bring resources to spawn and extensions

spawns faster creep (4x faster)

/console

Game.spawns['Spawn1'].spawnCreep( [WORK,WORK,WORK,WORK,CARRY,MOVE,MOVE],
    'HarvesterBig',
    { memory: { role: 'harvester' } } );

 

auto spawns creep

since there is no function to see if a creep has died of fatigue, we can count creeps and if they go below a threshold we respawn them

/main

prints on console numbers of currently alive creeps

var roleHarvester = require('role.harvester');
var roleUpgrader = require('role.upgrader');

module.exports.loop = function () {

    var harvesters = _.filter(Game.creeps, (creep) => creep.memory.role == 'harvester');
    console.log('Harvesters: ' + harvesters.length);

    for(var name in Game.creeps) {
        var creep = Game.creeps[name];
        if(creep.memory.role == 'harvester') {
            roleHarvester.run(creep);
        }
        if(creep.memory.role == 'upgrader') {
            roleUpgrader.run(creep);
        }
    }
}

 

/main

spawns new creeps if below threshold

var roleHarvester = require('role.harvester');
var roleUpgrader = require('role.upgrader');

module.exports.loop = function () {

    var harvesters = _.filter(Game.creeps, (creep) => creep.memory.role == 'harvester');
    console.log('Harvesters: ' + harvesters.length);

    if(harvesters.length < 2) {
        var newName = 'Harvester' + Game.time;
        console.log('Spawning new harvester: ' + newName);
        Game.spawns['Spawn1'].spawnCreep([WORK,CARRY,MOVE], newName, 
            {memory: {role: 'harvester'}});        
    }
    
    if(Game.spawns['Spawn1'].spawning) { 
        var spawningCreep = Game.creeps[Game.spawns['Spawn1'].spawning.name];
        Game.spawns['Spawn1'].room.visual.text(
            '🛠️' + spawningCreep.memory.role,
            Game.spawns['Spawn1'].pos.x + 1, 
            Game.spawns['Spawn1'].pos.y, 
            {align: 'left', opacity: 0.8});
    }

    for(var name in Game.creeps) {
        var creep = Game.creeps[name];
        if(creep.memory.role == 'harvester') {
            roleHarvester.run(creep);
        }
        if(creep.memory.role == 'upgrader') {
            roleUpgrader.run(creep);
        }
    }
}

 

in order to not cause buffer overflows with random names, this clears the data of dead creeps

/main

var roleHarvester = require('role.harvester');
var roleUpgrader = require('role.upgrader');

module.exports.loop = function () {

    for(var name in Memory.creeps) {
        if(!Game.creeps[name]) {
            delete Memory.creeps[name];
            console.log('Clearing non-existing creep memory:', name);
        }
    }

    var harvesters = _.filter(Game.creeps, (creep) => creep.memory.role == 'harvester');
    console.log('Harvesters: ' + harvesters.length);

    if(harvesters.length < 2) {
        var newName = 'Harvester' + Game.time;
        console.log('Spawning new harvester: ' + newName);
        Game.spawns['Spawn1'].spawnCreep([WORK,CARRY,MOVE], newName, 
            {memory: {role: 'harvester'}});
    }
    
    if(Game.spawns['Spawn1'].spawning) { 
        var spawningCreep = Game.creeps[Game.spawns['Spawn1'].spawning.name];
        Game.spawns['Spawn1'].room.visual.text(
            '🛠️' + spawningCreep.memory.role,
            Game.spawns['Spawn1'].pos.x + 1, 
            Game.spawns['Spawn1'].pos.y, 
            {align: 'left', opacity: 0.8});
    }

    for(var name in Game.creeps) {
        var creep = Game.creeps[name];
        if(creep.memory.role == 'harvester') {
            roleHarvester.run(creep);
        }
        if(creep.memory.role == 'upgrader') {
            roleUpgrader.run(creep);
        }
    }
