A little guide for the game Screeps, on how to mine minerals and make your first credits by selling some to a market order.

Screeps is a real-time strategy Javascript-programming game.

Code used in the video:

-------------------- Extractor --------------------

var roleExtractor = {

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

if (creep.memory.extracting && creep.carryCapacity == _.sum(creep.carry)) {
creep.memory.extracting = false;
}
if (!creep.memory.extracting && 0 == _.sum(creep.carry)) {
creep.memory.extracting = true;
if (creep.ticksToLive < 200) {
creep.suicide();
}
}

if (creep.memory.extracting) {
var target;

if (creep.memory.depositId) {
target = Game.getObjectById(creep.memory.depositId);
} else {
var targets = creep.room.find(FIND_MINERALS);
target = targets[0];
creep.memory.depositId = target.id;
creep.memory.mineralType = target.mineralType;
}
if (creep.harvest(target) == ERR_NOT_IN_RANGE) {
creep.moveTo(target);
}
} else {
if (creep.room.terminal) {
if (creep.transfer(creep.room.terminal, creep.memory.mineralType) == ERR_NOT_IN_RANGE) {
creep.moveTo(creep.room.terminal);
}
} else if (creep.room.storage) {
if (creep.transfer(creep.room.storage, creep.memory.mineralType) == ERR_NOT_IN_RANGE) {
creep.moveTo(creep.room.storage);
}
}
}
}
};

module.exports = roleExtractor;

-------------------- Sell to market order --------------------

// Terminal trade execution
if (spawn.room.terminal && (Game.time % 10 == 0)) {
if (spawn.room.terminal.store[RESOURCE_ENERGY] >= 2000 && spawn.room.terminal.store[RESOURCE_HYDROGEN] >= 2000) {
var orders = Game.market.getAllOrders(order => order.resourceType == RESOURCE_HYDROGEN &&
order.type == ORDER_BUY &&
Game.market.calcTransactionCost(200, spawn.room.name, order.roomName) < 400);
console.log('Hydrogen buy orders found: ' + orders.length);
orders.sort(function(a,b){return b.price - a.price;});
console.log('Best price: ' + orders[0].price);
if (orders[0].price > 0.7) {
var result = Game.market.deal(orders[0].id, 200, spawn.room.name);
if (result == 0) {
console.log('Order completed successfully');
}
}
}
}

-------------------- View order on console --------------------

JSON.stringify(Game.market.getAllOrders(order => order.resourceType == RESOURCE_GHODIUM && order.type == ORDER_SELL && Game.market.calcTransactionCost(200, 'W12N64', order.roomName) < 500));
