#summary List of all gear types

This is a list and overview of all gear types.

This page is split in two parts: The first part is a short list, the second part gives a longer description for all gear types and also describes the meaning of the gear values (such as timer, pos, health, etc.).

Please note this page is still a work in progess. The categories presented here are purely for a better overview here; they do not neccessarily reflect anything in the actual game’s source code.

A “TODO” means that this particular section is not yet finished and may be not accurate.

== Long descriptions and values ==

This section gives longer description of the various gear types and how their values (i.e. tag, pos, timer, health, etc.) are interpreted. The gear values are pretty chaotic, so they are described for each gear seperately. Use the various setter and getter functions for gears to modifiy the gear values.

In Lua, use the functions `GetGearPos`, `SetGearPos`, `GetTag`, `SetTag`, `GetTimer`, `SetTimer`, `GetHealth`, `SetHealth`, `GetFlightTime`, `SetFlightTime`, `GetGearValues` and `SetGearValues` to query or modify the gear values.

=== Land objects ===

This is a list of gears which usually stay on the land for a long time and stay for several rounds and can’t normally directly placed by players.

==== `gtCase` ====

An ammo, utility or health crate.

 * `Pos`: Crate type: 1=ammo crate, 2=health crate, 4=utility crate

 * `Tag`: Used for the appear animation

 * `Health`: Amount of health contained in a health crate

==== `gtExplosives` ====

An explosive barrel. It has its own invisible health, like a hedgehog. On low health levels smoke comes out of the barrel.

 * `Health`: “health” of the barrel: Starts at 60, explodes at 0.

==== `gtFlake` ====

A snowflake which might become part of the terrain.

==== `gtFlame` ====

A single flame.

TODO: Flame size.

 * `Pos`: Some unknown value between 0-32 (TODO)

 * `FlightTime`: If set to `0`, this flame can hurt hedgehogs even in mid-air. By default, the FlightTime is a non-zero value.

==== `gtGrave` ====

A grave from a dead hedgehog.

 * `Health`: Used when being resurrected.

==== `gtHedgehog` ====

A hedgehog.

 * `Tag`: Used for animation. `0` = no animation plays. Other value: animation plays

 * `Health`: Hedgehog's health.

TODO: Write more about hedgehogs.

==== `gtPortal` ====

A portal from the portable portal device.

 * `Tag`: Portal state. 0=orange flying, 1=orange placed, 2=blue flying, 3=blue placed

 * `Timer`: Remaining existance time (portals will disappear after end of turn).

==== `gtTarget` ====

A target, useful in target practice missions.

=== Utilities ===

The gears used by various utilities.

==== `gtGirder` ====

A girder (construction).

TODO

==== `gtJetpack` ====

A flying saucer. Its fuel is stored in `Health` and starts at 2000, which stands for 100% fuel. The fuel value is reduced whenever the player taps one of the direction keys. The up direction costs 50 fuel and the left and right directions cost 10 fuel.

 * `Health`: Amount of remaining fuel. `2000` denotes 100% fuel.

==== `gtLandGun` ====

The land spray tool.

 * `Tag`: Spitting power of land spray (`5`-`20`).

 * `Health`: Amount of fuel. `1000` denotes 100% fuel. ||

==== `gtParachute` ====

A parachute.

==== `gtResurrector` ==== 

A hedgehog which does perform a resurrection.

 * `Radius`: Effect range of resurrection in pixels (default: 100). Note that this does not change the drawn circle

==== `gtRope` ====

A rope.

 * `Tag` Rope style: `0`=classic white segments (default), `1`=simple line which can be colored with `Tint`.

 * `Tint`: Rope color as RGBA. This only works if `Tag` equals `1`

==== `gtSwitcher` ====

Switch hedgehog.

==== `gtTardis` ====

A !TimeBox. It works in several phases and an internal timer.

 * `Pos`: Current phase. The value `4` is used when the !TimeBox is currently time-travelling (has completely turned invisible).

 * `Timer`: Has several meanings, depending on `Pos`. Here's the most imporant one, for `Pos` of `4`: A timer (in milliseconds) containing the remaining time until the !TimeBox returns. The !TimeBox returns when `Timer` reaches 0. Hedgewars decreases the timer only while the same team is playing

 * `Tint`: RGBA color (default: clan color)

TODO: Add more information for the other phases.

==== `gtTeleport` ====

Teleportation.

=== Weapons and main projectiles ===

Gears of weapons which can be directly used or launched by the players.

==== `gtAirAttack` ====

The airplane of an airborne attack.

 * `Pos`: Type of airborne attack: `0` = Air Attack, `1` = Mine Strike, `2` = Napalm, `3` = Drill Strike

 * `Tag`: Direction of airplane: `-1` = left, `1` = right

 * `Health`: Number of bombs/mines/drills left (default: 6)

 * `Damage`: Distance (in pixels) between two dropped bombs/mines/drills (default: 30)

 * `Tint`: RGBA color of airplane (default: clan color)

==== `gtAirMine` ====

An air mine. It seeks nearby hedgehogs. If it is in explosion range, its timer activates and will become lower. If the timer reaches 0 and is still in explosion range of a hedgehog, it explodes. But it does not explode if it is out of range, after which the timer is reset and the air mine can be activated again.

To properly set the timer of an air mine, you must set both `Timer` and `WDTimer`.

If the gear state flag `gstAttacking` is set, the air mine is activated and is about to explode.

If the gear state flag `gstChooseTarget` is set, the air mine is currently hunting a hedgehog. This should only be read by Lua scripts, setting it from a Lua script has no effect.

 * `Pos`: Air friction. Higher values mean slower movement. 

 * `Timer`: Time left until possible detonation (in milliseconds). Default value depends on game scheme.

 * `WDTimer`: Initial timer value (in milliseconds) of an activated air mine. The `Timer` is reset to this value if the air mine gets re-activated.

 * `Angle`: Range in which it seeks and follows hedgehogs, in pixels. If a hedgehog is within this range, the air mine will start following. Set it to `0xFFFFFFFF` for an infinite seek range. Set to `0` to disable following. Default: 175

 * `Power`: Speed in which it seeks and follows hedgehogs.

 * `Karma`: Explosion size and damage. Default: 30

==== `gtBallGun` ====

A ballgun. This weapon is timer-based.

 * `Timer`: Remaining usage time (in ms), default is 5001. One ball is fired every 100ms.

==== `gtBee` ====

A homing bee. The bee works in up to three phases: The first phase is the pre-homing phase lasts 0.5 seconds in which the bee behaves like a normal projectile. In the second phase the bee actually starts homing. This phase can last up to 5 seconds. If the bee did not explode in this time, the bee goes into post-homing phase, stops homing and simply falls. For the first two phases this gear uses `Timer`.

This gear does not directly store in which phase the bee currently is in, so it is a bit tricky to modify the timer values.

If you just want to modify the pre-homing time, simply set the `Timer` after creation. But if you want to modify the duration of the homing phase, you have somehow track the bee gear and wait until the `Timer` first reaches 0, so you know the bee will now get into its second phase. Now wait one more tick (or more) and set `Timer` to set the maximum flight time in the homing phase.

 * `Tag`: Whether the bee is underwater (`0` = no, `1` = yes). This is used for the sound effect.

 * `Timer`: Remaining time (in milliseconds) either of the pre-homing phase or the homing phase.

==== `gtBirdy` ====

Birdy. Birdy works like a flying saucer and depletes energy (stored in `Health`) whenever you tap one of the direction keys. Flapping left and right costs 10 energy, flapping upwards costs 50 energy.

 * `Tag`: Facing direction (`-1` = left, `1` = right)

 * `Health`: “Flapping energy” left, default is 2000

 * `FlightTime`: Number of eggs left (default: 2)

==== `gtBlowTorch` ====

A blowtorch. This utility is entirely timer-based.

 * `Timer`: Remaining usage time in ms, default is 7500.

==== `gtClusterBomb` ====

A cluster bomb.

==== `gtCake` ====

A cake. 

 * `Tag`: A timer used for several animations. The final animation (sit down) will cause the cake to explode when the tag reaches `2250`.

 * `Health`: Remaining walking time, default is 2048. Note: the cake uses its own time unit.

==== `gtDEagleShot` ====

A shot from a Desert Eagle.

 * `Health`: How deep the bullet digs into land. Default: 50.

==== `gtDrill` ====

A drill rocket. This is either a launched drill rocket or a small drill rocket from the drill strike (which is a bit weaker than the launched one).

The type of drill rocket is stored in the gear state. If `gsttmpFlag` is set (e.g. {{{band(GetState(yourDrillGear), gsttempFlag) == 0}}} evaluates to `true`), it is a launched drill rocket, otherwise it is a drill rocket from the drill strike.

 * `Tag`: Used for drill strike. If `1`, then first impact occoured already.

 * `Timer`: Detonation timer (in ms)

==== `gtDynamite` ====

A dynamite.

Note: The current animation does not support denotation times above 5 seconds. If you want to have larger times, you have to provide your own dynamite sprite in a sidecar HWP or find another workaround.

 * `Tag`: Displayed animation frame.

 * `Timer`: Detonation timer (in ms). Default: 5000.

==== `gtFirePunch` ====

A hedgehog which performs the Shoryuken attack.

 * `Tag`: Current Y coordinate of the hedgehog.

==== `gtFlamethrower` ====

 * `Health`: Remaining travel range. Default: 2048

==== `gtKnife` ====

A cleaver.

==== `gtPiano` ====

A piano from piano strike.

 * `Tag`: Number of remaining terrain bounces. Default: 5. If this number reaches 0, the piano will not collide anymore and directly fall into the water.

A pickhammer. This gear is entirely timer-based.

 * `Timer`: Remaining usage time (in milliseconds). Default: 4000

==== `gtRCPlane` ====

An RC plane.
