Weird bug on server

Recommended Posts

I have a block which changes the time, but when I choose one of the options and on client it changes the time, on server. Either it doesnt do anything, or it gives me an NPE on the if() lines, code:

 


public void actionPerformed(GuiButton guibutton)
{
	if(guibutton.id == 1)
	{
		for (int var3 = 0; var3 < MinecraftServer.getServer().theWorldServer.length; ++var3)
		{
			MinecraftServer.getServer().theWorldServer[var3].setTime(7000);
		}

	}

	if(guibutton.id == 2)
	{
		for (int var3 = 0; var3 < MinecraftServer.getServer().theWorldServer.length; ++var3)
		{
			MinecraftServer.getServer().theWorldServer[var3].setTime(17000);
		}

	}

	if(guibutton.id == 3)
	{
		for (int var3 = 0; var3 < MinecraftServer.getServer().theWorldServer.length; ++var3)
		{
			MinecraftServer.getServer().theWorldServer[var3].setTime(0);
		}

	}

	if(guibutton.id == 4)
	{
		for (int var3 = 0; var3 < MinecraftServer.getServer().theWorldServer.length; ++var3)
		{
			MinecraftServer.getServer().theWorldServer[var3].setTime(13000);
		}

	}

}

Because the GUI classes are only called client-side. If you call MinecraftServer.getServer() in a client, it gives you only the InternalServer. If you are connected to a dedi server, it gives you a null object (unless you call this method on the dedi server).

I would recommend to send packets for this one.

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.
