Core Concepts

核心概念

Scene Tree Architecture
  • Scenes are collections of nodes arranged in a tree hierarchy
  • Every scene has a root node
  • Nodes inherit from parent nodes and can have multiple children
  • Scene instances can be nested and reused
  • The scene tree is traversed from root to leaves
Node Types
2D Nodes:
  • Node2D: Base for all 2D nodes, has position, rotation, scale
  • Sprite2D: Displays 2D textures
  • AnimatedSprite2D: Plays sprite animations
  • CollisionShape2D: Defines collision areas (must be child of physics body)
  • Area2D: Detects overlapping bodies/areas
  • CharacterBody2D: Physics body with built-in movement functions
  • RigidBody2D: Physics body affected by forces
  • StaticBody2D: Immovable physics body
  • TileMap: Grid-based tile system
  • Camera2D: 2D camera with follow and zoom
  • CanvasLayer: UI layer that stays fixed on screen
  • Control: Base for UI elements (Button, Label, Panel, etc.)
3D Nodes:
  • Node3D: Base for all 3D nodes
  • MeshInstance3D: Displays 3D meshes
  • Camera3D: 3D camera
  • DirectionalLight3D, OmniLight3D, SpotLight3D: Lighting
  • CollisionShape3D: 3D collision shapes
  • Area3D, CharacterBody3D, RigidBody3D, StaticBody3D: 3D physics bodies
Common Nodes:
  • Timer: Execute code after a delay
  • AudioStreamPlayer: Play sounds
  • AnimationPlayer: Control complex animations
场景树架构
  • 场景是按树形层次结构排列的节点集合
  • 每个场景都有一个根节点
  • 节点继承自父节点，可拥有多个子节点
  • 场景实例可嵌套并重复使用
  • 场景树从根节点到叶节点进行遍历
节点类型
2D节点:
  • Node2D：所有2D节点的基础，包含位置、旋转、缩放属性
  • Sprite2D：显示2D纹理
  • AnimatedSprite2D：播放精灵动画
  • CollisionShape2D：定义碰撞区域（必须是物理体的子节点）
  • Area2D：检测重叠的物理体/区域
  • CharacterBody2D：内置移动功能的物理体
  • RigidBody2D：受外力影响的物理体
  • StaticBody2D：不可移动的物理体
  • TileMap：基于网格的瓦片系统
  • Camera2D：具备跟随和缩放功能的2D相机
  • CanvasLayer：固定在屏幕上的UI层
  • Control：所有UI元素的基础（如Button、Label、Panel等）
3D节点:
  • Node3D：所有3D节点的基础
  • MeshInstance3D：显示3D网格
  • Camera3D：3D相机
  • DirectionalLight3D, OmniLight3D, SpotLight3D：灯光节点

GDScript Patterns

GDScript编程模式

Node References:
gdscript
undefined
节点引用:
gdscript
undefined

Get child node

获取子节点

@onready var sprite = $Sprite2D @onready var collision = $CollisionShape2D
@onready var sprite = $Sprite2D @onready var collision = $CollisionShape2D

Get node by path

通过路径获取节点

var player = get_node("/root/Main/Player")
var player = get_node("/root/Main/Player")

Find node by type

按类型查找节点

var camera = get_tree().get_first_node_in_group("camera")

**Common Lifecycle Methods:**
```gdscript
func _ready():
    # Called when node enters scene tree
    pass

func _process(delta):
    # Called every frame
    pass

func _physics_process(delta):
    # Called every physics frame (fixed timestep)
    pass
var camera = get_tree().get_first_node_in_group("camera")

**常用生命周期方法:**
```gdscript
func _ready():
    # 节点进入场景树时调用
    pass

func _process(delta):
    # 每帧调用
    pass

func _physics_process(delta):
    # 每个物理帧调用（固定时间步长）
    pass

Common Tasks

常见任务

Creating a Basic 2D Character:
  1. Create scene with CharacterBody2D root
  2. Add Sprite2D child for visuals
  3. Add CollisionShape2D child for physics
  4. Attach script to root node
  5. Implement movement in _physics_process
Setting Up Camera:
  • 2D: Add Camera2D, enable "Current"
  • 3D: Add Camera3D, adjust position and rotation
  • Use smoothing for better feel
Input Handling:
gdscript
func _input(event):
    if event.is_action_pressed("jump"):
        jump()

func _process(delta):
    var direction = Input.get_axis("left", "right")
创建基础2D角色:
  1. 创建以CharacterBody2D为根节点的场景
  2. 添加Sprite2D子节点用于显示
  3. 添加CollisionShape2D子节点用于物理碰撞
  4. 为根节点附加脚本
  5. 在_physics_process中实现移动逻辑
设置相机:
  • 2D：添加Camera2D节点，启用“Current”选项
  • 3D：添加Camera3D节点，调整位置和旋转角度
  • 使用平滑功能提升体验
输入处理:
gdscript
func _input(event):
    if event.is_action_pressed("jump"):
        jump()

func _process(delta):
    var direction = Input.get_axis("left", "right")
