Can Functions take Variables/Arrays?

[aple]

Like,

function ArrayExample takes Array WhichArray returns nothing

Or something like that? =o

It does not matter at all if you use an variable with array or not. You only define the type of variable as parameter.

You can't take in an array. You can input an array element, but not the array itself.

For example:

function Test takes integer i returns nothing

endufnction

globals
    integer array z
endglobals

call Test(z) // won't work
call Test(z[0]) // works

Passing an array is possible in some programming languages, e.g. Java, but not in JASS.

Also, you should post JASS questions in the Triggers & Scripts forum. Moved.

Alright, thanks for the help Purge and IceMan. =)

And thanks for moving this, I wasn't too sure where to put it.

You can however pass a struct instance with array (or not) members inside the struct.

Or a dynamic array but that's basically the same thing limited to one variable only.

Read the jasshelper documentation and check the generated jass code to understand how it works (and the limitations).

Hashtables are a good replacement for that. Or in general make a custom container type that provides the necessary functions.

Talking about hashtable, if you want a dynamic size of array, or if you could hit the struct limitations that's indeed the way to go, else dynamic arrays / struct is the way to go.

Yeah this sucks. I had to make a function taking like 8 parameters or more. Fortunately the size of the arrays was small and fixed.
