Rendering a standard block as part of a TileEntity?


Recommended Posts

So here's what I'm trying to do, I have a model that I want to render a block of flowing water in the same space so that my model doesn't need to supply the faces and texture of flowing water itself for various reasons.

 

public class TESRSluiceBottom extends TileEntitySpecialRenderer {
private ModelSluice sluice = new ModelSluice();

@Override
public void renderTileEntityAt(TileEntity tileentity, double d0, double d1, double d2, float f) {
	System.out.println("Rendering sluice at " + tileentity.xCoord + "," + tileentity.yCoord + "," + tileentity.zCoord);
	System.out.println("world: " + RenderBlocks.getInstance().blockAccess);
	if(RenderBlocks.getInstance().blockAccess != null) {
		RenderBlocks.getInstance().renderBlockAllFaces(Blocks.flowing_water, tileentity.xCoord, tileentity.yCoord, tileentity.zCoord);
	}
	sluice.render(tileentity, d0, d1, d2, 0, ((TileEntitySluiceBottom)tileentity).getRotationY());
}

public void renderTileEntityInventory(TileEntity tileentity, double d0, double d1, double d2, float f) {
	sluice.render(tileentity, d0, d1, d2, 0, f);
}
}

 

Problem is:

RenderBlocks.getInstance().blockAccess is always null.

 

Rendering sluice at -720,62,-447
world: null
Rendering sluice at -720,62,-447
world: null
Rendering sluice at -720,62,-447
world: null
Rendering sluice at -720,62,-447
world: null
Rendering sluice at -720,62,-447
world: null
Rendering sluice at -720,62,-447
world: null
Rendering sluice at -720,62,-447
world: null

 

If that IBlockAccess field is null, then when it goes to attempt to render the water, it tries to get the biome color to use for the water, which requires a non-null world (i.e. it crashes).

 

So clearly I'm doing something wrong somewhere.  What do I need to change?

RenderBlocks.getInstance() is a global, singleton-like instance added by Forge. It has no world by default, you need to set it before you render and unset it afterwards.

 

Ahh.  I'll try that, thanks.

Hmm.  It didn't crash, but it also didn't render the water.

Item Render is using an old model which is not being used in-world at all (commented sluice.render(...) so it would just draw the water).  Not sure how to go about debugging that, as it would require adding statements inside vanilla code.

Thanks anyway Diesieben.  Trying to poke at the values that make RenderBlock do its Thing, nothing is seeming to indicate a complete non-render. :\

 

Copying tessellator code now to do it my bloody self.

Long story short:

 

For some reason the tessellator doesn't work when called from a TESR.

Same code copied into an ISimpleBlockRenderer renders just fine.
