Graphics / cannon and bullet

« on: May 22, 2015, 08:10:18 pm »

what would be the best idea to write cannon and bullets?

class Bullet : pubic Cannon{};

or write them separately?

Graphics / sprite filled with white color

« on: May 17, 2015, 05:50:09 pm »

it says that you will get white screen when the texture the sprite is pointing is no longer alive.

heres my constructor

WeirdAlien::WeirdAlien()
{
    _sprite.setTexture(loadAlien());
    alien_position[ctr].x = ctr * 32;
    ++ctr;
}

void drawAlien(const int alien_count,const std::vector<Alien*>alien,const bool isAlienAlive[6],sf::RenderWindow& game_window)
{
    for ( int a = 0; a < alien_count; a++ )
        if (isAlienAlive[a])
            game_window.draw(alien[a]->setSprite());
}

im still getting white square problem, why?

can someone test my program?
here is the code: http://pastebin.com/4QwmkZX6
and download the images below and put the folder in the working directory.

if you notice,
if you play it slowly the game is fine,
but when you try to play it like spamming the key and mouse left button you will notice theres sometimes extra images appearing at 0,0 coordinate of window

Graphics / texture and sprite

« on: May 09, 2015, 06:15:07 pm »

Can i load more than one image to texture and set texture to sprite?

example:
sf::Texture texture;
texture.loadFromFile("image1.png");
texture.loadFromFile("image2.png");

does the image1 get destroyed? if not how can i choose which image i want to render.
example:
sprite.setTexture(texture.choosewhatiwanttoset("image1.png"));
sprite.setTexture(texture.choosewhatiwanttoset("image2.png"));
...
same question for sprite,
window.draw(sprite.choosewhatiwanttorender("image1.png"));

thanks

Ive been trying to figure out my problem for a week and and i have searched thouroughly in google
