Graphics / Question about sprite moving

« on: August 10, 2013, 10:27:07 am »

I can keep the sprite on the screen, but my problem is when it reaches the end of screen, it cant go back left, And if I continue pressing key it lefts the screen.

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow Window(sf::VideoMode(320,320),"");
    sf::Texture tex;
    tex.loadFromFile("bullet.png");
    sf::Sprite sprite(tex);
    float movespeed = 0.1f;
    float velocityX = 0;
    while(Window.isOpen())
    {
        Window.clear();
        Window.draw(sprite);
        Window.display();
        sf::Event Event;
        while(Window.pollEvent(Event))
        {
            switch(Event.type)
            {
            case sf::Event::Closed:
                Window.close();
            }
        }
        if(sprite.getPosition().x + 9 > 320 || sprite.getPosition().x < 0)
            velocityX = 0;
        if(sf::Keyboard::isKeyPressed(sf::Keyboard::Right))
        {
            velocityX = movespeed;
            sprite.move(velocityX,0);
        }
        else if(sf::Keyboard::isKeyPressed(sf::Keyboard::Left))
        {
            velocityX = -movespeed;
            sprite.move(velocityX,0);
        }
    }
}

Yes thats what I want but what will I use to make ballx negate when it reaches the end of X of screen?

Im trying this code but its wrong..

#include <SFML/Graphics.hpp>

int main()
{
    int screen_w = 640;
    int screen_h = 480;
    sf::RenderWindow window(sf::VideoMode(screen_w,screen_h), "SAMPLE");
    sf::Image image;
    image.loadFromFile("ball.png");
    image.createMaskFromColor(sf::Color(255,0,255));
    sf::Texture texture;
    texture.loadFromImage(image);
    sf::Sprite sprite(texture);
    float ballx = 0.1;
    float bally = 0.0;
    while(window.isOpen())
    {
        sprite.move(ballx,bally);
        window.clear();
        window.draw(sprite);
        window.display();

        sf::Event event;
        while(window.pollEvent(event))
        {
            if(sf::Keyboard::isKeyPressed(sf::Keyboard::Escape))
            window.close();
        }
        if(sprite.getPosition().x <= screen_w-20)
        ballx = -0.1;
    }
}

How can I make the ball bounce back if it reaches the end of the screen?

#include <SFML/Graphics.hpp>
int main()
{
    int screen_w = 640;
    int screen_h = 480;
    sf::RenderWindow window(sf::VideoMode(screen_w,screen_h), "SAMPLE");
    sf::Image image;
    image.loadFromFile("ball.png");
    image.createMaskFromColor(sf::Color(255,0,255));
    sf::Texture texture;
    texture.loadFromImage(image);
    sf::Sprite sprite(texture);
    float ballx = 0.1;
    float bally = 0.0;
    while(window.isOpen())
    {
        sprite.move(ballx,bally);
        window.clear();
        window.draw(sprite);
        window.display();
               
        sf::Event event;
        while(window.pollEvent(event))
        {
            if(sf::Keyboard::isKeyPressed(sf::Keyboard::Escape))

            }
            if(sf::Keyboard::isKeyPressed(sf::Keyboard::Right))
            {
            ballx = 0.1;
            bally = 0.0;
            }
            if(sf::Keyboard::isKeyPressed(sf::Keyboard::Down))
            {
            bally = 0.1;
            ballx = 0.0;
            }

Thank you so much, I didnt know that I have to link sfml-system because sf::Text is part of sfml graphics module.

Graphics / Help in Animation.

« on: December 13, 2011, 04:21:11 am »

I got a problem when I try to press the keyboard key A.
My animation stops when I hold down the Keyboard key A.

Code: [Select]

#include "SFML/Graphics.hpp"
#include "SFML/System.hpp"
#include "AniSprite.h"

int main()
{
    sf::RenderWindow App(sf::VideoMode(640, 420,32), "Test");

sf::Image Image;

if (!Image.LoadFromFile("untitled1.bmp"))
return 1;
Image.CreateMaskFromColor(sf::Color::Black);

sf::Texture Texture;
Texture.LoadFromImage(Image);

AniSprite Sprite(Texture,93,96);
Sprite.SetLoopSpeed(0.007); //60 fps




while(App.IsOpened())
{
    sf::Event Event;

    while (App.PollEvent(Event))
    {
        if (Event.Type == sf::Event::Closed)
                App.Close();
        if ((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Keyboard::A))
                Sprite.Play();
        else if ((Event.Type == sf::Event::KeyReleased) && (Event.Key.Code == sf::Keyboard::A))
                Sprite.Stop();

    }

    App.Clear();
    Sprite.Update();
    App.Draw(Sprite);
    App.Display();
}
}

Graphics / AniSprite Error

« on: December 11, 2011, 02:03:58 pm »

Yeah I know sir, Thats why im asking if this is fully implemented in sfml 2.
Because I know that sf::Image will pass to sf::Texture first before passing to sf::Sprite..
