Serverside Joining of Clientside Player Functions

Joining classes to the Player Clientside is a useful feature that cuts down on replicate coding and makes important actions/data retrieving more easily accessible, however you have to use player.join("classname"); Clientside rather than whatever Clientside parts of the class script loading when joined Serverside and it seems as if your client has to retrieve the class script from the server before loading on the client, this causes a delay in the script being accessable which while possible to work around can be frustrating.

Would it be possible for Serverside player.join(""); (if not a seperate function) to also join Clientside functions to the player object, and as a result enabling these functions to be accessable as soon as the player logs in?

On a side note, it's annoying that you have to completely restart your client whenever a Clientside player class script is updated in order for it to kick in, this seems to be the case even if you unjoin and re-join the class to the player after updating.

I agree at the annoyance of restarting the client. It'd be nice if the delay was fixed as well. On Era we do:

PHP Code:


		
			
function onActionServerSide(cmd) {

  if (cmd = "requestReady") {

    player.triggerClient("gui", this.name, "clientsideReady");

  }

}

//#CLIENTSIDE

function onCreated() {

  player.join("player");

  player.triggerServer("gui", name, "requestReady");

}



function onActionClientSide(cmd) {

  if (cmd == "clientsideReady") {

    for (temp.weapon : player.weapons) {

       weapon.trigger("playerReady", null);

    }

  }

}

And then any scripts that call player functions can use the event onPlayerReady instead of onCreated. Hope that helps someone with this problem.

I find that some classes actually take longer to load than others (presumably down to their amount of characters), so I use an initialization class that waits until the function exists.

Probably not a bad idea. Something like

PHP Code:


		
			
while (! ("myfunction" in player.getFunctions())) {

  sleep(0.05);

}

More like:

Weapon/NPC -

PHP Code:


		
			
//#CLIENTSIDE
function onCreated(){
  this.onAttemptInitialize();
}

function canInitialize(){
  return player.hasFunction("myFunction");
}

function initialize(){
  player.myFunction();
}

Class -

PHP Code:


		
			
//#CLIENTSIDE
function onAttemptInitialize(){
  if(this.canInitialize()){
    this.initialize();
  }
  else{
    this.scheduleEvent(0.05, "AttemptInitialize", NULL);
  }
}

Bump.

What about...

PHP Code:


		
			
//#CLIENTSIDE

function onCreated() {

  loadclass("player");

  player.join("player");

}

Don't know if it's async or not though. If it is I guess it won't really help much.

Tested it, didn't work :(.

Eventually use onClassDownloaded(classname), or after joining you call a function, which will automatically wait until the classes are downloaded and then call the function.

Would this not still cause "function myFunction not found in script of npc" when logging into a level containing clientside NPCs that use a player function?

This seemed to work for me:

wNPC A:

PHP Code:


		
			
function onCreated() {

  this.join("test");

}



//#CLIENTSIDE



function onCreated() {

  this.leave("test"); // Not really necessary, just prevents function overwriting issues.

  player.join("test");

}

wNPC B:

PHP Code:


		
			
//#CLIENTSIDE

function onCreated() {

  player.hello();

}

Class: test

PHP Code:


		
			
//#CLIENTSIDE

public function hello() {

  player.chat = "world.";

}

Looks like it also resolves the 'have to restart client to update' issue as well. Just make sure A loads first, which should be as easy as placing it first in weaponsorder in server options.

Funnily enough before deciding to test this I tested the normal situation of logging in having restarted the client while containing a player.function clientside within weapon + NPC scripts onCreated, and the function happened to work each time, so I think this is only really a problem when lag is involved.

I'm not so sure this is the case with player objects, I have a class which is handling level types (nopk, quest, pk, spar etc) which is joined to players and a clientside wall checking script within a weapon, the problem can still occur when using these functions.

What he means is that you do one weapon which is using all needed classes, since it's preloading the classes for weapons.
