Version 0.9.13 of Hedgewars introduced the ability to use Lua scripts to modify Hedgewars behaviour for different maps without having to recompile the whole game. The till then used triggers (only appeared in training maps) were removed.

Lua is an easy to learn scripting language that’s implemented using open source libraries. If you’d like to learn more about Lua, have a look at [http://www.lua.org Lua's official homepage]. Even though its easy to learn syntax this wiki page won't explain all basics of using Lua, e.g. declaring variables or using control structures. There are tons of step-by-step tutorials and documentation available on the internet. Just throw “Lua” into your favourite search engine and give it a try.

As of Version 0.9.20, Hedgewars supports Lua scripts for two similar tasks: Define tutorial missions, campaign missions or provide special map behaviour for precreated maps. It is also used for multiplayer scripts to create new game styles.

Tutorial missions are located within text files inside `share/hedgewars/Data/Missions/Training`. The game will list all files with the lua extension inside this directory in the Training selection screen. You’ll find some premade example scripts within this directory that contain several comments on the script lines and what they do.

In addition to tutorial missions predrawn maps (maps not created using the random map creator) may contain a single lua script file named `map.lua`. If it’s there, it will be used once the map is played. This way it’s possible to play maps alone or over the internet using custom goals. Mission maps can be found in singleplayer mode under the “training” button and in multiplayer mode, it is selectable as a map type.

Several parts of script files are executed multiple times. In general, the whole script file is read while loading the map. Declarations as well as function calls outside functions are executed at once. Later on the game will call special predefined function names at special occassions such as the creation of new game objects (called “gears”).

It is possible to play missions in multiplayer. However this requires all participating players to have the exact same version of the map files, including the `map.lua` script file. If this isn’t the case the game will probably desync and “kick” at least the one player using a different version of the map files. To avoid problems when running prepackaged maps, you should never modify any maps provided with the Hedgewars default package. Instead, create a copy of the existing map and modify this one. Feel free to share your work on the forums.

Another thing to note is the current status of our scripting implementation. Similar to the whole game, this is still work in progress and we can’t guarantee that scripts working in this version will run in future revisions of the game as we might extend, change or rename parts of the scripting engine.

Global variables are used by the game to interact with the scripts by passing and retrieving their values. While some of the variables are never read by the engine some allow you to modify the engine’s behaviour, e.g. the theme to be used for the current map.

Four-byte (RGBA) colors use the first 3 bytes for the color components (like for the 3-byte colors) and the fourth byte is used for opacity, where 255 means maximum opacity and 0 means fully transparent (also called the “alpha channel”).

Most variables are optional, but for missions, `Theme` must be set by the scripter if you want to use a random map, rather than an image map. All other variables do not need to be set by the scripter and have default values.

This creates a new gear at position x,y (measured from top left) of kind `gearType` (see [GearTypes Gear Types]). The initial velocities are `dx` and `dy`. All arguments are numbers. The function returns the `uid` of the gear created. Gears can have multple states at once: `state` is a bitmask, the flag variables can be found in [States].

This creates a new visual gear at position x,y (measured from top left) of kind `visualGearType` (see [VisualGearTypes Visual Gear Types]). The function returns the `uid` of the visual gear created.  Set `critical` to `true` if the visual gear is crucial to game play. Use `false` if it is just an effect, and can be skipped when in fast-forward mode (such as when joining a room). A critical visual gear will always be created, a non-critical one may fail. Most visual gears delete themselves.

If `ammoType` is set to `amNothing`, a random weapon (out of the available weapons from the weapon scheme) will be selected. If `x` and `y` are set to 0, the crate will spawn on a random position (but always on land). The `amount` parameter specifies the amount of ammo contained in the crate. By default, the value set by `SetAmmo` is used. If `SetAmmo` has not been used for this ammo type, an ammo-type-dependent default value is used.

The `Tag` of a gear is just another arbitrary variable to hold the gear's state. The meaning of a tag depends on the gear type. For example, for `gtBall` gears, it specifies the ball color, for `gtAirAttack` gears (airplane) it specifies the direction of the plane, etc. See [GearTypes] for a full list. The returned value will be an integer.

In 0.9.16 ammo can be set directly via the optional third parameter, `ammoCount`. A value of 0 will remove the weapon, a value of 100 will give infinite ammo.

Sets the `Tag` value of the specified gear (by `gearUid`). The `Tag` value of a gear is simply an extra variable to modify misc. things. The meaning of a tag depends on the gear type. For example, for `gtBall` gears, it specifies the ball color, for `gtAirAttack` gears (airplane) it specifies the direction of the plane, etc. See [GearTypes] for a full list. `tag` has to be an integer.

Places a [Sprites sprite] at the specified position (`x`, `y`) on the map, it behaves like terrain then. Unlike `PlaceGirder`, this function does not check for collisions, so the sprite can be placed anywhere within map boundaries. The function returns `true` if the placement was successful, `false` otherwise. `frameIdx` is the frame index starting by 0. `frameIdx` is used if the sprite consists of several sub-images. Only a subset of the sprites is currently supported by this function:

`tint` is for an RGBA colouring to apply, this works about the same as `Tint` in gears. `behind` indicates the sprite should not replace existing land. `flipHoriz` and `flipVert` are for mirroring the sprite vertically and horizontally before placing, respectively.

Erases a [Sprites sprite] at the specified position (`x`, `y`) on the map. `frameIdx` is the frame index starting by 0. `sprite`, `frameIdx`, `flipHoriz` and `flipVert` behave the same as in `PlaceSprite`. For `sprite`, the same subset of sprites is permitted.

Set `eraseOnLFMatch` to `true` to erase all land for a pixel that matches any of the passed in land flags.  This is useful if, for example, an `lfBouncy` sprite was placed “behind” land using `PlaceSprite` and you want to remove it without destroying the non-bouncy terrain.

Set `onlyEraseLF` to `true` to only remove specific land flags. If for example a sprite consists of `lfIndestructible` and `lfBouncy`, and you call `EraseSprite` with `onlyEraseLF` and `lfIndestructible` set, the sprite will remain bouncy but can be destroyed.  You can use this to entirely remove all land flags from a sprite—at this point the sprite will be visual only, painted on the map but with no collision.

Returns a randomly generated number in the range of 0 to number - 1. This random number uses the game seed, so is synchronised, and thus safe for multiplayer and saved games. Use `GetRandom` for anything that could impact the engine state. For example, a visual gear could simply use Lua’s `math.random`, but adding a regular gear should use `GetRandom`.

Display an event text in the upper part of the screen with the specified RGBA [LuaAPI#Color color] and caption group. Although an RBGA color is used, Hedgewars does not actually support transparent or semi-transparent captions, so the fourth byte is ignored. We recommend you to always specify a full opacity (`FF` in hexadecimal) for the caption.

`TStatInfoType` is the piece of information you want to manipulate. The result of this functions varies greatly for different `TStatInfoType`s. The parameter `statMessage` is mandatory and is a string used for the statistics, its meaning depends on the `TStatInfoType`. The parameter `teamName` contains the name of a team which is relevant to the chosen stat. This parameter is not always required, this also depends on `TStatInfoType`.

  * As the game engine send stats to the frontend at the end of the game one should send her stats when the game is going to finish and right before the call of `EndGame()`. (Note: Stats are sent from the engine in `CheckForWin`. If conditions are met (win or draw) then `SendStats(uStats)` is called.)
