Changing an NPC's X/Y Coordinates

[MegaMasterX90875]

I'm trying to make a script that tokenizes and sets X/Y coordinates according to tokenized results. This is what I have so far (Note: It's in GS1):

NPC Code:

---

 if (created) {

set OrigX;

set OrigY;

OrigX=this.x;

OrigY=this.y;

//This is in case it messes up.

set EditMode;

}

if (playerchats&&strequals(#c,/Editmode)) {

EditMode=1;

message EditMode On!;

sleep 2;

message ;

}

if (playerchats&&strequals(#c,/Editmode off)) {

EditMode=0;

message EditMode Off!;

sleep 2;

message ;

}

if (playerchats&&EditMode=1&&strcontains(#c,/move chair1)) {

tokenize #c;

this.x=strtofloat(#t(3));

this.y=strtofloat(#t(4));

}

if (playertouchsme&&EditMode=1) {

blockagain;

canbepushed;

canbepulled;

}

if (playertouchsme&&EditMode=0) {

dontblock;

cannotbepushed;

cannotbepulled;

player.sprite=37;

}

The /move chair1 is supposed to be like /move chair1 <NewX> <NewY>
Also, when the player chats the sprite is changed to sitting (37) even when the player is not touching the chair.
Is there a way to make this serverside and save the position of the objects?
Is this the best way to do this?
And, can I make it check to see if it's on a wall? How do I do that?
