Hello:

I am beginner, I have just finished the tutorial and I am trying to upgrade the Room Controller, however I realized it is far from the spawn point.

How could shorten the distance to allow the screeps reach it?

I tried by myself to use the Construct tool. I drawed a road from the spawn to the Room Controller. However after spawning a screep with the memory 'builder' and setting its scripts for role.builder as follows:

var roleBuilder = {

/** @param {Creep} creep **/
run: function(creep) {

    if(creep.carry.energy == 0) {
        creep.memory.building = false;
        creep.say('🔄 harvest');
    }
    if(!creep.memory.building && creep.carry.energy == creep.carryCapacity) {
        creep.memory.building = true;
        creep.say('🚧 build');
    }

    if(creep.memory.building) {
        var targets = creep.room.find(FIND_CONSTRUCTION_SITES);
        if(targets.length) {
            if(creep.build(targets[0]) == ERR_NOT_IN_RANGE) {
                creep.moveTo(targets[0], {visualizePathStyle: {stroke: '#ffffff'}});
            }
        }
    }
    else {
        var sources = creep.room.find(FIND_SOURCES);
        if(creep.harvest(sources[0]) == ERR_NOT_IN_RANGE) {
            creep.moveTo(sources[0], {visualizePathStyle: {stroke: '#ffaa00'}});
        }
    }
}

};

module.exports = roleBuilder;

I have found that it does not move. Why?

Thank you for your time and help.
