fasmw 1.73

Code:

struct D3DXVECTOR4
       x dd 0
       y dd 0
       z dd 0
       w dd 0
ends

vEye: World D3DXVECTOR4


movss xmm0,[vEye.z] ;fasm get error

movss xmm0,[World.z] ;fasm compiled fine

My another code used vEye.z not World.z

I want somehow defined World as vEye

Using virtual for this ?

Code:

struct D3DXVECTOR4
       x dd 0
       y dd 0
       z dd 0
       w dd 0
ends

vEye D3DXVECTOR4
virtual at vEye
World D3DXVECTOR4
end virtual


movss xmm0,[vEye.z]

movss xmm0,[World.z]

ADD:

Code:

struc assume Base*, Type& { if ~ Type eq
        virtual at Base
            . Type
            if ~ definite .Length
                label .Length at ( $ - $$ )
            end virtual
        end virtual
    else
        label . at Base
        label .Length at 0
    end if
}
struct D3DXVECTOR4
       x dd 0
       y dd 0
       z dd 0
       w dd 0
ends

World D3DXVECTOR4
vEye assume World, D3DXVECTOR4


movss xmm0,[vEye.z]

movss xmm0,[World.z]

Thanks.
This work too

Code:

struc assume Base*, Type& { if ~ Type eq
        virtual at Base
            . Type
            ;if ~ definite .Length
            ;    label .Length at ( $ - $$ )
            ;end virtual
        end virtual
    else
        label . at Base
        label .Length at 0
    end if
}

World D3DXVECTOR4
vEye assume World, D3DXVECTOR4
