maybe bug in findClosestByPath and findClosestByRange


  • Room W25S21. I call
    var exits = Game.map.describeExits(pos.roomName);
    console.log(JSON.stringify(exits));
    gives {"1":"W25S20","5":"W25S22","7":"W26S21"}

    There is a energy source 55db3189efa8e3fe66e04b78 at (5,10). When I do
    pos = new RoomPosition(5,10,"W25S21");
    result1 = pos.findClosestByPath(exits[7]);
    result2 = pos.findClosestByRange(exits[7]);
    console.log("path result", result1, "range result", result2);
    gives null null

    I might be confused, but there might be a bug here also.


  • Those functions expect an array of either RoomPosition or RoomObject objects as an argument, you are passing in a string ("W26S21").

    Instead of using describeExits and passing that to findClosestByPath, you could try using [Room.find](http://support.screeps.com/hc/en-us/articles/203079011-Room#find) with the FIND_EXIT_TOP, FIND_EXIT_BOTTOM etc as the first parameter which should give you all the exit tiles in that particular direction, and then passing the result of the find to findClosestByPath.

    Thanks for your help.

    findClosestByPath takes either a number or array. The number parameter is a FIND_?? constant. From API reference I am passing one of

    FIND_EXIT_TOP: 1,
    FIND_EXIT_RIGHT: 3,
    FIND_EXIT_BOTTOM: 5,
    FIND_EXIT_LEFT: 7,

    I am actually scouting a source in a remote room to see if it is economic to harvest so I do not necessarily have access to a room object. In fact, here I am creating a function to calculate the exact distance between any two points. Hence I really want to only use RoomPosition and Map methods.

    The code works mostly but for this one source object, both findClosestByPath and findClosestByRange seem to be failing. Ok, I will spend some more time debugging the code and maybe the problem will go away.
