Clientside player-joined class

[Yen]

Alright, people keep telling me that clientside portions of player-joined classes work.
I can't get them to.
Can anyone tell me what I'm doing wrong, or how to do it right? I've tried both 'function' and 'public function'
Nothing is happening.

PHP Code:

//#CLIENTSIDE
function onPlayerChats() {
  chat = "Zomg";
}

public function Clamp(value,clamp) {
  inc = clamp / 2;
  nval = value % clamp;
  if (nval >= inc) value += (clamp - nval);
  else value -= nval;
  return value;
}

-Tapsfoot.- I'm gonna bump, just incase people are only looking at the topic on top.. I need a kinda-quick answer.

That code is in a weapon script and you call Clamp() from another npc or so ?

[Yen]

That code is in a class.
The class is joined to the player by the Control-NPC.
The weapon is trying to call 'player.Clamp()'

?
Only weapons and npcs can have clientside code.
