Auto Turrets

Auto Turrets are weapons that are wielded by Defenders, Auto 5s, Auto 3s, Auto Gunners, Auto Smashers and Auto Trappers in Diep.io. Auto Tanks also used to use them. Auto Turrets are gray circles with barrels on them, attached to or on top of a tank that fire at nearby targets automatically without needing player input. When attached to the side of a tank (as seen on the Auto 3 and the Auto 5) only half of the circle beneath the barrel can be seen.

Artificial Intelligence
When AI-controlled:


 * The Auto Turrets will attack the closest target and keep attacking it until it dies or goes out of range.

It's possible to take control of them:
 * The Auto Turrets prioritize tanks over shapes.
 * The Auto Turrets don't attack projectiles.
 * The Auto Turrets seem to prioritize the most aggressive thing near you. Example: You are in the pentagon nest, and there is a Alpha Pentagon nearby, with a Crasher coming after you. The auto turret will almost always attack the Crasher.


 * Players can control the Auto Turret(s) closest to their mouse (if more than one exists), by left-clicking, pressing space or having Auto Fire turned on (does not apply to tanks which have an alternative fire power).


 * Right-clicking or pressing Shift will instead fire from the Auto Turret most far away from the cursor (does not apply to tanks which have an alternative fire power).
 * Multiple Turrets can be controlled if both are close enough to the mouse (only applies to Auto 3 and Auto 5).

Properties

 * Auto Turrets fire Bullets which are slightly smaller than that of other tanks.
 * They have unnaturally high Bullet Penetration for their size, but move slightly slower.
 * Auto Turrets on the Auto Tanks can only turn their barrels a certain total angle.
 * This is why you take control of different Turrets as you move your cursor around the tank.
 * Should an object leave their angle range, the next turret will take over.

Wielders

 * Auto 3: Has three evenly spaced controllable Auto Turrets attached to the tank.
 * Auto 5: Has five evenly spaced controllable Auto Turrets attached to the tank.
 * Auto Gunner: Is a Gunner with an uncontrollable Auto Turret on top of it.

History

 * Auto Turrets were first added through the Auto Gunner on August 1, 2016.
 * On August 2nd, 2016, the Auto Tank was added, and in the same day removed.
 * On the same day, the Auto 3 and Auto 5 were added to replace the Auto Tank.
 * On August 15th, 2016, the Auto Trapper was added.
 * On September 13th, 2016, the Auto Smasher was secretly added.
 * This is because the developer was pushing some hotfixes and forgot he added it.

Trivia

 * Drones (when not manually controlled) exhibit very similar behavior to Auto Turrets in the fact that they spin/follow their owner slowly when nothing is in range and attacking nearby tanks and Polygons when near.
 * The Battleship's Protectors will NOT circle the player due to them being able to detect tanks and polygons from far distances.
