GS3 Speedhack Detector

Just got bored and decided to play around with GS3.
It's really quite simple, but it works effectively.

PHP Code:


		
			
//#GS3
//#CLIENTSIDE
var op:number;
function onCreated():void{
  op = {player.x, player.y, player.level};
  this.onTimeout();
}
function onTimeout():void{
  //Check the distance between the players last position
  //and their current position.
  var d:number = this.Dist(op[0], player.x, op[1], player.y);
  //d is the distance traveled in the last second
  //if(player.level == op[2] && d > 30){   
  //Set the old position
  op = {player.x, player.y, player.level};
  this.settimer(1);
}
//Pythagoras, get the distance between two points
function Dist(x1:number, x2:number, y1:number, y2:number):number{
  return (((x1-x2)^2)+((y1-y2)^2))^0.5;
}

Since d is as constant as op, isn't it more efficient to declare d over the scope of the entire script as well?

But d is only used once, where as op needs to be stored? It's like doing temp. When it's inside a method, but possibly.

This doesn't take into account if I enter a new level

Also, now days stuff like speed hacking gets insta-reported

Still doesn't hurt if there's detection, sometimes a player won't catch it quickly enough.

What if a player is summoned?? either by staff, or script.. nice to see people trying to adpoted GS3 so early. I plan on learning it myself and have enabled it on my server for testing.

Just use vectordist({ox, oy, oz}, {fx, fy, fz}) instead of re-creating your own.

Re-created it to be more efficient though, no need to do extra operations on z.

How is this legal...?

I don't even know, I tried var op:number[]; but it errored.

player.level is a TServerLevel, not a number. Does the client even implement GS3 yet? I very much doubt it since they're still pushing very basic updates to the server with regularity. My guess is it's just ignoring that syntax (as it has been for years in GS2), meaning that your script is not actually valid GS3 (but instead valid GS2). Not positive on that though.
