How to get the transferred quantity with creep.transfer ?


  • Hello,

    I'm trying to get the exact energy quantity transferred during a creep.transfer().

    How can I get this value ?

    I tried, without success :

    energy_berfore = creep.carry.energy;
    creep.transfer(...)
    energy_after = creep.carry.energy;

    but both value before and after are always equals... So, it doesn't work ! 😞

     


  • After calling creep.transfer(...) the operation is just scheduled to be executed at the current tick (see engine descriptions, http://support.screeps.com/hc/en-us/articles/203032752-Understanding-game-loop-time-and-ticks), so inner states of all objects wont change until next tick.

    Seems like the workaround (without exact amount specifying, 3rd argument) looks like:

    let result = creep.transfer(obj, resource);
    let transferred = result === OK ? Math.min(creep.carry[resource], /*obj.emptySpace*/) : 0;

    Dunno why u gonna do that, looks monstrous 😃
