快速入门 ​

安装 ​

bash
npm install @lsde/dialog-engine
bash
dotnet add package LsdeDialogEngine

# JSON loader — choose ONE based on your platform:
dotnet add package LsdeDialogEngine.Newtonsoft        # Unity
dotnet add package LsdeDialogEngine.SystemTextJson    # .NET 5+ / Godot .NET
bash
# Add as a git submodule
git submodule add https://github.com/jonlepage/LS-Dialog-Editor-Engine.git deps/lsde

# CMakeLists.txt
add_subdirectory(deps/lsde/lsde-cpp)
target_link_libraries(your_target PRIVATE lsde)
bash
# Copy the headers and source into your project
# e.g. Source/YourModule/ThirdParty/lsde/

cp -r lsde-cpp/include/lsde  YourProject/Source/YourModule/ThirdParty/lsde/include
cp -r lsde-cpp/src/*          YourProject/Source/YourModule/ThirdParty/lsde/src

# In your module's .Build.cs, add:
# PublicIncludePaths.Add(Path.Combine(ModuleDirectory, "ThirdParty/lsde/include"));
# Add the .cpp files from ThirdParty/lsde/src/ to your module
bash
# Clone the repository
git clone https://github.com/jonlepage/LS-Dialog-Editor-Engine.git

# Copy the addon into the Godot project
mkdir -p addons
cp -r LS-Dialog-Editor-Engine/lsde-gdscript/addons/lsde addons/lsde
rm -rf LS-Dialog-Editor-Engine

基本用法 ​

engine 是一个图遍历机器 — 它将 block 分发给已注册的 handler,由 handler 赋予其意义。没有 handler 的话,engine 不会产生任何输出。

格式无关

engine 接收 BlueprintExport 对象,而非文件。您可以使用平台适配的解析器从 JSON、XML 或 YAML 加载蓝图。请参阅解析与导入。

ts
import { DialogueEngine } from '@lsde/dialog-engine';
import blueprintJson from './blueprints.json';

const engine = new DialogueEngine();
engine.init({ data: blueprintJson });

// Unified condition resolver — evaluates game-state conditions for both
// choice visibility and condition block pre-evaluation.
engine.onResolveCondition((cond) => game.evaluateCondition(cond));

// 3 required handlers — bridge between the engine and your game
// (onCondition is optional when onResolveCondition is installed)
engine.onDialog(({ scene, block, context, next }) => {
  game
    .createDialogAuto(block, context)
    .catch(() => scene.cancel())
    .finally(() => next());
});

engine.onChoice(({ scene, block, context, next }) => {
  game
    .createChoiceAuto(block, context)
    .catch(() => scene.cancel())
    .finally(() => next());
});

engine.onAction(({ block, context, next }) => {
  game
    .executeActions(block.actions)
    .catch((err) => context.reject(err))
    .finally(() => next());
});

// Start a scene anywhere in your game code
function myGameScript(sceneId: string) {
  const scene = engine.scene(sceneId);
  scene.start();
}
csharp
using LsdeDialogEngine;
using LsdeDialogEngine.Json; // LsdeDialogEngine.SystemTextJson package
// Unity: use LsdeDialogEngine.Newtonsoft instead

var blueprint = LsdeJson.Parse(File.ReadAllText("blueprints.json"));
var engine = new DialogueEngine();
engine.Init(new InitOptions { Data = blueprint });

// Unified condition resolver — evaluates game-state conditions for both
// choice visibility and condition block pre-evaluation.
engine.OnResolveCondition(cond => Game.EvaluateCondition(cond));

// 3 required handlers — bridge between the engine and your game
engine.OnDialog(args => {
    var (scene, block, context, next) = args;
    Game.ShowDialog(block, context, onComplete: next);
});

engine.OnChoice(args => {
    var (scene, block, context, next) = args;
    Game.ShowChoices(block, context, onSelected: next);
});

engine.OnAction(args => {
    var (scene, block, context, next) = args;
    Game.ExecuteActions(block.Actions);
    context.Resolve();
    next();
});

// Start a scene anywhere in your game code
void MyGameScript(string sceneId) {
    var scene = engine.Scene(sceneId);
    scene.Start();
}
cpp
#include <lsde/engine.h>

using namespace lsde;

DialogueEngine engine;
engine.init({blueprint});

// Unified condition resolver — evaluates game-state conditions for both
// choice visibility and condition block pre-evaluation.
engine.onResolveCondition([](const ConditionTest& cond) {
    return game->evaluateCondition(cond);
});

// 3 required handlers — bridge between the engine and your game
engine.onDialog([](auto* scene, auto* block, auto* ctx, auto next) -> CleanupFn {
    game->showDialog(block, ctx, [next]() { next(); });
    return {};
});

engine.onChoice([](auto* scene, auto* block, auto* ctx, auto next) -> CleanupFn {
    game->showOptions(block, ctx, [next]() { next(); });
    return {};
});

engine.onAction([](auto*, auto* block, auto* ctx, auto next) -> CleanupFn {
    game->executeActions(block->actions);
    ctx->resolve();
    next();
    return {};
});

// Start a scene anywhere in your game code
auto scene = engine.scene(sceneId);
scene->start();
gdscript
var engine = LsdeDialogueEngine.new()
engine.init({"data": blueprint})

# Unified condition resolver — evaluates game-state conditions for both
# choice visibility and condition block pre-evaluation.
engine.on_resolve_condition(func(cond):
    return game.evaluate_condition(cond)
)

# 3 required handlers — bridge between the engine and your game
engine.on_dialog(func(args):
    await game.show_dialog(args["block"], args["context"])
    args["next"].call()
)

engine.on_choice(func(args):
    await game.show_options(args["block"], args["context"])
    args["next"].call()
)

engine.on_action(func(args):
    game.execute_actions(args["block"].actions)
    args["context"].resolve()
    args["next"].call()
)

# Start a scene anywhere in your game code
func my_game_script(scene_id: String):
    var scene = engine.scene(scene_id)
    scene.start()

Blueprint 验证 ​

engine.init() 返回包含错误、警告和统计信息的诊断报告。check 选项可与宿主应用程序的功能进行交叉验证:

ts
engine.init({
  data,
  check: {
    functions: ['set_flag', 'play_sound'],          // function ids your game implements
    dictionaries: { items: ['sword', 'shield'] },   // dictionary ids and their entry keys
    cards: ['Alice', 'Bob'],                        // card NAMES, never the editor id
  },
});
csharp
engine.Init(new InitOptions {
    Data = blueprint,
    Check = new CheckOptions {
        Functions = new() { "set_flag", "play_sound" },
        Dictionaries = new() { ["items"] = new() { "sword", "shield" } },
        Cards = new() { "Alice", "Bob" },
    },
});
cpp
lsde::CheckOptions check;
check.functions = {"set_flag", "play_sound"};
check.dictionaries = {{"items", {"sword", "shield"}}};
check.cards = {"Alice", "Bob"};

engine.init({blueprint, check});
gdscript
engine.init({
    "data": blueprint,
    "check": {
        "functions": ["set_flag", "play_sound"],
        "dictionaries": {"items": ["sword", "shield"]},
        "cards": ["Alice", "Bob"],
    },
})

二十五种诊断 ​

错误 —— payload 被拒绝,什么都不会播放。 errors 非空,engine.scene() 也无从交付。

代码发生了什么
MISSING_DATA没有向 init() 传入 data
MISMATCHED_EXPORTS合并了来自不同导出的多个文件 —— project 或 exportedAt 不一致。请一次只传一个导出的文件
WRONG_NAMING_CONVENTION以 snake_case 或 PascalCase 导出;engine 读取的是 camelCase。项目设置 › 导出器 › 命名约定
INVALID_FORMATformat 不是 lsde-blueprints。C# 和 C++ 对上一种情况也报告这个:它们校验的是已反序列化的类型化对象,原始键名早已丢失
UNSUPPORTED_FORMAT_VERSIONversion 不是 1。仍在 LSDE 1.6 的项目属于 engine 0.3.x —— 没有双读取器
NO_SCENESpayload 里没有任何 scene
DUPLICATE_SCENE两个 scene 共用了 path 或稳定 id
MISSING_SCENE_PATH某个 scene 没有 path
DUPLICATE_BLOCK_ID同一 scene 里两个 block 共用 id。跨 scene 则合法且正常 —— 一个 block 是 (scene, id)
INVALID_START_BLOCKscene 指定的起始 block 并不属于它
BROKEN_LINK有连线指向 scene 中不存在的 block。遍历将无处可去

警告 —— 能播放,但有东西会静默失效。 请阅读它们,没有一条是噪音。

代码你会失去什么
NO_START_BLOCKscene 没有起始 block,start() 无处开始
UNKNOWN_WAIT_BLOCK某个 waitForBlocks id 不是本 scene 的 block,于是那条轨道永久停留。检查无法更进一步:一个确实存在的 id 也可能永远不会被播放
EMPTY_FUNCTION某个 action 有一个未选择函数的调用。游戏收到的是一个无法执行的调用
UNDECLARED_FUNCTION某个 action 调用了导出未声明的函数 —— 例如项目里残留的 v1 id。以前它会静默加载,然后在游戏中失败
UNDECLARED_ARGUMENT某个调用传入了函数未声明的参数
UNDECLARED_DICTIONARY_KEY某个 dictionaryKey 参数不是其参数所指字典中的条目
UNDECLARED_DICTIONARY某个 condition 测试了导出未声明的字典
UNDECLARED_ENTRY某个 condition 测试了字典中未声明的条目
UNKNOWN_CHOICE_BLOCK对保留字典 choice 的测试指向了一个不是本 scene 中 CHOICE 的 block
UNKNOWN_CHOICE_OPTION对保留字典 choice 的测试指向了该 CHOICE 没有的选项
UNKNOWN_FUNCTION某个 action 调用了 check.functions 未列出的函数 id
UNKNOWN_DICTIONARY某个 condition 测试了 check.dictionaries 未列出的字典 id
UNKNOWN_DICTIONARY_ENTRY字典已知,条目键未知
UNKNOWN_CARD某个 block 引用了 check.cards 未列出的角色卡名称

最后四条只在你传入 check 时出现 —— 不传,engine 就没有可比对的东西。 上面那八条始终生效:它们把 block 使用的东西与导出自身声明的东西作比较,因此不需要 check。

在 scene 中发现的诊断带有 sceneId(稳定 id sc_…,即 handle.getSceneId() 返回的值)和 scenePath, 指向某个 block 时还带有 blockId。
