## What is This?

This is a reference for writing Lua scripts to work in Aleph One. It lists every trigger and table available to Lua scripts. It is expected that Lua functionality will grow in Aleph One, and as it does, so will this document. Not everything here is completely documented, and any help fixing that would be appreciated.

This is not a reference for Lua itself - see lua.org for that.

## Running a Script

There are three ways to get a script to run - by embedding it in a level, by selecting a solo script in the Environment Preferences, or by selecting a script at the gather network game dialog.

To embed a script in a level, use a tool such as Atque. Use embedded Lua scripts only for map specific features, not for modifying game types. For instance, it may be tempting to embed the latest version of the Lua CTF script in a map designed only for playing CTF; however, this would prevent the user from using a later version of CTF if it were to come out, or from using another net script that works on CTF maps. Some older scenarios use Lua scripts in TEXT resources, but this is no longer recommended since they are not transmitted in net games.

To use a solo script, check the "Use Solo Script" box in Environment Preferences, and choose the script file to use.

To use a script via the network game dialog, put then script in a text file with the extension .lua. Then, at the gather network game dialog, select "use script", then select your script file.

## Units

The unit for distance we use is World Units (WU) These are the same values you'd see in Forge or with F10 location display, and 1/1024 of what A1 uses internally and what you'd see in Pfhorte.

Units for speed are . . . well let's say they're messy. :) Lua speeds are expressed in World Units per tick (a tick is 1/30 of a second). Forge claims to use WU per sec, but it actually uses 0.87890625 WU per sec (which equals 30 internal units per tick). The following example illustrates the various conversions:

- Actual: 7.5 World Units per second
- A1 internal: 256 units per tick (7.5 * 1024 / 30)
- Lua: 0.25 WU per tick (7.5 / 30)
- Forge: 8.53 "WU per second" ((7.5 * 1024 / 30) / 30)

## Local Player

A few variables are marked "local player." These variables will always do the right thing when written to, but when reading, will only return a useful result if the player they belong to is "local." In net games, there is a separate copy of each Lua script running on each player's computer, and the player is "local" only to his copy of the script.

So, the only local player variables the script running on player 4's machine will be able to read from are the ones in Players[4]. For his script, the value of Players[1].zoom_active, for example, will return nil. If this confuses you, it might be better to avoid reading from any variable marked "local player."

## Loading Collections

A Lua script can ask for the engine to load collections it might otherwise not load; for instance, in order to be able to spawn defenders and compilers on a map that might not have them otherwise, add the indices for those collections to the global table CollectionsUsed:

    CollectionsUsed = { 10, 16 }

## Persistence

Lua scripts are only active during a single level. If the user jumps to a new level, or restores from a saved game, the script is restarted in a clean state.

It is now possible to pass data across level jumps, by using the Game.restore_passed() function. This function will restore any custom fields (see the "Custom Fields" section of "Using Tables" below) in the Players or Game tables that were set immediately prior to the last level jump. Note that in order for data to survive multiple level jumps, Game.restore_passed() must be called after each level jump. Game.restore_passed() will not restore data from saved games.

It is also possible to restore data from saved games. The Game.restore_saved() function will restore all custom fields in use at the time the game was saved.

Only numbers, strings, booleans, and tables (including Aleph One's built-in userdata tables) can be restored.

# Triggers

These are functions scripts can define which Aleph One will call at specific times or events. For example, to regenerate health: Triggers = {} function Triggers.idle() for p in Players() do if p.life < 150 and not p.dead then p.life = p.life + 1 end end end Calling Triggers = {} at the beginning of the script removes the compatibility triggers installed for old Lua scripts, speeding up execution of new scripts.

Triggers
  .init(restoring_game)

    at beginning of level

    - restoring_game: true if restoring from a saved game
  .cleanup()

    at end of the level

    primarily this is intended as a last chance for changing netgame scores before the postgame carnage report.

  .idle()

    at each tick, before physics and such

  .postidle()

    at each tick, after physics and such, but before rendering

  .start_refuel(class, player, side)

    whenever a player starts to use a refuel panel

  .end_refuel(class, player, side)

    whenever a player stops using a refuel panel

  .tag_switch(tag, player, side)

    whenever a player uses a tag switch

    not called when a projectile (e.g., fists) toggles a tag switch

    side is only valid in version 20111201 and newer

  .light_switch(light, player, side)

    whenever a player uses a light switch

    not called when a projectile (e.g., fists) toggles a light switch

    side is only valid in version 20111201 and newer

  .platform_switch(polygon, player, side)

    whenever a player uses a platform switch

    - polygon: polygon of the platform being toggled

    not called when a projectile (e.g., fists) toggles a platform switch

    side is only valid in version 20111201 and newer

  .projectile_switch(projectile, side) 20111201

    whenever a projectile toggles a switch

    - projectile: projectile that toggled the switch
    - side: side containing switch being toggled
  .terminal_enter(terminal, player)

    whenever a player starts using a terminal

  .terminal_exit(terminal, player)

    whenever a player stops using a terminal

  .pattern_buffer(side, player)

    whenever a player uses a pattern buffer

  .got_item(type, player)

    whenever a player picks up an item

    also whenever a player gets an item when a script calls .items.add()

  .light_activated(light)

    whenever a light is activated or deactivated

  .platform_activated(polygon)

    whenever a platform is activated or deactivated

  .player_revived(player)

    whenever a player revives (presumably only happens in a netgame)

  .player_killed(player, aggressor_player, action, projectile)

    whenever a player dies

    - aggressor_player: the player who killed player, possibly himself (suicide) (can be nil)
    - action: dying soft, dying hard, or dying flaming
    - projectile: the projectile that delivered the final blow (can be nil)
  .player_damaged(victim, aggressor_player, aggressor_monster, damage_type, damage_amount, projectile)

    whenever a player has taken damage, but before he dies if applicable. The player's suit energy or oxygen may be negative when this trigger is called; if it still is when the trigger returns, it will be set to 0. The player's suit energy is tested again after this trigger returns, so a script may prevent a player's death

    - aggressor_player: player who got the kill (can be nil)
    - aggressor_monster: monster that got the kill (can be nil)
    - damage_type: e.g. "fists"
    - damage_amount: the amount recently subtracted from the player. If "oxygen drain", damage_amount was assessed against player's oxygen; otherwise against player's suit energy
    - projectile: the projectile that delivered the damage (can be nil)
  .monster_damaged(monster, aggressor_monster, damage_type, damage_amount, projectile) 20100118

    whenever a monster is damaged, but before it dies if applicable. The monster's vitality may be negative when this trigger is called. Ther monster's vitality will be tested again after this trigger returns, so a script may prevent a monster's death

    - aggressor_monster: the monster that caused the damage (can be nil)
    - damage_type: e.g. "fists"
    - damage_amount: the amount recently subtracted from the monster's vitality
    - projectile: the projectile that delivered the damage (can be nil)
  .monster_killed(monster, aggressor_player, projectile)

    whenever a monster dies

    - aggressor_player: player who killed it (can be nil)
    - projectile: projectile that delivered the final blow (can be nil)

    called after a monster has taken lethal damage, but before it's removed from the monster list

    you can use this to find out when a monster created with new_monster dies, but a monster discovered by Polygons.monsters() may have already taken lethal damage, so you may need to check for that case when using Polygons.monsters()

  .item_created(item)

    whenever an item is created and placed on the ground (or floating) somewhere

    does not trigger on initial item placement because the initial item placement is done before Lua becomes initialised.

  .projectile_created(projectile) 20150619

    whenever a projectile is created

  .projectile_detonated(type, owner, polygon, x, y, z)

    whenever a projectile detonates, after it has done any area of effect damage

# Using Tables

There are numerous tables (technically, userdata) defined in Aleph One which scripts can use to access objects in the game. A complete list is below.

Unless otherwise specified, these tables are only valid inside the trigger calls listed above. Attempting to use them in the main body of a script may cause an error in this version or a future version of Aleph One.

## Custom Fields

In a real Lua table, you can set any field you want. In order to help troubleshooting, Aleph One's userdata tables will only accept the fields listed in the documentation below. However, by prepending an underscore, custom fields can be indexed. These custom fields will be associated with the object until it is destroyed.

    Players[0]._favorite_flavor = "chocolate"

## Index

Each table has a read-only .index variable, that corresponds to the engine's internal index.

    =Players[0].index
    0

## is_ Functions

Aleph One installs a set of boolean functions that can be used to recognize each of the userdata table types. For example, `is_monster(Monsters[1])` returns true. Each of these functions begins with the "is_" prefix.

    this can suppress initial monster placement, if set to false directly when the script is loaded

  .proper_item_accounting 20100118

    When true, the current item counts on the map are updated properly when Lua deletes map items and changes player inventories. This defaults to false to preserve film playback with older scripts. New scripts that manipulate items should always set this to true.

  .nonlocal_overlays Git

    When false, only the local player's overlays are used, and only prints to the local player will be displayed. When true, the overlays and prints of whatever player is currently being viewed will apply. This defaults to false for compatibility with scripts that depend on the old behavior.

  .time_remaining (read-only)

  .scoring_mode

    the current scoring mode (if the gametype is "custom")

  .over (write-only)

    Use this variable to override the game's default scoring behavior. If set to false, the game will not end due to a score limit. If set to true, the game ends immediately. If left unset or if set to nil, the game will end if a score limit is reached. (Note that you cannot prevent the game from ending due to a time limit.)

  .local_random(n)

    returns a random number between 0 and n-1 from Aleph One's original random number generator

    this is a good way to put net games out of sync

# Types and Mnemonics

The string mnemonics listed below can be used for assignment and as arguments to functions. Additionally, Aleph One's Lua interpreter has been modified so that equality comparisons between userdata types and strings are possible.

For example, this script would move all players on the blue team to the red team: for p in Players() do if p.team == "blue" then p.team = "red" end end And this one would damage all major compilers with 10 points of fusion damage: for m in Monsters() do if m.type == "major compiler" then m:damage(10, "fusion") end end Each type has a read-only .index field, which represents the game's internal index: > =ItemTypes["pistol"].index 1 Each type also has a .mnemonic field, which is handy for finding the mnemonic of a given type: > =MonsterTypes["major compiler"].class.mnemonic compiler You can even use the mnemonic field to customize the mnemonics for your scenario. Note that you can only have one string mnemonic per type index: > WeaponTypes["fist"].mnemonic = "puncher" > =WeaponTypes["puncher"].index 0 > =WeaponTypes["fist"] nil If you do this, you should customize them all at the beginning of the script. Changing mnemonics mid-game will confuse anyone who tries to read your script, and probably yourself as well!

# Example Icon

    --[[
    This is  an example  of an  icon  in  the format  used by  Aleph One's  overlay
    functions.
    The first characters  are a digit string  describing the number of  colors. (in
    this example, it's 7.
    The first character that  is not a digit is ignored,  as are all the characters
    following it  that are the same  character. (i.e. I  could use a q instead of a
    newline here.
    Then,  for  every color,  it reads  a character,  followed by  a six-digit  hex
    string,  which is the  HTML-style color corresponding  to that character in the
    image.  After reading this string,  it ignores the next character,  whatever it
    is.
    Once it has  read every color,  it reads all the following characters,  and for
    every character it reads for which a color has defined, it puts that color into
    the icon as the next pixel. Other characters are ignored. (see below.)
    Icons are always 16x16.
