-- RACER
-- a crazy, map-independant racing script
-- by mikade
-----------------------------------------

-----------------------------------
--0.1: with apologies to tumbler
-----------------------------------
-- added tumbler movement system
-- added weapon systems
-- added timer to stop tumbler
-- added racer circle arrays
-- added changing of circs on contact
-- added a "track complete" etc

-----------------------------------
--0.2: for your racing convenience
-----------------------------------

-- added resurrection
-- added team tracking
-- added proper scoring (hopefully, finally)
-- changed showmission icons to match feedback
-- changed circles to be netural colours, and then change to team col
-- cleaned up code
-- cleaned up gameplay: removing control on resurrect, trackcomplete, maxpointset etc
-- improved player feedback: race record, clan record, no record etc.

-----------------------------------
--0.3: user-requested features
-----------------------------------

-- hogs now start at the location of the first waypoint \o/
-- added sticky camera. Hog will no longer lose focus on explosions etc.
-- increased maximum complexity for tracks

-----------------------------------
--0.4: user-requested features
-----------------------------------

-- added movement trail
-- removed exploder weapon
-- removed mortar weapon

-----------------------------------
-- 0.5 gaudy feature experimentation
-----------------------------------
-- added a booster
-- added flame trail for booster
-- added and removed dx/dy on mortar launch
-- added and removed keypress-based mortar fire
-- changed mortar for a gtShell, probably more useful for tunneling
-- added dx/dy *2 shell fire

----------------------------------
-- 0.6 modesty / display mod
----------------------------------
-- author branding removed
-- version numbers removed

-----------------------------
-- SCRIPT BEGINS
