Graphics / Re: Fill sf::Sprite with constant color

« on: November 24, 2017, 05:21:27 pm »

I used this one

#define SHADER_WHITE                                          \
        "uniform sampler2D texture;                             " \
        "                                                       " \
        "void main() {                                          " \
        "    vec4 pixel = texture2D(texture, gl_TexCoord[0].xy);" \
        "                                                       " \
        "    pixel.r = 1.0f;                                    " \
        "    pixel.g = 1.0f;                                    " \
        "    pixel.b = 1.0f;                                    " \
        "                                                       " \
        "    gl_FragColor = pixel;                              " \
        "}                                                      "

Graphics / Re: Mac OS X - High Sierra - RenderTexture::clear

« on: November 22, 2017, 04:09:44 pm »

I tried to reproduce this issue on my laptop but couldn't. Since I haven't upgraded to High Sierra yet, I also tested in a VM but still couldn't reproduce the issue.

Now, using a VM is far from perfect to test such things, but it would be great if this bug could be reproduced by someone else using similar hardware as you do.

BTW, (if there's a bug) I'm not sure it's the same bug as #1132; the symptoms look too different.

Thanks for your time Laptop is "Pro Mid 2014" as I know.
Yeah, probably app will work fine on other configurations, but I made drawing black square just for sure

Drawables have different sizes, also you making duplicates. try to use pointers.

std::vector<sf::Drawable*> vectorOfDrawableObjects;


int GraphicsEngine::addToVector(sf::Drawable* drawableObject)
{
        vectorOfDrawableObjects.push_back(drawableObject);
        int objectNumber = vectorOfDrawableObjects.size();

        return objectNumber;
}


void GraphicsEngine::callObjectsDraw(sf::RenderWindow& window)
{
        for (int i = 0; i < vectorOfDrawableObjects.size(); i++)
        {
                window.draw(*vectorOfDrawableObjects[i]);
        }
}

SFML projects / Re: Screenshot Thread

« on: November 19, 2017, 09:22:52 pm »

Made for a couple of hours. Working on next project for Steam 
https://github.com/achpile/arcade

(at this moment to launch snake you should create ArcadeSnake() instead of ArcadeArkanoid() in the main.cpp)

Graphics / Re: Getting position of the circle that is rotated around a point

« on: November 19, 2017, 05:22:25 pm »

x = c.x + r*cos(a)
y = c.y + r*sin(a)

(c) is the center of rotation
(r) is radius
(a) in radians

radian = degree * 3.14 / 180

Window / Re: Problem with Button pressed

Yes, but since the OP really seems to understand very little about what he's doing, I'd avoid suggesting "complicated" custom solutions and focus on the obvious one first.

Oh, yes, sure 

I have the feeling that this code would really look better with events.

That's why I love SFML. You can achieve result by different ways and everyone can choose which one fits better

But using events is much better.

Depending on situation I use keyboard and gamepad settings for same actions and it looks like this

bool ach::Control::check() {
        bool result = false;

        if (sf::Keyboard::isKeyPressed(keyCode)) {
                result = true;
        }

        if (!useAxis) {
                if (sf::Joystick::isButtonPressed(joyID, joyCode)) {
                        result = true;
                }
        } else {
                if ((movAxis ==  1.0f && sf::Joystick::getAxisPosition(joyID, joyAxis) >  GAMEPAD_SENSETIVITY) ||
                    (movAxis == -1.0f && sf::Joystick::getAxisPosition(joyID, joyAxis) < -GAMEPAD_SENSETIVITY)) {
                        result = true;
                }
        }


        return result;
}
 

void ach::ControlKey::update() {
        if (!ctrl) return;

        bool newState = ctrl->check();

        if ( newState && newState != state) pressed = true;
        else                                pressed = false;

        if (!newState && newState != state) released = true;
        else                                released = false;

        state = newState;
}

or you can init it on constructor with current value of isButtonPressed

Because button was pressed for multiple "ticks". If you wanna handle event - handle sf::Event. Or implement own class kinda

newState = sf::Joystick::isButtonPressed

if (oldState != newState && newState) isPressed = true;
else isPressed = false;

oldState = newState

if (sf::Joystick::getAxisPosition(joyID, joyAxis) >  GAMEPAD_THRESHOLD)

What is the value of GAMEPAD_THRESHOLD?

i use 50.0f
