How to change a piston direction?

I need some help to change a piston direction while placing it programmatically.

I use this method to set my block type to a piston:

block.setType(Material.PISTON_BASE);

But I can't find a method to change its direction, and point it down.

Solution

  • Bukkit has utility methods to change facing of the piston using the MaterialData api, this api can be used as follows:

    Block block = ....;
BlockState state = block.getState();
PistonBaseMaterial piston = (PistonBaseMaterial)state.getData();

piston.setFacingDirection(BlockFace.NORTH);
piston.setFacingDirection(BlockFace.SOUTH);
piston.setFacingDirection(BlockFace.WEST);
piston.setFacingDirection(BlockFace.EAST);
piston.setFacingDirection(BlockFace.UP);
piston.setFacingDirection(BlockFace.DOWN);

state.setData(piston);
state.update();

    Outside of the direction, we can also power/unpower the piston by calling piston.setPowered(true/false);. We can also easily check if the piston is a sticky one by calling the method piston.isSticky(), without relying on the other deprecated methods since we are no longer using "magic id's" anymore.
