SCRIPT PARAMETER
The script is configured with the script parameter.

Additional configuration in the game scheme is permitted.

The script parameter is a comma-separated list of key=value pairs.

The values are always whole numbers, the keys are listed below.

Key			Default	Description
----------------------------------------------------------------------
spawnbarrels		2	Number of barrels that spawn per turn
spawnmines		4	Number of mines that spawn per turn
ammoflamer		50	Initial fuel/ammo of Flamer
ammobarrel		2	Initial ammo of Barrel Launcher
ammomine		1	Initial ammo of Mine Deployer
minetimerplaced		1000	Mine timer of mines dropped from Mine Deployer (!) in milliseconds
bonustime		25	Bonus time in utility crates, in seconds
bonusflames		800	Flamer fuel bonus in ammo crates
chanceammo		30	Chance (in %) that an ammo crate will drop before a turn
chancetime		50	Chance (in %) that an utility crate (extra time) will drop before a turn


EXAMPLES:

ammoflamer=800, ammomine=5
--> Starts the game with 800 Flamer fuel and 5 Mine Deployer mines.

chancetime=0
--> No clock crates.


GAME SCHEME CONFIGURATION
The script recognizes most game modifiers and settings, but changing the following game modifiers
will have no effect:
- Artillery
- Tag Team
- Shared ammo
- Per-hog ammo
- Place hogs
- Invulnerable
- Reset weapons

------------------------
-- version 0.4
------------------------

-- removed some old code/comments
-- removed both shell and mortar as the primary and secondary weapons
-- the primary weapon is now an explosive(barrel)

-- added support for picking up barrels scattered about the map (backspace)
-- added support for dragging around mines (enter toggles on/off)
-- added support for primary fire being onAttackUp
-- added a trail to indicate when the player has 5s or less left to tumble
-- updated showmission to reflect changed controls and options

------------------------
-- version 0.5
------------------------

-- changed some of the user feedback
-- i can't remember??
-- substituted onAttackUp for onPrecise()
-- brought in line with new velocity changes

------------------------
-- version 0.6
------------------------

-- reduced starting "ammo"
-- randomly spawn new barrels/mines on new turn
-- updated user feedback
-- better locs and coloured addcaptions
-- added tag for turntime
-- removed tractor beam
-- added two new weapons and changed ammo handling
-- health crates now give tumbler time, and wep/utility give flamer ammo
-- explosives AND mines can be picked up to increase their relative ammo
-- replaced "no weapon" selected message that hw serves
-- modified crate frequencies a bit
-- added some simple kill-based achievements, i think

------------------------
-- version 0.7
------------------------

-- a few code optimisations/performance tweaks
-- removed some deprecated code
-- fix a potential spawn bug

-- improved HUD (now shows ammo counts)
-- improved user feedback (less generic messages)
-- colour-coded addcaptions to match hud :)

-- base tumbling time now equals scheme turntime
-- tumbling time extension is now based on the amount of health contained in crate
-- new mines per turn based on minesnum
-- new barrels per turn based on explosives

-- added 2 more achievements: barrel eater and mine eater (like kills, don't do anything atm)
-- slightly increased grab distance for explosives/mines
-- slightly increased flamer velocity
-- slightly decreased flamer volume
-- added a flame vaporiser (based on number of flame gears?)
-- give tumblers an extra 47 health on the start of their tumble to counter the grenade (exp)
-- refocus camera on tumbler on newturn (not on crates, barrels etc)
-- increase delay: yes, yes, eat your hearts out

-- commit log
-- Better HUD
-- Allow more user customization
-- Bugfix for new gear spawns
-- Performance tweaks
-- Variety of small gameplay changes

------------------------
-- version 0.7.1
------------------------

-- redraw HUD on screen resolution change

------------------------
-- version 0.8.0
------------------------
-- Allow detailed configuration with script parameter (see above)
-- Alternative weapon selection with slot keys
--- Slot 1: Barrel Launcher
--- Slot 2: Mine Deployer
--- Slot 3: Flamer
-- Add mine/barrel launch sounds
-- Improved ammo display
-- Denied sound + message when trying to fire empty ammo weapon
-- Slightly better mission description
--- The old hacks by (ab)using MinesNum, Explosives and HealthCaseAmount have been removed
-- Permanently disable some gameflags which currently won't work together with this script (see above)
-- Show flamer ammo as fuel everywhere (no more percentage confusion)

---------------------------
-- some other ideas/things
---------------------------
--[[
-- allow invulnerability mode (currently broken, thus disabled)
-- better barrel/minespawn effects
-- separate grab distance for mines/barrels
-- bug: message color for remaining ammo does not change if two times the same message
   (but in different desired color) is shown in quick succession (i.e. "Out of ammo!" for all weapons)
-- [probably not] make barrels always explode?
-- [probably not] persistent ammo?
-- [probably not] dont hurt tumblers and restore their health at turn end?
