Joining and leaving classes

is there an event called when joining and/or leaving classes? Something along the lines of onJoinedClass(); and onLeaveClass();.

I'm at work right now so I cannot provide an exact example of what I'm currently doing but it's something along the lines of the following.

PHP Code:


		
			
functions loadClassData(temp.obj, temp.classlist) {
  for (temp.classname: temp.classlist) {
    if (temp.classname in temp.obj.joinedclasses) {
      temp.obj.(temp.classname @ "::onJoined")();
    } else {
      temp.obj.join(temp.classname);
      temp.obj.(temp.classname @ "::onJoined")();
    }
  }
}

I did a quick search and didn't see anything that stuck out.

Yes, there does happen to be an event that happens when you join a class. I'm certain about onClassJoined() but not too certain about onClassLeaves (or something similar).

Could not find any documentation on it and a forum search yielded no relevant post.

PHP Code:


		
			
onClassLoaded(str) event - a class script has been updated: name of the class

That's about it. What are you trying to achieve?

Ah, was looking for 'join' not 'class' when i was searching scriptfuctions

Double post since you wanted to know what i was trying to achieve.

For certain classes such as skills I want to load all the data such as names, icons and descriptions when it's initially loaded. It's more for the benefit of tool tips than anything else. I don't feel the need to make a database with descriptions and such of each. I only have 4 skills per class that i can load in a single array for each of them so it's not like i'm setting 50 flags with a huge amount of data in them. I didn't feel like it requires an SQLite table. I'll see if this resolves my issue when i get off work.

I have a similar approach on Maloria, although instead I make sure to load all the important classes upon login before proceeding with adding any weapons.

PHP Code:


		
			
function onActionServerSide(temp.command)
{
  if (temp.command == "initialized") {
    player.triggerAllWeapons("onPlayerInitialized");
    
    player.removeWeapon(this.name);
  }
}

public function loadClasses()
{
  if (player.classesLoaded)
    return echo(format("[%s]: Classes already loaded for player %s, aborting...", this.name, player.communityName));
  
  temp.classList = { // Array with the classes you want to preload
  };
  
  for (temp.className: temp.classList)
    player.join(temp.className);
  
  player.classesLoaded = true;
  triggerClient("gui", this.name, "loadClasses", temp.classList);
}

function onPlayerLogout(temp.playerObject)
  temp.playerObject.classesLoaded = false;

//#CLIENTSIDE
const DEBUG_MODE = true;

function onActionClientSide(temp.command)
{
  // Return if it's not the trigger sent from loadClasses()
  if (temp.command != "loadClasses")
    return;
  // Return if classes has already been loaded this session
  if (player.classesLoaded)
    return;
  
  temp.classList.copyFrom(params[1]);
  
  for (temp.className: temp.classList) {
    // Load the class to the player
    if (!player.isInClass(temp.className)) {
      player.join(temp.className);
      debug(format("[%s]: Joining class '%s'...", this.name, temp.className));
    }
    
    // Maybe the class is loaded already?
    if (isClassLoaded(temp.className)) {
      continue;
    }
    
    loadClass(temp.className);
    debug(format("[%s]: Class '%s' not loaded yet, loading...", this.name, temp.className));
    
    while (!isClassLoaded(temp.className))
      sleep(0.05);
  }
  
  player.classesLoaded = true;
  debug(format("[%s]: All classes loaded!", this.name));
  
  triggerServer("gui", this.name, "initialized");
}




function debug(temp.text)
{
  if (DEBUG_MODE)
    echo(temp.text);
}

I'm actually doing something more similar to your post than my original but sometimes joining clientside classes is touchy and unreliable as they don't load right away. I might need to add a sleep such as you have and that would probably resolve those issues.

onClassLoaded doesn't do anything it appears.

Are you giving your skills their own weapon script?

If so just store a 'this.description' flag for your other scripts to read from.

I'm creating them all in classes so I can easily use the same skills with NPCs such as baddies or friendly quest NPCs without rescripting them.

I'm not. Each skill has it's own class code. At some point, I made all skills useable by both players and NPC baddies, which was quite messy but worked quite nicely for spells and such that you'd want NPC baddies to be able to use. Old example of it:

PHP Code:


		
			
public function onUseSkill(target)

{

  temp.var = (objecttype() == "TServerPlayer" ? "clientr" : "this");

  temp.var2 = (objecttype() == "TServerPlayer" ? "client" : "this");

  

  // Name of this skill

  temp.skill = "melee";

  // Skill data

  temp.skill.copyFrom(this.skills.(@skill));

  // What hand is the player attacking with (MainHand/OffHand)?

  //this.(@temp.skill @ "_hand") = (this.(@temp.skill @ "_hand") == "MainHand" ? "OffHand" : "MainHand");

  this.(@temp.skill.indentifier @ "_hand") = "MainHand";

  // What is equipped in that hand?

  temp.identifier = this.equippedInSlot(this.(@temp.skill.indentifier @ "_hand"));

  temp.identifier = this.getItemIdentifier(temp.identifier);

  // Item data

  temp.item_data = CACHE.query("items", temp.identifier);

  

  if (var == "this") {

    (@var2).freezetimer = item_data.freezeTimer;

  

    setCharAni(this.gani_idle, "");

    setCharAni(this.gani_attack, "");

    

    if (this.width == NULL && this.height == NULL)

      temp.tarsize = { 2, 3 };

    else

      temp.tarsize = { this.width, this.height };

    

    this.dir = getdir((target.x + 1.5) - (this.x + temp.tarsize[0]/2), (target.y + 2) - (this.y + temp.tarsize[1]/2));

  }

  

  target.trigger("WeaponAttack", this, (@var).equipped_MainHand);

}



//#CLIENTSIDE

public function onUseSkill()

{

  temp.var = (this.objecttype() == "TPlayer" ? "player" : "this");

  

  // Is the player already busy?

  if ((@var).freezetimer > 0)

    return;

  

  // Name of this skill

  temp.skill = "melee";

  // Skill data

  temp.skill.copyFrom(this.skills.(@skill));

  // What hand is the player attacking with (MainHand/OffHand)?

  //this.(@temp.skill @ "_hand") = (this.(@temp.skill @ "_hand") == "MainHand" ? "OffHand" : "MainHand");

  this.(@temp.skill @ "_hand") = "MainHand";

  // What is equipped in that hand?

  temp.identifier = player.equippedInSlot(this.(@temp.skill @ "_hand"));

  //echo(this.(@temp.skill @ "_hand") @ ":" SPC temp.identifier);

  temp.identifier = player.getItemIdentifier(temp.identifier);

  // Item data

  temp.item_data = CACHE.query("items", temp.identifier);

    

  (@var).freezetimer = temp.item_data.freezeTimer;

    

  onSetAni(client.gani_idle);

  onSetAni(client.gani_attack);

}



function onSetAni(gani)

{

  if (player != NULL)

    setAni(gani, "");

  else

    setCharAni(gani, "");

}

(it's old, messy and made with poor styling - I haven't actually been using it since 2010)
