-- map-independant racing script

-- by mikade

-----------------------------------------

-----------------------------------

--0.1: took all the code from crazy racer and scrapped most of it

-----------------------------------

-- Removed tumbler system

-- Removed extra adds like boosters etc

-- Added experimental waypoint placement system

-- More user feedback

-- Reduced race complexity limit to 5 waypoints

-- stop placement at complexity limit reached and end turn

-- guys dont keep racing after dying

-- invulnerable feasibility

-- reverted time keeping method

-- reduced feedback display time

-- colour-coded addcaptions

-- cleaned up code

-- support for more players properly added

-- tardis fix

-- remove airstrikes

-- i think the remainder 0 .456 sec of the tracktime isnt getting reset on newturn

-- update feedback

-------

-- 0.2

-------

-- allow gameflags

-- extend time to 90s

-- remove other air-attack based weps

-- turn off water rise for sd

-------

-- 0.3

-------

-- prevent WP being placed in land

-- prevent waypoints being placed outside border

-------

-- 0.4

-------

-- update user feedback

-- add more sounds
