Help Remote class manager aCis

[Bouloche]

Hi. I'm beginner in l2j/java dev and i'm on aCis latest private sources.
I try to make a remote class manager for open possibles classes transfert window when the character get lvl 20,40,76.
I have made a condition in PlayerStatus.java like that :

@Override
	public final boolean addLevel(byte value)
	{
		if (getLevel() + value > PlayerLevelData.getInstance().getRealMaxLevel())
			return false;
		
		boolean levelIncreased = super.addLevel(value);
		
		if (getLevel() == 20)
		{
			NpcHtmlMessage html = new NpcHtmlMessage(0);
			html.setFile("data/html/mods/classmaster/50000-2.htm");
			_actor.sendPacket(html);
		}

But the result when player get lvl 20 is :

 

I don't know how  get the available classes in my html. Or maybe i havent the good method. 
Maybe i must call the method in ClassMaster.java or run the command who open the class change window in class master (1stClass)
I'm a bit lost
Than you for your future help.

You cannot just push the HTML and hope it works. It might for static htmls, which are htmls that do not have a dynamic part that has to be replaced with something within the core, such as the %menu%. In this particular case, you would have to "create/request" a new instance of the ClassManager and call the proper method of the ClassManager instance to show the available classes. Worst-case scenario, you would have to change the logic in the ClassMaster a bit (build upon the existing logic) to make sure that it could work without a particular NPC (or in other words to work with NpcObjID = null) under certain conditions, such as an additional Config.MY_CUSTOM_CLASS_MASTER_ENABLED (just an example).


Here is what it might look like:

if (Config.ALLOW_CLASS_MASTERS && Config.MY_CUSTOM_CLASS_MASTER_ENABLED)
{
      // ADD_SOME_ADDITIONAL_CHECKS_FOR_CLASS_CHANGE_ELIGIBILITY_HERE
      new ClassMaster(_actor.getObjectId(), null).showChatWindow(_actor);
}

Thank you for your response and your advice. I will try to look in this direction but being a beginner, it seems a bit vague to me. It's totally the opposite of what I imagined.
