Instance members

So, you can declare struct members of any type, even struct types. You cannot however declare array members, this limitation should be removed in later versions.

struct pairpair
    pair x=0 //you cannot use pair.create() and should actually only use constants for default initial values.
    pair y=0
endstruct

function testpairs takes nothing returns nothing
    local pairpair A=pairpair.create()
    local pair x

    set A.x=pair.create()
    set A.y=pair.create()

    set x=A.y //notice we are saving A.y in a backup variable so we can destroy it.
    set A.y= pair_sum(A.x,A.y) //this replaces A.y that's the reason we saved it

    call BJDebugMsg(I2S(  A.y.x )+" : "+I2S( A.y.y )) //notice the nesting of the . operator

    call A.x.destroy()
    call A.y.destroy()
    call A.destroy()
    call x.destroy()
endfunction
