net.minecraft.client.renderer.RenderBlocks#getBlockIconFromSideAndMetadata in 1.10.2?

[lukas2005]

hello i have this piece of code net.minecraft.client.renderer.RenderBlocks#getBlockIconFromSideAndMetadata and i cant figure out what is its equivalent in 1.10.2

[lukas2005]

im trying to port this bit of code to 1.10.2 (from 1.7.10)

                            IIcon icon = renderer.getBlockIconFromSideAndMetadata(block, 1, meta);
                            double tu0 = (double)icon.getMinUV();
                            double tu1 = (double)icon.getMaxU();
                            double tv0 = (double)icon.getMinV();
                            double tv1 = (double)icon.getMaxV();

What is your overall goal? What feature is this code a part of? We need some more context than a snippet of code.

That code alone does precisely nothing.

im using this to then be able to use tessalator to render some stuff

What "stuff"? You're being very vague, which makes it hard to help you.

i just use this little snippet for rendering an i need to know what is repacment for IIcon and RenderBlocks

But what are you trying to render? Where are you rendering it?

 

IIcon and RenderBlocks were replaced by the baked model system, but it's hard to tell you what you need to do when we don't actually know what you're trying to do.

i am trying to make terrain smoother rather than just blocks and i need to know the size of textures for tesselator

The main problem you'll run into is that blocks no longer have textures, they now have models. An IBakedModel can have any number of BakedQuads, each of which belongs to an EnumFacing (or null) and has a texture.

 

You can use IBakedModel#getQuads to get the BakedQuads for an optional IBlockState and optional EnumFacing. You'll need to work out what to do if the model has either zero or more than one BakedQuads for EnumFacing.UP (probably blacklist that state from being smoothed).

 

Look at BlockRendererDispatcher#renderBlock to see how it gets the actual state from the in-world state, the model from the actual state and the extended state from the actual state before rendering the model.

As I said, look at BlockRendererDispatcher#renderBlock.

Yes, you should use it too. Use Minecraft#getBlockRendererDispatcher to get the BlockRenderDispatcher instance.

That's a "random" number derived from the BlockPos, use MathHelper.getPositionRandom to calculate it.

Get its texture with BakedQuad#getSprite. This is a TextureAtlasSprite, a sprite on the block/item texture atlas (like IIcon).

ok i now have my sizes but there is one more thing what are these?

tess.setBrightness(block.getMixedBrightnessForBlock(Minecraft.getMinecraft().theWorld, br[0], br[1], br[2]));

tess.setColorOpaque_I(block.colorMultiplier(cache, c[0] + x[0], c[1] + x[1], c[2] + x[2]));

I can't really help you with rendering specifics like this, all I can suggest is looking at ForgeBlockModelRenderer#renderModelFlat/ForgeBlockModelRenderer#renderModelSmooth (called by BlockModelRenderer#renderModel) to see how they render block models.
