Space Invasion 1.2

=== DOCUMENTATION ===

== SCRIPT CONFIGURATION ==
You can configure this script a little bit, you only have to edit the game scheme.
The script makes heavy use of the script parameters, but you can also use some,
but not all, of the other settings in a game scheme.

You CAN use the following options:
- disable girders (highly recommended!)
- disable land objects
- random order
- solid land
- low gravity (makes this game much easier, but this script is probably not optimized for it yet)
- bottom border
- fort mode (just changes the landscape)
- teams start at opposite parts of land
- wind affects almost everything

Those options are also possible, but have no real gameplay effect:
- disable wind
- tag team
- king mode (here it only changes hats, so this is just for fun)
- vampiric (has no real gameplay effect; just for the grapical effect)
- full border (it’s techincally possible, but the script is currently not very well optimized for this mode)

You CANNOT use any other of the on/off options in the game scheme. Those settings are simply discarded by the script.

You also can change the following settings in the game scheme:
- time per round (very important)
- script parameters, see below

The other settings are technically possible, but their effect is limited:
- damage percentage
- mines/air mines (they don’t harm the active hedgehog, however)
- number of barrels

All other variables are discarded, the script forces its own settings.
There will be never Sudden Death, any crate drops, any mines and any
barrels.


== SCRIPT PARAMETERS ==
This script can be configured mostly with the script parameters.
The script parameters are specified in a key=value format each,
and each pair is delimeted by a comma.
All values must be integer of 0 or higher. All values are optional
and have a default if unspecified

List of parameters:
- rounds: Number of rounds (default: 3)
- shield: Amount of shield you start with (default: 30)
- barrels: Amount of ammo (barrels) you start with (default: 5)
- pings: How many time you can use the radar per round (default: 2)
- barrelbonus: How many barrels you get for collecting/destroning a green invader (default: 3)
- shieldbonus: How much shield you get for collecting/destroying a purple invader (default: 30)
- timebonus: How many seconds you get for killing a drone (red) (default: 4)
- forcetheme: If set to false, the game will use your chosen theme instead of forcing EarthRise
-             Please note that the game may not be able to be played in some themes if the sky
               color is very bright (i.e. Bath)

Example input for the field “Script parameters”:

rounds=5
>>> 5 rounds, everything else is default

forcetheme=false
>>> Makes the game use whatever thme

shield=0, barrels=3, pings=0
>>> no shield, no radar pings and only 3 barrels (could be some hard mode)

(empty string)
>>> Use defaults for everything


-- VERSION HISTORY
----------------
-- version 0.1
----------------
-- conversion of tumbler into space invasion
-- a million and one changes
-- bells and whistles

----------------
-- version 0.2
----------------
-- code slowly getting cleaner, it still looks like a spaghetti monster tho
-- lots of console tracking :/
-- all visual gears are now compulsary (will probably revert this)
-- implemented fMod to try combat desyncs and bring this in line with dev

----------------
-- version 0.3
----------------
-- values of scoring changed to 3:10, and now based on vCircScore
-- time gained from killing a red circ increased from 3 to 4
-- circles now spawn at a distance of at least 800 or until sanity limit
-- roundsLimit now based off MinesTime (kinda, its an experiment)

-----------------
--0.4
-----------------
-- commented out a lot of WriteLnToConsoles (dont need them at this point)
-- added some different WriteLnToConsoles
-- changed some of the collision detect for explosives in checkvarious()

-----------------
--0.5
-----------------
-- added implementation for a projectile shield
-- added a "bonus" orange invader that partially recharges player shield
-- added a tough "blueboss" blue invader
-- expanded user feedback
-- circles now have health and are capable of being merely "damaged"

--0.7
-----------------
-- added PlaySound(sndSuddenDeath) when ammo gets depleted
-- added an extra "Ammo Depleted" note if user presses fire while empty
-- specified how much shield power is gained on shield powerup collection
-- changed odds for circles AGAIN, ammo is now sliiightly more common
-- switched most of the explosions/smoke effects back to non-critical vgears (with a few exceptions)
-- tumbletime is now based off turntime and is variable
-- delete explosives in DeleteFarFlungBarrel rather than explode them on map boundaries to save on performance
-- utilized the improved AddCaption to tint / prevent overrides
-- temporarily disabled bugged sort that displays teams according to their score
-- reluctantly changed the colour of the bonus circ to purple
-- standarized point notation
-- added some missing locs
-- commented out remaining WriteLnToConsoles for the meanwhile with the prefix "nw"

------------------------
-- time for more 'EXPERIMENTS' mwahahahahahaha D:
-- (hopefully) balanced Shield Miser
-- bosses are no longer a redunkulous 50 points, but toned down to 30
-- experimental radar (it's INTERACTIVE and math-heavy :D) (visual gears are safe... right? D:)

]]

--------------------------
-- TODO list: notes for later
--------------------------
-- imitate winning animation at end instead of just ending the game

-- add support for other world edges (they are currently disabled)

-- maybe add a check for a tie, IMPOSSIBRU THERE ARE NO TIES
-- more achievements?
-- more just-for-fun awards (for stats screen)

-- if more weps are added, replace primshotsfired all over the place

-- look for derp and let invaders shoot again

-- more weps? flamer/machineballgun,
-- some kind of bomb that just drops straight down
-- "fire and forget" missile
-- shockwave

-- some kind of ability-meter that lets you do something awesome when you are
-- doing really well in a given round.
-- probably new kind of shield that pops any invaders who come near

-- fix game never ending bug
-- fix radar
-- new invader: golden snitch, doesn't show up on your radar

-- maybe replace (48/100*vCircRadius[i])/2 with something better
