Window / [solved] joystick detection

« on: October 13, 2024, 05:22:35 pm »

hi

i detect if a joystick is plugged, if not, i loop to detect the plugged one. but detects nothing

thanks

void Player::setJoystickID()
{
    unsigned int pluggedJoystickNumber{0};
    while(pluggedJoystickNumber == 0) {
        sf::Joystick::update();
        for (auto i = 0; i < sf::Joystick::Count; ++i) {
            if (sf::Joystick::isConnected(i)) { ++pluggedJoystickNumber; }
        }
        if (pluggedJoystickNumber == 0) {
            std::cout << "no joystick plugged" << std::endl;
            sf::sleep(sf::milliseconds(1000));
        }
        if(pluggedJoystickNumber == 1) { m_joystickID = 0; }
    }
}

Graphics / [solved] shifting center on rotation

« on: April 20, 2024, 01:42:17 am »

hi

i have my drawables witch have their centre shifted 1 pixel x and y when i rotate them
i choosedodds width and height to have a real center point for the rotation
sprite are 49 * 35 i use setorigin(24,17)
tried 48 * 34 in texturerect or vertexbuffer but no

i don't know how to get rid of that. tried with

made a simple program with sf::sprites and it's the same

thx

original on bottom rotated above. red dot should always be in black roof

#include <SFML/Graphics/RenderWindow.hpp>
#include <SFML/Graphics/CircleShape.hpp>
#include <SFML/Graphics/Sprite.hpp>
#include <SFML/Graphics/Texture.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(300, 300), "Test divers", sf::Style::Close);

    sf::Texture texture;
    texture.loadFromFile("cars.png");
    sf::Sprite car;
    car.setTexture(texture);
    car.setTextureRect(sf::IntRect(0,0,49,35));
    car.setOrigin(24, 17);
    car.setPosition(150,150);
    sf::CircleShape circle(1);
    circle.setFillColor(sf::Color::Red);
    circle.setPosition(car.getPosition());

    window.clear(sf::Color::White);

    window.draw(car);
    window.draw(circle);
    car.setPosition(150,90);
    car.setRotation(180);
    window.draw(car);
    circle.setPosition(car.getPosition());
    window.draw(circle);

Graphics / draw function with several drawable in an object

« on: July 21, 2023, 02:35:06 pm »

hi

i have an object drawable with 5 sf::Sprite and a bitmapText
i did first this draw function before i tried to make the object drawable

void BottomPanel::draw()
{
   for(auto i = 0; i < 5; ++i) {
         m_window.draw(*m_sprites[i]);
    }
    m_window.draw(m_Text);
}


}

was good, tranformation are drawn good

now i have this

void BottomPanel::draw(sf::RenderTarget& target, sf::RenderStates states) const
{
    for(auto& elem : m_sprites) {
        states.transform *= elem->getTransform();
        states.texture = elem->getTexture();
        target.draw(*elem, states);
    }

    states.transform *= m_Text.getTransform();
    states.texture = m_Text.getTexture();
    target.draw(m_Text, states);

}

i have a problem with the states.transform *= m_Text.getTransform();
sprites are not drawn where it should be

it's ok if i remove these 2 lines

how do I "fix" a position coords for my object, then i can adapt sprites coords by this origin ?

the contained objects are sf::Transformable so if i set a rotation it s drawn good without
states.transform *= m_Text.getTransform();

so do i need to get transform or not ?
same with textures ?

draw what i want with that one

void BottomPanel::draw(sf::RenderTarget& target, sf::RenderStates states) const
{
    for(auto& elem : m_sprites) {
        target.draw(*elem, states);
    }
    target.draw(m_Text, states);
}

thx

Graphics / my getGlobalBounds()

« on: June 10, 2023, 05:02:51 pm »

hi

i made a bitmap and sf::text button 

class Button : public sf::Drawable, public sf::Transformable

with position and size being

sf::FloatRect                   m_shape;

initialized like this and origin is set in the constructor to be le middle

mylib::Button button(sf::FloatRect(320, 200 ,150, 100), texture, sf::Vector2f(230, 1600));
    button.rotate(90);
    button.setButtonType(mylib::Button::ButtonType::release);
    button.setScale(sf::Vector2f(2,2));
    button.setFont("OneSlot.ttf");
    button.setTextSize(30);
    button.setTextColor(sf::Color::Red);
    button.setText("the button");
 

my pb is i don't have a getGlobalBounds() available

so i tried this

sf::FloatRect Button::getGlobalBounds() const
{
    return getTransform().transformRect(m_shape);
}

width and height are good but left = -180 and top = 690

how do i have the good values ??

thx

didn't realised that setpostion() and vextex coord are already the same

working good

Graphics / Re: animation class bad coord drawing

« on: May 12, 2023, 04:07:34 am »

must be with the transform because when i remove

states.transform *= getTransform();

from the draw it's ok for coords but of course it's no longer a transformable

how do i fix ?

thx

Graphics / animation class bad coord drawing

« on: May 12, 2023, 03:24:23 am »

hi

i wrote an animation class.
the animation plays well but not where it should that seems to be drawn at coords * 2

can't find what i'm doing wrong. did cout to see coords in console and they are goods

minimal code representing a sprite

main.cpp

#include <SFML/Graphics/RenderWindow.hpp>
#include "bitmap/animation/animation.hpp"
#include "mysprite.hpp"

int main()
{
    sf::RenderWindow window(sf::VideoMode(600, 600), "tests divers", sf::Style::Close);
    MySprite mysprite;
    mysprite.m_texture.loadFromFile("countdown.png");
    sf::Vector2f coords(275,275);
    mysprite.setPosition(coords);

    sf::Vector2f framecoord = mysprite.getPosition();
    float LeftX = framecoord.x;
    float RightX = framecoord.x + 49;
    float topY = framecoord.y;
    float bottomY = framecoord.y + 49;

    mysprite.m_frame[0].position = sf::Vector2f(LeftX, topY);
    mysprite.m_frame[1].position = sf::Vector2f(RightX, topY);
    mysprite.m_frame[2].position = sf::Vector2f(RightX, bottomY);
    mysprite.m_frame[3].position = sf::Vector2f(LeftX, bottomY);

    mysprite.m_frame[0].texCoords = sf::Vector2f(0, 0);
    mysprite.m_frame[1].texCoords = sf::Vector2f(49, 0);
    mysprite.m_frame[2].texCoords = sf::Vector2f(49, 49);
    mysprite.m_frame[3].texCoords = sf::Vector2f(0, 49);

    while(1) {
        window.clear();
        window.draw(mysprite);
        window.display();
    }
}

animation .cpp

#include "mysprite.hpp"

bool MySprite::loadTexture(std::string& fileName)
{
    return m_texture.loadFromFile(fileName);
}

void MySprite::draw(sf::RenderTarget& target, sf::RenderStates states) const
{
    states.transform *= getTransform();
    states.texture = &m_texture;
    target.draw(m_frame, 4, sf::Quads, states);
}
 

animation.hpp

#ifndef MYSPRITE_CPP
#define MYSPRITE_CPP

#include <SFML/Graphics.hpp>

class MySprite : public sf::Drawable , public sf::Transformable {
    public :

hi

tested this code to see if my gamepad was detected, but no
ok with steam and dowloaded joystick tester and ok with it.
also ok in windows joystick configuration

thanks

#include <iostream>

#include <SFML/Window/Joystick.hpp>

int main()
{
    unsigned int joystckID{0};
    sf::Joystick myJoystick;
    while(joystckID < 8) {
        if (myJoystick.isConnected(joystckID)) {
            unsigned int buttonCount = myJoystick.getButtonCount(joystckID);
            std::cout << "joystick ID " << joystckID << " conneted with"  << buttonCount << " buttons.\n";
        }
        else { std::cout << "joystick ID " << joystckID << " not conneted\n"; }
        ++joystckID;
    }
    while(1) {
        if (sf::Joystick::isButtonPressed(0, 1)) { std::cout << "button 1 pressed\n"; }

the music begins
and when a soud is played, the music "volume" is lowered .
after few seconds the musoic "volume" up to the normal.
the set music volume is only set at the beginning
so i don t understand why the music is low then re-up
