[SOLVED] [1.10.2] Proper TileEntity rendering

Posted December 10, 20168 yr

I don't know if this is a bug or my error, but MC freezes, when I pass more than one property to the BlockStateContainer.

Example code:

public static final PropertyDirection FACING = BlockHorizontal.FACING;
    
public static final PropertyEnum<EnumConnectionType> connectionTop = PropertyEnum.create("connection_top", EnumConnectionType.class);
public static final PropertyEnum<EnumConnectionType> connectionBottom = PropertyEnum.create("connection_bottom", EnumConnectionType.class);
public static final PropertyEnum<EnumConnectionType> connectionNorth = PropertyEnum.create("connection_north", EnumConnectionType.class);
public static final PropertyEnum<EnumConnectionType> connectionWest = PropertyEnum.create("connection_right", EnumConnectionType.class);
public static final PropertyEnum<EnumConnectionType> connectionSouth = PropertyEnum.create("connection_front", EnumConnectionType.class);
public static final PropertyEnum<EnumConnectionType> connectionEast = PropertyEnum.create("connection_back", EnumConnectionType.class);

...

@Override
protected BlockStateContainer createBlockState()
{
     return new BlockStateContainer(this, FACING, connectionTop, connectionBottom, connectionEast, connectionNorth, connectionSouth, connectionWest);
}

Am I doing something horribly wrong? If you need to see more code, ask for it.

I have a suspicion the constructor calls itself because of the varargs:

    public BlockStateContainer(Block blockIn, IProperty<?>... properties)
    {
        this(blockIn, properties, null);
    }

    ...

    protected BlockStateContainer(Block blockIn, IProperty<?>[] properties, ImmutableMap<net.minecraftforge.common.property.IUnlistedProperty<?>, com.google.common.base.Optional<?>> unlistedProperties)
    {
        ...
    }

You need to pass an array of properties, e.g:

	@Override
protected BlockStateContainer createBlockState() {
	return new BlockStateContainer(this, new IProperty[] {Props.AXEL_ORIENTATION, BlockHorizontal.FACING});
}

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.

Everythings points to the BlockStateContainer class. I noticed the createState method is called repeatedly until I kill java.

I noticed it works at 4 - 6 IProperties too, but it takes 5 seconds for 4 props and about a minute for 6 props.

EDIT

Wait, does BlockStateContainer on creation generate every single combination of IProperty values? If so, that would be 6 million combinations with 7 Properties (1 side property and 6 properties with 10 different values each).

I need theese IProperties for my BlockState JSON, or is there a better way of custom side rendering based on TileEntity data? Tesselator is gone if I remember correctly.

The question is:

Why do you need 10 values for each of 6 different properties?

Tesselator is not gone in 1.10.2.

So I rewrote most of the model to TESR and it works fine, except the entire block is very very dark. Like white -> dark gray.

	return buffer;
}

UPDATE

It seems the less light the block has, the brighter it is.

That was just an optical illusion.

The block doesn't get lit at all.

Try disabling the lightning instead of enabling it. And you take into account somethings before using a TESR. Is it supposed to be rendered dynamically? Can it be made using JSONs, can it be made using OBJ models, can you make it using IBakedModels? If it cannot and is not fulling dynamic you need to find a way to render it not every frame, but only when it needs to be rendered.

And even if you do need a TESR, don't do

Minecraft.getMinecraft().getTextureManager()

a lot. Save the reference to a variable and that'll clean up your code A LOT.

That was a temporary solution. Otherwise I am very tidy with my code.

I forgot to explain what I am trying to achieve. I have a full, opaque block and I want to draw overlay on each side similar to EnderIO reconfigurable sides. I already rewrote the system again to render the original block normally (using JSON) and then draw the overlay quads with TESR.

It works except for the lighting problem.

Anyway, it's 11 44 PM in my country, so I will check other options you suggested and post my new render code tommorrow.

So, update.

I was looking for a solution somewhere else and I found a solution for the dark shading:

int li = te.getWorld().getCombinedLight(te.getPos(), 15728640);
int u = li % 65536;
int v = li / 65536;
OpenGlHelper.setLightmapTextureCoords(OpenGlHelper.lightmapTexUnit, u, v);

Not sure what it does, because it is not documented.

There is one problem, it ignores block lighting and uses only sky lighting.

My new render code:

private static final int GL11_GL_QUADS = 0x7;
protected final ResourceLocation frontTex = new ResourceLocation(SECore.MOD_ID, "textures/blocks/machines/overlay.png");

public void renderTileEntityAt(TileEntityMachinePowered te, double x, double y, double z, float partialTicks, int destroyStage)
{
GlStateManager.pushMatrix();
GlStateManager.translate(x + 0.5, y + 0.5, z + 0.5);		
GlStateManager.disableLighting();
GlStateManager.color(1, 1, 1, 1);
GlStateManager.disableCull();

int li = te.getWorld().getCombinedLight(te.getPos(), 15728640);
int u = li % 65536;
int v = li / 65536;
OpenGlHelper.setLightmapTextureCoords(OpenGlHelper.lightmapTexUnit, u, v);

Tessellator tessellator = Tessellator.getInstance();

Minecraft.getMinecraft().getTextureManager().bindTexture(frontTex);		

if(te.connectionType[EnumFacing.NORTH.getIndex()] != EnumConnectionType.DEFAULT)
{
	storeSide(tessellator.getBuffer(), te.connectionType[EnumFacing.NORTH.getIndex()].getFloatUVs());	
	tessellator.draw();			
}

GlStateManager.rotate(90, 0, 1, 0);

if(te.connectionType[EnumFacing.WEST.getIndex()] != EnumConnectionType.DEFAULT)
{
	storeSide(tessellator.getBuffer(), te.connectionType[EnumFacing.WEST.getIndex()].getFloatUVs());	
	tessellator.draw();			
}

GlStateManager.rotate(90, 0, 1, 0);

if(te.connectionType[EnumFacing.SOUTH.getIndex()] != EnumConnectionType.DEFAULT)
{
	storeSide(tessellator.getBuffer(), te.connectionType[EnumFacing.SOUTH.getIndex()].getFloatUVs());	
	tessellator.draw();			
}

GlStateManager.rotate(90, 0, 1, 0);

if(te.connectionType[EnumFacing.EAST.getIndex()] != EnumConnectionType.DEFAULT)
{
	storeSide(tessellator.getBuffer(), te.connectionType[EnumFacing.EAST.getIndex()].getFloatUVs());	
	tessellator.draw();			
}

GlStateManager.rotate(90, 0, 1, 0);
GlStateManager.rotate(90, 1, 0, 0);

if(te.connectionType[EnumFacing.UP.getIndex()] != EnumConnectionType.DEFAULT)
{
	storeSide(tessellator.getBuffer(), te.connectionType[EnumFacing.UP.getIndex()].getFloatUVs());	
	tessellator.draw();			
}

GlStateManager.rotate(180, 1, 0, 0);

if(te.connectionType[EnumFacing.DOWN.getIndex()] != EnumConnectionType.DEFAULT)
{
	storeSide(tessellator.getBuffer(), te.connectionType[EnumFacing.DOWN.getIndex()].getFloatUVs());	
	tessellator.draw();			
}

GlStateManager.popMatrix();
}

private VertexBuffer storeSide(VertexBuffer buffer, float[] uvs)
{
buffer.begin(GL11_GL_QUADS, DefaultVertexFormats.POSITION_TEX);
double smallShift = .01;

buffer.pos(-0.5, -0.5, -0.5 - smallShift).tex(uvs[0], uvs[3]).endVertex();
buffer.pos(-0.5, 0.5, -0.5 - smallShift).tex(uvs[0], uvs[1]).endVertex();
buffer.pos(0.5, 0.5, -0.5 - smallShift).tex(uvs[2], uvs[1]).endVertex();
buffer.pos(0.5, -0.5, -0.5 - smallShift).tex(uvs[2], uvs[3]).endVertex();

return buffer;

Not sure what it does, because it is not documented.

There is one problem, it ignores block lighting and uses only sky lighting.

Gets the light value at the block coordinates the TE is at, in a combined manner:

i << 20 | j << 4

where i is SkyLight and j is BlockLight.

"15728640" is just a "if the actual block light is less than this value, use this value" value. This means that regardless of the total light in the space, this value will be used pretty much guaranteed (as 15728640 is definitely more than 15).

Because of the way the math works, you may as well replace the function call with the value 15728655 (and ignore all lighting). Which you could then divide and modulo by 65536 yourself.

There is one problem, it ignores block lighting and uses only sky lighting.

(...wasn't that the whole point? To ignore lighting conditions?)

I didn't intend to make the overlay fully bright, but it looks cool, so I will keep it like that:

OpenGlHelper.setLightmapTextureCoords(OpenGlHelper.lightmapTexUnit, 240, 240);

Had to look at how the lightmap works, that's the reason I didn't understand it before.

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! :)

for example minecraft 1.21.8 code for the golden apple is

Foods.java
public static final FoodProperties GOLDEN_APPLE = new FoodProperties.Builder().nutrition(4).saturationModifier(1.2F).alwaysEdible().build();

Items.java
public static final Item GOLDEN_APPLE = registerItem("golden_apple", new Item.Properties().food(Foods.GOLDEN_APPLE, Consumables.GOLDEN_APPLE));

Consumables.java
