Recap: Modular Turret

Build the test range's two turrets from parts. TurretControl.cs already turns each turret with the left and right arrows, and Shell.cs flies a shell forward. The scene gives Turret1 a Cannon and an Ammo with 4 shells, and Turret2 a TwinCannon and an Ammo with 3 shells. Write the parts:

• Ammo: a public int shells and a public method bool Take(). With a shell left, it uses one and returns true. With none, it logs the object's name and is empty, as Turret2 is empty, and returns false.
• Weapon: an abstract component that always comes with an Ammo, with a public shellPrefab (a GameObject), a public float cooldown (the Inspector sets 1) and a public method Pull(). A pull during the cooldown does nothing and uses no shell. Otherwise, if Take() gives a shell, the cooldown starts and Fire() runs, an abstract method each weapon writes.
• Cannon fires one shell from 1 unit in front of the turret. TwinCannon fires two for one shell of ammo, from 0.4 to the left and 0.4 to the right of that spot. A shell starts at transform.position + transform.rotation * offset, turned like the turret (transform.rotation), where offset is the spot seen from the turret, such as new Vector3(0f, 0f, 1f).
• In TurretControl, Space pulls the trigger of whatever Weapon the turret has.

Press Play, turn and fire until both turrets are empty, then Check.
