[Override Vanilla Blocks class]

Just to be sure this

    public static final Block GRASS_BLOCK = new GrassBlock(Block.Properties.create(Material.ORGANIC).tickRandomly().hardnessAndResistance(1.5F).sound(SoundType.PLANT)).setRegistryName("minecraft:grass_block");

 

is what is meant by 

either way didn't seem to make a difference

 

I have removed the use of base classes, this \/ is what I have replaced it with I am not sure if this is correct but the items seem to behave properly

  Reveal hidden contents

            new BlockItem(STONE, new Item.Properties().group(ItemGroup.BUILDING_BLOCKS)).setRegistryName("minecraft:stone"),

 

Despite all these changes I am still getting the same behavior, after some experimentation I have found that some world gen works properly

 

World gen that works:

Lakes-Lava and water above and under ground

Mine shafts

normal stone world gen

all ores

dirt, gravel, andesite, diorite, granite patches

 

World gen that doesn't work:

caves in stone 

grass blocks

sand

 

Attached picture displays strange behavior 

(I can't seem to partially quote a post on mobile)

 

That is not what I meant. You'll have to replace the constants in Blocks class via reflection.

[[1.15.2] How to speed up the build process?]

AFAIK no.

How big is your mod (the compiling time shouldn't be significant unless the mod is big, like more than 1 million lines of code)?

What is taking up such a long time according to the log?

Can backdoors be prevented by simply not allowing assholes online to do the work on plugins for you that they can use to backdoor your server?

Yes (that is the definition of backdoor - coders creating exploits in the code for their personal gain).

Or there is something else that can be used to backdoor using minecraft glitches that is unprevented/difficult to fix and your server becomes backdoored.

In that case, the problem is not "backdoor", but rather "cheating/hacking" (depending on whether the situation happens in-game or on your server). There are anti-cheat plugins that you can use to prevent the former.

[Override Vanilla Blocks class]

1. Don't use bases. They are an abuse of inheritance.

2. Try replacing the constant values of items and block in Items and Blocks class respectively with your custom instances. I haven't met this exact problem before, but I guess it is caused by vanilla's still trying to use the original values from those two classes.

[[1.15.2] How to speed up the build process?]

You don't need to build the jar to test your mod.

Simply launch the client via gradlew runClient or the equivalent shortcut in your IDE.

[[1.15.1] How do you check what a player is holding in their hand?]

We do not provide copy-paste code on this forum.

Which part do you not understand?

If you want the effect to occur on a vanilla item (as opposed to a custom item added by your mod), subscribe to PlayerTickEvent and check for the item in hand instead.

[[1.15.1] Potion effect stuck at 0 time left]

You need to learn about the concept of sides.

Input events are client side; you cannot do anything that would affect the server (interact with world, blocks, entities, etc).

Instead, subscribe to PlayerTickEvent, and check if the event is fired on the server side and check PlayerEntity#isSneaking for sneaking.

[Problem setting block with tile entities]

This is nostalgic... Reminded me of that time back in middle school where we were asked to make a chess game in Java as a class assignment.

 

Back on topic. If you really want to reference the chess controller from every single chess piece, then I guess you could make a tile entity for each of them (or even make the chess pieces into entities, which is something I would do since you can create the animation of chess pieces sliding across the board). From that point on, just send all interactions on the chess pieces to the chess controller and let it handle the logic. Note that the chess piece should only store the BlockPos of the chess controller, and fetch the actual tile entity of it when it is actually needed.

 

On a side note, I think that with the new way block properties are handled after the flattening, it is possible to store the chess controller's BlockPos as a property instead of creating a tile entity for it. Not sure if that is a good idea from the design perspective though.

[[1.15.1] How do you check what a player is holding in their hand?]

Override Item#onUpdate (which is called every tick if an instance of the item is in the player's inventory) and check if the isSelected parameter is true (which will be true if the player is holding the item). If true, the check if the player is crouching (PlayerEntity#isSneaking or something) and apply your effects.

Is it possible or is there any variable to change the reach radius to be around my hand at a certain player height?

That is changeable in the player's attribute. Obtain the attribute via LivingEntity#getAttribute and pass in the REACH_DISTANCE in PlayerEntity to obtain the reach attribute. You can modify that to change block reach distance.

Unfortunately I don't think there is a convenient method of changing the reach for entity interactions. You'll have to do some manual ray casting.

[Spawn Entity from code]

Use World#addEntity (spelling might be off), and pass in an instance of the desired entity.

[[1.15.2] Setting player's eye height]

1. You need to use ObfuscationReflectionHelper (can’t remember the exact spelling).

2. Reflection is expensive. Use it once and store the result in a static field and use that from now on.

3. You should directly reference PlayerEntity.class instead of using getClass.

[Place Block as Player]

Is this a client only mod?

What would be the function to be like from the end user's perspective?

You could just send a right click input to place the block down.

[Changing player size]

Oh I'm just being lazy there.

Instead of finding the registry reference during the appropriate time, I used a LazyValue to find it via GameRegistry.findRegistry the first time I call it.

It is functionally the same with:

if (registry == null) {
	registry = findRegistry();
}

doStuffWithRegistry();

 

[[1.15.2] Isometric View]

Note that you also shouldn't look up methods via reflection every time the camera updates.

Look them up once, and store them in a static field.

I don't really understand how would I encode/decode something that isn't primitive >.<

There are helper functions that allows you to encode complex data (such as ITextComponent and BlockPos) to NBT.

I'm trying to sync the capabilities, is making a list of all the capabilities a good start?

I personally store my capabilities in static fields marked with @CapabilityInject annotation so that the value of the capability is injected at runtime. An example is this.

 

Here are some links to the capability part of my test mod if you need:

My capability object.

My capability provider.

My capability storage.

My event subscriber for attaching capabilities to player.

My packet that syncs the data of capability to the client.

[Does anyone know how to add a potion effect to armor (1.15.2)]

Quote

event.getRegistry().register(new ArmorItem(ModItemTier.ModArmorMaterial.TEST, EquipmentSlotType.LEGS,

                new Item.Properties().group(RareMetalsRevised.TAB)).effect.(new EffectInstance(Effects.ABSORPTION,600, 5)).setRegistryName("rhodium_leggings"));

That is not valid Java. Please learn Java before making a mod.

I would also suggest to get more familiar with your IDE so that you can understand its warnings and errors.

Your next line is, "1.10.2 is no longer supported on this forum. Please update to a modern version of Minecraft to receive support"!

Is that a JoJo reference?

[Task 'setupDecompWorkspace' not found in root project 'Forgemod'.]

By "that directory" I meant the mdk directory (the one containing gradlew).

Pronouns such as "that" usually refers to the appropiate object mentioned immediately before the current sentence, and in this case, it is the mdk directory (note that gradlew is a file, not a directory).

[Does anyone know how to add a potion effect to armor (1.15.2)]

Please post the error.

Please also post the code using services like pastebin, as it is currently almost unreadable.

[Changing player size]

You should sync capabilities of other players to the client.

Sorry, I'm a bit confused. What do you mean by this? I have a launcher profile for 1.15.2 forge.

You should use different launcher profiles for different versions of Forge. Each of them can point to a different game directory, and you can keep your mods separated.

[[1.15.2] Version-specific mods folder not recognized]

That feature has been removed. Use launcher profile instead.

[Should I add server check on item ?]

If something actually affects the game (like changes to the world, as well as inventory), then it should be done on the server.

Think to yourself "if the player can freely edit this value/call this function, would that affect other players as well as bring an unfair advantage/disadvantage?" If yes, then throw it on the server.

[Changing player size]

Make the player size a capability and sync it everywhere (not literally; only to tracking clients and self), and on the client, render the model based on that player's size capability.
