Graphics / Re: sf::View - not working correct

« on: December 09, 2024, 08:33:40 am »

Sorry for the poor wording. I need to render a texture that I create using text. I've already found a solution:

(click to show/hide)

sf::View v = sf::View( sf::FloatRect( sf::Vector2f( cam->position.x - width / 2.0f + borderWidth + margin, cam->position.y - height / 2.0f + borderWidth + margin ), sf::Vector2f( width - 2 *( borderWidth + margin ) - scrollbar->size.x, height - 2 *( borderWidth + margin ) ) ) );

Graphics / sf::View - not working correct

« on: December 08, 2024, 11:20:53 am »

Hi! I tried positioning text in texture but my code now work. I think so SFML 2.6.2 not working correctly, because I think my code is correct. I use global coordinates for all objects and result is in screenshot. I think this red bar should be a hover of blue rect.

(click to show/hide)

ScrollableText::ScrollableText(std::wstring text) : Dialog(DialogType::ScrollableText) {

   border = sf::RectangleShape(sf::Vector2f(width, height));
   border.setFillColor(panelColor_dark);
   border.setPosition(cam->position.x-width/2.0f, cam->position.y-height/2.0f);

   rect = sf::RectangleShape(sf::Vector2f(width-2*borderWidth, height-2*borderWidth));
   rect.setFillColor(panelColor_normal);
   rect.setPosition(cam->position.x - width/2.0f + borderWidth, cam->position.y - height/2.0f+borderWidth);

   sf::Vector2f scrollbar_size = sf::Vector2f(16, height - 2.0f * borderWidth);

   textarea = new TextArea(text, cam->position, width - 2.0f*borderWidth - 2.0f*margin - scrollbar_size.x);
   textarea->setPosition(sf::Vector2f(- width/2.0f + borderWidth + margin, - height/2.0f + borderWidth + margin));

   sf::Vector2f scrollbar_position = sf::Vector2f(width/2.0f-borderWidth-scrollbar_size.x, -height/2.0f + borderWidth);
   float scroll_max = textarea->getSize().y + textarea->getLineHeight();
   float scroll_len = height;
   scrollbar = new Scrollbar(scrollbar_size, scrollbar_position, 0, scroll_max, 0, scroll_len);
   
   // TO-DO - generowanie tekstury przewijalnej dla tekstu
   text_texture.create(width-2.0f*(borderWidth+margin) - scrollbar_size.x, height-2.0f*(borderWidth+margin));
   sf::View v = sf::View(sf::FloatRect(sf::Vector2f(cam->position.x-width/2.0f+borderWidth+margin, cam->position.y-height/2.0f+borderWidth+margin), sf::Vector2f(width-2*(borderWidth+margin), height-2*(borderWidth+margin))));
   text_texture.setView(v);
   text_texture.setSmooth(true);
   text_texture.clear(sf::Color::Red);
   textarea->setRectColor(sf::Color::Blue);
   text_texture.draw(textarea->rect);
   for (auto& text : textarea->texts)
      text_texture.draw(text);
   text_texture.display();
   text_sprite = sf::Sprite(text_texture.getTexture());
   sf::Vector2f textpos;
   textpos.x = cam->position.x + position.x - width / 2.0f + borderWidth + margin - (textarea->texts[0].getPosition().x-textarea->rect.getPosition().x);
   textpos.y = cam->position.y + position.y - height / 2.0f + borderWidth + margin - (textarea->texts[0].getPosition().y - textarea->rect.getPosition().y);
   text_sprite.setPosition(textpos);
   // TO-DO
}
