It's actually a very small change to the script I made which made it walk in 4 ways :

NPC Code:

---

  for (i=0; i<4; i++) if (this.key[i]==true) {

    playermoved = true;

    this.dir = i;

    newx = this.x + this.dirgo[i*2]*this.speed;

    newy = this.y + this.dirgo[i*2+1]*this.speed;



    // Check for walls

    setarray wall,6;

    for (j=0; j<6; j++)

      wall[j] = onwall(newx+this.Cwalltest[i*12+j*2],

        newy+this.Cwalltest[i*12+j*2+1]);



    // Test for walls in front;

    if (wall[0]==true || wall[1]==true || wall[2]==true || wall[3]==true) {



      // Move the player outside of the wall

      if (i==0) this.y = int(this.y);

      else if (i==1) this.x = int(this.x+0.5)-0.5;

      else if (i==2) {

        if (this.y!=int(this.y)) this.y = int(this.y+1);

      } else if (i==3) {

        if (this.x+0.5!=int(this.x+0.5)) this.x = int(this.x+1.5)-0.5;

      }



    } else {

      // Apply new position

      this.x = newx;

      this.y = newy;

    }



    // Test 'sidemoves'

    if (wall[0]==true && wall[2]==false && wall[3]==false && wall[4]==false) {

      this.x += this.sidemove[i*4];

      this.y += this.sidemove[i*4+1];

    } else if (wall[0]==false && wall[1]==false && wall[3]==true && wall[5]==false) {

      this.x += this.sidemove[i*4+2];

      this.y += this.sidemove[i*4+3];

    }

    i=4;

  }

Note that I added an i=4 to the end of the thing to prevent diagonal movement.
