Vehicle parts

0.D (Danny)

Vehicles consist of parts, which can be damaged and eventually broken. Parts can be external, or internal (which are mounted inside the former). External parts are enclosed in [square brackets], internal parts in -dashes-.

Internal parts which are tagged as 'over' are a special case. They will be enclosed in (round brackets), override the color of the external part, and will function as armor — protecting other parts in this tile from damage (although not infallibly).

Vehicle tiles can be tagged as inside (marked as In) or outside (Out). Inside tiles protect from weather effects, while outside ones don't. To become an inside tile the tile must have a roof, and the adjacent tiles must have either roof or some impenetrable obstacle (like a closed door or windshield).

The mass, top and safe speed, acceleration, fuel consumption, noise and mobility of a vehicle is based on its composition. For example, safe speed is the speed at which engine can pull the mass without damaging the engine.

List of parts

A list of all the parts you can install in a vehicle, detailing their characteristics, the required components in order to install them and miscellaneous notes.

The Par column has different meanings depending on the type of part:

  • power for engines (top speed) and solar panel (% of 1 fuel per turn, can be > 100)
  • size for wheels (inches)
  • capacity for fuel tanks and parts that allow storing cargo
  • bonus for seatbelt (str) and muffler (%)
  • energy consumption for parts that require power from the car battery to work

Steel frame, steel plating, as well as spiked plating and hard plating can be crafted with a welder by using lumps and chunks of steel.

Wheels

Every vehicle needs wheels to be able to move. A vehicle without wheels can only be dragged.

In general, a vehicle needs at least two wheels. Wheels need to be positioned in such a way that the center of weight is roughly above them. There is no requirement that the wheels have similar shapes or sizes.

Wheel size, width, and style influence the wheel's rolling resistance and off-road performance. In general, more wheels, wider wheels, and wheels intended for off-roading have higher rolling resistance, which reduces overall vehicle speed. But those factors also improve off-road performance.

A vehicle with 0 total wheel area won't be able to move by itself.

Boats

A vehicle can have both wheels and boat hulls, but not both in same tile. More boat hulls increase the height of the vehicle's water tight frame and reduce draft, and a vehicle will sink if its draft is more than the height of the water tight frame.

Engines: load vs strain

Load is (engine power used)/(maximum engine power output). In case of a single undamaged engine, this translates to (engine power)/(max power). Damaged engine's power output is proportional to it's remaining hp percentage. Multiple engines' output is multiplied by 4/(num_engines + 3). Note that adding a weak engine to a powerful engine can actually decrease the overall power output (and thus increase engine load for a given speed).

Load affects fuel usage, smoke and noise. Load is processed twice: once for driving, once for having an active engine. When driving, load is equal to percentage of acceleration used (ie. if acceleration is 50 and vehicle accelerates from 0 to 24, load is 0.48). The second load is equal to sum of alternator loads or 0.01, whichever is higher.

Strain is (|current velocity| - safe velocity)/(max velocity - safe velocity). Strain greatly increases fuel consumption (100 times more on max velocity than on safe velocity) and causes engine damage, unless the engine is powered by muscles. Muscle powered engines will instead drain extra resources from the driver (5 times as much at max velocity as on safe velocity).

Turrets

Turrets fire automatically at enemies as long as they have ammo and are turned on. They can shoot at your own car, but they can only damage it with area attacks (bullets that hit the turret's car will not damage it). They will avoid shooting the player, but it can be unreliable, especially when standing close to the turret.

Stats

Turrets use stats from the weapons used to create them, modified by their ammo. The exception is the range - most turrets have automatic targeting range far below weapon range. Turrets track AoE (area of effect) of their projectiles and will not target enemies too close to hit without damaging self. Effective area of effect used for safety calculations is bigger than actual one: by 1 if it was 1 before, by 2 if it was 2 or more before.

Turret shoots like an NPC with 8 in specific weapon skill (for example, rifles), 4 in marksmanship, 16 strength, 8 dexterity and 12 perception. An active turret will take one shot or burst every turn it can. It has no speed stat, nor does it accumulate moves.

Turrets have different recoil mechanics from regular guns. Their recoil always starts at 25% of their vehicle's velocity in MPH and is reset at the start of the turn. Recoil from previous shots in burst is respected.

IFF (player's safety)

When the player is visible to the turret and close enough to it, it will not target any enemy within (30 + 2 * AoE) degree cone centered at the player. This includes enemies much closer to the turret than the player. As the player gets closer to the turret, the cone is widened to 60 degrees (at 2 tile distance) and then 120 degrees (when adjacent). "Close enough" depends on turrets range: (range + AoE) * 1.5 + 6.

Shooting limitations

Turrets can shoot all creatures not covered by roofs of their own vehicle (except player, who only needs to be on any part of the vehicle). Roof over player's head does NOT stop the IFF.

Turrets can't damage own vehicle with bullets alone, though it can do so with AoE projectiles.

Automatic targeting

An active turret will try to target any visible hostile creatures. Friendlies are ignored (neither targeted nor avoided). Closer enemies are preferred (unless too close to target with AoE). Turrets can't see in the darkness and will not consider invisible player's safety. Automatic targeting has a severe range limitation - 12 tiles in case of most turrets, 5 in case of flamethrowers.

Turret's aiming system is purely visual and has no night vision ability.

Manual targeting

Manual targeting forces a target for the turret. It won't make it shoot faster or more accurately than otherwise, but it can make it shoot much further (up to gun+ammo range). Turret's configuration (burst/once) is respected. If the turret was disabled before aiming, it will be enabled for one burst, then disabled.

Aiming takes some time and does not consider player's safety (IFF). If the vehicle moves between aiming and shooting, the target point will be shifted by in the same direction and the same distance as the vehicle (rotation is ignored).

Manual targeting can make the turret shoot over opaque parts of turret's vehicle.

Settings

Turrets start out disabled. To make them shoot, you need to configure them and turn on the vehicle's turret system. Each turret can be configured to shoot in bursts, only once per turn or not at all.
