Rendering animated block in 1.10

Raycoms · September 8, 2016

I'm currently porting to 1.10 and have a few questions.

I had a TileEntity with a custom renderer.

But a lot methods changed in the block.

How do I set the following in 1.10:

setBlockBounds((float) START_COLLISION, (float) BOTTOM_COLLISION, (float) START_COLLISION, (float) END_COLLISION, (float) HEIGHT_COLLISION, (float) END_COLLISION); 

    @Override
    public boolean isFullCube(IBlockState state)
    {
        return false;
    }

Currently the block doesn't move but it is planned for the future that's why we use the TileEntitySpecialRenderer.

The entity is missing the texture and the bottom seems to be opaque.

Where is that block animated?

Raycoms · September 9, 2016

Currently the block doesn't move but it is planned for the future that's why we use the TileEntitySpecialRenderer.

It's not animated yet but we're planning to.

diesieben07 · September 9, 2016

setBlockBounds((float) START_COLLISION, (float) BOTTOM_COLLISION, (float) START_COLLISION, (float) END_COLLISION, (float) HEIGHT_COLLISION, (float) END_COLLISION);

Use the bounding box methods in Block.

@Override
    public boolean isFullCube(IBlockState state)
    {
        return false;
    }

Still exists.

Raycoms · September 9, 2016

But both these methods are deprecated, so there should be something better to use?

It still doesn't render the texture though.

http://www.minecraftforge.net/forum/index.php/topic,41630.msg221131.html#msg221131

It still doesn't render the texture though.

What is

Constants.MOD_ID

? Show a screenshot of the texture file in the file explorer of your IDE, showing the file tree.

Raycoms · September 9, 2016

/src/main/resources/assets/minecolonies/textures/blocks/blockScarecrowPumpkin.png

But I'm sure that is correct (If I remove a bit of this resource location he will throw an exception that he is unable to find)

Constants.modId is "minecolonies"

diesieben07 · September 9, 2016

Then what exactly is the issue? You said "it's not rendering the texture", which to me implies "it's using the missing texture".

Raycoms · September 9, 2016

It just renders it black and not with the texture, although he is loading the texture correctly, therefore, something is going wrong while setting it.

And renders the onclosing blocks transparent.

diesieben07 · September 9, 2016

Who is "he"? Did you set the block bounds correctly now?

You might also need isOpaqueCube set to false, depending on your model.

Raycoms · September 9, 2016

Okay, great thank you, that opaque cube method fixed it.
