Alex:
function LevelSetup()
Called once at the start of the game - use it to set up asteroids and stuff.
Example:
(click to show/hide)
--- Code: ---function LevelSetup()
SetBackdropColour(237,220,198)
Globals.Asteroids.MaxTrees=0
Globals.Asteroids.MinRadius=85
Globals.Asteroids.MaxRadius=800
Globals.Asteroids.RadiusPowerRule=1.5
Globals.Asteroids.MinSendDistance=2500
Globals.Asteroids.MaxSendDistance=4000
Globals.Asteroids.SendPowerRule=2.5
Globals.G.MinAsteroidSeparation = 500
AddAsteroidRing(4, 0, 0, 900, 150)
a = GetAsteroid(0)
a.Owner = 1
a:AddSeedlings(4)
a = GetAsteroid(1)
a.Owner = 0
a:AddSeedlings(4)
a:Reveal(1)
a = GetAsteroid(2)
a.Owner = 1
a:AddSeedlings(4)
a:Hide(1)
a = GetAsteroid(3)
a.Owner = 1
a:AddSeedlings(4)
a:Hide(1)
end
--- End code ---
function LevelLogic()
Called as a coroutine. Put in while loops with coroutine.yield() in them to hold up your script.
Example:
(click to show/hide)
--- Code: ---function LevelLogic()
Pause()
MessageBox("Starting message\n\nThis message pops up before the level begins.")
WaitDialog()
Unpause()
player = GetEmpire(1)
while player.NumSeedlings <= 15 do
coroutine.yield()
end
Pause()
MessageBox("Ending message\n\nYou totally won the level.\n\nGo you.")
WaitDialog()
Unpause()
Quit()
end
--- End code ---
function LevelDraw()
Optional. Called every time the game draws to the screen. Fill it with your lovely drawing code. Check the script examples thread for an example.
function OnAsteroidTaken(id, owner)
This is optional but if defined will be called whenever an asteroid changes hands. Use it to check for specific asteroids being taken over by specific teams, or whatever you like.
(click to show/hide)
--- Code: ---function OnAsteroidTaken(id, owner)
if id == 1 then MessageBox("Asteroid "..id.." was taken by faction "..owner..".") end
end
--- End code ---
function OnAsteroidRevealed(id, owner)
This is optional but if defined will be called whenever an asteroid is revealed to an owner. So when you discover an asteroid, this will be called with the id of the asteroid and owner 1, for example.
(click to show/hide)
--- Code: ---function OnAsteroidRevealed(id, owner)
if id == 1 then MessageBox("Asteroid "..id.." was discovered by faction "..owner..".") end
end
--- End code ---
Alex:
Let's say you have an Asteroid called a. To call functions on a, you use the colon like so
--- Code: ---a:AddTrees(1,2)
--- End code ---
and to set fields you use the dot like so
--- Code: ---a.Owner = 3
--- End code ---
These are the most important functions and fields available to you as a scripter (there are tons more but listing them all would take ages and confuse people):
Asteroids
Function nameReturn valueDescriptionMoveBy(float, float)nilMoves the asteroid by the given offset.MoveTo(float, float)nilMoves the asteroid to the given position.GetNumSeedlings()intCounts the number of seedlings present at the asteroid.GetNumSeedlings(int faction)intCounts the number of seedlings present at the asteroid belonging to the given faction/empire.GetNumSeedlingsExcluding(int faction)intCounts the number of seedlings present at the asteroid, excluding seedlings from the given faction.GetNumFlowers(int faction)intCounts the number of flowers present at the asteroid belonging to the given faction/empire.GetNumMines(int faction)intCounts the number of mines present at the asteroid belonging to the given faction/empire.GetFlower(int faction)FlowerGets one of the flowers of the given faction present on the asteroid.

Will also affect any trees currently planted here - if they are currently not going to grow a flower (as this is decided when they are created), they will "roll the die" again to see if they will grow a flower.GetRandomDefenseTree() and
GetRandomDefenseTree(bool ignoreEnhance) Structure or nilThis gets a random defense tree. If you send in false as the parameter, it will choose a tree without a flower already planted on it. If no tree is suitable the function returns nil.GetRandomDysonTree() and

The tree will "roll the die" again to see if it will grow a flower.AddFlower()Flower/Mine or nilIf the tree is a dyson tree this will add a Flower. If the tree is a Defense tree it will add a Mine. If the tree already has a flower or mine this will return nil.Field nameTypeDescriptionEnhancedboolSets the tree to have been enhanced (to make super seedlings).

Alex:
For reference, here are some standard Lua reference pages online:
Programming in Lua
If you are new to Lua and especiialy if you are new to scripting, at least read the Expressions and Statements sections, preferably also read the Types section, Functions, and Iterators.
Also available is the rather terse and academic official Lua reference.
