Calling internal gta functions from the "outside"

[monday]

hi, is there any simple way of calling functions like:

typedef bool (__cdecl *WorldCoords2ScreenCoords_t)(myVector*, myVector*, float * , float * , char, char);
WorldCoords2ScreenCoords_t WorldCoords2ScreenCoords = (WorldCoords2ScreenCoords_t)0x70CE30;
WorldCoords2ScreenCoords(&inPoint, &outPoint, &x, &y, 0, 0);

but by using Read/WriteProcessMemory? Or any other not complicated way?

I think that would help we were discussing it over there.
