Update: it didn't work. my creeps are still just spawning and not doing anything.

Ok thank you! I'll run it through in simulator mode and see whether it works.

So i have a problem. I recently got invaded by an NPC, and my attackers are supposed to spawn whenever there is a hostile creep in the room. However, all they do is spawn and they don't move. Can anyone help?

var roleAttacker = {

/** 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 hostile = creep.pos.findClosestByRange(FIND_HOSTILE_CREEPS);
        if(hostile) {
            if(creep.attack(hostile[0] == ERR_NOT_IN_RANGE) 
                creep.moveTo(hostile[0])
                creep.attack(hostile);
        }
    }
}

} module.exports = roleAttacker

I also got this weird error that doesn't tell me where my code error is, but just won't let my code run.
