Leaks GUI/Jass

[ZiBitheWand3r3r]

Hello, I know theres much about leaks on Hive but Im not sure about this:

• DropItems
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to DropAllItems
  • Actions
    • Set TargetPoint = (Position of (Triggering unit))
    • -------- --------
    • For each (Integer TempIntegerA) from 1 to 6, do (Actions)
      • Loop - Actions
        • Hero - Drop the item from slot TempIntegerA of (Triggering unit)
    • -------- --------
    • Custom script: call RemoveLocation(udg_TargetPoint)
    • -------- --------
    • -------- should I use this 'null' here or not ? --------
    • Custom script: set udg_TargetPoint = null

The question is about last line. Var is global.
---
Second question is:

function IsUnitAlive takes unit u returns boolean
  return not (GetUnitTypeId(u) == 0 or IsUnitType(u, UNIT_TYPE_DEAD))
endfunction

Unit 'u' is not declared as local, but used in GUI triggers, so should I use
set u = null
at the end of function or not?

For user defined global (udg_ prefix variables) do not need to null them since they will get reuse/recycle. You will only need to null variables that are created locally
