如何使用插件

Runtime AI Chatbot Integrator通过简单的工作流程简化了AI聊天机器人集成到您的Unreal Engine项目中：

1. 注册您的API提供者令牌
2. 配置聊天设置
3. 发送聊天请求（流式或非流式）

注册提供者令牌

在发送聊天请求之前，使用RegisterProviderToken函数注册您的API提供者令牌。

Blueprint

C++

// Register an OpenAI provider token
UAIChatbotCredentialsManager::RegisterProviderToken(
    EAIChatbotIntegratorOrgs::OpenAI, 
    TEXT("sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")
);

聊天请求类型

该插件为每个提供商支持两种聊天请求模式：

非流式聊天请求

在一次调用中检索完整响应。

OpenAI

Blueprint

C++

// Example of sending a non-streaming chat request to OpenAI
FChatbotIntegrator_OpenAISettings Settings;
Settings.Messages.Add(FChatbotIntegrator_OpenAIMessage(
    EChatbotIntegrator_OpenAIRole::SYSTEM, 
    TEXT("You are a helpful assistant.")
));
Settings.Messages.Add(FChatbotIntegrator_OpenAIMessage(
    EChatbotIntegrator_OpenAIRole::USER, 
    TEXT("What is the capital of France?")
));

UAIChatbotIntegratorOpenAI::SendChatRequestNative(
    Settings, 
    FOnOpenAIChatCompletionResponseNative::CreateWeakLambda(
        this, 
        [this](const FString& Response, const FChatbotIntegratorErrorStatus& ErrorStatus)
        {
            UE_LOG(LogTemp, Log, TEXT("Chat completion response: %s, Error: %d: %s"), 
                *Response, ErrorStatus.bIsError, *ErrorStatus.ErrorMessage);
        }
    )
);

DeepSeek

Blueprint

C++

// Example of sending a non-streaming chat request to DeepSeek
FChatbotIntegrator_DeepSeekSettings Settings;
Settings.Messages.Add(FChatbotIntegrator_DeepSeekMessage(
    EChatbotIntegrator_DeepSeekRole::SYSTEM, 
    TEXT("You are a helpful assistant.")
));
Settings.Messages.Add(FChatbotIntegrator_DeepSeekMessage(

        this, 
        [this](const FString& Reasoning, const FString& Content, const FChatbotIntegratorErrorStatus& ErrorStatus)
        {
            UE_LOG(LogTemp, Log, TEXT("Chat completion reasoning: %s, Content: %s, Error: %d: %s"), 
                *Reasoning, *Content, ErrorStatus.bIsError, *ErrorStatus.ErrorMessage);
        }
    )
);

Claude

Blueprint

C++

// Example of sending a non-streaming chat request to Claude
FChatbotIntegrator_ClaudeSettings Settings;
Settings.Messages.Add(FChatbotIntegrator_ClaudeMessage(
    EChatbotIntegrator_ClaudeRole::SYSTEM, 
    TEXT("You are a helpful assistant.")
));
Settings.Messages.Add(FChatbotIntegrator_ClaudeMessage(
    EChatbotIntegrator_ClaudeRole::USER, 
    TEXT("What is the capital of France?")
));

UAIChatbotIntegratorClaudeStream::SendStreamingChatRequestNative(
    Settings, 
    FOnClaudeChatCompletionStreamNative::CreateWeakLambda(
        this, 
        [this](const FString& Response, bool IsFinalChunk, const FChatbotIntegratorErrorStatus& ErrorStatus)
        {
            UE_LOG(LogTemp, Log, TEXT("Streaming chat completion response: %s, IsFinalChunk: %d, Error: %d: %s"), 
                *Response, IsFinalChunk, ErrorStatus.bIsError, *ErrorStatus.ErrorMessage);
        }
    )
);

流式聊天请求

实时接收响应块，实现更动态的交互。

OpenAI

Blueprint

C++

// Example of sending a streaming chat request to OpenAI
FChatbotIntegrator_OpenAISettings Settings;
Settings.Messages.Add(FChatbotIntegrator_OpenAIMessage(
    EChatbotIntegrator_OpenAIRole::SYSTEM, 
    TEXT("You are a helpful assistant.")
));
Settings.Messages.Add(FChatbotIntegrator_OpenAIMessage(
    EChatbotIntegrator_OpenAIRole::USER, 
    TEXT("What is the capital of France?")
));

UAIChatbotIntegratorOpenAIStream::SendStreamingChatRequestNative(
    Settings, 
    FOnOpenAIChatCompletionStreamNative::CreateWeakLambda(
        this, 
        [this](const FString& Response, bool IsFinalChunk, const FChatbotIntegratorErrorStatus& ErrorStatus)
        {
            UE_LOG(LogTemp, Log, TEXT("Streaming chat completion response: %s, IsFinalChunk: %d, Error: %d: %s"), 
                *Response, IsFinalChunk, ErrorStatus.bIsError, *ErrorStatus.ErrorMessage);
        }
    )
);

DeepSeek

Blueprint

C++

// Example of sending a streaming chat request to DeepSeek
FChatbotIntegrator_DeepSeekSettings Settings;
Settings.Messages.Add(FChatbotIntegrator_DeepSeekMessage(
    EChatbotIntegrator_DeepSeekRole::SYSTEM, 
    TEXT("You are a helpful assistant.")
));
Settings.Messages.Add(FChatbotIntegrator_DeepSeekMessage(
    EChatbotIntegrator_DeepSeekRole::USER, 
    TEXT("What is the capital of France?")
));

UAIChatbotIntegratorDeepSeekStream::SendStreamingChatRequestNative(
    Settings, 
    FOnDeepSeekChatCompletionStreamNative::CreateWeakLambda(
        this, 
        [this](const FString& ReasoningChunk, const FString& ContentChunk, 
               bool IsReasoningFinalChunk, bool IsContentFinalChunk, 
               const FChatbotIntegratorErrorStatus& ErrorStatus)
        {
            UE_LOG(LogTemp, Log, TEXT("Streaming chat completion reasoning chunk: %s, Content chunk: %s, IsReasoningFinalChunk: %d, IsContentFinalChunk: %d, Error: %d: %s"), 
                *ReasoningChunk, *ContentChunk, IsReasoningFinalChunk, IsContentFinalChunk, 
                ErrorStatus.bIsError, *ErrorStatus.ErrorMessage);
        }
    )
);

Claude

Blueprint

C++

// Example of sending a streaming chat request to Claude
FChatbotIntegrator_ClaudeSettings Settings;
Settings.Messages.Add(FChatbotIntegrator_ClaudeMessage(
    EChatbotIntegrator_ClaudeRole::SYSTEM, 
    TEXT("You are a helpful assistant.")
));
Settings.Messages.Add(FChatbotIntegrator_ClaudeMessage(
    EChatbotIntegrator_ClaudeRole::USER, 
    TEXT("What is the capital of France?")
));

UAIChatbotIntegratorClaudeStream::SendStreamingChatRequestNative(
    Settings, 
    FOnClaudeChatCompletionStreamNative::CreateWeakLambda(
        this, 
        [this](const FString& Response, bool IsFinalChunk, const FChatbotIntegratorErrorStatus& ErrorStatus)
        {
            UE_LOG(LogTemp, Log, TEXT("Streaming chat completion response: %s, IsFinalChunk: %d, Error: %d: %s"), 
                *Response, IsFinalChunk, ErrorStatus.bIsError, *ErrorStatus.ErrorMessage);
        }
    )
);

错误处理

在发送聊天请求时，通过检查回调中的 ErrorStatus 来处理潜在错误是至关重要的。ErrorStatus 提供了在请求过程中可能出现的任何问题的信息。

Blueprint

C++

// Example of error handling in a chat request
UAIChatbotIntegratorOpenAI::SendChatRequestNative(
    Settings, 
    FOnOpenAIChatCompletionResponseNative::CreateWeakLambda(
        this, 
        [this](const FString& Response, const FChatbotIntegratorErrorStatus& ErrorStatus)
        {
            if (ErrorStatus.bIsError)
            {
                // Handle the error
                UE_LOG(LogTemp, Error, TEXT("Chat request failed: %s"), *ErrorStatus.ErrorMessage);
            }
            else 
            {
                // Process the successful response
                UE_LOG(LogTemp, Log, TEXT("Received response: %s"), *Response);
            }
        }
    )
);

取消请求

该插件允许在流式和非流式聊天请求进行时取消它们。当你想中断一个长时间运行的请求或动态改变对话流程时，这可能会很有用。

Blueprint

C++

// Example of cancelling OpenAI chat request
UAIChatbotIntegratorOpenAI* Request = UAIChatbotIntegratorOpenAI::SendChatRequestNative(
    Settings, 
    ResponseCallback
);

// Cancel the request at any time
Request->Cancel();

// You can also cancel requests for other providers similarly
// UAIChatbotIntegratorDeepSeek::Cancel();
// UAIChatbotIntegratorClaudeStream::Cancel();

最佳实践

1. 始终通过检查回调中的ErrorStatus来处理潜在错误
2. 注意 API 的速率限制和费用
3. 对于长篇或互动对话，请使用流模式
4. 考虑取消不再需要的请求，以有效管理资源

排查问题

• 验证您的 API 凭证是否正确
• 检查您的互联网连接
