[1.14] Forge Fluid Model?

[Draco18s]

In 1.12 I had a block that used extended states in order to render flowing water over the top of its regular model. I managed this using the forge:fluid model:

https://github.com/Draco18s/ReasonableRealism/blob/1.12.1/src/main/resources/assets/harderores/blockstates/basic_sluice.json#L7

 

That model is no longer available in 1.14, so how would I go about doing this instead?

 

Currently I get this error:

Additionally, getExtendedState no longer exists and I don't see a replacement, even though the update notes mention it.

 

 

More pictures of what it looks like can be found on the mod wiki.

Forge's fluid system (including the forge:fluid model) was removed in 1.13 due to large changes in the Vanilla fluid system. Forge's new fluid system is still being worked on, you can see some of the progress in this PR and KingLemming's fork.

 

Until then, you could look at Vanilla's waterloggable blocks (IWaterLoggable) where the block can exist in the same space as a fluid (usually water).

 

Extended states were replaced by the model data system in this PR.

Already did, it is not sufficient for my needs. Waterlogged blocks can only be completely full of water ("source blocks") not flowing (as of the current version) and I specifically need flowing water (and that flow needs to "decay" twice as fast). I even attempted to return a different fluid state that contained level information, but it did not work.

Thanks.

What has world.markBlockRangeForRenderUpdate(pos, pos); been replaced by?

The closest equivalents I can see are World#func_225319_b or WorldRenderer#markBlockRangeForRenderUpdate, though a lot of places that used to call World#markBlockRangeForRenderUpdate don't seem to call anything in its place now.

func_225319_b looks like the one I want. Thanks.

Still trying to work out the other stuff, but fortunately I found an example and will just have to beat my head against it for a while.

Well, this is about as far as I can get.

 

I can't get the color/transparency right. Both the int color variable (which is set by the TE as the biome water color) and the faceData[i + 6] = 0x7F00; have an effect on what renders. Changing the 7F00 value "too much" causes the quad to become opaque, but its more of a magic bitflag thing (I can't tell which bit(s) are involved, just that some values are Fine and some values are Not Fine).

		}
	}

	private void storeVertexData(int[] faceData, int storeIndex, int vertexIndex, Vector3f position, int shadeColor, TextureAtlasSprite sprite, BlockFaceUV faceUV) {
		int i = storeIndex * 7;
		faceData[i] = Float.floatToRawIntBits(position.getX());
		faceData[i + 1] = Float.floatToRawIntBits(position.getY());
		faceData[i + 2] = Float.floatToRawIntBits(position.getZ());
		faceData[i + 3] = shadeColor;
		faceData[i + 4] = Float.floatToRawIntBits(sprite.getInterpolatedU((double)faceUV.getVertexU(vertexIndex) * .999 + faceUV.getVertexU((vertexIndex + 2) % 4) * .001));
		faceData[i + 5] = Float.floatToRawIntBits(sprite.getInterpolatedV((double)faceUV.getVertexV(vertexIndex) * .999 + faceUV.getVertexV((vertexIndex + 2) % 4) * .001));
		faceData[i + 6] = 0x7F00;
	}

 

Mainly it acts like its not taking into account light levels (at night it looks like a very pale cyan color!?),  but setting diffuseLight to false doesn't change anything.

Finally figured out what was going on.

 

I wasn't taking into account the side parameter, so all the faces I was generating were being rendered 6 times. I just didn't expect that to do that that way. Once I fixed that I figured out that the 7F00 value was affecting the transparency and was "too transparent" (despite having been the value that was returned when I told vanilla code to generate quads).

 

End result: fucking beautiful

 

Also made the wood part follow the angle, as I'd always wanted to have happen.
