Display Gui when a Field in the players IEEP's is Empty/Null [UNSOLVED]

ItsAMysteriousYT · January 8, 2016

Hey there - its me again...

Yesterday i tried solving the weird GuiShowing problem i have mentioned in a previous post (Which somehow disappeard and does not happen to be here anymore). Well i try showing a Gui only some of the values in the ieep's of the player are null.That shouldn't be too complicated but somehow it does not work as it should - the Gui shows up every time the player joines the world even if the properties have been set previously.

I made some SysOuts in the saveNBT & loadNBT Methods and in there everything is set correctly. To transfer the data from Client- to Serverside i use packethandling and neither the handler nor the packet seem to have any errors cuz the data is beeing transfered correctly.

So what i am doing to bring up the Gui is i have a PlayerTickEvent in my eventhandler that looks like this:

@SubscribeEvent
public void updateRealLifeProps(PlayerTickEvent event) {
	if (RLMPlayerProps.get(event.player) != null) {
		tickrun++;
		RLMPlayerProps.get(event.player).circleOfLife();
	}

	if(RLMPlayerProps.get(event.player).name==""){
		event.player.openGui(RealLifeMod.instance, GuiModInit.ID, event.player.worldObj, 0, 0, 0);

	}

}

And i apply the RLMPlayerProps to the player in an OnEntityConstructing Event like this:

@SubscribeEvent
public void onEntityConstructing(EntityConstructing event) {
	if (event.entity instanceof EntityPlayer){
		if (RLMPlayerProps.get((EntityPlayer) event.entity) == null) {
			RLMPlayerProps.register((EntityPlayer) event.entity);
		}
                }

}

I think that should work perfectly right? But it won't. The Gui is beeing opened every time i join the world even if the props of the player where loaded correctly with the names (I have SysOuts for that). I think there might be another instance of the RLMPlayerProps that is causing this bug. So why is there another instance of the IEEP's when they are only registered if they are null?

You are using an entity as a key for a map? I don't think it's a good idea. While I don't know the specific mechanics of managing those, I imagine that each player that joins generates a new entity, which will never be the same as the ones stored - the hashes might not work due to some internal player data being different.

So somehow i need to get the old data and transfer it to the new - but how???

ItsAMysteriousYT · January 8, 2016

Okay i made a mistake i know that but why excactly is it pointless? You seem to know excactly what is causing this mistake but how can i solve it.

Ah yea okay - so i remove the null check but appart from that what could cause the problem? I checked - there are some IEEP's with the values i set before i closed the world, but somehow they are not applied to the player.

I also tried opening the gui from inside of my IEEP's - same problem.

What is it the point i am missing? What do i need to do so the properties are applied to the player correctly?

ItsAMysteriousYT · January 9, 2016

I removed the two null checks and the game instantly crashes. So is this my fault or a bug?

This is the crash - somehow it disappears when i check if the player's gender is null instead of checking wether the players name.equals(""):
