CPU tips and tricks


  • Hello! I was just wondering if anyone has any suggestions on how to save on CPU... I am already reusing creep paths as much as I can, but It seems like no matter what I try, I always have the same error:

    Script execution has been terminated: CPU bucket is empty

    Thanks 😄


  • The biggest saving i found was by replacing Structure.prototype.isActive

        const _isActive = Structure.prototype.isActive;
    Structure.prototype.isActive = function() {
        if (this.structureType === STRUCTURE_CONTAINER || this.structureType === STRUCTURE_ROAD) {
            // Always true for these
            this.isActive = function() { return true };
            return true;
        }
        const room = this.room;
        const roomLevel = (room.memory.level || room.controller.level);
        if (roomLevel === CONTROLLER_MAX_LEVEL) {
            this.isActive = function() { return true };
            return true;
        }
        const curActive = _isActive.call(this);
        this.isActive = function() { return curActive };
        return curActive;
    };

  • Enlarge the harvesters by more WORK parts will save a lot CPU.
