General / checking collisions with array of objects takes too much

« on: May 28, 2024, 09:28:52 am »

Hi everyone. I have this button script:
Button.cpp

(click to show/hide)

#include "Button.h"


Button::Button(float x, float y, float width, float height,
   String text, Texture* image,
   Color idleColor, Color hoverColor, Color activeColor)
{
   ButtonS.setTexture(*image);
   ButtonS.setPosition(x, y);

   texture = *image;

   //ButtonT.setString(text);

   ButtonSetup(x, y, width, height, text, idleColor, hoverColor, activeColor);
}

Button::~Button()
{

}

void Button::setFont(Font* b_font)
{
   ButtonT.setFont(*b_font);
}

void Button::ButtonSetup(float x, float y, float width, float height, String text, Color idleColor, Color hoverColor, Color activeColor)
{
   ButtonState = BTN_IDLE;

   ButtonS.setPosition(x, y);
   ButtonS.setScale(width / ButtonS.getGlobalBounds().width, height / ButtonS.getGlobalBounds().height);

   font->loadFromFile("Resources/Edwardian.ttf");
   ButtonT.setFont(*font);
   ButtonT.setString(text);
   ButtonT.setFillColor(Color::Black);
   ButtonT.setPosition(x, y - ;
   ButtonT.setCharacterSize(28);

   ButtonBox = RectangleShape(Vector2f(width, height));
   ButtonBox.setPosition(x, y);

   this->activeColor = activeColor;
   this->hoverColor = hoverColor;
   this->idleColor = idleColor;
}

void Button::unPress()
{
   ButtonState = BTN_IDLE;
}

bool Button::isHover()
{
   if (ButtonState == BTN_HOVER)
      return true;
   return false;
}

const bool Button::isPressed() const
{
   if (ButtonState == BTN_ACTIVE)
      return true;
   return false;
}

void Button::ButtonBoxfunc(bool act, Vector2f mousePos, int thick, Color color)
{
   ButtonBoxAct = act;
   if (ButtonBoxAct)
   {
      //std::cout << "asd" << std::endl;
      ButtonBox.setOutlineColor(color);
      ButtonBox.setOutlineThickness(thick);
      ButtonState = BTN_IDLE;
      if (ButtonBox.getGlobalBounds().contains(mousePos))
      {
         ButtonState = BTN_HOVER;
         if (Mouse::isButtonPressed(Mouse::Left))
         {
            ButtonState = BTN_ACTIVE;
         }
      }
      if (ButtonState == BTN_IDLE)
         ButtonBox.setFillColor(idleColor);
      else if (ButtonState == BTN_HOVER)
         ButtonBox.setFillColor(hoverColor);
      else if (ButtonState == BTN_ACTIVE)
         ButtonBox.setFillColor(activeColor);

   }
}

void Button::updateEvented(Vector2f mousePos, Event event, bool fullColor)
{
   ButtonState = BTN_IDLE;
   if (ButtonS.getGlobalBounds().contains(mousePos))
   {
      ButtonState = BTN_HOVER;
      if (event.mouseButton.button == sf::Mouse::Left)
      {
         ButtonState = BTN_ACTIVE;
      }
   }
   if (fullColor)
   {
      if (ButtonState == BTN_IDLE)
         setColorB(idleColor);
      else if (ButtonState == BTN_HOVER)
         setColorB(hoverColor);
      else if (ButtonState == BTN_ACTIVE)
         setColorB(activeColor);
   }
   else
   {
      if (ButtonState == BTN_IDLE)
         ButtonS.setColor(idleColor);
      else if (ButtonState == BTN_HOVER)
         ButtonS.setColor(hoverColor);
      else if (ButtonState == BTN_ACTIVE)
         ButtonS.setColor(activeColor);
   }

}

void Button::render(RenderTarget* target)
{

   if (ButtonBoxAct)
      target->draw(ButtonBox);
   //target->draw(ButtonS);
   target->draw(ButtonT);
}

in short it just creates rectangleshape and text, chekcs its collision with mouse and returns it in "isPressed". My problem here is that when i try to create a vector with buttons it starts to freeze in some moments also taking up a lot of memory at these, i do it like this:
in game start function:

(click to show/hide)

for (int i = 0; i < 32; i++)
{
   int x = windowSize.width / 10 + i * 60;
   int y = windowSize.height / 1.7;
   if (i > 10)
   {
      y = windowSize.height / 1.5;
      x = windowSize.width / 10 + i * 60 - 10 * 60;
   }
   if (i > 19)
   {
      y = windowSize.height / 1.35;
      x = windowSize.width / 10 + i * 60 - 18 * 60;
   }
   if (i > 26)
   {
      y = windowSize.height / 1.23;
      x = windowSize.width / 10 + i * 60 - 24 * 60;
   }

   keyboardButtons.push_back(Button(x, y, 40, 40, alphabet, "", Color::White, Color::Yellow, Color::Blue));
}

in game update function:

(click to show/hide)

for (int i = 0; i < keyboardButtons.size(); i++)
{
   keyboardButtons.setFont(&font);
   keyboardButtons.updateEvented(mousePosView);
   keyboardButtons.ButtonBoxfunc(true, mousePosView, 5, Color::Black);
         if (keyboardButtons.isPressed())
         {
            //something
         }

}

at start i initialize buttons right to vector and in update check if button is pressed, the updateEvented checks collision and changes button states and buttonBoxfunc changes button color also helping to check collision creating box to collide with mouse
help me please to fix these freezes

Graphics / text output by character

« on: January 04, 2021, 02:57:36 pm »

this is how it must look, in console application:

(click to show/hide)

int main()
{
        string arr = "hello world";

        for (int i = 0; i < arr.size(); i++)
        {
                cout << arr[i];
                Sleep(1000);
        }
}
 

i also think it should look something like this in sfml:

(click to show/hide)

    std::string b;
    std::string arr = "hello world";
    while (window.isOpen())
    {
        float time = clock.getElapsedTime().asMilliseconds();
        time = time / 1000;
        if (time > 1)
        {
            for (int i = 0; i < arr.size(); i++)
                {
                b += arr[i];  
                e++;
                clock.restart();
            }
        }
       a.setString(b);
       window.draw(a);
}
 

but it doesn't work how i need, any hints please?

Graphics / Re: text doesnt show up in app

« on: December 02, 2020, 07:38:25 pm »

the 'e' variable (Text) is destroyed when the function ends, so there is no text at all to draw.
also, you don't have a font attached to the Text. and the text itself is not being drawn to any window.

thanks, that helpd. Now function looks like this

Text loadClass::buttonColor(Text e, int a, int b, int c, int d, RenderWindow& window )
{
        if (IntRect(a, b, c, d).contains(Mouse::getPosition(window)))
        {
                e.setFillColor(Color::Yellow);
        }
        else
        {
                e.setFillColor(Color::White);
        }
        return e;
}

also it needs to be in rendering function

void loadClass::buttonColor(RenderWindow& window, int a, int b, int c, int d, Text e)
{
    if (IntRect(a, b, c, d).contains(Mouse::getPosition(window)))
    {
        e.setFillColor(Color::Yellow);
    }
    else
    {
        e.setFillColor(Color::White);
    }
}

this fuctrion somewhy didnt work, help please! whats wrong?
