- For specific types of tanks in Diep.io, see Tiers.
Classes are commonly composed out of three, very distinct parts: The tank itself or ‘the body’. It’s Weapon/s (Cannons, Spawnners, Launchers, etc). And the Projectiles or ‘the ammunition’ that is spawned from it.
The body of a tank, it has the same base durability regardless of class or shape. It is only modifiable through the Tank’s Body Damage, Max Health and Regeneration stats. The only exception to this being the Smasher branch, which sports additional base Body Damage. Almost all playable tanks have a circular body. The only exceptions to this being the Necromancer, and the Factory, which are square shaped. The game revolves around destroying this part of the tank. If it despawns, the tank dies.
Weapons appear in different shapes, sizes and numbers. they are not tangible parts of the tank, and their primary function is to let the player aim and control where its Ammunition spawns. The most common types of weapons are Cannons, followed by Spawners, Launchers and Deployers. The Ammunition that each of this types spawns being Bullets, Drones, Traps and Missiles respectively.
Bullets, Drones, Traps and Missiles are tangible entities spawned from the Weapons location, who’s main job is to destroy the enemies bodies by colliding with them. Depending on the Class and Weapon type, the ammunition may present different traits such as Speed, Durability, Size and Lifespan. Additionally, special ammunition types such as drones are the only entities who’s Trajectory is not fixed, and can thus be updated to make it more difficult to block/dodge.
- The color of a tank’s body is based on its team’s color (blue, red, purple or green).
- Your tank is colored blue in FFA and Maze, while everyone else’s is red.
- Neutral tanks, like Arena Closers or unclaimed Dominators are always yellow.
- Some Bosses have special colors, such as pink or yellow.
- Fallen Bosses are light grey.
- The outlines of tanks and Cannons are slightly darker than the body.
- Cannons are always colored dark grey.
- Bullets are usually the same color as the tank who fired them.
- In FFA and Maze, a Necromancer’s Drones are colored peach/orange.
- Main article: Controls
All controllable tanks can move their body with the arrow or WASD keys. They can move their Cannon(s), which always points at the cursor, with the mouse. Pressing C will make the tank spin automatically.
Shooting Traps or Bullets Edit
To shoot ammunition, a player can press SPACE, or left click with their mouse. Pressing E will enable the tank to fire automatically. However, Smasher and its upgrades (except Auto Smasher) lack the ability to shoot Bullets.
Controlling Drones Edit
For any tank that utilizes controllable Drones, left-clicking (or SPACEBAR) will bring the Drones towards the mouse cursor. This is always on if Auto Fire is enabled. Right-clicking (or SHIFT) will repel them away from the cursor. Otherwise, the Drones will return to the tank and orbit it, unless there is a Polygon, a Boss or another enemy tank nearby. In the case of you using Factory, your Minions shoot to your cursor when left clicking or Auto Fire is on, and looks away, or if close, gets dragged (only if cursor is close to the Minions|Minion) if right clicking.
Other Controls Edit
Some tanks have additional controls as well. For example, right-clicking while playing as the Predator will extend its focus in the direction of the mouse.
Spawning is the act of being born into the arena. It is done by pressing enter on the computer version, or by pressing the green arrow button below the player's name, in the mobile version. A player will always spawn as a basic Tank. The player will spawn in their base in 2 Teams, 4 Teams, or Domination. In FFA, Survival, Tag, Maze, or Sandbox, the player will spawn at a random point on the map.
When the player spawns, they rotate for a second. Their body also flashes slightly for approximately 15 seconds. During this time the player cannot be harmed. In this time, if they collide with Crashers, Polygons, Bullets, Tanks, or any other entities, the entity will be destroyed, at no health cost to the player. Undisturbed, this period of invincibility lasts for approx. 15 seconds, however if the player moves or fires, then the period is stopped. However, a player can select upgrades, or fill in the stat bar during this time. This feature was created to prevent tanks being spawn killed.
The level a tank spawns at is determined by the level it was killed at previously. If this is the first time the server has been joined, then the tank will spawn at level 1. A level 45 tank will spawn at level 22, with a range of values in between. If a player leaves the site, then returns, they will spawn at level 1. The level a player will spawn at is shown below their name.
