      Parameters

      Returns (arg: PistonActivateAfterEvent) => void

      Adds a callback that will be called when a piston expands or retracts.

      This function can't be called in read-only mode.

      // set up a couple of piston blocks
      let piston = overworld.getBlock(targetLocation);
      let button = overworld.getBlock({
      x: targetLocation.x,
      y: targetLocation.y + 1,
      z: targetLocation.z,
      });

      if (piston === undefined || button === undefined) {
      log("Could not find block at location.");
      return -1;
      }

      piston.setPermutation(
      mc.BlockPermutation.resolve("piston").withState("facing_direction", 3)
      );
      button.setPermutation(
      mc.BlockPermutation.resolve("acacia_button").withState("facing_direction", 1)
      );

      mc.world.afterEvents.pistonActivate.subscribe(
      (pistonEvent: mc.PistonActivateAfterEvent) => {
      let eventLoc = pistonEvent.piston.block.location;

      if (
      eventLoc.x === targetLocation.x &&
      eventLoc.y === targetLocation.y &&
      eventLoc.z === targetLocation.z
      ) {
      log(
      "Piston event at " +
      mc.system.currentTick +
      (pistonEvent.piston.isMoving ? " Moving" : "") +
      " State: " +
      pistonEvent.piston.state
      );
      }
      }
      );
