Render custom model as a tile entity

Start new topic

Posted June 12, 201312 yr

Hey guys,

I'm trying to make a tile entity with a custom model. However, in-game I just get a standard block with "Missing Texture", and this spammed in the console:

2013-06-12 21:45:50 [sEVERE] [Minecraft-Client] ########## GL ERROR ##########
2013-06-12 21:45:50 [sEVERE] [Minecraft-Client] @ Post render
2013-06-12 21:45:50 [sEVERE] [Minecraft-Client] 1283: Stack overflow

Anyone got any ideas?

My TileEntitySpecialRenderer class:

Let me know if you need to see other classes.

I've fixed the above, but a new issue now. The block simply isn't rendering... just an empty bounding box!

My code (updated)

package co.uk.silvania.roads.tileentities;

import org.lwjgl.opengl.GL11;

import co.uk.silvania.roads.Roads;
import co.uk.silvania.roads.client.TrafficLightModel;

import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.IBlockAccess;
import net.minecraft.world.World;

public class TileEntityTrafficLightRenderer extends TileEntitySpecialRenderer {

TrafficLightModel model;

public TileEntityTrafficLightRenderer() {
	model = new TrafficLightModel();
}

@Override
public void renderTileEntityAt(TileEntity tileentity, double d, double d1, double d2, float f) {

	GL11.glPushMatrix();

	GL11.glTranslatef((float)d, (float)d1, (float)d2);
	TileEntity te = (TileEntityTrafficLightEntity)tileentity;

	renderBlock(te, tileentity.worldObj, tileentity.xCoord, tileentity.yCoord, tileentity.zCoord, Roads.trafficLight);
	GL11.glPopMatrix();
}

public void renderBlock(TileEntity te, World world, int i, int j, int k, Block block) {

	Tessellator tessellator = Tessellator.instance;

	float f = block.getBlockBrightness(world, i, j, k);
	int l = world.getLightBrightnessForSkyBlocks(i, j, k, 0);
	int l1 = l % 65536;
	int l2 = l / 65536;
	tessellator.setColorOpaque_F(f, f, f);
	OpenGlHelper.setLightmapTextureCoords(OpenGlHelper.lightmapTexUnit, (float)l1, (float)l2);

	int dir = world.getBlockMetadata(i, j, k);

	GL11.glPushMatrix();
	GL11.glTranslatef(0.5F, 0F, 0.5F);
	GL11.glRotatef(dir * (-90F), 0F, 1F, 0F);
	GL11.glTranslatef(-0.5F, 0F, -0.5F);
	bindTextureByName("/mods/roads/textures/blocks/TrafficLightPoleRed.png");
	GL11.glPopMatrix();
}

You....are not doing things the way I'm doing them, and it does not appear that your....renderer has any quads or a model to draw.

Here's mine:

private SpikesModel spikes = new SpikesModel();

@Override
public void renderTileEntityAt(TileEntity tileentity, double d0, double d1, double d2, float f) {
	spikes.render(tileentity, d0, d1, d2);
}
}

Model was exported from Techne and minorly tweaked.*

*Imports and oddly, the model came in upside down and I had to figure out how to flip it back over.

I've been getting some help on #MinecraftForgeTuts, and mine does import now but always with some sort of render bug.

It's usually upside down, but I've got it tweaked so it's been inside the player, moving around depending on the players position, or even inside-out. I can't get it to go the right way up, and stay there.

What did you do to fix it?

Here's my current code:

package co.uk.silvania.roads.tileentities;

import org.lwjgl.opengl.GL11;


import co.uk.silvania.roads.Roads;
import co.uk.silvania.roads.client.TrafficLightModel;

import cpw.mods.fml.client.registry.ISimpleBlockRenderingHandler;

import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.IBlockAccess;
import net.minecraft.world.World;


public class TileEntityTrafficLightRenderer extends TileEntitySpecialRenderer {

private final TrafficLightModel model;

public TileEntityTrafficLightRenderer() {
	this.model = new TrafficLightModel();
}

@Override
public void renderTileEntityAt(TileEntity te, double x, double y, double z, float scale) {
	GL11.glPushMatrix();
	GL11.glTranslatef((float) x + 0.5F, (float) y + 1.5F, (float) z + 0.5F);
	bindTextureByName("/mods/roads/textures/blocks/TrafficLightPoleRed.png");
	this.model.render((Entity)null, 0.0F, 0.0F, -0.1F, 0.0F, 0.0F, 0.0625F);
	GL11.glPopMatrix();
}

private void adjustRotatePivotViaMeta(World world, int x, int y, int z) {
	int meta = world.getBlockMetadata(x, y, z);
	GL11.glRotatef(meta * (90), 0.0F, 1.0F, 0.0F);
}

private void adjustLightFixture(World world, int i, int j, int k, Block block) {
	Tessellator tess = Tessellator.instance;
	float brightness = block.getBlockBrightness(world, i, j, k);
	int skyLight = world.getLightBrightnessForSkyBlocks(i, j, k, 0);
	int modulousModifier = skyLight % 65536;
	int divModifier = skyLight / 65536;
	tess.setColorOpaque_F(brightness, brightness, brightness);
	OpenGlHelper.setLightmapTextureCoords(OpenGlHelper.lightmapTexUnit,  (float) modulousModifier,  divModifier);
}

I went in and rotated each cube of my model in the model code and repositioned them by hand. Not the easiest or most elegant way to do it, but it worked.

And if you think rendering it inside the player is weird, try this:

That's certainly... interesting.

Anyways, figured it out now. Here's the working code:

Hello -

How did you get you model to start rendering? Using the code on the wiki doesn't work, and I've tried many, many threads that I've discovered on the internet through searching (all to no avail).

I'm on my phone ATM sorry

If you go on google and search FlenixRoads one of the first results is my GitHub repo.

In there, you need to find my Tileentities package. Pick one of the block names (TileEntityTrafficLight is a good example) and copy the block, entity and renderer classes.

Then go to my client package and get TrafficLightModel (just for now). Also look in the client proxy and copy the one line for the traffic light.

After that just do registerblock as normal for TileEntityTrafficLightBlock. Test it and all should be working, so then you can edit it as required.

Ill write a wiki on it when I'm home

Thanks.

I went and looked at your code. I changed some of what I had to more closely match yours and I still just get an empty bounding box. I even tried using your model and got nothing.

June 14, 201312 yr

I GOT IT TO RENDER! (sorry for caps, very exciting!)

I just changed my block to extend BlockContainer instead of Block, and it works!

Thank you so much!

Please write the wiki page too, because I'm sure there are lots of people still trying to get this correct for the new versions.

That's a lot more important than you think it is

I'll write the wiki when I've got a few hours free, so it'll be sunday or monday. It's one of those things that's really underdocumented (same as liquids which I wrote the 1.4.7 wiki page on... I should update that...)

As we've both got it working I'll lock this now. Anyone else who gets stuck can use my code as mentioned above, or PM me
