Graphics / Re: Collision problems

That's the full code, you could test it yourself and see.
I can't really explain.
The best explanation is:
If I collide with right/left while holding D/A and the player is 1-99% higher/lower then wall, I can't move up/down.
You'd understand better if you'd test it yourself.

If you got a fix, could you just drop the code here?
I'm pretty good at reading not huge amounts of code.

Graphics / Collision problems

« on: February 18, 2014, 07:47:37 pm »

Hello there, I have a collision problem, I had a different one previously that I fixed by adding isMoving right/left etc.
But now, if I, for example collide with the wall that's on my right, my player is above(not completely) the top of the wall, I can't move left unless I release the right(D) button.
Here's my code w/o includes.

class variables{
public:
        float windowWidth{ 854 }, windowHeight{ 480 }, pixelWidth{ 1280 }, pixelHeight{ 720 }, pSize{ 32 }, pWidth{ pSize }, pHeight{ pSize }, pSpeed{ 1 }, groundSize{ 128 }, groundWidth{ 256 }, groundHeight{ groundSize };
};

class Player{
        variables vars;
public:
        sf::RectangleShape rect;
        bool moveUp{ false }, moveDown{ false }, moveLeft{ false }, moveRight{ false };
        double top, bottom, left, right;
        Player(sf::Vector2f position, sf::Vector2f size, sf::Color color){
                rect.setPosition(position);
                rect.setSize(size);
                rect.setFillColor(color);
        }
        void Update(){
                top = rect.getPosition().y;
                bottom = rect.getPosition().y + rect.getSize().y;
                left = rect.getPosition().x;
                right = rect.getPosition().x + rect.getSize().x;
        }
        void Collide(sf::RectangleShape r){
                double rLeft{ r.getPosition().x }, rRight{ r.getPosition().x + r.getSize().x }, rTop{ r.getPosition().y }, rBottom{ r.getPosition().y + r.getSize().y };
                if (top<rBottom&&bottom>rBottom&&left<rRight&&right>rLeft&&moveUp == true) { rect.move(0, vars.pSpeed); }
                if (bottom > rTop&&top < rTop&&left<rRight&&right>rLeft&&moveDown == true){ rect.move(0, -vars.pSpeed); }
                if (right>rLeft&&left < rLeft&&top<rBottom&&bottom>rTop&&moveRight == true){ rect.move(-vars.pSpeed, 0); }
                if (left<rRight&&right>rRight&&top<rBottom&&bottom>rTop&&moveLeft == true){ rect.move(vars.pSpeed, 0); }
        }
};
class Ground{
        variables vars;
public:
        sf::RectangleShape rect;
        Ground(sf::Vector2f position, sf::Vector2f size, sf::Color color){
                rect.setPosition(position);
                rect.setSize(size);
                rect.setFillColor(color);
        }
};
int main(){
        variables vars;
        Player player(sf::Vector2f(100,100), sf::Vector2f(vars.pWidth, vars.pHeight), sf::Color::Red);
        sf::RenderWindow window(sf::VideoMode(vars.windowWidth, vars.windowHeight), "SPEIS INVEIDRZ!!!1!");
        while (window.isOpen()){
                sf::Event Event;
                while (window.pollEvent(Event)){
                        if (Event.type == sf::Event::Closed){
                                window.close();
                        }
                }
                if (sf::Keyboard::isKeyPressed(sf::Keyboard::A)){
                        player.moveLeft=true;
                        player.rect.move(-vars.pSpeed, 0);
                }
                else{ player.moveLeft = false; }
                if (sf::Keyboard::isKeyPressed(sf::Keyboard::D)){
                        player.moveRight=true;
                        player.rect.move(vars.pSpeed, 0);
                }
                else{ player.moveRight = false; }
                if (sf::Keyboard::isKeyPressed(sf::Keyboard::W)){
                        player.moveUp=true;
                        player.rect.move(0, -vars.pSpeed);
                }
                else{ player.moveUp = false; }
                if (sf::Keyboard::isKeyPressed(sf::Keyboard::S)){
                        player.moveDown=true;
                        player.rect.move(0, vars.pSpeed);
                }
                else{ player.moveDown = false; }
                window.clear();
                player.Update();
                for (int i = 0; i < 5; i++){
                        Ground g(sf::Vector2f(i*vars.groundWidth, 500), sf::Vector2f(vars.groundWidth, vars.groundHeight), sf::Color::Blue);
                        window.draw(g.rect);
                        player.Collide(g.rect);
                }
                sf::View view(sf::FloatRect(player.rect.getPosition().x - vars.pixelWidth/2+vars.pWidth/2, player.rect.getPosition().y - vars.pixelHeight/2+vars.pHeight/2, vars.pixelWidth, vars.pixelHeight));
                std::cout << player.rect.getPosition().x << " " << player.rect.getPosition().y << std::endl;
                window.setView(view);
                window.draw(player.rect);
                window.display();
        }
        return 0;
}

So, any way to fix it?
