Core Principles (All Platforms)

核心原则（全平台通用）

1. The Game Loop

1. Game Loop（游戏循环）

Every game, regardless of platform, follows this pattern:
INPUT  → Read player actions
UPDATE → Process game logic (fixed timestep)
RENDER → Draw the frame (interpolated)
Fixed Timestep Rule:
  • Physics/logic: Fixed rate (e.g., 50Hz)
  • Rendering: As fast as possible
  • Interpolate between states for smooth visuals
无论面向哪个平台，所有游戏都遵循以下模式：
INPUT  → 读取玩家操作
UPDATE → 处理游戏逻辑（固定时间步长）
RENDER → 绘制画面（插值处理）
固定时间步长规则：
  • 物理/逻辑：固定速率（例如50Hz）
  • 渲染：尽可能快
  • 对状态进行插值处理以实现流畅视觉效果

2. Pattern Selection Matrix

2. 模式选择矩阵

PatternUse WhenExample
State Machine3-5 discrete statesPlayer: Idle→Walk→Jump
Object PoolingFrequent spawn/destroyBullets, particles
Observer/EventsCross-system communicationHealth→UI updates
ECSThousands of similar entitiesRTS units, particles
CommandUndo, replay, networkingInput recording
Behavior TreeComplex AI decisionsEnemy AI
Decision Rule: Start with State Machine. Add ECS only when performance demands.
模式适用场景示例
状态机（State Machine）3-5种离散状态玩家：Idle→Walk→Jump
对象池（Object Pooling）需要频繁生成/销毁对象子弹、粒子效果
观察者/事件模式（Observer/Events）跨系统通信生命值变化→UI更新
ECS（实体组件系统）存在大量相似实体RTS单位、粒子效果
命令模式（Command）撤销、回放、网络同步输入记录
行为树（Behavior Tree）复杂AI决策敌人AI
决策规则： 从状态机开始，仅当性能要求较高时再使用ECS。

3. Input Abstraction

3. 输入抽象

Abstract input into ACTIONS, not raw keys:
"jump"  → Space, Gamepad A, Touch tap
"move"  → WASD, Left stick, Virtual joystick
Why: Enables multi-platform, rebindable controls.
将输入抽象为动作，而非原始按键：
"jump"  → 空格键、游戏手柄A键、触摸点击
"move"  → WASD键、左摇杆、虚拟摇杆
优势： 支持多平台、可重新绑定的控制方式。

4. Performance Budget (60 FPS = 16.67ms)

4. 性能预算（60 FPS = 16.67毫秒）

SystemBudget
Input1ms
Physics3ms
AI2ms
Game Logic4ms
Rendering5ms
Buffer1.67ms
Optimization Priority:
  1. Algorithm (O(n²) → O(n log n))
  2. Batching (reduce draw calls)
  3. Pooling (avoid GC spikes)
  4. LOD (detail by distance)
  5. Culling (skip invisible)
系统预算
输入1毫秒
物理3毫秒
AI2毫秒
游戏逻辑4毫秒
渲染5毫秒
缓冲1.67毫秒
优化优先级：
  1. 算法优化（O(n²) → O(n log n)）
  2. 批处理（减少绘制调用）
  3. 对象池（避免GC峰值）
  4. LOD（根据距离调整细节）
  5. 剔除（跳过不可见对象）

5. AI Selection by Complexity

5. 按复杂度选择AI类型

AI TypeComplexityUse When
FSMSimple3-5 states, predictable behavior
Behavior TreeMediumModular, designer-friendly
GOAPHighEmergent, planning-based
Utility AIHighScoring-based decisions
AI类型复杂度适用场景
FSM（有限状态机）简单3-5种状态、可预测行为
行为树中等模块化、便于设计师使用
GOAP（目标导向动作规划）高涌现式、基于规划的行为
效用AI高基于评分的决策

6. Collision Strategy

6. 碰撞检测策略

TypeBest For
AABBRectangles, fast checks
CircleRound objects, cheap
Spatial HashMany similar-sized objects
QuadtreeLarge worlds, varying sizes
类型最佳适用场景
AABB（轴对齐 bounding box）矩形对象、快速检测
圆形碰撞圆形对象、计算成本低
空间哈希大量相似尺寸的对象
四叉树大型世界、对象尺寸不一

Anti-Patterns (Universal)

反模式（通用）

Don'tDo
Update everything every frameUse events, dirty flags
Create objects in hot loopsObject pooling
Cache nothingCache references
Optimize without profilingProfile first
Mix input with logicAbstract input layer
不要做应该做
每帧更新所有对象使用事件、脏标记
在热循环中创建对象使用对象池
不做任何缓存缓存引用
未做性能分析就优化先做性能分析
将输入与逻辑混合抽象输入层
