I want to build a "rocket" out of concrete powder. I have a command block that gives a levitation effect to entities within 5 blocks of the command block. This is how I have the rocket set up:
Top layer: 2x2 square of concrete powder.
Layer 0: 2x2 piston door that is sideways.
On the press of a button, the piston door opens, causing the concrete powder to become an entity and fall. The command block activates, giving all entities within 5 blocks of it Levitation 255 for 1 second. However, I only get levitated, and the blocks just fall and plop onto the ground. The concrete powder is in range of the command block, but it won't fly up into the air. Is it possible to add status effects to falling block entities (i.e. sand, gravel, concrete powder, and/or primed TNT)?
