[SOLVED] Tessellator - already tessellating error

Enkey · November 28, 2013

Hi,

I wanted to play around with tesselator, but I got this error:

Hi

The caller has already performed tes.startDrawingQuads(); for you. Delete that line and it should be fine.

You can't do two startDrawingXXX in a row without a draw between them (and vica versa too)

Well I was thinking about it too, but guess what... then I get "Not tesselating!" error

Do not call tess.draw() either.

Do not call tess.draw() either.

I tried that too, but then it screws up the wohle chunk where I place the block:

At least it's not crashing (I am probably doing something else wrong?)

Hi

Well we're making progress...

I didn't have this problem in my own ISBRH renderers so far, but perhaps you need to undo some of the setting changes you are making (setTranslate, texture, etc).

I'd suggest removing them one by one and seeing which one(s) are causing the weirdness.

And come to think of it, I don't think you need setTranslate, the caller should have done that for you. Setting it to 0,0,0 might actually be causing your problem.

Something else to be aware of - if your block has transparent bits (is not a full, opaque cube), you need to override isOpaqueBlock to return false.

Ok so binding the texture was the problem. So how do I tell the tessellator which texture to use?

I know that

Hi

From looking in EntityRenderer.renderWorld I think this should work:

Minecraft.getMinecraft().getTextureManager().bindTexture(TextureMap.locationBlocksTexture);

Hi

Minecraft.getMinecraft().getTextureManager().bindTexture(TextureMap.locationBlocksTexture);

-TGG

Well it's almost the same as I did it before and this is binding the texture map for vanilla blocks (and even then there is no texture). But now I know why it was doing that glitch where blocks didn't have texture. It was because I was binding my texture, but then it using it for every block in that chunk. So I have just put Minecraft.getMinecraft().getTextureManager().bindTexture(TextureMap.locationBlocksTexture); when I finished rendering my block and it's not doing that glitch, but my block is still not rendering (or doesn't have texture)

TheGreyGhost · November 30, 2013

Hi

Sounds like it might be rendering but not in the place you expect.

Suggest to try

// comment this out		tes.setTranslation(x, y, z);

Hi

Sounds like it might be rendering but not in the place you expect.

Suggest to try

// comment this out		tes.setTranslation(x, y, z);

	ResourceLocation textures = (new ResourceLocation(Reference.modid + ":textures/models/LEDStrip.png")); 
        Minecraft.getMinecraft().renderEngine.bindTexture(textures);
        
        tes.addVertexWithUV(x,     y,     z, 0, 1);
        tes.addVertexWithUV(x, y+1,     z, 0, 0);
        tes.addVertexWithUV(x, y+1, z+1, 1, 0);
        tes.addVertexWithUV(x,     y, z+1, 1, 1);

I've already done that

Actual code:

package morelights.renderers;

import org.lwjgl.opengl.GL11;

import morelights.lib.Reference;
import morelights.proxy.ClientProxy;
import net.minecraft.block.Block;
import net.minecraft.client.Minecraft;
import net.minecraft.client.renderer.RenderBlocks;
import net.minecraft.client.renderer.Tessellator;
import net.minecraft.client.renderer.texture.TextureMap;
import net.minecraft.util.ResourceLocation;
import net.minecraft.world.IBlockAccess;
import cpw.mods.fml.client.registry.ISimpleBlockRenderingHandler;

public class LEDStripRenderer implements ISimpleBlockRenderingHandler {

@Override
public void renderInventoryBlock(Block block, int metadata, int modelID,
		RenderBlocks renderer) {

}

@Override
public boolean renderWorldBlock(IBlockAccess world, int x, int y, int z,
		Block block, int modelId, RenderBlocks renderer) {

	Tessellator tes = Tessellator.instance;
	int lightValue = block.getMixedBrightnessForBlock(world, x, y, z);
	tes.setBrightness(lightValue);
	tes.setColorOpaque_F(1.0F, 1.0F, 1.0F);

	ResourceLocation texture = (new ResourceLocation(Reference.modid + ":textures/models/LEDStrip.png"));
	Minecraft.getMinecraft().getTextureManager().bindTexture(texture);
        
        tes.addVertexWithUV(0, 0, 0, 0, 1);
        tes.addVertexWithUV(0, 1, 0, 0, 0);
        tes.addVertexWithUV(0, 1, 1, 1, 0);
        tes.addVertexWithUV(0, 0, 1, 1, 1);
        
        Minecraft.getMinecraft().getTextureManager().bindTexture(TextureMap.locationBlocksTexture);
        
	return true;
}

@Override
public boolean shouldRender3DInInventory() {
	return true;
}

@Override
public int getRenderId() {
	return ClientProxy.LEDStripRenderType;
}
}

Hi

Your code currently renders from [0,0,0] to [1,1,1] instead of from [x,y,z] to [x+1, y+1, z+1].

Did you try that [x,y,z] to [x+1, y+1, z+1] already?

I think the tes.setTranslation(x, y, z) won't work because the caller has set the viewpoint and translation relative to the chunk coordinates, not relative to an origin of [0,0,0]

Also, if you want to change the texture, you need to do it while the tesselator is not tesselating, otherwise you'll mess up rendering of other blocks. You also need to restore the previous texture when you're finished, again while the tesselator is not tesselating. The correct procedure is:

tes.draw();
/* bind your texture here */
tes.startDrawingQuads();
/* draw your block here */
test.draw();
/* restore the default texture */
tes.startDrawingQuads();

But note that using a custom texture for rendering blocks is no longer the recommended way of doing things. The modern way is to provide each of your block images as a separate image file, and let MC stitch them into the main texture. This eliminates the need to switch textures while rendering blocks, simplifying your rendering code and improving graphics performance.

To see how it's done, take a look at the

registerIcons()

method of some of the vanilla blocks, and how RenderBlocks makes use of the

Icon

class.

Thanks! I didn't know it works like that

EDIT: Can I rename the topic? If not, can someone rename it to [sOLVED] ?
