我用 Python 写了一个AI 玩星际争霸2

编程派 • 6 年前 • 896 次点击  

Deepmind 开放了自己的星际争霸机器学习环境，现在只需要安装对应的 pysc2 包，就可以自己写一个星际2 AI啦！本文是Rest探路者分享在博客园的一个相关项目，里面有非常详尽的代码，有兴趣的小伙伴可以参考。

准备

我的环境是python3.6，sc2包0.11.1，机器学习包：pysc2，地图下载链接maps：https://github.com/Blizzard/s2client-proto#downloads。

pysc2是DeepMind开发的星际争霸Ⅱ学习环境。它是封装星际争霸Ⅱ机器学习API，同时也提供Python增强学习环境。以神族为例编写代码，神族建筑科技图如下：

采矿

import sc2
from sc2 import run_game, maps, Race, Difficulty
from sc2.player import Bot, Computer


class SentdeBot(sc2.BotAI):
    async def on_step(self, iteration: int):
        await self.distribute_workers()


run_game(maps.get("AcidPlantLE"), [
    Bot(Race.Protoss, SentdeBot()), Computer(Race.Terran, Difficulty.Easy)
],realtime = True)

注意game_data.py的assert self.id != 0注释掉 pixel_map.py的assert self.bits_per_pixel % 8 == 0, "Unsupported pixel density"注释掉，否则会报错

运行结果如下，农民开始采矿

可以正常采矿

建造农民和水晶塔

import sc2

from sc2.player import Bot, Computer
from sc2.constants import *


class SentdeBot(sc2.BotAI):
    async def on_step(self, iteration: int):
        await self.distribute_workers()
        await self.build_workers()
        await self.build_pylons()

    # 建造农民
    async def build_workers(self):
        # 星灵枢纽(NEXUS)无队列建造，可以提高晶体矿的利用率，不至于占用资源
        for


    
 nexus in self.units(UnitTypeId.NEXUS).ready.noqueue:
            # 是否有50晶体矿
            if self.can_afford(UnitTypeId.PROBE):
                await self.do(nexus.train(UnitTypeId.PROBE))

    ## 建造水晶
    async def build_pylons(self):
        ## 供应人口和现有人口之差小于5且水晶不是正在建造
        if self.supply_left<5 and not self.already_pending(UnitTypeId.PYLON):
            nexuses = self.units(UnitTypeId.NEXUS).ready
            if nexuses.exists:

                    await self.build(UnitTypeId.PYLON,near=nexuses.first)

## 启动游戏
run_game(maps.get("AcidPlantLE"), [
    Bot(Race.Protoss, SentdeBot()), Computer(Race.Terran, Difficulty.Easy)
],realtime = True)

运行结果如下，基地造农民，农民造水晶

收集气体和开矿

代码如下

import sc2

from sc2.player import Bot, Computer
from sc2.constants import *


class SentdeBot(sc2.BotAI):

            if self.can_afford(UnitTypeId.PROBE):
                await self.do(nexus.train(UnitTypeId.PROBE))

    ## 建造水晶
    async def build_pylons(self):
        ## 供应人口和现有人口之差小于5且建筑不是正在建造
        if self.supply_left < 5 and not self.already_pending(UnitTypeId.PYLON):
            nexuses = self.units(UnitTypeId.NEXUS).ready
            if nexuses.exists:

                    await self.build(UnitTypeId.PYLON, near=nexuses.first)

    ## 建造吸收厂
    async def build_assimilators(self):
        for nexus in self.units(UnitTypeId.NEXUS).ready:
            # 在瓦斯泉上建造吸收厂
            vaspenes = self.state.vespene_geyser.closer_than(15.0,nexus)
            for vaspene in vaspenes:
                if not self.can_afford(UnitTypeId.ASSIMILATOR):
                    break
                worker = self.select_build_worker(vaspene.position)



    
                if worker is None:
                    break
                if not self.units(UnitTypeId.ASSIMILATOR).closer_than(1.0,vaspene).exists:
                    await self.do(worker.build(UnitTypeId.ASSIMILATOR,vaspene))

    ## 开矿
    async def expand(self):
        if self.units(UnitTypeId.NEXUS).amount<3 and self.can_afford(UnitTypeId.NEXUS):
            await self.expand_now()

## 启动游戏
run_game(maps.get("AcidPlantLE"), [
    Bot(Race.Protoss, SentdeBot()), Computer(Race.Terran, Difficulty.Easy)
], realtime=False)

run_game的realtime设置成False，可以在加速模式下运行游戏。

运行效果如下：

可以建造吸收厂和开矿

采集地图数据

建立以地图Heigt为行，Width为列的三维矩阵

for nexus in self.units(NEXUS):

            cv2.circle(game_data, (int(nex_pos[0]), int(nex_pos[1])), 10, (0, 255, 0), -1)  # BGR

遍历星灵枢纽，获取下一个位置，画圆，circle(承载圆的img, 圆心, 半径, 颜色, thickness=-1表示填充)，接下来我们要垂直翻转三维矩阵，因为我们建立的矩阵左上角是原点(0,0)，纵坐标向下延申，横坐标向右延申。翻转之后就成了正常的坐标系。

flipped = cv2.flip(game_data, 0)

图像缩放，达到可视化最佳。

在intel(self)里创建一个字典draw_dict，UnitTypeId作为key,半径和颜色是value

            UnitTypeId.VOIDRAY: [3, (255, 100, 0)]
        }

迭代同上

for unit_type in draw_dict:

                cv2.circle(game_data, (int(pos[0]), int(pos[1])), draw_dict[unit_type][0], draw_dict[unit_type][1], -1)

存储三族的主基地名称（星灵枢纽，指挥中心，孵化场），刻画敌方建筑。

# 主基地名称
        main_base_names = ["nexus", "supplydepot", "hatchery"]
        # 记录敌方基地位置
        for enemy_building in self.known_enemy_structures:

                cv2.circle(game_data, (int(pos[0]), int(pos[1])), 15, (0, 0, 255), -1)

刻画敌方单位，如果是农民画得小些，其他单位则画大些。




    
        for enemy_unit in self.known_enemy_units:

            if not enemy_unit.is_structure:

                    cv2.circle(game_data, (int(pos[0]), int(pos[1])), 3, (50, 0, 215), -1)

在offensive_force_buildings(self)方法中添加建造机械台

            if self.units(CYBERNETICSCORE).ready.exists:

                        await self.build(ROBOTICSFACILITY, near=pylon)

创建scout()，训练Observer

async def scout(self):
        if len(self.units(OBSERVER)) > 0:
            scout = self.units(OBSERVER)[0]
            if scout.is_idle:
                enemy_location = self.enemy_start_locations[0]
                move_to = self.random_location_variance(enemy_location)
                print(move_to)
                await self.do(scout.move(move_to))

        else:
            for rf in self.units(ROBOTICSFACILITY).ready.noqueue:
                if self.can_afford(OBSERVER) and self.supply_left > 0:
                    await self.do(rf.train(OBSERVER))

生成随机位置，很简单。意思是横坐标累计递增-0.2和0.2倍的横坐标，限制条件为如果x超过横坐标，那么就是横坐标最大值。

纵坐标同理。

    def random_location_variance(self, enemy_start_location):
        x = enemy_start_location[0]
        y = enemy_start_location[1]

        x += ((random.randrange(-20, 20))/100) * enemy_start_location[0]
        y += ((random.randrange(-20, 20))/100) * enemy_start_location[1]

        if x < 0:
            x = 0
        if y < 0:
            y = 0
        if x > self.game_info.map_size[0]:
            x = self.game_info.map_size[0]
        if y > self.game_info.map_size[1]:
            y = self.game_info.map_size[1]

        go_to = position.Point2(position.Pointlike((x,y)))
        return go_to
