[JASS] Integer Array

[Ciebron]

How can i see if a Index in a array havnt been used for something like

DismishingReturn[H2I(Dat.u)-0x100000]

If i do like

if DismishingReturn[H2I(Dat.u)-0x100000] > 0. then

It wont work,i have tried all diffrent stuff but nothing have worked so far :/

I can detect if a unit enter the map and set a value for the unit (effective?).


Or for eg. lets say i make a local integer what value or what ever will it have

local integer I = ??

I think the default value is NaN, Not a Number. This is why:

local integer i
set i = i + 1

makes the thread crash. Comparing it as less than, greater than, or equal to anything should always return false.

So, for example, if you know that a variable at a used index may never have a value less than 0 for your purposes,

if not (DismishingReturn[H2I(Dat.u)-0x100000] > -1) then

should return true only when the index is unused. (notice the "not".)
