[1.7.2] Block rotation

Posted April 21, 201411 yr

I have a block with a custom model and I have all the code setup so that it renders correctly and the same "front" face points towards the player, depending on from which direction the player places the block (e.g. rotates like a furnace). However, once I exit the world and reload it, the block automatically rotates back to standard position (facing south), instead of staying in the orientation it has been set to. Anyone know what the issue is? I think it has something to do with the NBT data, but i'm not sure why.

CODE:

Block:

package lifemod.blocks.toilet;

import lifemod.LifeMod;
import lifemod.lifepanel.LifePanel;
import net.minecraft.block.BlockContainer;
import net.minecraft.block.material.Material;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.ItemStack;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.util.MathHelper;
import net.minecraft.world.World;

public class BlockToilet extends BlockContainer
{
public BlockToilet()
{
	super(Material.rock);
	this.setBlockBounds(0.0F, 0.0F, 0.0F, 1.0F, 1.0F, 1.0F);
}

@Override
public TileEntity createNewTileEntity(World var1, int var2)
{
	return new TileEntityToilet(); 
}

    public int getRenderType()
    {
    	return -1;
    }
    
    public boolean isOpaqueCube()
    {
    	return false;
    }

    public boolean renderAsNormalBlock()
    {
    	return false;
    }
    
    @Override
    public void onBlockPlacedBy(World world, int i, int j, int k, EntityLivingBase entityliving, ItemStack itemStack)
    {
        int facing = MathHelper.floor_double((double) ((entityliving.rotationYaw * 4F) / 360F) + 0.5D) & 3;
        int newFacing = 0;
        if (facing == 0)
        {
        	newFacing = 2;
        }
        if (facing == 1)
        {
        	newFacing = 5;
        }
        if (facing == 2)
        {
        	newFacing = 3;
        }
        if (facing == 3)
        {
        	newFacing = 4;
        }
        TileEntity te = world.getTileEntity(i, j, k);
        if (te != null && te instanceof TileEntityToilet)
        {
        	TileEntityToilet tet = (TileEntityToilet) te;
            tet.setFacingDirection(newFacing);
            world.markBlockForUpdate(i, j, k);
        }
    }
}

TileEntity

package lifemod.blocks.toilet;

import lifemod.packethandler.PacketHandler;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.network.Packet;
import net.minecraft.tileentity.TileEntity;

public class TileEntityToilet extends TileEntity
{
private int facingDirection;

public int getFacingDirection()
    {
        return this.facingDirection;
    }

public void setFacingDirection(int par1)
    {
        this.facingDirection = par1;
    }

@Override
    public void readFromNBT(NBTTagCompound nbttagcompound)
    {
        super.readFromNBT(nbttagcompound);  
        facingDirection = nbttagcompound.getInteger("facingDirection");
    }

    @Override
    public void writeToNBT(NBTTagCompound nbttagcompound)
    {
        super.writeToNBT(nbttagcompound);
        nbttagcompound.setInteger("facingDirection", facingDirection);
    }
}

TileEntitySpecialRenderer:

    {
    	GL11.glPushMatrix(); 	
        GL11.glTranslatef((float) x + 0.5F, (float) y + 1.5F, (float) z + 0.5F);
        this.bindTexture(texture);
        //Rotates model, as for some reason it is initially upside (180 = angle, 1.0F at end = about z axis)
        GL11.glRotatef(180, 0.0F, 0.0F, 1.0F);
        int facing = te.getFacingDirection();
        int k = 0;
        //South
        if (facing == 2) {
            k = 0;
        }
        //North
        if (facing == 3) {
            k = 180;
        }
        //East
        if (facing == 4) {
            k = -90;
        }
        //West
        if (facing == 5) {
            k = 90;
        }
        //Rotates model on the spot, depending on direction, making the front always to player) (k = angle, 1.0F in middle = about y axis)
        GL11.glRotatef(k, 0.0F, 1.0F, 0.0F);
        GL11.glDisable(GL11.GL_CULL_FACE);
        GL11.glEnable(GL11.GL_ALPHA_TEST);
        this.model.render((Entity)null, 0.0F, 0.0F, -0.1F, 0.0F, 0.0F, 0.0625F);
        GL11.glPopMatrix();
}

    
    public void renderTileEntityAt(TileEntity p_147500_1_, double p_147500_2_, double p_147500_4_, double p_147500_6_, float p_147500_8_)
    {
    	this.render((TileEntityToilet)p_147500_1_, p_147500_2_, p_147500_4_, p_147500_6_, p_147500_8_);
    }
}

Inside the ClientProxy:

ClientRegistry.bindTileEntitySpecialRenderer(TileEntityToilet.class, new TileEntitySpecialRendererToilet());

Thanks in advance

First have you registered you tileentity? If you have add this to the tileentity code:

   @Override
    public Packet getDescriptionPacket()
    {
        NBTTagCompound tag = new NBTTagCompound();
        writeToNBT(tag);
        return new S35PacketUpdateTileEntity(xCoord, yCoord, zCoord, 1, tag);
    }

    @Override
    public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity packet)
    {
        readFromNBT(packet.func_148857_g());
    }

My mod for futher awesomeness:

As soon as I placed the block in the world this crash report appeared and the game crashed:

Yep that is an unregistred tileentity! You need to add this in your common proxy:

GameRegistry.registerTileEntity(MyTileEntity.class, "MyTileEntityName");

I recommend in your proxy have a method called registerTileEntities().

ClientProxy:

@Override
public static void registerTileEntities()
{
    super.registerTileEntities();
    ClientRegistry.bindTileEntitySpecialRenderer(TileEntityToilet.class, new TileEntitySpecialRendererToilet());
}

CommonProxy:

public static void registerTileEntities()
{
    GameRegistry.registerTileEntity(TileEntityToilet.class, "Toilet");
}

And in your mod class in preInit add this:

proxy.registerTileEntities();

My mod for futher awesomeness:

I had it registered anyway. But, now it works so thank you

Yeah I saw, he just mentioned Fabric so I was wondering when it would be out.
@FoxyWoxy
When you are near (1-12ish blocks) the stab shot when it hits, the player gets launched around 50-100 blocks in the air

Thanks for your feedback and suggestions. The new forums run Invision Community 5 - some things are more customisable, other things a lot less. I'm happy to adjust the settings as desired but not sure where they'd be or if they're still available in the new version, so if you could let me know I'll give it a go.
