Fishing Rod

[Vatec]

Well I decided to make a fishing rod, basically the player gets told which key to press and then if they press the keys correctly in time they catch the fish. Right now I have all of it clientside which is very insecure, but I just want to get input on the neatness of my coding, and overall coding efficiency.

PHP Code:

//#CLIENTSIDE

// Stages: 0 Idle, 1 Fishing, 2 Reeling

function onCreated() {
  this.possibleKeys = {
    "a", "b", "c", "f", "g", "h", "i", "j"
  };
  this.possibleFish = {
    "Pike", "Bass", "Salmon", "Tuna"
  };
  this.keysPressed = 0;
}


function onWeaponFired() {
  if (this.fishingStage == 0) {
    if (onwater2(player.x + (vecx(player.dir) * 3), player.y + (vecy(player.dir) * 3), 2, 2)) {
      this.fishing = true;
      disabledefmovement();
      setani("grab", NULL);
      triggerserver("gui", this.name, "startFishing", player.communityname);
    }
  }
}

function GraalControl.onKeyDown(code, key) {
  if (key == this.currentkey && this.fishingStage == 2) {
    temp.pl.chat = "Pressed "@key;
    this.keysPressed++;
    nextKey();
  } else if (key != this.currentkey && this.fishingStage == 2) {
    gotAway();
  }
}

function onTimeout() {
  if (this.fishingStage == 1) {
    this.fishingStage = 2;
    setani("pull", null);
    nextKey();
  } else {
    gotAway();
  }
}

function gotAway() {
  settimer(0);
  this.fishingStage = 0;
  this.keysPressed = 0;
  enabledefmovement();
  setani("idle", NULL);
  player.chat = "It got away!";
}

function caughtFish() {
  this.fishingStage = 0;
  keysPressed = 0;
  enabledefmovement();
  setani("carry", NULL);
  temp.fish = getRandomFish();
  player.chat = "You caught a " @ temp.fish @ "!";
  //Add fish to players inventory
}

function nextKey() {
  if (this.keysPressed < 7) {
    this.currentkey = this.possibleKeys[int(random(0, this.possibleKeys.size() - 1))];
    player.chat = "Press " @ this.currentkey;
    settimer(1.5);
  } else {
    settimer(0);
    caughtFish();
  }
}

function getRandomFish() {
  return this.possibleFish[int(random(0, this.possibleFish.size() - 1))];
}
