RACER

map-independant racing script

originally by mikade, edited heavily by others

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

Script parameters:

rounds=N

--> The game will be played with N rounds (default: 3)

waypointradius=N

--> The waypoints have a radius of N pixels (default: 450)

maxwaypoints=N

--> The maximum number of waypoints to be placed (default: 8)

teamrope=true

--> The team will be colored in the color of the team.

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

DEVELOPER WARNING - FOR OFFICIAL DEVELOPMENT --

Be careful when editig this script, do not introduce changes lightly!

This script is used for time records on the official Hedgewars server.

Introducing breaking changes means we have to invalidate past time records!
