Malf	JASS: struct blah integer i endstruct function blarg takes nothing returns nothing local blah b1 = blah.create() local blah b2 = blah.allocate() endfunction I'd just like to kindly ask what is the difference between .create() and .allocate() ?

you can create a custom create method, there you have to you .allocate() to get a fresh new struct.

JASS:

struct blah
    integer i
    static method create takes integer i returns blah
        local blah b = blah.allocate()
        set b.i = i
        return b
    endmethod
endstruct

function blarg takes nothing returns nothing
    local blah b1 = blah.create(5)
endfunction

Malf	Oh I see, but what's the difference between them?

allocate is private and can be used only inside struct methods.
create is public and if there is no one it will be automatically created.

allocate is dynamic method.
create is static method. -- ups error, they are both static

You can also exend create to give it your custom arguments,
allocate cannot be changed.

Allocate should be only used inside custom create method.
The fact that you can do this: (use allocate outside of struct method)

JASS:

function blarg takes nothing returns nothing
local blah b1 = blah.create()
local blah b2 = blah.allocate()
endfunction

..is something I consider a design error in jasshelper

Malf	Oh I see, thank you then cohadar. Repped of course.

Vexorian	allocate is private and it has always been private, thus the function in your first post is impossible to make. Edit: If you don't declare an static create method, then jasshelper makes one automatically for you, that just calls allocate() and is public. That's the difference.
