Rendering a set of AxisAlignedBB with textures with TESR

[Lenardjee]

Hey guys,

 

I am fairly new to modding and at the moment, I am trying to make the 'chisel and bits' mod, as kind of a challenge. So, I have done quite a lot already, what I now need to do is render every part of the chiseled block with the correct texture. the problem is that I have no idea what the best way is to render blocks, with the only information being the AxisAlignedBB's and the textures for each component of the block. I thought a TESR would be a good idea, so this is my TESR class as far as it is now in which I just tried to render a model which wasn't registered yet:
 

package com.extraBlocks.block.miniBlock;

import java.util.List;

import org.lwjgl.opengl.GL11;

import com.extraBlocks.Main;
import com.extraBlocks.item.ModItems;

import net.minecraft.block.state.IBlockState;
import net.minecraft.client.Minecraft;
import net.minecraft.client.renderer.BlockRendererDispatcher;
import net.minecraft.client.renderer.GlStateManager;
import net.minecraft.client.renderer.RenderHelper;
import net.minecraft.client.renderer.Tessellator;
import net.minecraft.client.renderer.block.model.BakedQuad;
import net.minecraft.client.renderer.block.model.IBakedModel;
import net.minecraft.client.renderer.block.model.ItemOverrideList;
import net.minecraft.client.renderer.block.model.ModelManager;
import net.minecraft.client.renderer.block.model.ModelResourceLocation;
import net.minecraft.client.renderer.texture.TextureAtlasSprite;
import net.minecraft.client.renderer.texture.TextureMap;
import net.minecraft.client.renderer.tileentity.TileEntitySpecialRenderer;
import net.minecraft.item.ItemStack;
import net.minecraft.util.EnumFacing;
import net.minecraft.util.ResourceLocation;
import net.minecraftforge.client.model.IModel;
import net.minecraftforge.client.model.ModelLoader;
import net.minecraftforge.client.model.ModelLoaderRegistry;

public class TESRMiniBlock extends TileEntitySpecialRenderer<TileEntityMiniBlock> {

	TileEntityMiniBlock te = null;

	@Override
	public void render(TileEntityMiniBlock te, double x, double y, double z, float partialTicks, int destroyStage, float alpha) {
		renderBlock(te, x, y, z, partialTicks, destroyStage, alpha);
	}

	public void renderBlock(TileEntityMiniBlock te1, double x, double y, double z, float partialTicks, int destroyStage, float alpha) {
		te = (TileEntityMiniBlock) Minecraft.getMinecraft().getIntegratedServer().getWorld(Minecraft.getMinecraft().world.provider.getDimension()).getTileEntity(te1.getPos());

		ItemStack stack = te.inventory.getStackInSlot(0);
		if (!stack.isEmpty()) {
			BlockRendererDispatcher r = Minecraft.getMinecraft().getBlockRendererDispatcher();
			Tessellator tes = Tessellator.getInstance();

			GlStateManager.enableRescaleNormal();
			GlStateManager.alphaFunc(GL11.GL_GREATER, 0.1f);
			GlStateManager.enableBlend();
			RenderHelper.enableStandardItemLighting();
			GlStateManager.tryBlendFuncSeparate(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA, 1, 0);
			GlStateManager.translate(x + 0.5, y + 0.5, z + 0.5);
			
			IBakedModel model0 = null;
			try {
//				model0 = ModelLoaderRegistry.getModel(new ResourceLocation(Main.MODID, "block/tinyblock"));
				model0 = r.getBlockModelShapes().getModelManager().getModel(new ModelResourceLocation(Main.MODID + ":blocks/shadow_ore", "normal"));
			} catch (Exception e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
			
			if(model0 != null) {
				r.getBlockModelRenderer().renderModelBrightnessColor(model0, 1.0F, 1.0F, 1.0F, 1.0F);
			}
			
			Minecraft.getMinecraft().getTextureManager().bindTexture(TextureMap.LOCATION_BLOCKS_TEXTURE);
			Minecraft.getMinecraft().getRenderItem().renderItem(stack, model0);
			GlStateManager.disableRescaleNormal();
			GlStateManager.disableBlend();
		}
	}
}

Now, as you can probably tell, I don't quit know how to do this, so any help is greatly appreciated.

No, it's a really big challenge.
 

I've tried that concept as well in Minecraft 1.6.4, also using a TESR. Every time the Block was in view, there would be massive FPS drops because it had to render 16*16*16=4096 cubes. Using an IBakedModel (ISBRH back then) would cause massive FPS drops every time the block got updated.

 

AlgorithmX2 has done a lot of optimalizations to make it able to render without any major FPS issues, including coremodding.

 

You should try doing something more simple first. This idea might seem simple, but it it's really hard to implement in a usable way.

I know that it is a big project, but I have done all the hard work already. I have everything set up to make the parts of the block using AxisAlignedBB's and the only thing I have left to do is to display the block. The problem is: I don't know how to use IBakedModel (neither do I know if I should even be using it). And:

does that mean that using IBakedModel for this is not a problem now?

 

Furthermore, how do I update the block model while the game is running? How would that work without having to reload the texturepacks everytime I make a change to the model?

 

I can do make mods of some types, but there are parts in forge modding that I just don't quite get yet.
