简化元附加信息的使用 about iogame HOT 1 CLOSED

// 自定义一个元信息类，实现 Attachment 元附加信息接口
@ProtobufClass
@FieldDefaults(level = AccessLevel.PUBLIC)
public class MyAttachment implements Attachment {
    @Getter
    long userId;
    String nickname;
}

@ActionController(1)
public class DemoAction {
    @ActionMethod(1)
    public void attachment(FlowContext flowContext) {
    	// 创建自定义的元附加信息对象
        MyAttachment myAttachment = new MyAttachment();
        myAttachment.userId = flowContext.getUserId();
        myAttachment.nickname = "英雄无敌3";
    	
        // 设置元信息 ----- 关键代码
        ExternalCommunicationKit.setAttachment(myAttachment);
    }

    @ActionMethod(2)
    public MyAttachment printAttachment(FlowContext flowContext) {
    	// 得到元信息，这个是在上面的方法中设置的元信息对象
        var attachment = flowContext.getAttachment(MyAttachment.class);

        return attachment;
    }
}
