[1.5.2] TileEntity problems.

[DoorCloser]

Hey guys. Last time i visited this page i was a little bit rude to you guys. Sorry for that though. But now i have some more questions and problems in coding My TileEntity spawns ok, but always faced in one direction. How to make it faced to me always i put it.  I tried to put that code in my BlockName file:

public void onBlockPlacedBy(World par1World, int par2, int par3, int par4, EntityLiving par5EntityLiving, ItemStack par6ItemStack)
    {
        int var7 = MathHelper.floor_double((double)(par5EntityLiving.rotationYaw * 4.0F / 360.0F) + 2.5D) & 3;
        par1World.setBlockMetadataWithNotify(par2, par3, par4, var7, 2);
    }

 

So my TileEntity still spawns faced in one direction, but i think i know what the problem. Block have no Textures so i dont see it changes it's facing direction. TileEntity doesnt rotate because i have to do something in TileEntity file, i guess? Could anybody help?

Or your TileEntitySpecialRenderer, if you're using one.

Indeed, rotation doesn't have anything to do with the TileEntity, it's stored in metadata.

In your

getIcon

method in your Block you have to return the appropriate texture for the given side and metadata, where metadata represents the rotation.

Look at the furnace for an example.

 

That what you mean?

 

public Icon getIcon(int par1, int par2)
    {
        return par1 == 1 ? this.furnaceIconTop : (par1 == 0 ? this.furnaceIconTop : (par1 != par2 ? this.blockIcon : this.furnaceIconFront));
    }

 

 

My TileEntity Actually looks like this.

If i put that code for top, side, bottom and etc textures, it will sit correctly?

Yes, i have that extending in my TileEntityNameRenderer file. I have to do something different?

So if i use TileEntitySpecialRenderer extended in my TileEntityNameRenderer, then what i suppose to type and where? thx

You probably have to rotate your model with

glRotate

.

GL11.glRotatef(meta * (-90), 0.0F, 0.0F, 1.0F);

You mean this? I already had this. Not a solution...

Then either:

 

a) meta isn't getting set correctly

b) meta is getting 0'd somewhere

c) you aren't reading the meta correctly

EDIT: I noticed that you're asking about 1.5.2; I'll look into it ASAP.

EDIT 2: 1.5.2 won't decompile for me...

You need to tweak fml.py to have different URLs.

 

Here's my fml.py that worked for Forge 871 (its basically the same as the last non-gradle 1.6.4) so it should work for you.

EDIT: I noticed that you're asking about 1.5.2; I'll look into it ASAP.

EDIT 2: 1.5.2 won't decompile for me...

 

So, it decompiled? Can you help me?

Since Forge 1.5.2 wouldn't work, I had to use MCP. The code in

BlockFurnace

that relates to your problem is pretty much the same in 1.6.4, but try putting this code in your block class:

    /**
     * Called whenever the block is added into the world. Args: world, x, y, z
     */
    public void onBlockAdded(World par1World, int par2, int par3, int par4)

        super.onBlockAdded(par1World, par2, par3, par4);
        this.setDefaultDirection(par1World, par2, par3, par4);
    }

    /**
     * set a blocks direction
     */
    private void setDefaultDirection(World par1World, int par2, int par3, int par4)
    {
        if (!par1World.isRemote)
        {
            int var5 = par1World.getBlockId(par2, par3, par4 - 1);
            int var6 = par1World.getBlockId(par2, par3, par4 + 1);
            int var7 = par1World.getBlockId(par2 - 1, par3, par4);
            int var8 = par1World.getBlockId(par2 + 1, par3, par4);
            byte var9 = 3;

            if (Block.opaqueCubeLookup[var5] && !Block.opaqueCubeLookup[var6])
            {
                var9 = 3;
            }

            if (Block.opaqueCubeLookup[var6] && !Block.opaqueCubeLookup[var5])
            {
                var9 = 2;
            }

            if (Block.opaqueCubeLookup[var7] && !Block.opaqueCubeLookup[var8])
            {

            }

            if (Block.opaqueCubeLookup[var8] && !Block.opaqueCubeLookup[var7])
            {
                var9 = 4;
            }

            par1World.setBlockMetadataWithNotify(par2, par3, par4, var9, 2);
        }
    }

        }

Nope. Still spawning in one direction.

Then either:

 

a) meta isn't getting set correctly

b) meta is getting 0'd somewhere

c) you aren't reading the meta correctly
