[HELP] Player movement..

Hi all elitepvpers people, i'm Lupetto.
i need help about pg movement..
i have found this addresses,

#define ADR_MOVEMENT 0x007E5628
#define OFS_BASEM 0xC
#define OFS_MOVE_X 0x640
#define OFS_MOVE_Y 0x644

if i want go to a specific position (X,Y) i have to change
ADR_MOVEMENT + OFS_BASEM + OFS_MOVE_X = X
ADR_MOVEMENT + OFS_BASEM + OFS_MOVE_Y = Y
and freeze the value..
then click on somewhere and player start walking to (X,Y)

i think this is a really bad way to do this, i think there is a better way to do pg movement.. can anyone help me?
Thx ;)

Sorry my bad english,
Lup.
