[[1.20.2] Access Transformers]

That helped🥳. Thank you a lot!

[[1.20.2] Access Transformers]

Hi,

I need to accesses byPath field of net.minecraft.client.renderer.texture.TextureManager. As I found out I need to use accesstransformer.cfg file and make the field public via it. In this file field names of class look like f_<numbers>. And I was unable to figure out, how to get those. It seems like it is connected to something called mappings (thing left after Minecraft decompile process). How can I get such a name for a field of a class?

[[1.18.2] How to get painting entity at block position]

Thanks! By the way, does this method return creatures/minecarts/ect. as part of list?

[[1.18.2] How to get painting entity at block position]

Hi,

Let say I have an instance of ServerLevel and I what to get a painting as entity at BlockPos. level.getBlockEntity(pos) (level is instance of ServerLevel) returns null for some reason. How can I get painting at given position (if it exists there)?

[[1.18.2] Minecraft render types]

Hi

I have recently developed Minecraft mod, that exports world portions, which then are imported with my Blender addon into Blender scene. The idea was to be able to export modded minecraft worlds. Currently it proved to work nicely. But there are 2 majior drawbacks:
1) It does not export paintings, armor stands and item frames.
2) It does not export blocks, that use custom renderers (like chisel and bits mod blocks)

My approach is that I ask minecraft renderers (BlockRenderDispatcher, BlockEntityRenderDispatcher) to render what they see at some block position into my custom VertexConsumer classes.

Seems like I am missing some other types of renderes.

How paintings, armor stands and item frames render themselves? Can I somehow access renderers, that are introduced by other mods?

[[1.18.2] Any events fired after resources are loaded]

I'm not going to try and debug your random code snippets out of context.

Well, nobody was asking for that.

By the way, why are you using class approach and not MinecraftForge.EVENT_BUS.addListener or FMLJavaModLoadingContext.get().getModEventBus().addListener?

[[1.18.2] Any events fired after resources are loaded]

Well, I've added

FMLJavaModLoadingContext.get().getModEventBus().addListener(
                EventPriority.NORMAL,
                false,
                RegisterClientReloadListenersEvent.class,
                this::a);

into my mod constructor. a is

private void a(RegisterClientReloadListenersEvent event){
        LOGGER.debug("Resources loaded");
    }

And it seems it is not working (I don't see this string in console)

[[1.18.2] Any events fired after resources are loaded]

After game is loaded or resource-packs are reloaded debug console fill with some info, ending with:

[[1.18.2] Check if block at given position is grass/foliage/water]

29 minutes ago, warjort said:

No, that is the color when it is drawn on a map item.

 

If you want the custom color of a block, look at the BlockColors class e.g.

BlockColors.getColor(BlockState, Level, BlockPos)

The instance the game uses is a private field in the Minecraft class, so you will need to use an access transformer.

https://forge.gemwire.uk/wiki/Access_Transformers

Thanks!

By the way, getColor returns int. How it is converted to RGB or something of that kind?

[[1.18.2] Check if block at given position is grass/foliage/water]

what do you need?

Well, to make things clear. You might know that things like BlockEntityRenderer are used by Minecraft to render things into our monitor. But lets say I have asked such renderers to render some portion of the world into my own buffer => I got Minecraft geometry as it is rendered right now in my screen. I also dumped current texture atlases as .png (basic ones, because I can't yet figure out how to get full list of atlases in code). So I got geometry, I got textures. But:

those green stuff are usually gray (in png files)

I need to know color for each block to setup Blender materials, so it will look exactly, like in my world. Because right now all grass/water/leaves are in greyscale. So, I want to know that:

then, the developer tells the game how to recolor these parts of the model.

[[1.18.2] Check if block at given position is grass/foliage/water]

17 hours ago, warjort said:

But I think you will find what you are talking about works the opposite way.

So, maybe, it can be done like this?

block.getMaterial().getColor().col

I found out I can call such thing from a BlockState. Is that a current block color?

[[1.18.2] Check if block at given position is grass/foliage/water]

Most Biomes in Minecraft have unique grass/foliage/water color. It can be accessed via methods .getFoliageColor(), .getGrassColor() and .getWaterColor() of the Biome class. That means, technically, that game has an awairness of whenever block is grass/foliage and fluid is water. Am I able to gain such awairness too? Considering that I have access to instance of ServerLevel class and BlockPosition, where I want to check these conditions.

[[1.18.2] Make block temporarily invisible]

Well, I inserted bunch of code to just point out the place, where I want this to happen, because I my opinion task "make block at BlockPosition invisible" is quite scenario independent. I was asking if something like level.setBlockInvisible(position) is possible (level is instance of ServerLevel).

[[1.18.2] Make block temporarily invisible]

Well, the scenario... It's quite complicated. You can view the whole source code here:

https://github.com/Dreadoom/RenderCube

I am interested in this piece of code:

// Min and max coordinates over each axes
int region_min_x = Math.min(position1.getX(), position2.getX());
int region_max_x = Math.max(position1.getX(), position2.getX());
int region_min_y = Math.min(position1.getY(), position2.getY());
int region_max_y = Math.max(position1.getY(), position2.getY());
int region_min_z = Math.min(position1.getZ(), position2.getZ());
int region_max_z = Math.max(position1.getZ(), position2.getZ());

// Loop over coordinates
for(int x = region_min_x; x <= region_max_x; x++){
	for(int y = region_min_y; y <= region_max_y; y++){
		for(int z = region_min_z; z <= region_max_z; z++){
			// Current block position
            BlockPos position = new BlockPos(x, y, z);

			// Process block
			boolean success = RenderCubeUtils.renderBlock( source, jsonWriter, position, new BlockPos(
                                        position.getX() - region_min_x,
                                        position.getY() - region_min_y,
                                        position.getZ() - region_min_z));

			// We finish with success only if RenderCubeUtils.RenderBlock(...) returned true
			if(!success){
				// Finish with failure
				return -1;
           	}
		}
	}
}

I want it to look something like this:

// Min and max coordinates over each axes
int region_min_x = Math.min(position1.getX(), position2.getX());
int region_max_x = Math.max(position1.getX(), position2.getX());
int region_min_y = Math.min(position1.getY(), position2.getY());
int region_max_y = Math.max(position1.getY(), position2.getY());
int region_min_z = Math.min(position1.getZ(), position2.getZ());
int region_max_z = Math.max(position1.getZ(), position2.getZ());

// Loop over coordinates
for(int x = region_min_x; x <= region_max_x; x++){
	for(int y = region_min_y; y <= region_max_y; y++){
		for(int z = region_min_z; z <= region_max_z; z++){
			// Current block position
            BlockPos position = new BlockPos(x, y, z);
                                                   
            if(x == region_min_x){
            	makeInvisible(position.mutable().setWithOffset(position, Direction.WEST)));
            }
            // Same for other 5 vars

			// Process block
			boolean success = RenderCubeUtils.renderBlock( source, jsonWriter, position, new BlockPos(

[[1.18.2] Make block temporarily invisible]

Let's say I have those 2 variables:

ServerLevel level = source.getLevel();

BlockState block = level.getBlockState(levelPosition);

I want to make block near one I got (in any direction) temporarily invisible, perform some actions with block I have and then make invisible one visible again. How can I do this?

[[SOLVED][1.18.2] .getQuads(...) does not get quads for beds/chests/fluids/ext.]

Well, I hope this picture explains my intentions:

https://drive.google.com/file/d/1BTx4zqqn6_K-P3j7d_iK2hb4Ia3t6HKv/view?usp=share_link

[[SOLVED][1.18.2] .getQuads(...) does not get quads for beds/chests/fluids/ext.]

By the way, I see a lot of renderers use VertexConsumer. Seems like all renderers use them to send verticies to graphics engine. Can I make such consumer and act as OpenGL to get rendered verticies in a block?

[[SOLVED][1.18.2] .getQuads(...) does not get quads for beds/chests/fluids/ext.]

Thanks warjort. I was afraid, that this is because they are entities. Now I know where to dig.

But what about water, for example? I have checked via debug code, that there is no entity there (appropriate method return null). What is wrong with liquids?

[[SOLVED][1.18.2] .getQuads(...) does not get quads for beds/chests/fluids/ext.]

When I try to get quads for beds/chests/fluids via this code

// Get level, where command is executed
ServerLevel level = source.getLevel();

// Get BlockState at position
BlockState block = level.getBlockState(levelPosition);

// We do not want to render air
if (!block.isAir()) {
	// Is used to get IBakedModel
	BlockRenderDispatcher blockRenderer = Minecraft.getInstance().getBlockRenderer();

	// Is used in getQuads(...)
	Random rand = new Random();

	// Rendered block
    RenderedBlock renderedBlock = new RenderedBlock(regionPosition.getX(),
                                                    regionPosition.getY(),
                                                    regionPosition.getZ());

    // Block extra model data
    IModelData data = blockRenderer.getBlockModel(block).getModelData(level, levelPosition, block, EmptyModelData.INSTANCE);

    // Get model quads
    List<BakedQuad> quads = blockRenderer.getBlockModel(block).getQuads(block, null, rand, data);

   	// List of all possible directions
    ArrayList<Direction> directions = RenderCubeUtils.getAllPossibleDirections();

    // Through all directions
    for (Direction direction : directions) {
    	// Get model quads, corresponding to this direction
        List<BakedQuad> quadsTemp = blockRenderer.getBlockModel(block).getQuads(block, direction, rand, data);

        // Join lists of quads
        quads = Stream.concat(quads.stream(), quadsTemp.stream()).toList();
	}
}

I get empty 'quads' list. Why is this happening? How can I fix this?

[[1.18.2] How to get texture atlases resource locations]

Hi there,

Is there a way I can get texture atlases ResourceLocation in Minecraft 1.18.2 forge? Or something like it, because on startup game log has these lines:

This means somewhere there is ResourceLocation that holds these files. I can get, for example, minecraft:textures/atlas/blocks.png-atlas via this code

TextureManager textureManager = Minecraft.getInstance().getTextureManager();
TextureAtlas textureAtlas = (TextureAtlas) textureManager.getTexture(new ResourceLocation("textures/atlas/blocks.png"));

but what if, for example, some mod has added new atlas? I want to get whole list of those, via something like this

Collection<ResourceLocation> resourceLocations = Minecraft.getInstance().getResourceManager().listResources(
                    "textures/atlas",
                    res -> res.chars().noneMatch(i -> Character.isLetter(i) && Character.isUpperCase(i)));

but this approach sadly is not working.

[[SOLVED][1.18.2] Get texture file of BakedQuad]

Well, now, when I understand this a bit better, question has changed. I need a way to get this big composite image(s), the TextureAtlas(es) and save as .png or something.

[[SOLVED][1.18.2] Get texture file of BakedQuad]

Well, minecraft is obviously able to interpret that stream as 2D image. Am I able to interpret it the same way? And create usual image from that stream.

[[SOLVED][1.18.2] Get texture file of BakedQuad]

Hi there,

Let's say, I've got a BakedModel via this code

BlockRenderDispatcher blockRenderer = Minecraft.getInstance().getBlockRenderer();
BakedModel blockModel = blockRenderer.getBlockModel(block);

where block is an instance of BlockState. Then I do

List<BakedQuad> quads = blockModel.getQuads(...);

to get all BakedQuads of this model.

While I iterate over them, I want to get a texture file (eg. .txt or .jpg) witch each of this quads use. Is that possible, and, if so, how can I do that?

P. S. I see, that BakedQuad has a TextureAtlasSprite inside, witch I can get, but I don't know if that is what I need, and how to get texture file from it.
