If you have any idea how can i set block for a falling block using metadata, please let me know

[GliczDev]

When I change rewriting block display from falling block to armor stand, it shows, any idea why???

[tomcraft]

The falling block entity doesn't use the metadata system to define its blockstate.
One idea would be to cancel the spawn packet and send a falling block spawn when you receive the blockstate metadata.

[GliczDev]

Okay, but how can I send a falling block spawn

[tomcraft]

You have to build the packet from scratch using PacketWrapper. I think you can find some examples in other places of the source-code.

[GliczDev]

Unfortunately i still don't know how to do this. If I won't find solution, I'll just leave it without block display fix

[GliczDev]

Finally, I almost fixed block display, but I don't know how can I set and read metadata in spawn entity packet handler

[GliczDev]

Also, display entities have 0.5 'added' to x and z position, and when I add it to this falling block, after some time it removes this position change

wrapper.set(Type.DOUBLE, 0, wrapper.get(Type.DOUBLE, 0) + 0.5);
wrapper.set(Type.DOUBLE, 2, wrapper.get(Type.DOUBLE, 2) + 0.5);

[GliczDev]

As I see, entity meta is sent after spawn entity, so idk how can I finish fixing block display entity

[FlorianMichael]

Are you still working on this PR / planning on updating it?

[GliczDev]

I totally forgot about this PR because of problems I had, I can try to finish it
