For reference information on how these robots work, see the Programming Robots section.
IMPORTANT: In order for these bots to work with Bitfighter 011 alpha 2, you will need to update the file "robot_helper_functions.lua" in your Bitfighter install folder. Replace the file's contents with the following:
bot = LuaRobot(Robot) -- This is a reference to our bot function getFiringSolution(item) if(item == nil) then return nil end type = item:getClassID() if(type == nil) then return nil end return bot:getFiringSolution(type, item) end function logprint(msg) bot:logprint(msg) end
JUST AS IMPORTANT In 011 alpha 2, there is a bug in setThrustToPt() that can cause Bitfighter to hang. It will be fixed in alpha 3. Inserting the line:
if(bot:getTime() == 0) then return end
as the first line of your getMove() function will fix the problem.
