Text advancing or getting to the new line of text

[Daoxin]

So I have been working on a text-based adventure game where it is heavy on text and choices you make. The main problem is that the text I try to set up does appear in the game but does not advance after clicking enter and been struggling with it. Should I make a new class for the text that will be read off from or put it all in this current class I have made. So far I can make only one text appear if the player clicks enter and that is good. That is what I want but want to delete the text after they click enter and a new text appears. I tried to do if statements, when they click, enter and works but that is WAY TOO MANY if to continue the story. Wondering if maybe I just need to make a new class that if you click enter, a new text appears or something. I know it has to update or something to advance the text string but unsure what it could be.

Here is the code I have made so far in different classes:

GamePlay::GamePlay(std::shared_ptr<Context> &context) : context(context),
AdvanceButton(false)
{

}

GamePlay::~GamePlay()
{

}

void GamePlay::Init()
{
    //rectangle shape of the chat box
    chatBox.setSize({1500, 320});
    chatBox.setFillColor(sf::Color::Black);
    chatBox.setOutlineColor(sf::Color::White);
    chatBox.setOutlineThickness(5.f);
    chatBox.setOrigin(chatBox.getGlobalBounds().width/1,
                        chatBox.getGlobalBounds().height/1);
    chatBox.setPosition(context->window->getSize().x/1.1f,
                        context->window->getSize().y/1.01f);

    //Titlle screen name of the game code
    context -> assets ->AddFont(MainFont, "Assets/Asdonuts.ttf");
    text.setFont(context->assets->GetFont(MainFont));

    text.setCharacterSize(50);
    text.setFillColor(sf::Color::White);
    text.setPosition(context->window->getSize().x/5.7f,
                     context->window->getSize().y/2);
}

void GamePlay::ProcessInput()
{
    sf::Event event;
    while(context->window->pollEvent(event))
    {
        if (event.type == sf::Event::Closed)
        {
            context->window->close();
        }

        else if(event.type == sf::Event::KeyPressed)
        {

            switch(event.key.code)
            {
                case sf::Keyboard::Enter:
                {
                    text.setString("Hey There");

                    text.setString("Welcome here");//ignore these two as I was just texting this part out that it could work like this

                    text.setString("Wow");//ignore this one too



                    break;
                }
            }
        }
    }
}

void GamePlay::Update(sf::Time deltaTime)
{

}

void GamePlay::Draw()
{
    context->window->clear(sf::Color::Black);
    context->window->draw(chatBox);
    context->window->draw(text);
    context->window->display();
}

i don't know if I really understand your question... you want to change to a new text everytime the user press Enter? if that's the point, I don't think you need a class for simply holding a text. you could simply have an array of texts. example:

#include <SFML/Graphics.hpp>

int main(){
    sf::RenderWindow window(sf::VideoMode(800, 600), "Text Adventure");

    unsigned int text_counter = 0;
    std::string text_array[] = {"This is the first text",
                                "This is the second one",
                                "And third text",
                                "End"};
    sf::Font font;
    if (!font.loadFromFile("automati.ttf"))
        return 1;
    sf::Text text("", font, 20);

    while (window.isOpen()){
        sf::Event event;
        while (window.pollEvent(event)){
            if (event.type == sf::Event::Closed){
                window.close();
            }
            if (event.type == sf::Event::KeyPressed && event.key.code == sf::Keyboard::Return){
                if (text_counter < (sizeof(text_array)/sizeof(text_array[0]))){
                    text.setString(text_array[text_counter]);
                    text_counter++;
                }
            }

        }
        window.clear();
        window.draw(text);
        window.display();
    }
    return 0;
}

I see what you mean, I might give that a try then and yes that was my question haha sorry about the confusion. I will give the array a try just a bit worried as it is long with choices and having puzzles involved but will see if that will work then. Thank you!

        window.display();
    }
    return 0;
}
 

Strangely that did not work for me, It stays in the first line from the array. Thanks though but I will try using the array as you said for a bit.

[Stauricus]

well that's weird. are you sure you copy/pasted everything when testing it?
the code is fine, and I tested it again... see video attached

just a bit worried as it is long with choices and having puzzles involved

two suggestions then:
1) make an array (or even better, a std::vector) for each 'level' of your game
2) for puzzles and choices, you could use an approach like in old book series "Choose Your Own Adventure", in which any choice you make will take you to a different page. but instead of pages, you just load a different element from your array/vector.

I copied the

unsigned int text_counter = 0;
    std::string text_array[] = {"This is the first text",
                                "This is the second one",
                                "And third text",
                                "End"};
if (event.type == sf::Event::KeyPressed && event.key.code == sf::Keyboard::Return)
        {
            if (text_counter < (sizeof(text_array) / sizeof(text_array[0])))
            {
                text.setString(text_array[text_counter]);
                text_counter++;
            }
        }

Parts into mine and yeah only the first part of the array appears only. I even put the array in the same class function I have for the event to see if that was the issue but was not.

GamePlay::GamePlay(std::shared_ptr<Context> &context) : context(context),
AdvanceButton(false)
{

}

GamePlay::~GamePlay()
{

}

void GamePlay::Init()
{
    //rectangle shape of the chat box
    chatBox.setSize({1500, 320});
    chatBox.setFillColor(sf::Color::Black);
    chatBox.setOutlineColor(sf::Color::White);
    chatBox.setOutlineThickness(5.f);
    chatBox.setOrigin(chatBox.getGlobalBounds().width/1,
                        chatBox.getGlobalBounds().height/1);
    chatBox.setPosition(context->window->getSize().x/1.1f,
                        context->window->getSize().y/1.01f);

    //Titlle screen name of the game code
    context -> assets ->AddFont(MainFont, "Assets/Asdonuts.ttf");
    text.setFont(context->assets->GetFont(MainFont));

    text.setCharacterSize(50);
    text.setFillColor(sf::Color::White);
    text.setPosition(context->window->getSize().x/5.7f,
                     context->window->getSize().y/2);


}

void GamePlay::ProcessInput()
{

    unsigned int text_counter = 0;
    std::string text_array[] = {"This is the first text",
                                "This is the second one",
                                "And third text",
                                "End"};

    sf::Event event;
    while(context->window->pollEvent(event))
    {
        if (event.type == sf::Event::Closed)
        {
            context->window->close();
        }

        if (event.type == sf::Event::KeyPressed && event.key.code == sf::Keyboard::Return)
        {
            if (text_counter < (sizeof(text_array) / sizeof(text_array[0])))
            {
                text.setString(text_array[text_counter]);
                text_counter++;
            }
        }
    }
}

void GamePlay::Update(sf::Time deltaTime)
{
//    text.setString("Hello There");
//
//        text.setString("Hello Again");
}

void GamePlay::Draw()
{
    context->window->clear(sf::Color::Black);
    context->window->draw(chatBox);
    context->window->draw(text);
    context->window->display();
}

here it is:

void GamePlay::ProcessInput()
{

    unsigned int text_counter = 0;
    std::string text_array[] = {"This is the first text",
                                "This is the second one",
                                "And third text",
                                "End"};

    sf::Event event;
    while(context->window->pollEvent(event))
//[...]
 

you are recreating the 'text_counter' variable and assigning zero to it everytime the user press Return. so it will be always 0, and since the first item of arrays are 0, you are stuck on the first text.

move this variable to inside your GamePlay class, and assign a value to it in the Init() function:

class GamePlay{
unsigned int text_counter;
//[...]
};


void GamePlay::Init()
{
text_counter = 0;
//[...]
}

That helped thank you!
