Bolt-action hopper-fed Ballista

This ballista, with a hopper magazine and bolt-action sliding breech system, relies on springs for 100% of its launching power. It fires 3kg projectiles at around 200km/h, potent enough to damage creations with invincibility off. Cocking Instructions: After unfreezing, turn on the motor with mouse4, press Y to engage the gear clutch, and cock back the springs, moving the bolt (white blocks behind the barrel) towards the catch (black blocks near the back). When blocks collide, hold U to bring the catch up, allowing the bolt to move far enough back to have the catch fall in front of it. Once the catch is engaged, disengage the gear clutch with Y, moving on to chambering. Chambering Instructions: After cocking (be sure to disengage the gear clutch with Y), press [ and ] (the buttons under minus and equals) to move the hopper piston up and down, which will eventually shimmy a round onto the yellow-painted part under the hopper. Now use the grab tool to grab the red sphere near the front of the Ballista, unlock it and rack the bolt fully back and forward, locking it once again once complete. Then, pull the green sphere near the front to open the breach, dropping the round into the chamber. Once a round has been successfully chambered, pressing T and G will aim the whole Ballista up and down, with an angle readout near the bolt for predictable angled shots. It goes from -25 to +58 degrees. Once aimed, you can press U to fire the round, repeating the process to fire again.
