Oh, i thought DistExecutor.runWhenOn can be called not depending on logical side. Thanks for information, i'll try fix it

I also tried it. Instead of world.getServer().getPlayerList().respawn(player, false) i tried DistExecutor.unsafeRunWhenOn(Dist.CLIENT, ()->()->Minecraft.getInstance().player.respawn()) but it actually did nothing

Sorry for not responding for a while. Here is my repo: https://github.com/mclich/ElderNorseGods.git A little update: the strange thing is that even an exception occurs, player will be teleported to spawn point anyway, but after that player just cannot move, break blocks or do any other action. Main camera still moves, but it looks like it "stuck" inside players head

So as i understand the exception occurs when game tries to delete player from the chunk, but can not find it there: public void removePlayer(SectionPos p_219367_1_, ServerPlayerEntity p_219367_2_) { long i = p_219367_1_.chunk().toLong(); ObjectSet<ServerPlayerEntity> objectset = this.playersPerChunk.get(i); objectset.remove(p_219367_2_); if (objectset.isEmpty()) { this.playersPerChunk.remove(i); this.naturalSpawnChunkCounter.update(i, Integer.MAX_VALUE, false); this.playerTicketManager.update(i, Integer.MAX_VALUE, false); } } objectset.remove(p_219367_2_) that line actually throws NullPointerException, am i right?

I have an item (basically totem), that will teleport player to its spawnpoint after fell in void. I use PlayerList#respawn method to teleport player back, but it throws NullPointerException. The code is below: private void activateTotem(World world, ServerPlayerEntity player, ItemStack itemStack) { player.fallDistance=0F; ItemStack totem=itemStack.copy(); Minecraft minecraft=Minecraft.getInstance(); if(world.dimension()==World.END) player.moveTo(100.5F, 49F, 0.5F); else player=world.getServer().getPlayerList().respawn(player, false); if(minecraft.gameMode.getPlayerMode().isSurvival()) itemStack.shrink(1); DistExecutor.unsafeRunWhenOn(Dist.CLIENT, ()->()->minecraft.gameRenderer.displayItemActivation(totem)); minecraft.particleEngine.createTrackingEmitter(player, ParticleTypes.PORTAL, 40); world.playSound((PlayerEntity)null, player.blockPosition(), SoundEvents.TOTEM_USE, SoundCategory.PLAYERS, 2F, 1F); player.playSound(SoundEvents.TOTEM_USE, 2F, 1F); } Is there any errors or am i just do something wrong?

A little update: i discovered that GameRenderer#renderConfusionOverlay just renders a nausea texture, not an actual distortion, which is not what i needed. I found information about EntityRenderer#setupCameraTransform, but it's not currently available in 1.16.5 forge version. In previous versions it looks like this: f2 = this.mc.thePlayer.prevTimeInPortal + (this.mc.thePlayer.timeInPortal - this.mc.thePlayer.prevTimeInPortal) * par1; if (f2 > 0.0F) { byte b0 = 20; if (this.mc.thePlayer.isPotionActive(Potion.confusion)) { b0 = 7; } float f3 = 5.0F / (f2 * f2 + 5.0F) - f2 * 0.04F; f3 *= f3; GL11.glRotatef(((float)this.rendererUpdateCount + par1) * (float)b0, 0.0F, 1.0F, 1.0F); GL11.glScalef(1.0F / f3, 1.0F, 1.0F); GL11.glRotatef(-((float)this.rendererUpdateCount + par1) * (float)b0, 0.0F, 1.0F, 1.0F); } As i understand, an actual distortion is caused by GL11 static methods. I tried to experiment with those methods and some render events to make nausea distortion effect, but it works not as i expected and still doesn't make what i want. Is there any EntityRenderer#setupCameraTransform method, but available in 1.16.5 forge version? Or maybe am i doing something wrong?

Is there way to use non-static methods? Maybe there is another anotation which looks at all methods?

I commented line which was creating event: //this.renderOverlay(new RenderTickEvent(Phase.END, 10F)); but it still doesn't work. My effect code actually do nothing now, and my createOverlay method is never called Already read the most of it

That is exactly what you have said previously I passed Phase.END to event constructor, so i guess there is no need in this

Well, i tried that, but i'm still getting the same error: IllegalStateException("Rendersystem called from wrong thread")

I actually tried nothing, i mean i don't even know where i can find method that creates potion particles in Forge library. Effect#applyEffectTick has two args: LivingEntity and int, and there is no such method in LivingEntity class. The only method i know and can use is World#addParticle, but if i use this method, potion particles from my effect and vanilla effects don't mix in one color, but they should do, so that is the issue. I aslo don't know what ParticleType should i use: ENTITY_EFFECT or AMBIENT_ENTITY_EFFECT, i don't know what is the difference between them

So i just need to call my overlay method inside that event listener? Like this e.g.? @SubscribeEvent public void renderOverlay(RenderTickEvent event) { if(event.phase==Phase.END) { this.createOverlay(); } } Sorry if i am asking obvious things, but i don't understand at all how this should works since RenderTickEvent is called after renderConfusionOverlay. To create overlay in game, i need to manually call my renderOverlay method?

Seems it won't help much in my case. I mean what i want to do is just make my own renderConfusionOverlay method, since i cannot use renderConfusionOverlay implementation because it needs to be called in a specific thread

In that case what method should i call in Effect#applyEffectTick to spawn them? I tried to find out in game files, but found nothing

Hello. In my mod i created my own Effect and registered it. What i want this effect to do when applying on player is create screen overlay animation, similar to Nausea Effect (or Confusion Effect). I've done some researching in game files and discovered renderConfusionOverlay method in GameRenderer class. This method is private, so i just copy-pasted it in my applyEffectTick method, but it didn't work. That method used some RenderSystem static methods inside itself, and they throwed IllegalStateException("Rendersystem called from wrong thread") when i tried to use them in my files. So that is the problem. Is there any way to implement such kind of an animation since renderConfusionOverlay doesn't work?

I have similar question, but in my case i am curious how to make effect produce less particles than usual, like particles from invisibility effect (their number is less comparing to other effects). Is there any way to achieve that?

Oh, it is just personal thing. I always use class name with its static fields (as well as this with non-static fields), even inside that class. It is easier for me to read my own code like this Jeez, it is finally working! Thank you so much, you are a legend

Of course i'm not. My DeferredRegister and its RegistryObjects are in one class, i just showed my container declaration line In my BreweryBlock class i have overrided AbstractBlock#use method: @Override public ActionResultType use(BlockState blockState, World world, BlockPos blockPos, PlayerEntity player, Hand hand, BlockRayTraceResult blockRayTrace) { if(world.isClientSide()) return ActionResultType.SUCCESS; else { TileEntity tileEntity=world.getBlockEntity(blockPos); if(tileEntity instanceof BreweryTileEntity) { player.openMenu((BreweryTileEntity)tileEntity) } return ActionResultType.CONSUME; } } I know that there is a way to open gui with NetworkHooks#openGui, but i don't actually know what is the difference between it and PlayerEntity#openMenu method

Seems the problem is with data field. In my registry file my container is registred like this: public static final RegistryObject<ContainerType<BreweryContainer>> BREWERY_CONTAINER=ENGContainers.CONTAINERS.register(BreweryBlock.ID, ()->IForgeContainerType.create(BreweryContainer::new)); IForgeContainerType#create by default returns null as PacketBuffer, so data field in my container constructor is null: public interface IContainerFactory<T extends Container> extends ContainerType.IFactory<T> { T create(int windowId, PlayerInventory inv, PacketBuffer data); @Override default T create(int p_create_1_, PlayerInventory p_create_2_) { return create(p_create_1_, p_create_2_, null); } }

This line: this(windowId, playerInventory.player.getCommandSenderWorld().getBlockEntity(data.readBlockPos()), playerInventory, playerInventory.player);

So i changed my constructors a little bit, here is the code: public BreweryContainer(int windowId, PlayerInventory playerInventory, PacketBuffer data) { this(windowId, playerInventory.player.getCommandSenderWorld().getBlockEntity(data.readBlockPos()), playerInventory, playerInventory.player); } public BreweryContainer(int windowId, TileEntity tileEntity, PlayerInventory playerInventory, PlayerEntity player) { super(ENGContainers.BREWERY_CONTAINER.get(), windowId); if(tileEntity!=null&&tileEntity instanceof BreweryTileEntity) this.tileEntity=(BreweryTileEntity)tileEntity; if(this.tileEntity!=null) { //if(!this.tileEntity.getLevel().isClientSide()) this.recipes=this.tileEntity.getLevel().getRecipeManager().getAllRecipesFor(ENGRecipeTypes.getBrewingType()); this.tileEntity.getCapability(CapabilityItemHandler.ITEM_HANDLER_CAPABILITY).ifPresent ( itemHandler-> { this.addSlot(new BottleSlot(itemHandler, 0, 35, 17)); this.addSlot(new BottleSlot(itemHandler, 1, 58, 17)); this.addSlot(new BottleSlot(itemHandler, 2, 81, 17)); this.addSlot(new FuelSlot(itemHandler, 3, 58, 53)); this.addSlot(new IngredientSlot(itemHandler, 4, 16, 53));
