技術準備
在開始編碼之前,我們需要準備開發環境和相關工具。以下是開發 物流大師 所需的技術棧和資源。
1. 技術棧
- 編程語言:Python 3.x(推薦 3.8 或更高版本)。
- 核心庫:
random:生成隨機事件,如交通堵塞或客户訂單。time:控制遊戲節奏和模擬時間流逝。heapq:實現 Dijkstra 算法優化路線。pygame(可選):用於圖形界面和運輸網絡可視化。
- 數據存儲:
- 使用字典和列表管理城市、路線、車輛和訂單。
- 圖結構表示城市網絡,邊權重為距離或時間。
- 用户界面:基於命令行界面(CLI)顯示遊戲狀態和交互,圖形界面作為擴展。
- 依賴安裝:
random、time和heapq是 Python 標準庫,無需額外安裝。pygame(可選):pip install pygame。
2. 開發環境
確保已安裝 Python(可從 python.org 下載)。推薦使用 Visual Studio Code 或 PyCharm 作為開發工具,提供代碼補全和調試支持。本遊戲的核心版本基於 CLI,擴展部分引入圖形界面。項目結構如下:
logistics_game/
├── main.py # 主程序入口
└── game.py # 遊戲邏輯模塊
3. 遊戲目標
玩家將扮演物流公司經理,目標是在 30 個回合(模擬 30 天)內將公司聲譽提升到 100,同時保持資金正值。遊戲採用回合制,每回合代表一天,玩家需要:
- 接受訂單:選擇客户訂單,包含貨物類型、重量和目的地。
- 調度車輛:分配車輛執行訂單,優化路線。
- 管理資源:平衡燃料成本、維護費用和員工工資。
- 應對事件:處理隨機事件,保持運營穩定。
遊戲設計與核心功能
1. 遊戲結構
我們將遊戲分解為多個模塊,使用類和函數封裝功能,確保代碼清晰且易於維護。以下是核心設計:
City類:表示城市,包含名稱和相鄰城市信息。Vehicle類:表示車輛,包含類型、容量、速度、燃料消耗等。Order類:表示客户訂單,包含貨物、重量、目的地和截止日期。LogisticsGame類:管理遊戲狀態、運輸網絡、車輛、訂單和主循環。- 算法:
- Dijkstra 算法:計算城市間最短路徑。
- 貪心調度:根據車輛容量和訂單優先級分配任務。
- 數據結構:
- 城市網絡:圖結構,節點為城市,邊為距離。
- 車輛:包含位置、狀態(空閒/運輸中)和任務。
- 訂單:包含貨物信息和收益。
- 遊戲狀態:資金、聲譽、車輛列表、訂單列表。
2. 核心代碼實現
以下是遊戲的完整代碼框架,我們將逐一講解每個模塊的實現細節。
2.1 城市類:City
City 類定義城市及其連接。
# game.py
class City:
def __init__(self, name):
"""初始化城市"""
self.name = name
self.neighbors = {} # {鄰居城市: 距離}
def add_neighbor(self, city, distance):
"""添加鄰居城市和距離"""
self.neighbors[city] = distance
説明:
__init__:初始化城市名稱和鄰居字典。add_neighbor:添加相鄰城市和距離,構建圖結構。
2.2 車輛類:Vehicle
Vehicle 類定義車輛的屬性和行為。
# game.py (續)
class Vehicle:
def __init__(self, name, vtype, capacity, speed, fuel_per_km):

self.speed = speed # 速度(km/h)
self.fuel_per_km = fuel_per_km # 每公里燃料成本
self.location = None # 當前所在城市
self.current_order = None # 當前運輸的訂單
self.maintenance_cost = 100 if vtype == "Van" else 200 # 每日維護費用

elif self.status == "Moving":
self.status = "Idle"
self.current_order = None
return True # 訂單完成
return False
説明:
__init__:初始化車輛的名稱、類型、容量、速度和燃料成本。assign_order:分配訂單和運輸路徑,切換狀態為“運輸中”。move:沿路徑移動一步,到達終點則完成訂單。
2.3 訂單類:Order
Order 類定義客户訂單。
# game.py (續)
class Order:
def __init__(self, id, weight, destination, revenue, deadline):
"""初始化訂單"""
self.id = id
self.weight = weight # 貨物重量(噸)
self.destination = destination # 目的地城市
self.revenue = revenue # 收益
self.deadline = deadline # 截止天數
説明:

- 初始化:
- 玩家從 10000 資金和 50 聲譽開始,擁有一輛小型貨車。
- 每回合行動:
- 顯示狀態:查看資金、聲譽、車輛和訂單。
- 購買車輛:選擇小型貨車(5000)或大型卡車(10000)。
- 接受訂單:選擇訂單並分配空閒車輛,計算最短路徑。

- 結束天數,支付維護費用 300,資金為負,遊戲失敗。
遊戲機制詳解
1. 運輸網絡
- 城市:5 個城市(A-E),雙向連接,距離 100-200 km。
- 路徑規劃:Dijkstra 算法計算最短路徑,優化燃料成本。
2. 車輛管理
- 小型貨車:容量 2 噸,速度 60 km/h,燃料 0.5/公里,維護 100/天。
- 大型卡車:容量 5 噸,速度 50 km/h,燃料 1.0/公里,維護 200/天。
- 調度:空閒且容量足夠的車輛可接受訂單。
3. 訂單管理
- 生成:80% 機率生成訂單,重量 1-5 噸,收益 100/噸,截止 3-7 天。
- 完成:車輛到達目的地,獲得收益和聲譽。
- 超時:訂單過期,聲譽 -2。
4. 財務與聲譽
- 收入:完成訂單獲得收益(100/噸)。
- 支出:燃料(距離 × 燃料/公里)、維護費用、車輛購買。
- 聲譽:完成訂單 +2,超時 -2,資金不足 -5。
5. 隨機事件
- 交通堵塞:運輸中車輛延誤一天。
- 車輛故障:額外維修費用(維護費 × 2),未修聲譽 -3。
遊戲擴展與優化
當前版本是一個功能完整的物流遊戲原型,我們可以通過以下方式增強遊戲性、技術實現和深度。
1. 遊戲性增強
- 訂單優先級:引入緊急訂單,收益更高但時間緊。
- 車輛升級:提升容量或速度,降低燃料消耗。
- 員工管理:僱傭司機,影響效率和成本。
- 動態網絡:城市間距離或交通狀況隨時間變化。
示例代碼:緊急訂單
class Order:
def __init__(self, id, weight, destination, revenue, deadline, priority="normal"):
self.id = id
self.weight = weight
self.destination = destination
self.revenue = revenue
self.deadline = deadline
self.priority = priority # normal, urgent
class LogisticsGame:
# ... 其他方法保持不變 ...
def generate_orders(self):
if random.random() < 0.8:
order_id = len(self.orders) + 1
weight = random.randint(1, 5)
destination = random.choice(list(self.cities.values()))
priority = "urgent" if random.random() < 0.3 else "normal"
revenue = weight * (150 if priority == "urgent" else 100)
deadline = random.randint(1, 3) if priority == "urgent" else random.randint(3, 7)
self.orders.append(Order(order_id, weight, destination, revenue, deadline, priority))
print(f"新訂單 ID {order_id}: {weight}t to {destination.name}, ${revenue}, 截止 {deadline} 天 ({priority})。")
def end_turn(self):
self.turn += 1
total_maintenance = sum(v.maintenance_cost for v in self.vehicles)
if self.money >= total_maintenance:
self.money -= total_maintenance
print(f"天數結束,支付維護費用 {total_maintenance}。")
else:
print("資金不足,聲譽下降!")
self.reputation -= 5
for order in self.orders[:]:
order.deadline -= 1
if order.deadline <= 0:
penalty = 5 if order.priority == "urgent" else 2
print(f"訂單 ID {order.id} 超時,聲譽 -{penalty}!")
self.reputation -= penalty
self.orders.remove(order)
for vehicle in self.vehicles:
if vehicle.status == "Moving" and vehicle.move():
revenue = vehicle.current_order.revenue
reputation_gain = 3 if vehicle.current_order.priority == "urgent" else 2
self.money += revenue
self.reputation += reputation_gain
print(f"{vehicle.name} 完成訂單,收入 {revenue},聲譽 +{reputation_gain}")
self.random_event()
實現效果:
- 30% 機率生成緊急訂單,收益 150/噸,截止時間 1-3 天。
- 緊急訂單超時聲譽 -5,完成聲譽 +3,增加策略性。
2. 技術優化
- 圖形界面:使用 Pygame 顯示城市網絡、車輛移動和訂單狀態。
- 存檔功能:保存遊戲狀態到文件。
- 路徑可視化:繪製最短路徑和車輛動畫。
示例代碼:Pygame 界面

pygame.quit()
實現效果:
- 顯示城市網絡(節點為城市,邊為距離),車輛為紅點(空閒)或綠點(運輸中)。
- CLI 交互保留,狀態在屏幕底部顯示。
3. 策略深度
- 多車輛調度:支持同時調度多輛車執行多個訂單。
- 動態成本:燃料價格隨市場波動。
- 客户關係:完成訂單提升客户忠誠度,解鎖高價值訂單。
示例代碼:多車輛調度

實現效果:
- 玩家可同時為多個訂單分配車輛,提升效率。
遊戲策略與玩法分析
1. 玩家策略
- 路線優化:選擇最短路徑減少燃料成本。
- 車輛選擇:根據訂單重量選擇合適車輛。
- 時間管理:優先處理緊急訂單,避免超時。
- 資源平衡:控制車輛數量,平衡維護費用和收入。
2. 平衡性
- 初始資源:10000 資金和 1 輛貨車,適合初期運營。
- 聲譽增長:每次完成訂單 +2(緊急 +3),需 50-75 次完成達標。
- 回合限制:30 天需高效調度。
- 成本與收入:燃料、維護費用與訂單收益需平衡。
3. 重玩價值
- 嘗試不同車輛組合和調度策略。
- 應對隨機事件,調整運營計劃。
- 優化資源管理,實現更高聲譽。
