我用 Python 写了一个AI 玩星际争霸2

首页枪战射击Idle Race Riot更新时间:2024-07-02

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:

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


class SentdeBot(sc2.BotAI):

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

## 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

## 建造水晶

nexuses = self.units(UnitTypeId.NEXUS).ready

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

## 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

建造军队

可以看到,击败了困难人族电脑,但是电脑选择了rush战术,我们写得AI脚本会输掉游戏。显然,这不是最佳方案。“只有AI才能拯救我的胜率”,请看下文。

采集地图数据

这次我们只造一个折跃门,全力通过星门造虚空光辉舰 修改offensive_force_buildings(self)方法的判断

elif len(self.units(GATEWAY)) < 1:

注释或者删除build_offensive_force(self)的建造追猎者的代码

## 造兵

if self.can_afford(UnitTypeId.VOIDRAY) and self.supply_left > 0:
await self.do(sg.train(UnitTypeId.VOIDRAY))

attack(self)中的aggressive_units注释掉Stalker 导入numpy和cv2库

game_data = np.zeros((self.game_info.map_size[1], self.game_info.map_size[0], 3), np.uint8)

建立以地图Heigt为行,Width为列的三维矩阵

for nexus in self.units(NEXUS):
nex_pos = nexus.position
print(nex_pos)
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。

resized = cv2.resize(flipped, dsize=None, fx=2, fy=2)
cv2.imshow('Intel', resized)

## 启动游戏
run_game(maps.get("AcidPlantLE"), [

运行结果如下

采集到了地图位置。

侦察

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


draw_dict = {
UnitTypeId.NEXUS: [15, (0, 255, 0)],
UnitTypeId.PYLON: [3, (20, 235, 0)],
UnitTypeId.PROBE: [1, (55, 200, 0)],
UnitTypeId.ASSIMILATOR: [2, (55, 200, 0)],
UnitTypeId.GATEWAY: [3, (200, 100, 0)],
UnitTypeId.CYBERNETICSCORE: [3, (150, 150, 0)],
UnitTypeId.STARGATE: [5, (255, 0, 0)],
UnitTypeId.ROBOTICSFACILITY: [5, (215, 155, 0)],

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

迭代同上

for unit_type in draw_dict:
for unit in self.units(unit_type).ready:
pos = unit.position
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:
pos = enemy_building.position
if enemy_building.name.lower not in main_base_names:
cv2.circle(game_data, (int(pos[0]), int(pos[1])), 5, (200, 50, 212), -1)
for enemy_building in self.known_enemy_structures:
pos = enemy_building.position
if enemy_building.name.lower in main_base_names:
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:
worker_names = ["probe", "scv", "drone"]
# if that unit is a PROBE, SCV, or DRONE... it's a worker
pos = enemy_unit.position
if enemy_unit.name.lower in worker_names:
cv2.circle(game_data, (int(pos[0]), int(pos[1])), 1, (55, 0, 155), -1)
else:
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:
if len(self.units(ROBOTICSFACILITY)) < 1:
if self.can_afford(ROBOTICSFACILITY) and not self.already_pending(ROBOTICSFACILITY):
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
