Snake? Array questions and more...

[Gohan43331]

Alright, I had the sudden urge to go make snake...Don't ask...

Now i feel totally lost...I have a basic script down that changes directions and all that, but I need help with altering the array so that 1 of them is a turning piece...

Ex: you change dir from 3 to 0, the spot that the head is on is now a turning piece and the head is now facing 0. When I tried to alter the array to turn, it moved the whole body up...

I am not a math techie...So this is a bit hard for me :-/
Script:

NPC Code:

---

if (playerenters) {

  toweapons Frogger;

  this.active=0;

}

if (weaponfired && this.active==0) {

  freezeplayer .6;

  playerdir=0;

  setani idle,;

  this.active=1;

  this.dir=3;

  this.head={4,9};

  this.tail={0,9,1,9,2,9,3,9};

  this.dirgo={0,-1,-1,0,0,1,1,0};

  timeout = .05;

}

if (timeout && this.active==1) {

  freezeplayer .6;

  setani idle,;

  for (this.i=0;this.i<arraylen(this.tail)/2;this.i++) {

    this.tail[this.i*2]+=this.dirgo[this.dir*2];

    this.tail[this.i*2+1]+=this.dirgo[this.dir*2+1];

  }

  this.startx=screenwidth/2-200;

  this.starty=screenheight/2-100;

  showimg 800,snakegrid.gif,(this.startx),(this.starty);

  changeimgvis 800,4;

  showimg 801,snakehead.gif,(this.startx+this.head[0]*32),(this.starty+this.head[1]*32);

  changeimgvis 801,4;

  for (this.i=0;this.i<(arraylen(this.tail)/2);this.i++) {

    showimg 802+this.i,snakebody.gif,(this.startx+(this.tail[this.i*2]*32)),(this.starty+(this.tail[this.i*2+1]*32));

    changeimgvis 802+this.i,4;

  }



  if (keydown(0) && this.dir!=2) this.dir=0;

  if (keydown(1) && this.dir!=3) this.dir=1;

  if (keydown(2) && this.dir!=0) this.dir=2;

  if (keydown(3) && this.dir!=1) this.dir=3;

  sleep .5;

  timeout = .05;

}
