Inspired by Piston Control from the_will_bl

This mod gives you control over the way pistons move blocks with four new data pack tags:

pistoncommand:piston_behavior_normal - pistons can push and pull the block like normal
pistoncommand:piston_behavior_block - blocks pistons like obsidian or bedrock
pistoncommand:piston_behavior_destroy - gets destroyed like beds and torches
pistoncommand:piston_behavior_push_only - can be pushed but not pulled with a sticky piston, like glazed terracotta

Also lets you move block entities like chests and furnaces. You can turn this on for all blocks in the mod config (Mods > Piston Command > Config) or by setting push_block_entities to true in your server's config/pistoncommand-server.toml.

You can match Bedrock behavior by installing the Bedrock Pistons data pack and turning on Push Block Entities. This makes all block entities pushable other than campfires, signs, banners and broken modded blocks.

Works with vanilla and Fabric clients when installed on the server. We're trying to be compatible with as many other mods as possible. If you notice any problems like blocks not updating or visual bugs please report them on GitHub.

Incompatible Blocks

Some modded blocks can stop working when pushed. You should never add these to piston_behavior_normal or piston_behavior_push_only:

Create mechanical belt - separates from other belt blocks, stops moving items even if pulled back and plays a broken animation
Create fluid tank - breaks the multiblock structure
Create mechanical piston - leaves behind useless and visually broken extension poles
Anything tagged as #c:relocation_not_supported. Other mods use this tag for blocks that can trigger gamebreaking bugs or even crash the server when moved with a piston.
