[JASS] Integer Question

[Deep Sea Kraken]

Do integers leak if you dont set them to null, because i have: x = null (x is a local var) and it keeps giving me an error message

integers do not leak. and if u really did type that, than u might have missed "set x = null"

Bottom line, integers don't leak. You may expect that as I did, but they don't leak, nor do reals. Nulling integers and reals cause problems and say that there is an error. Remember that only certain types of variables need to be nulled, which excludes the integers and reals.
@V_V_V: You can't null integers and reals...

I hope this helps. :emote_grin:

i dont really think you should NULL a integer use
set VARIABLE =

and its done

Only handle-type variables leak. Non-handle types are:
Reals, integers, strings, booleans, umm what else?... :S
If you want to "null" them at all costs you can do it by:
set real = 0
set integer = 0
set string = ""
set boolean = false

But as i said, there's no need to do so.

null is actually a constant handle value of NOTHING if you want to look at it that way.

Setting non handle based vars to null is impossiable since it is like trying to set.

local intiger i = "DrSuperGood"

Which will ofcourse return an error. Vexorian is about the best jass programer that WC3 has seen and he never set his local non-handles to "nothing" which means that they do not leak.

 

[PurplePoot]

same with

set i =

That'll just make the compiler go OMGWTFNEEDPARAMETERNUB

Anyways, any native types [boolean,string((exception here, sort of!!)),code,integer,real] don't leak, so they don't need to be nulled or destroyed.

Also, null is of type handle (or string, another exception with strings, but strings should really be handles), so any non-handle type can't be set to null

Reals and integer variables are objects in their own right. When the variable disappears, therefore, the object disappears. Thus they cannot leak.

H2I(null) gives 0x100000 or something I think. Just a value. But you can't set real or integer variables to null.

Strings leak, but that is only when new, unique strings are created, and is unstoppable (but may be avoided).

Code variables cannot leak.

-basicly if you use string "Hi!" and put it to go every 0.01, game might lag but wont leak. But if you use Hi + random nmber between some 2 numbers, it will leak, as it has to create new unique string in memory.

 

[V_V_V]

it actually gives an error? I would've just thought doing so did nothing. Well, how would I know? theres no need to so I've never tried =/

 

[PurgeandFire]

Yup, it will say something like:
"Unexpected Statement" or "Unexpected Null" or something like that... :emote_grin:
