SFML projects / Re: Space shooting Game

i've said that stl containers are much more easy to use but i just said how i did it:D and i used that kind of list because i wanted to understand the mechanic behind, and is an great learning exercise

You could also use linked lists for both asteroids and bullets, same as stl containers.You add an element to the list every time you want to (have an new bullet or an new asteroid)
and this is the code for adding an new element
and the code for the struct
i used lists, but stl containers are much more easy and 'bug preventive' to use
if(sf::Keyboard::isKeyPressed(sf::Keyboard::Space))
{
while(acumulator > interval) //i test so that you cannot shoot many bullets per second
{
sf::Vector2f f=this->getPozitie();//get the position of the player
f.x+=this->dimensiune.x-3;//place the 'bullet position' in front of the player, f is an empty variable
f.y+=this->dimensiune.y/2-3;
this->Arma.fuel(f);//this command adds one bullet to the list
acumulator5-=intervall;
}
}
{
while(acumulator > interval) //i test so that you cannot shoot many bullets per second
{
sf::Vector2f f=this->getPozitie();//get the position of the player
f.x+=this->dimensiune.x-3;//place the 'bullet position' in front of the player, f is an empty variable
f.y+=this->dimensiune.y/2-3;
this->Arma.fuel(f);//this command adds one bullet to the list
acumulator5-=intervall;
}
}
and this is the code for adding an new element
p=new glont;//the type of struct of the list
p->sprite.setTexture(texture);//texture
p->pozitie=poz;//position
p->sprite.setPosition(p->pozitie);//set the position also to the sprite
q->next=p;//setting the last bullet reference to this one
p->sprite.setTexture(texture);//texture
p->pozitie=poz;//position
p->sprite.setPosition(p->pozitie);//set the position also to the sprite
q->next=p;//setting the last bullet reference to this one
and the code for the struct
struct glont{
sf::Sprite sprite;
sf::Vector2f pozitie;
glont *next=NULL;
};
sf::Sprite sprite;
sf::Vector2f pozitie;
glont *next=NULL;
};

for the background i have just 2 identical sprites and the black bar occurs because i update all the elements by time and there are differences (like 0.001 seconds) between the update of each image

game over is when your score goes below 0, but i will change de mechanics 
i fixed the left+right and up+down arrows bug , thx:D i will do the player-ship colision soon

What do you think? it's a game in progress.
You move by arrows, shoot by space.Sometimes bonuses apear on the screen, if you run into them you shoot faster.
Start by pressing 's'

some screenshots:

http://i.imgur.com/UAFmkLg.png?1 yeah , that is an bullet
http://i.imgur.com/bHflEuB.png?1 bonus with timer
in order to win, you have to score around 700 points, and you loose if you go below 0;for each monster that exit the screen you loose 30;

Hey guys. I am making an Space invaders type of game, and i want to make some power-ups.I want to make an animation for that, like an loading circle so that user can know how much time left he has to take the power-up.I know how to do that by sprites(5-6 sprites with 1/5-1/6 of circle and just display the images after a time) but i want to do it smoothly, and by that i mean to calculate the % of circle to fill based on the time i want.I guess it can be done with texture updating...but i don't know

return 0;
}
My problem is that if i use sprite.setScale(0.5,0.5) it works but if i use sprite.setScale(newsezia,newsizeb) it doesn't work.I don't know why the setScale doesn't work if i use variables but with numbers it works.
