integer gets set globaly instead of per player.

Posted May 22, 201312 yr

I made an integer that can be set trough a gui, by clicking a button. this integer regulates a block that spawns on death.

imagine: player 1 sets a dirtblock to spawn on death.(integer 1)

player 2 sets a sandblock to spawn on death (integer 2)

when player one dies, the block spawned will be a sandblock, because player 2 changed it most recently.

the integers get set to the player's persisted nbt tag. both are called in the proxies, by sending a packet from the player to the server. packet gets send on button click.

here's some code

setter and getter for code. client and commonproxy


//CLIENTPROXY
public int getRenderID(String username) {
	if (MinecraftServer.getServer() != null && MinecraftServer.getServer().getConfigurationManager() != null) {
		EntityPlayer player = MinecraftServer.getServer().getConfigurationManager().getPlayerForUsername(username);
		if (player != null) {
			if(player.getEntityData().hasKey(player.PERSISTED_NBT_TAG) && player.getEntityData().getCompoundTag(player.PERSISTED_NBT_TAG).hasKey("renderID_"+username)) {
				return player.getEntityData().getCompoundTag(player.PERSISTED_NBT_TAG).getInteger("renderID_"+username);

You should be saving that information to the player not to the block.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

DO NOT PM ME WITH PROBLEMS. No help will be given.

the code comes from a stand alone gui, opened with a keyhandler.

But i'll check over the stuff that I save in the block too. only should be the playername, some strings and the integer.

p.s. > the integer also gets called out of the proxies, aswell as saved , in an IPlayerTracker

*self bump*

i would like to find a solution as soon as possible :-[

solved it. i was setting another integer in the main mod file. it would get its value from the proxies, but there's only one mod file, with one integer, so it would get set to the last player who set it's block value. deleted the integer and called in the method getRenderId directly.

Bad pathfinding for big mobs (1.21.1)

hey
do u want someone to make this for you

(((SOLVED))) Loading into certain worlds stuck on "Reading world data" then stops responding.

So, I tried this, and the world did load, but ALL of the modded items and things I had completely disappeared, as well as many unmodded things like my chests and items I was carrying. Any solutions?

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I do have to add that this is my answer for 1.12.2 but it should ALSO work for future versions.

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I know this was posted almost 3 years ago but this is for anyone who is still looking for an answer.

First, find your config folder. -> C:\Users\ (desktop user's name) \curseforge(or the application where you've downloaded you mod)\minecraft\Instances\config (The config folder should be in the same folder as your mods folder.) Once you click on the config folder, search for CustomNpcs.cfg. Once found, click on it (you can edit it using notepad) and search for the line "headweartype". Set the value to 0 if you want a 2d head layer, set it to 1 for a 3d head layer. Then save the options and you should be good to go from there! :)
