Group Help

[I-IntegraL]

please help me fix the error. I do not understand what is wrong.
I have a function that takes data. (function grouping takes integer i returns nothing) But I don’t know how to transfer it there correctly

ForGroup runs in a separate function so the only way to access that data is to assign it to a global variable that you then reference in the function that’s used in the ForGroup. This is a perfectly acceptable way to do it as with proper practice there is no chance for the variable to be overwritten. Even if you don’t understand vJASS additions you can take advantage of the free declare globals blocks:

globals
  integer MyIntName = 0
endglobals

The other solution is to build your own group loop within the function. This has a side effect of removing all the units from the group when you loop through it so it’s probably not great if you want to retain the group (though you can just add them to another empty group instead).

local unit u
loop
  set u = FirstOfGroup(g)
  exitwhen u == null
  call GroupRemoveUnit(g, u)
  //do stuff with u here
endloop
