The following functions allow to save data per game, team and unit. The advantage of it is that it can be read from anywhere (even from LuaUI and AIs!)
String values are new since 95.0.

Spring.GetGameRulesParam ( number ruleIndex | string ruleName )
return: nil | number value | string value

Spring.GetGameRulesParams ( )
return: nil | { [ruleName1] = number value1 | string value1, ... }

Spring.GetTeamRulesParam ( number teamID, number index | string ruleName )
return: nil | number value | string value

Spring.GetTeamRulesParams ( number teamID )
return: nil | { [ruleName1] = number value1 | string value1, ... }

Spring.GetUnitRulesParam ( number unitID, number index | string ruleName )
return: nil | number value | string value

Spring.GetUnitRulesParams ( number unitID )
return: nil | { [ruleName1] = number value1 | string value1, ... }

Spring.GetFeatureRulesParam ( number featureID, number index | string ruleName )
return: nil | number value | string value

Spring.GetFeatureRulesParams ( number featureID )
return: nil | { [ruleName1] = number value1 | string value1, ... }

Mod-/Map-Options

Spring.GetModOptions ( )
return: nil | { "keyName1" = string "value", "keyName2" = string "value", ... }

Spring.GetMapOptions ( )
return: nil | { "keyName1" = string "value", "keyName2" = string "value", ... }

Warning: boolean values are not transfered from C to Lua correctly. For this reason the respective option has to be converted to a number and checked accordingly via an IF statement as shown below:

if (tonumber(Spring.GetModOptions.exampleOption) == 1) then...end

The following check therefore is insufficient!

if (Spring.GetModOptions.exampleOption) then...end

Speed/Time

Spring.GetGameSpeed ( )
return: number userSpeedFactor, number speedFactor, bool paused

As of 98.0 moved to Lua_UnsyncedRead due to desyncs in replays/demos

      }, ...
   }

Spring.GetTeamLuaAI ( number teamID )

Spring.GetUnitPiecePosDir

 ( number unitID, number pieceNum ) -> nil | number posX, number posY, number posZ,
   number dirX, number dirZ, number dirY

Returns piece position and direction in world space. The direction (dirX, dirY, dirZ) is not necessarily normalized. The position is defined as the position of the first vertex of the piece and it defines direction as the direction in which the line from the first vertex to the second vertex points.

Spring.GetUnitPieceMatrix

 ( number unitID, number piece ) -> { [1] = number, ... , [16] = number }

Spring.GetUnitScriptPiece

 ( number unitID [, number scriptPiece ] )
  -> nil | { scriptPieceNum = number modelPieceNum } | number modelPieceNum

This functions translate the COB ScriptPiece numbers into the ModelPiece numbers (the set of ScriptPieces is a subset of the ModelPieces, means #ScriptPieces <= #ModelPieces), which is used in all other functions (the "number piece" means always the modelpiece). So if you get via Cob2Lua a pieceID you have to translate it with this function. Btw the COB ScriptPiece number is equal with the piece position in the piece definition in your cob/bos.

Spring.GetUnitScriptNames

 ( number unitID )
  -> { "cobpiecename1" = ScriptPieceNum1, ... , "cobpiecenameN" = ScriptPieceNumN }

        "ctrl"     = boolean,
        "shift"    = boolean,
        "right"    = boolean,
        "internal" = boolean,
        "meta"    = boolean
      }
    }, ...

        "internal" = boolean,
        "meta"    = boolean
      }
    }, ...
  }

Spring.GetFactoryCounts (used to get the buildqueue of a factory, seems screwed o_O)

 ( number unitID [, number count [, boolean addCMDs ] ] ) -> nil | commandQueueTable = {
    [2] = { [number unitDefID | number -cmdID] = number count }, ...

Spring.GetGrass

 ( number x, number z ) -> number 0 | 1

where x & z are in worldspace coordinates

Test Orders

Spring.TestMoveOrder

 ( number unitDefID, number x, number y, number z) -> boolean validMove

New in version 95.0 parameters now are:

   number unitDefID,
   number pos.x, number pos.y, number pos.z
   [, number dir.x
   [, number dir.y
   [, number dir.z
   [, boolean testTerrain
   [, boolean testObjects
   [, boolean centerOnly ]]]]]]
   ) --> boolean

Spring.TestBuildOrder

 ( number unitDefID, number x, number y, number z, number facing)
   -> number blocking [,number featureID]

 blocking can be:
   0 - blocked
   1 - mobile unit in the way
   2 - free  (or if featureID is != nil then with a blocking feature that can be reclaimed)
 facing can be:
   0, "s", "south"
   1, "e", "east"
   2, "n", "north"
   3, "w", "west"

Spring.Pos2BuildPos optional param facing supported in 0.83 and later

 ( number unitDefID, number x, number y, number z[, number facing] ) 
   -> nil | number x, number y, number z

PathFinding

Spring.GetUnitEstimatedPath

 ( number unitID ) -> nil | {
    [1] = { x,y,z }, ...
  },{
    [1] = startIdxOfDetailedPath,
    [2] = startIdxOfDetailedEstimatedPath1,
    [3] = startIdxOfDetailedEstimatedPath2,
  }
 GetUnitEstimatedPath() returns 2 tables:
   1 table the waypoints and 1 table with indices (in the waypoint table)
   when a new (more lazy) pathfinding algorithm  begins.
   So the waypoint table contains 3 different levels of details.

LOS

Spring.IsPosInLos

 ( number x, number y, number z, number allyID ) -> boolean

Spring.IsPosInRadar

 ( number x, number y, number z, number allyID ) -> boolean

Spring.IsPosInAirLos

 ( number x, number y, number z, number allyID ) -> boolean

Spring.GetPositionLosState jammed new in 95.0

 ( number x, number y, number z [, number allyID] )
   -> boolean LosOrRadar, boolean inLos, boolean inRadar, boolean jammed

jammed indicates if a position is actively being radar- or sonar-jammed by any allyteam

Spring.GetClosestValidPosition //NOT FINISHED YET

 ( number unitDefID, number x, number z, number r ) -> nil

Projectiles

Spring.GetProjectilesInRectangle

( number xmin, number zmin, number xmax, number zmax
  [, boolean excludeWeaponProjectiles
  [, boolean excludePieceProjectiles] ] )
  -> nil | projectileTable = { [1] = number projectileID, etc... }

Spring.GetProjectileOwnerID New in version 99.0

  (number projectileID) -> nil | number unitID

Spring.GetProjectileTeamID New in version 99.0

  (number projectileID) -> nil | number teamID

Spring.GetProjectileDefID

  (number projectileID) -> nil | number weaponDefID
 using this to get a weaponDefID is HIGHLY preferred 
 to indexing WeaponDefNames via GetProjectileName

Spring.GetProjectileName

 ( number projectileID ) -> nil | string name

Spring.GetProjectileType

 ( number projectileID ) -> nil | boolean weapon, boolean piece

Spring.GetProjectileTarget

 ( number projectileID )
 Pre 95.0:  -> nil | number targetID, string targetTypeStr
 Post 95.0: -> nil | [number targetTypeInt, number targetID | table targetPos = {x, y, z}]

 targetTypeStr can be one of: 
   'u' - unit
   'f' - feature
   'p' - projectile
 while targetTypeInt is one of:
   string.byte('g') := GROUND
   string.byte('u') := UNIT
   string.byte('f') := FEATURE
   string.byte('p') := PROJECTILE

Spring.GetProjectileIntercepted New in version 99.0

 ( number projectileID ) -> nil | boolean isBeingIntercepted

Spring.GetProjectilePosition

 ( number projectileID ) -> nil | number px, number py, number pz

Spring.GetProjectileVelocity

 ( number projectileID ) -> nil | number vx, number vy, number vz
 New in version 95.0: returns (targetPos - startPos) for Beamlasers and similar weapons

Spring.GetProjectileGravity

 ( number projectileID ) -> nil | number gravity

Spring.GetPieceProjectileParams New in version 95.0

 ( number projectileID ) -> nil |  number explosionFlags, number spinAngle, 
 number spinSpeed, number spinVector.x, number spinVector.y, number spinVector.z
 Where explosionFlags use binary flags with the following integer equivalents: 
  more info here
  SHATTER = 1,  EXPLODE = 2, EXPLODE_ON_HIT = 2, FALL = 4, SMOKE = 8, FIRE = 16
  NONE = 32, NO_CEG_TRAIL = 64, NO_HEATCLOUD = 128

Spring.GetProjectileTimeToLive New in version 99.0

 ( number projectileID ) -> nil | number ttl

Spring.GetProjectileDirection New in version 95.0

 ( number projectileID ) -> nil | number dir.x, number dir.y, number dir.z

Spring.GetProjectileSpinAngle Deprecated in 95.0

 ( number projectileID ) -> nil | number angle

Spring.GetProjectileSpinSpeed Deprecated in 95.0

 ( number projectileID ) -> nil | number spinSpeed

Spring.GetProjectileSpinVec Deprecated in 95.0

 ( number projectileID ) -> nil | number x, number y, number z

Spring.GetProjectileDamages New in version 101.0

 ( number unitID, number weaponNum, string tag ) -> nil | number
 `tag` can be:
 "paralyzeDamageTime"
 "impulseFactor"
 "impulseBoost"
 "craterMult"
 "craterBoost"
 "dynDamageExp"
 "dynDamageMin"
 "dynDamageRange"
 "dynDamageInverted"
 "craterAreaOfEffect"
 "damageAreaOfEffect"
 "edgeEffectiveness"
 "explosionSpeed"
 - or -
 an armor type index to get the damage against it.
