Questin about : local variable and antileaks !

in my code:


......
And my question is :
Need I set local var to null after Remove or Destroy It ?
And if yes ? then one more question :D : What does extract action "RemoveLocation(point)" and "set point = null" do ? Different what ?

And what about some more local var: timer, trigger, action, condition ?

Destroying it destroys the actual object your variable is pointing to( think C++ and destroying dynamically created objects), and nulling it effectively blanks the memory, and fixes some sort of internal error and allows it to free the memory properly.

Also, please use [jass] tags not [quote] tags. Thanks.
