[1.8.8] How to render a block with a TESR by using the IBakedModel of another?

Geforce · November 12, 2016

Hey there,

I made a block with a TileEntitySpecialRenderer, and I want to have it rendered as whatever block is inserted into the TESR block's GUI. I'm currently using the code below, just to try to at least get it working, but it always crashes with this error, also below. I'm not sure if BlockModelRenderer.renderModel() is the correct method I'm supposed to be using here, and if I'm supposed to be using the GL methods as well (eg: pullMatrix(), popMatrix(), etc)? Could someone clear this up for me?

Thanks!

Code:

// Simplified code here, so it's easier to understand on the forums

public void renderTileEntityAt(TileEntity tileEntity, double x, double y, double z, float f, int number){

BlockPos pos = tileEntity.getPos();

IBakedModel model = Minecraft.getMinecraft().getRenderItem().getItemModelMesher().getItemModel(block);

WorldRenderer renderer = Tessellator.getInstance().getWorldRenderer();

Minecraft.getMinecraft().getBlockRendererDispatcher().getBlockModelRenderer().renderModel(tileEntity.getWorld(), model, tileEntity.getWorld().getBlockState(pos), pos, renderer);

Crash:

Why a TESR?

Well, I was trying to render it dynamically at first, by using vertexes, WorldRenderer, and the Tessellator to draw the texture of a block. But then I noticed that I had the IBakedModel of the Block I wanted to render as, so I thought that would be easier to use, especially if the block used multiple textures (furnace, grass, etc.). If there is an easier way to accomplish the same thing without using a TESR, please let me know.

I have an example here. It renders a floating ball that spins, and bobs up and down.

Do note, it is for 1.10. VertexBuffer is the equivalent of 1.8's WorldRenderer here.

Ah, thanks, that's exactly what I've been looking for! I used some of your code to finish up my TESR.

The only thing is that I'm still getting the same crash as before, do you know what's wrong?

Code:

private IBakedModel blockModel;

public void renderTileEntityAt(TileEntity tileEntity, double x, double y, double z, float f, int number){

if(((TileEntityKeypad) tileEntity).hasModule(EnumCustomModules.DISGUISE)) {

ItemModule module = (ItemModule) ((TileEntityKeypad) tileEntity).getModule(EnumCustomModules.DISGUISE).getItem();

blockModel = getBlockModel(module.getBlockAddons(((TileEntityKeypad) tileEntity).getModule(EnumCustomModules.DISGUISE).getTagCompound()).get(0));

}

else {

blockModel = getBlockModel(mod_SecurityCraft.keypad);

}

GlStateManager.pushAttrib();

GlStateManager.pushMatrix();

RenderHelper.disableStandardItemLighting();

GlStateManager.enableBlend();

GL11.glBlendFunc(GL11.GL_ONE, GL11.GL_ONE_MINUS_DST_COLOR);

GlStateManager.translate(x, y, z);

WorldRenderer wr = Tessellator.getInstance().getWorldRenderer();

wr.startDrawingQuads();

Minecraft.getMinecraft().getBlockRendererDispatcher().getBlockModelRenderer().renderModel(tileEntity.getWorld(), blockModel, tileEntity.getWorld().getBlockState(tileEntity.getPos()), tileEntity.getPos(), wr, false);

Tessellator.getInstance().draw();

GlStateManager.disableBlend();

RenderHelper.enableStandardItemLighting();

GlStateManager.popMatrix();

GlStateManager.popAttrib();

}

private IBakedModel getBlockModel(Block blockToRenderAs) {

if(blockModel == null) {

return Minecraft.getMinecraft().getRenderItem().getItemModelMesher().getItemModel(new ItemStack(blockToRenderAs));

}

return blockModel;
