Model randomly vanishes depending on where I look..

Hey guys,

 

 

I'm adding my blocks to the game as TileEntities. However, when I look around, the blocks randomly disappear if I look in certain directions...

When they disappear, the bounding box vanishes too, so I can walk through it (if I stand on the block and look around, I'll just fall down when it vanishes)

 

Screenshots:

There's three blocks you can see here:

Then I look slightly to the left, and the right one vanishes!

Code:

Block:

public class TileEntityBarrierBlock extends BlockContainer {

public TileEntityBarrierBlock(int id) {
	super(id, Material.iron);
	this.setCreativeTab(Roads.tabRoads);
}

@Override
public TileEntity createNewTileEntity(World world) {
	return new TileEntityBarrierEntity();
}

@Override

	return -1;
}

	return false;
}

	return false;
}

	this.blockIcon = icon.registerIcon("Roads:CementBlock");
}

@Override

	int var6 = MathHelper
			.floor_double(par5EntityLiving.rotationYaw * 4.0F / 360.0F + 0.5D) & 3;

	if (var6 == 0) {

	}

	if (var6 == 1) {

	}

	if (var6 == 3) {
		par1World.setBlockMetadataWithNotify(par2, par3, par4, 4, 0);
	}
}

    public void setBlockBoundsBasedOnState(IBlockAccess world, int x, int y, int z) {
    	int meta = world.getBlockMetadata(x, y, z);
    	if ((meta) == 3)
    		setBlockBounds(0.0F, 0.25F, 0.875F, 1.0F, 0.75F, 1.0F);
    	else if ((meta) == 5)
            setBlockBounds(0.875F, 0.25F, 0.0F, 1.0F, 0.75F, 1.0F);
    	else if ((meta) == 2)
    		setBlockBounds(0.0F, 0.25F, 0.0F, 1.0F, 0.75F, 0.125F);
    	else
    		setBlockBounds(0.0F, 0.25F, 0.0F, 0.125F, 0.75F, 1.0F);
    }

}

 

 

 

Renderer:

	this.model = new BarrierModel();
}


@Override

	int i = te.getBlockMetadata();
	int j = 180;

	if (i == 3) {

	}

	if (i == 5) {

	}

	if (i == 2) {

	}

	GL11.glPushMatrix();
	GL11.glTranslatef((float) x + 0.5F, (float) y + 1.5F, (float) z + 0.5F);
	GL11.glRotatef(j, 0.0F, 1.0F, 0.0F);
	GL11.glScalef(1.0F, -1F, -1F);
	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.glPushMatrix();
	GL11.glRotatef(meta, 0.0F, 0.0F, 1.0F);

	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);
}
}

 

 

The TileEntity is empty at the moment.

 

Any ideas?

 

 

Someone also told me to try using "GL11.glRotatef(((TileEntityBarrierEntity)tile).getRotationPivot()), 0.0F, 1.0F, 0.0F);" instead of the if statements I have for rotation, but they didn't go as far as to telling me how to use getRotationPivot so right now, that's useless for me. At any rate, removing the rotation code altogether doesn't fix the issue.

It's disappearing because your bounding box is outside the field of vision. Expand it to take up the whole entity (here is a helpful post.)

 

It's not at all O.o I spent a bit of time lining up the bounding boxes perfectly with the models; It's the exact right size, so that can't be the issue or I'd never notice it...

Oh. Okay then. I have no idea.

 

Unless perhaps the bounding box is in the wrong place? But if you can bump into it, then I'm out of ideas.

It may well be something in the bounding box actually.

 

I'd only tested it with the eclipse testing environment. I just compiled it all and put it in a real forge environment, and the vanishing bug stopped.

BUT, the bounding boxes are bugging out at the same time. When I look at them the black lines are in the right place, but if I move into the full block area, my character glitches out. Did you play minecraft in alpha/early beta? Remember when you jumped on a fence and it bugged? Same kind of thing.

 

 

Any ideas?

I believe, dont quote me on this, but it to do with the origin block placement of the tile entity, Thaumcraft has the issue with its scribing tools and i dont think it can be helped. The issue is when minecraft looks dfor blocks in view to render the origin block of the tile entity is not on the screen hence it srops rendering.

 

(this could be a load of rubbish but after looking through that is what i've found.)

I think a way to solve that is to modify the collision boxes, just like you did with the bounding boxes. There's a method in the block class that you can put in your block class,  but it's very messy.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

    • I have a problem, I am trying to put two different effects to two different armors but when I run it only the emerald armor effect works. This is the code public class ModArmorItem extends ArmorItem{ private static final Map<ArmorMaterial, MobEffectInstance> MATERIAL_TO_EFFECT_MAP = (new ImmutableMap.Builder<ArmorMaterial, MobEffectInstance>()) .put(ModArmorMaterials.EMERALD, new MobEffectInstance(MobEffects.HERO_OF_THE_VILLAGE,200, 1,false,false, true)) .put(ModArmorMaterials.OBSIDIAN, new MobEffectInstance(MobEffects.FIRE_RESISTANCE,200, 1,false,false, true)).build(); public ModArmorItem(ArmorMaterial pMaterial, Type pType, Properties pProperties) { super(pMaterial, pType, pProperties); } @Override public void onArmorTick(ItemStack stack, Level world, Player player){ if (!world.isClientSide()) { if (hasFullSuitOfArmorOn(player)) { evaluateArmorEffects(player); } } } private void evaluateArmorEffects(Player player) { for (Map.Entry<ArmorMaterial,MobEffectInstance> entry : MATERIAL_TO_EFFECT_MAP.entrySet()){ ArmorMaterial mapArmorMaterial = entry.getKey(); MobEffectInstance mapStatusEffect = entry.getValue(); if (hasCorrectArmorOn(mapArmorMaterial, player)) { addStatusEffectForMaterial(player, mapArmorMaterial, mapStatusEffect); } } } private void addStatusEffectForMaterial(Player player, ArmorMaterial mapArmorMaterial, MobEffectInstance mapStatusEffect) { boolean hasPlayerEffect = player.hasEffect(mapStatusEffect.getEffect()); if (hasCorrectArmorOn(mapArmorMaterial, player) && !hasPlayerEffect) { player.addEffect(new MobEffectInstance(mapStatusEffect)); } } private boolean hasCorrectArmorOn(ArmorMaterial material, Player player) { for (ItemStack armorStack : player.getInventory().armor){ if (!(armorStack.getItem() instanceof ArmorItem)) { return false; } } ArmorItem helmet = ((ArmorItem)player.getInventory().getArmor(3).getItem()); ArmorItem breastplace = ((ArmorItem)player.getInventory().getArmor(2).getItem()); ArmorItem leggins = ((ArmorItem)player.getInventory().getArmor(1).getItem()); ArmorItem boots = ((ArmorItem)player.getInventory().getArmor(0).getItem()); return helmet.getMaterial() == material && breastplace.getMaterial() == material && leggins.getMaterial() == material && boots.getMaterial() == material; } private boolean hasFullSuitOfArmorOn(Player player){ ItemStack helmet = player.getInventory().getArmor(3); ItemStack breastplace = player.getInventory().getArmor(2); ItemStack leggins = player.getInventory().getArmor(1); ItemStack boots = player.getInventory().getArmor(0); return !helmet.isEmpty() && !breastplace.isEmpty() && !leggins.isEmpty() && !boots.isEmpty(); } } Also when I place two effects on the same armor, the game crashes. Here is the crash file. The code is the same, only this part is different   private static final Map<ArmorMaterial, MobEffectInstance> MATERIAL_TO_EFFECT_MAP = (new ImmutableMap.Builder<ArmorMaterial, MobEffectInstance>()) .put(ModArmorMaterials.EMERALD, new MobEffectInstance(MobEffects.HERO_OF_THE_VILLAGE,200, 1,false,false, true)) .put(ModArmorMaterials.EMERALD, new MobEffectInstance(MobEffects.FIRE_RESISTANCE,200, 1,false,false, true)).build(); I hope you guys can help me. Thanks.
    • I removed all related embeddium and oculus mods, i just tested it by disconnecting and the error happened again. heres the report https://pastebin.com/1kcR5wAt   EDIT: i tried removing xaeros and also smoothboot thinking there may be an issue there, nothing, heres that report too. https://pastebin.com/zQS7i9rM
    • Hi, I need suggestions. I am a beginner in Minecraft Modding. I would like to apply custom effects to some armors, something like: more chance to drop seeds, change zombie awareness, drop more pieces of wood when chopping logs, and things like that. How would you recommend me to do it, is there any library that has something similar and which ones would you recommend me?.
    • "downloading minecraft server failed, invalid Checksum. try again, or manually place server.jar to skip download"    
    • You have to create an Entity class called PlayerPart and use multiple of them to make the different parts of the player. See EnderDragonPart.java source code. The green hitboxes of the dragon are all EnderDragonParts
