_MS_tempreal[4] = (ZFacing(udg_MS_MissileH2[udg_MS_Integer[3]],udg_MS_tempreal[1],udg_MS_distance[udg_MS_Integer[3]])+90)

(And I have checked I have all variables. Just the ParabolaZ and ZFacing I dont have, but those arnt variables in original map either.)

Uploaded a pic aswell.

Thanks for any help on this.

They are functions. Probably declared in some library (JNGP) or in the script header.

Doesnt say anything about requiring JNGP :/ where is the script header? could you maybe try to explain how I could make this work, would greatly appreciate it.

 

[Dr Super Good]

The script header is located at the root of the trigger hirachy. In the list of triggers and folders it is the element at the far top with a map icon. People often put jass script in there.
