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.

-- OrbitBot, a simple robot that finds the nearest TestItem and orbits it
-- Note that this relies on line-of-sight navigation, so only good for open levels

-- !!! WILL ONLY WORK WITH RELEASE VERSION OF BITFIGHTER 011 AND ABOVE !!!
