Lua Call-Ins, with parameters

Here are the known reserved parameter values for all Lua Call-Ins. If you add new Call-Ins to Spring, please document them here.

Commands, general-purpose:

Shutdown() --> none.

LayoutButtons() --> unknown, please document.

ConfigureLayout() --> "command".

CommandNotify() --> "id, params, options", where id = the CommandID

KeyPress() --> "key, mods, isRepeat", where key = keymap, mods = SHIFT, etc.

KeyRelease() --> "key"

MouseMove() --> "x, y, dx, dy, button"

MousePress() --> "x, y, button"

MouseRelease() --> "x, y, button"

IsAbove() --> "x, y" where x,y = screen coordinates.

GetTooltip() --> "x, y" where x,y = screen coordinates. Returns WorldTooltip.

AddConsoleLine() --> "msg, priority"

AllowCommand() --> "unitID, unitDefID, unitTeam, cmdID, cmdParams, cmdOptions, cmdTag, synced"

CommandFallback() --> "unitID, unitDefID, unitTeam, cmdID, cmdParams, cmdOptions, cmdTag"

AllowUnitTransfer() --> "unitID, unitDefID, oldTeam, newTeam, capture"

AllowUnitBuildStep() --> "builderID, builderTeam, unitID, unitDefID, part"

AllowFeatureCreation() --> "featureDefID, teamID, x, y, z"

AllowFeatureBuildStep() --> unknown, please document.

AllowResourceLevel() --> "teamID, res, level"

AllowResourceTransfer() --> "teamID, res, level"

Unit-Specific:

UnitPreDamaged() --> "unitID, unitDefID, unitTeam, damage, paralyzer, weaponID, attackerID, attackerDefID, attackerTeam"

UnitDamaged() --> "unitID, unitDefID, unitTeam, damage, paralyzer, weaponID, attackerID, attackerDefID, attackerTeam"

UnitCreated() --> "unitID, unitDefID, teamID" ... I hope that's self-explanatory

UnitFinished() --> "unitID, unitDefID, teamID"

UnitFromFactory() --> "unitID, unitDefID, unitTeam, factID, factDefID, userOrders"

TerraformComplete() --> "unitID, unitDefID, unitTeam, buildUnitID, buildUnitDefID, buildUnitTeam"

UnitCmdDone() --> "unitID, unitDefID, unitTeam, cmdID, cmdTag"

Drawing:

• DrawGenesis() --> none. Don't render here.

• Spring draws the sky, the map, some water types, and unit selection.

• DrawWorldPreUnit() --> none.

• Spring draws units, features, some water types, cloaked units, and the sun.

• DrawWorld() --> none.

• Spring draws command queues, 'map stuff', and map marks.

Each unit might also have a DrawUnit call, enabled here.

DrawUnit(unitID,DrawMode)
With enum DrawMode {
notDrawing = 0,
normalDraw = 1,
shadowDraw = 2,
reflectionDraw = 3,
refractionDraw = 4
};

DrawScreenEffects() --> "vsx, vsy" where vsx, vsy are screen coords.

DrawScreen() --> none.

DrawInMiniMap() --> "sx, sy" where sx,sy are values relative to the minimap's position and scale.

DrawWorldShadow() --> none.

DrawWorldReflection() --> none.

DrawWorldRefraction() --> none.

Game Events:

Explosion() --> "weaponID, px, py, pz, ownerID"

ShockFront() --> "power, dx, dy, dz"

GameFrame() --> "frameNum"

CobCallback() --> unknown, marked FIXME.

GroupChanged() --> "groupID" where groupID is the value of Group whose table value changed.

WorldTooltip() --> "ttType, data1, data2, data3" special, should be documented in detail.

GamePreload() --> none.

GameStart() --> none.

GameOver() --> none.

TeamDied() --> "TeamID" where TeamID = the team that has been eliminated.
