    void set_tree(tree<type> *a,int deep,sf::String Root_name="1"){
        seq=a;
        add_data(seq,deep,Root_name);
    }

    void add_data(tree<type> *a, int counter=0, sf::String nama="1"){
        if(counter == 3);

    }
    int Load_now(sf::String seq='1'){
        path = "Sequence/" + seq +".png";
        texture.loadFromFile(path);
        BG_img.setTexture(texture);

        ifstream ff;
        string data, option1, option2, option3;
        string s_path =  "Sequence/" + seq + ".txt";
        ff.open(s_path, ios::in);
        getline(ff,data);
        getline(ff,option1);
        if(!ff.eof()) getline(ff,option2);
        if(!ff.eof()) getline(ff,option3);
        ff.close();


        //setting text position
        text.setPosition(0,0);
        sfoption1.setPosition(0,1);
        sfoption2.setPosition(0,2);
        sfoption3.setPosition(0,3);

        //passing text
        text.setString(data);
        sfoption1.setString(option1);
        if(option1 == "Main menu") return 0;
        else return 1;
        if(option2 != "") sfoption2.setString(option2);
        if(option3 != "") sfoption3.setString(option3);


    }

    int next(int inp){
        return load_now(seq->get_data(inp));
    }
    void draw(sf::RenderWindow &window){
        window.draw(BG_img);
        //draW TO DISPLAY text
        window.draw(text);
        window.draw(sfoption1);
        if(sfoption2 != NULL) window.draw(sfoption2);
        if(sfoption3 != NULL) window.draw(sfoption3);
    }
    void chhose(int x){
    }
};

所以我有学校项目，我在c ++中创建它作为头文件。但是当我编译这个错误时出现了 “错误C3861：'load_now'：未找到标识符第92行”。我不明白为什么以及如何解决它。

Answer 1

什么是seq->get_data(inp)返回？我认为编译器不确定seq->get_data(inp)的数据类型。

而Load_now不是load_now

Answer 2

您的代码中存在轻微问题。你有Load_now。所以，

return load_now(seq->get_data(inp));

替换为

return Load_now(seq->get_data(inp));

在类c ++中找不到标识符
