I achieved this by using LocalPlayer

Then you are only setting players pose on the client. The server has no idea that the player should be swimming, so there is nothing telling the other players that this player should be swimming.

Classes in the client package don't exist on the server.

Are those methods in the same class? Any code that interacts with client only code should be in a seperate class.

Minecraft#player is an instance of LocalPlayer, so the game tries to load that class in order to cast it.

Please provide a complete stacktrace and git repo.

[Event Class not working]

Only register the event handler one way, not both.

IntelliJ thinks the functions aren't called because the code that calls them is not normal code. You can safely ignore the warnings, as long as the methods are being called in-game (which you could check by setting a breakpoint and running debug).

[[solved][1.19.2] force crawl position on player entity and how to prevent getting suffocation damage]

When the player doesn't need to be crawling you need to set the forced pose back to null

[[solved][1.19.2] force crawl position on player entity and how to prevent getting suffocation damage]

You need to set/force the pose to Pose.SWIMMING

[[1.19.2] What is the type "C"?]

C is a generic parameter. You need to pass in an instance of C, which will be a subclass of Container which supports the RecipeType.

With the Generic parameters `<C extends Container, T extends Recipe<C>>`: if you look at the type of RecipeType.CRAFTING, you find it is a RecipeType<CraftingRecipe>, meaning the generic T is `CraftingRecipe`, which extends Recipe<CraftingContainer>, so your C type is CraftingContainer. So you need to provide an instance of CraftingContainer to match the items and get an output.

[[1.18]How do I find player position on a server?]

Minecraft code is obfuscated. It sounds like you are either trying to run non-obfuscated code, or trying to run client-only code on the server.

Please provide the full crash log, and ideally your source code in a git repository

[Making a delay in method]

does a capabilities has an onTick() method

You need to make your own capability, and you can give it whatever methods you want.

[Changing a vannila item]

You should be using events, there is an event for "Player right clicked with an item" (PlayerUseEvent or InteractEvent or something along those lines), and an event to add text to existing item tooltips, although I can't remember what the events actually are off the top of my head.

In your event handler, you need to check that the item is a stick, then perform your logic. It means that you don't have to replace the vanilla stick.

[Getting the config folder location in code]

Why don't you want to use the forge config system? What are you trying to achieve?

Any configuration should either be in datapacks or in forge configs, for maximum compatibility and ease of users changing things.

[1.18 Increase entity's speed and attack damage with an mob effect?]

@BogieninYou almost definitely shouldn't be setting the base value, that pretty much completely negates the point of the attribute system. You should add attribute modifiers to the entity instead.

 

@FantaLaToneI think you should be able to just add multiple attribute modifiers to the effect, although I haven't actually done it before. If not you can override the methods in the effect class to add/remove the modifiers (by UUID) when the effect is added/removed from an entity.

[How to get All Woods and their Planks?]

There isn't one, you have to loop through all the (shapeless) recipes and check them yourself (i.e. check that there is a single ingredient and it is in the logs tag (and probably also check the output is something sensible, as I mentioned before)).

Alternatively, you might be able to look up the recipes manually by looping through the items in the logs tag, converting them to a single ingredient, then looking up the recipe for that single ingredient. I haven't ever tried, so I don't know how that would work, but it is probably more efficient.

[How to get All Woods and their Planks?]

There is no "Exact code".

You need to loop through the list of logs (that you got from the tag), and then compare those blocks with recipes which you can find from the recipemanager.

Minecraft doesn't make any links between logs and planks other than the recipes. There is no good way to do what you want, because there is no way to define "Block Y is a plank version of log X". Just "If you craft log X by itself, you get block Y". If someone adds a recipe for a single log to a diamond block, does that make a diamond block a plank?

[How to make a custom slot for your armor in inventory?]

Even so, what is the advantage of making your own slot, deliberately stopping players using your mod with loads of other mods, and having to write the code (which is already written in the other mod) yourself?

[[1.16.5] [Forge 36.2.34] Cast Custom Item In Vanilla Honey Bottle Class]

You need to actually get the Item instance form the registry (by calling #get).

Also, DON'T SHARE VANILLA CODE! You do not have the rights to share it, and we can all look it up for ourselves.

[I want to make an item like lootbag]

implement the IItemHandler capability for the album itemstack and open the container when right clicking the item, just the same as you would for a block entity container

[[1.18.2] save entities in item nbt]

Is your saveEntity function called?

If you enable the debug data in game, can you see the tag on the itemstack (F3 + H I think allows you to view NBT by holding ctrl maybe? If not, there is always the data command)

Field field = Entity.class.getDeclaredField("dimensions");

You should save this somewhere static, instead of computing it every time.

I tried manually firing EntityEvent.Size on my overridden removeAttributeModifiers(), but to no avail.

That's not how forge events work. The event doesn't fire to set the size, it fires when the size is changed to allow mods to override it. It is called from the (mojmap) method `Entity#refreshDimensions`, so if you call that method you should restore the entity size. Alternatively, if you don't want to allow other mods to react to the change in size, just recompute the AABB as vanilla does (either setPos, or setBoundingBox(makeBoundingBox())), but I would strongly suggest using the first method.

[[1.18.2] Issue with 48x16 size block placed in the world]

The best approach is to do what vanilla beds and doors do i.e. have multiple blocks placed when you place the item. Then when you break any of the blocks, break them all and drop a single item.

[[1.18.2] Player.hurt() doesn't work]

7 hours ago, Koolade446 said:

the issue with this is if a player gets on a saw and player.tickCount % 20 is 14 the player could have 19 ticks or almost a whole second to get off the saw before a tick of damage would be delt so if they like ran across it they may not take damage.

There are 2 approaches to fix that: either increase the frequency and reduce the damage (e.g. % 10 do 0.75 damage) so that they have less chance to escape (but don't die instantly).

Alternatively, perform the check every tick, but save whether or not the player was on the blade the previous tick, and if not, start damaging once/sec. This approach requires you to save the tick that the player stepped on the blade however (and check that `(current tick - start tick) % 20 = 0`) as well as whether or not the player was previously on the blade. I would suggest using capabilities (or at the minimum an NBT tag containing your modid) for this approach

[[Solved] Why does this crash?]

Did you make sure to call `Registration.init()` from your main mod constructor?

[(1.16.5 MCP) shoot particles]

It is called setParticleSpeed using the mojang mappings, I'm not sure what it's called using the MCP ones, sorry.

[(1.16.5 MCP) shoot particles]

Unfortunately I haven't actually looked at particles before, so can't be much help.

However, if you look at the source of the constructor you are using you can see that it divides the velocity by the magnitude of the velocity (plus some other maths) so the particles won't move very far/fast.

I would suggest experimenting with the `setParticleSpeed` method, which just sets the raw values.

[[Forge 1.18.1] Prevent sending of packets too quickly from client to server]

So If I'm understanding you correctly, the packet should only contain 1. the number of levels i want to store or withdraw and 2. the position of the block i'm targeting?

Yes, although if you have a server side container (which I assume you do for a BlockEntity based GUI) then you should only need the first part, as you already know the block entity.

[[Forge 1.18.1] Prevent sending of packets too quickly from client to server]

Don't EVER trust the client to report the correct amounts. Do all calculation of amount on the server, and just send "client requested X amount" to the server. The server should then verify that there is that amount in the block before giving it to the player.

The client should never tell the server what the new amount in the block is.
