Problem: Calling robot.swing() will always return false, no matter energy level, equipped tool, selected item or block in front of the robot.

Steps to reproduce:

1. Create a fresh installation of minecraft 1.16.5 with forge 36.2.24 and run it with java 8
2. Place a robot, place a block in front of it and give it an appropriate tool, run lua and then robot.swing().
3. The robot returns false no matter what.

No matter if called through the lua interpreter or through a standalone program, robot.swing() never works.
