Godot .tscn 场景文件格式规范
用途：让 AI 能够直接读写 Godot 场景文件
版本：v1.0 · 2026-04-24
适用引擎：Godot 4.x
核心原则
Godot 场景文件是纯文本，AI 可以直接通过 write_to_file 和 replace_in_file 操作，无需任何中间层。
一、文件结构总览
[gd_scene load_steps=N format=3 uid="uid://xxx"] ← 头部（必需）
[ext_resource type="Type" path="res://..." id="ID"] ← 外部资源引用（可选）
[ext_resource ...]
[sub_resource type="Type" id="ID"] ← 内嵌资源定义（可选）
property = value
[sub_resource ...]
[node name="Name" type="Type"] ← 根节点（必需）
property = value
[node name="Child" type="Type" parent="."] ← 子节点
property = value
[connection signal="sig" from="Node" to="Target" method="func"] ← 信号连接（可选）
二、头部声明
2.1 基本格式
[gd_scene load_steps=4 format=3]
| 字段 | 说明 |
|---|
load_steps | 资源加载步数 = ext_resource 数 + sub_resource 数 + 1（场景本身） |
format | 固定为 3（Godot 4.x） |
uid | 可选，Godot 自动生成的唯一 ID，创建时可省略 |
2.2 计算 load_steps
load_steps = len(ext_resources) + len(sub_resources) + 1
示例：2 个外部资源 + 3 个内嵌资源 → load_steps=6
三、外部资源引用 (ext_resource)
3.1 格式
[ext_resource type="Type" path="res://path/to/file" id="ID"]
3.2 常见类型
| type | 文件类型 | 示例 |
|---|
Script | GDScript | path="res://scripts/player.gd" |
PackedScene | 场景 | path="res://scenes/enemy.tscn" |
Material | 材质资源 | path="res://materials/floor.tres" |
Texture2D | 2D 纹理 | path="res://textures/icon.png" |
AudioStream | 音频 | path="res://audio/shoot.wav" |
Shader | 着色器 | path="res://shaders/outline.gdshader" |
3.3 ID 命名规范
AI 生成时使用有意义的 ID：
[ext_resource type="Script" path="res://scripts/player.gd" id="1_player_script"]
[ext_resource type="Material" path="res://resources/floor_mat.tres" id="2_floor_mat"]
[ext_resource type="PackedScene" path="res://scenes/bullet.tscn" id="3_bullet_scene"]
四、内嵌资源定义 (sub_resource)
4.1 格式
[sub_resource type="Type" id="ID"]
property1 = value1
property2 = value2
4.2 常用碰撞形状
# 胶囊体（角色常用）
[sub_resource type="CapsuleShape3D" id="CapsuleShape3D_player"]
radius = 0.35
height = 1.8
# 球体
[sub_resource type="SphereShape3D" id="SphereShape3D_001"]
radius = 0.5
# 盒子
[sub_resource type="BoxShape3D" id="BoxShape3D_floor"]
size = Vector3(10, 0.2, 10)
# 圆柱体
[sub_resource type="CylinderShape3D" id="CylinderShape3D_001"]
height = 2.0
radius = 0.5
# 2D 形状
[sub_resource type="RectangleShape2D" id="RectangleShape2D_001"]
size = Vector2(32, 32)
[sub_resource type="CircleShape2D" id="CircleShape2D_001"]
radius = 16.0
4.3 常用网格
# 盒子网格
[sub_resource type="BoxMesh" id="BoxMesh_001"]
size = Vector3(1, 1, 1)
# 球体网格
[sub_resource type="SphereMesh" id="SphereMesh_001"]
radius = 0.5
height = 1.0
# 胶囊网格
[sub_resource type="CapsuleMesh" id="CapsuleMesh_001"]
radius = 0.5
height = 2.0
# 圆柱网格
[sub_resource type="CylinderMesh" id="CylinderMesh_001"]
top_radius = 0.5
bottom_radius = 0.5
height = 2.0
# 平面网格
[sub_resource type="PlaneMesh" id="PlaneMesh_001"]
size = Vector2(10, 10)
4.4 材质（内嵌）
[sub_resource type="StandardMaterial3D" id="Material_red"]
albedo_color = Color(1, 0, 0, 1)
roughness = 0.8
metallic = 0.2
# 发光材质
[sub_resource type="StandardMaterial3D" id="Material_glow"]
emission_enabled = true
emission = Color(1, 0.8, 0, 1)
emission_energy_multiplier = 2.0
五、节点声明 (node)
5.1 根节点
[node name="Player" type="CharacterBody3D"]
script = ExtResource("1_player_script")
5.2 子节点
[node name="ChildName" type="NodeType" parent="."]
property = value
| parent 值 | 含义 |
|---|
. | 直接子节点（父节点是根） |
ParentName | 指定父节点名 |
Parent/Child | 嵌套路径 |
5.3 引用资源
# 引用外部资源
script = ExtResource("1_player_script")
mesh = ExtResource("2_mesh")
# 引用内嵌资源
shape = SubResource("CapsuleShape3D_player")
mesh = SubResource("BoxMesh_001")
5.4 实例化场景
[node name="Enemy1" parent="Enemies" instance=ExtResource("4_enemy_scene")]
transform = Transform3D(1, 0, 0, 0, 1, 0, 0, 0, 1, 5, 0, -10)
六、Transform 变换
6.1 Transform3D 格式
transform = Transform3D(bx.x, bx.y, bx.z, by.x, by.y, by.z, bz.x, bz.y, bz.z, ox, oy, oz)
| 参数 | 含义 |
|---|
| bx (1-3) | X 轴基向量 |
| by (4-6) | Y 轴基向量 |
| bz (7-9) | Z 轴基向量 |
| o (10-12) | 位置 (origin) |
6.2 常用变换
# 单位变换（默认位置）
transform = Transform3D(1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0)
# 仅位置
transform = Transform3D(1, 0, 0, 0, 1, 0, 0, 0, 1, 5, 2, -10)
# 位置 + 缩放 0.5
transform = Transform3D(0.5, 0, 0, 0, 0.5, 0, 0, 0, 0.5, 5, 2, -10)
# 绕 Y 轴旋转 90°（sin90=1, cos90=0）
transform = Transform3D(0, 0, 1, 0, 1, 0, -1, 0, 0, 0, 0, 0)
6.3 Transform2D 格式
transform = Transform2D(cos, sin, -sin, cos, x, y)
# 单位变换
transform = Transform2D(1, 0, 0, 1, 100, 200)
# 旋转 45° 位于 (100, 200)
transform = Transform2D(0.707, 0.707, -0.707, 0.707, 100, 200)
七、常用属性值格式
7.1 基础类型
# 布尔
visible = true
enabled = false
# 整数
health = 100
# 浮点
speed = 10.5
# 字符串
name = "Player"
7.2 向量
# Vector2
position = Vector2(100, 200)
size = Vector2(32, 32)
# Vector3
position = Vector3(0, 1.5, 0)
target_position = Vector3(0, 0, -100)
# Vector4
custom_data = Vector4(1, 2, 3, 4)
7.3 颜色
# Color(R, G, B, A) 范围 0.0-1.0
light_color = Color(1, 0.85, 0.3, 1)
albedo_color = Color(0.25, 0.25, 0.3, 1)
# 半透明
modulate = Color(1, 1, 1, 0.5)
7.4 数组
# PackedStringArray
config/features = PackedStringArray("4.6", "Forward Plus")
# PackedVector2Array
polygon = PackedVector2Array(0, 0, 100, 0, 100, 100, 0, 100)
# 普通数组
groups = ["enemy", "damageable"]
八、信号连接 (connection)
8.1 格式
[connection signal="signal_name" from="NodePath" to="TargetPath" method="method_name"]
8.2 示例
# 同级节点连接
[connection signal="timeout" from="ShootCooldown" to="." method="_on_shoot_cooldown_timeout"]
# 子节点连接到根
[connection signal="body_entered" from="HitArea" to="." method="_on_hit_area_body_entered"]
# 带 flags
[connection signal="pressed" from="Button" to="." method="_on_button_pressed" flags=1]

十、AI 操作指南
10.1 创建新场景
write_to_file("res://scenes/new_scene.tscn", """
[gd_scene load_steps=1 format=3]
[node name="Root" type="Node3D"]
""")
10.2 修改现有场景
replace_in_file("res://scenes/player.tscn",
old_str='fov = 75.0',
new_str='fov = 90.0'
)
10.3 添加节点
replace_in_file("res://scenes/player.tscn",
old_str='[connection signal=',
new_str='''[node name="NewChild" type="Node3D" parent="."]
transform = Transform3D(1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0)
[connection signal='''
)
10.4 常见错误排查
| 错误 | 原因 | 修复 |
|---|
load_steps 不匹配 | 资源数计算错误 | 重新计算 ext + sub + 1 |
id not found | 引用了不存在的资源 ID | 检查 ExtResource/SubResource ID |
| 场景无法加载 | parent 路径错误 | 检查节点层级关系 |
| 属性无效 | 类型拼写错误 | 查阅 Godot 文档确认属性名 |
