---------------------------------------------------------
--- LE CONSTRUCTION MODE 0.7+ (badly adapted from Hedge Editor 0.5)
---------------------------------------------------------
-- a hedgewars gameplay mode by mikade
-- special thanks to all who helped test and offered suggestions
-- additional thanks to sheepluva/nemo for adding some extra hooks

-- (to do)
-- investigate loc not working on addcaptions
-- check for parsecommands before porting to dev
-- test onUpDown more extensively as it may need revision (check for amRubber etc)
-- test localization of weapons and utils and stuff

-- try posistion grenades in Harmer so it blows hogs away from the struc
-- and don't explode too close to the struc

-- additional/previous balance ideas
-- based on your money?
-- based on the number of strucs/gens you own?
-- based on your existing arsenal?
-- limit number of crates spawned per round perhaps (done)
-- limit number of generators?

------------------------------------------------------------------------------
-- SCRIPT PARAMETER
------------------------------------------------------------------------------
-- The script parameter can be used to configure the energy
-- of the game. It is a comma-seperated list of key=value pairs, where each
-- key is a word and each value is an integer between 0 and 4294967295.
--
-- Possible keys:
--- initialenergy: Amount of energy that each team starts with (default: 550)
---                Note: Must be smaller than or equal to maxenergy
--- energyperround: Amount of energy that each team gets per round (default: 50)
--- maxenergy: Maximum amount of energy each team can hold (default: 1000)

-- Example: “initialenergy=750, maxenergy=2000” starts thee game with 750 energy
-- and sets the maximum energy to 2000

------------------------------------------------------------------------------
--version history
------------------------------------------------------------------------------
--v0.1
-- concept test

--v0.2
-- improved documentation (in script and in game)
-- improved localisation (or is it? at any rate, crate placement should now say e.g. Bazooka and not amBazooka)
-- added variable weapon costs (based on the values from Vatten's Consumerism script)

-- added reflector shield (still needs work and balancing)
-- added weapon-filter (probably ok)

-- enabled super weapons like ballgun, rcplane, watermelon, hellish to test balance
-- reduce max money to 1000

--v0.3
-- some /s removed

--v0.4
-- added support for per hog ammo (hopefully)

--v0.5 (dev)
-- added somewhat horribly implemented support for different structure sprites
-- added override pictures for ammo menu
-- added override message on wep select to aid understanding
-- split menu into/between weps/parts: struc, crates, gears
-- add a limit on crates per turn
-- add a limit on extra time per turn
-- add a test level
-- restored rubber placement
-- cleaned up some of the code a bit and removed about 280 lines of code I didn't need, lol

--v0.6 (dev)
-- added magic dance

--v0.7 (pushed to repo)
-- added a cfg file
-- removed another 903 lines of code we weren't using (lol)

--v0.7+ (merged in repo)
-- applied Wuzzy's patches:
--   script parameters: initialenergy, energyperround, maxenergy
--   fix crate costs
--   various minor tweaks and fixes
--   (see commits in official repo)
-- make Construction Mode play well together with fort mode (clan order = fort order)

--------------------------------
-- STRUCTURES LIST / IDEAS
--------------------------------

--Healing Station: heals hogs to 150 life
--Teleportation Node: allows teleporting to any other teleporter nodes
--Bio-filter: explodes enemy hogs
--Respawner: if you have one of these, any slain hogs are resurrected here :D
--Generator: generates energy (used to buy stuff, and possibly later other strucs might have upkeep costs)
--Support Station: allows purchasing of weapons, utilities, and med-crates
--Construction Station: allows purchasing of girders, rubber, mines, sticky mines, barrels
--Reflector Shield: reflect projectiles
--Weapon Filter: kill all equipement of enemy hogs passing through this area.


--to make the grill more attractive make it vaporize flying saucers
--and also rope, and maybe incoming gears

-- make healing thing also cure poison
-- maybe make poison more virulent and dangerous

--(not implemented / abandoned ideas)
-- Core: allows construction of other structures.
-- Automated Turret (think red drones from space invasion)
-- Canon (gives access to 3 fireballs per turn while near)
-- something that allows control of wind/water
-- Gravity Field generator : triggers world gravity change

-- structures consume power over time and
-- maybe you can turn structures OFF/ON, manually to save power.

-- hacking
-- allow hacking of structures, either being able to use enemy structures,
-- or turning a team's structures against them.

-- pylons
-- allow hogs to put down a pylon-like gear which then allows the core
-- to place other structures/objects within the pylon's sphere of influence
-- this would allow aggressive structure advancement

-- resouce mining?
-- you could designate something like mines, that you could get close to,
-- "pick up", and then "drop" back at a central location to simulate
-- resource mining. bit complicated/meh, normal power generators probably easier

-- it would be cool to have a red mask we could apply over girders
-- that would indicate they were Indestructible
