4. Can't fill all of my extensions

Can't fill all of my extensions


  • Hi everyone, I am really new to screeps so this might sound like a basic issue. My problem is that my Harvesters fill the Spawn with energy and then they only fill 1 extension when there are 4 extensions left empty.

    I was wondering how to fix that issue.

    My code: var roleHarvester = {

    /** @param {Creep} creep **/
run: function(creep) {
    if(creep.store.getFreeCapacity() > 0) {
        var sources = creep.room.find(FIND_SOURCES);
        if(creep.harvest(sources[0]) == ERR_NOT_IN_RANGE) {
            creep.moveTo(sources[0], {visualizePathStyle: {stroke: '#ffaa00'}});
        }
    }
    else {
        var targets = creep.room.find(FIND_STRUCTURES, {
                filter: (structure) => {
                    return (structure.structureType == STRUCTURE_EXTENSION || structure.structureType == STRUCTURE_SPAWN) &&
                        structure.store.getFreeCapacity(RESOURCE_ENERGY) > 0;
                }
        });
        if(targets.length > 0) {
            if(creep.transfer(targets[0], RESOURCE_ENERGY) == ERR_NOT_IN_RANGE) {
                creep.moveTo(targets[0], {visualizePathStyle: {stroke: '#ffffff'}});
            }
        }
    }
}

    };

    module.exports = roleHarvester;


  • let me make sure. Is your problem that you want to fill extension first ?

    If yes, i suggest your change your find targets code, a simple change is

    const target = targets[targets.length - 1]; // take the last target, it must not be spawn

    and then

    if (creep.transfer(target, RESOURCE_ENERGY) === ERR_NOT_IN_RANGE) {
  creep.moveTo(target);
}
