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”).

This is used while a special hand-drawn map is loaded. The engine is building these hand-drawn maps by reading points from the map definition. Optionally, some of these points may be “special”. These are not actually drawn on the map, but are used to store additional information for a position on the map. Special points currently need to be added manually in the map, the in-game editor is not able to add those yet (as of 0.9.23).

This attempts to create a new visual gear at position x,y (measured from top left) of kind `visualGearType` (see [VisualGearTypes Visual Gear Types]).  Visual gears are decorational objects which are usually used for purely decorational graphical effects.  They have no effect on gameplay.  Visual gears are not the same as gears, but they share some similarities.

The function returns the `uid` of the visual gear created or `nil` if creation failed.  There is no guarantee that a visual gear will spawn.  *IMPORTANT: Do not rely on visual gears to spawn*. *Always* be prepared for this function to return `nil`.

Set `critical` to `true` if the visual gear is crucial to gameplay and must always be spawned when in-game.  Use `false` if it is just an effect or eye-candy, and its creation can be skipped when in fast-forward mode (such as when joining a room).

*NOTE:* Visual gears *must* only be used for decorational/informational/rendering purposes. *Never* use the visual gear's internal state to manipulate anything gameplay-related. Visual gears are not safe for reliable storage and using them as that would lead to strange bugs.

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. If `amount` is `nil` or `0`, the value set by `SetAmmo` is used, or if `SetAmmo` has not been used, it falls back to the weapon scheme's value. If `amount` is equal to or greater than `AMMO_INFINITE`, the amount is infinite.

Returns the `Radius` value for the specified gear. For most [GearTypes gear types] for “projectile” gears (like `gtShell` or `gtGrenade`), the radius refers to the gear's collision radius. This is an invisible circle around the center of the gear which is used for the collision checks. For a few gear types, its radius means something different, see [GearTypes] for a full list.

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.

This allows manipulation of the internal state of the visual gear `vgUid`. If `vgUid` is invalid or the `vgUid` does not refer to an existing visual gear, the function does nothing. Thus, you can safely call this function even if you are not sure if the visual gear actually exists.

Some visual gears interpret these values differently, just like normal gears. See [VisualGearTypes] for details.  Also, most visual gears are not using all possible values, while some values are just ignored.

Sets the elasticity of the specified gear. For most gears, the elasticity determines how strong the gear will bounce after collisions, where higher elasticity is for stronger bounces. Recommended are values between `0` and `9999`.

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.

Attempts to place a rubber with centre points `x`, `y` and a certain orientation, specified by `frameIdx`. The rubber can only be placed in open space and must not collide with anything so this function may fail. It will return `true` on successful placement and `false` on failure.

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:

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.
