simple game by c++/sfml

Primary LanguageC++

Space game using c++/sfml

idea of works

We have main components are:

  • player
  • enemy

Player implement as circular shape:

sf::CircleShape player(30);
player.setFillColor(sf::Color::Green);
player.setPosition(sf::Vector2f(screen.width/2,screen.height/4));
player.setOutlineThickness(3);
player.setOutlineColor(sf::Color::Blue);

Enemy ship implement as ConvexShape:

int numOfb=20;
sf::ConvexShape c[numOfb];
for(int i=0;i<numOfb;i++)
{
c[i].setPointCount(4);
c[i].setFillColor(sf::Color::Red);
c[i].setPoint(0,sf::Vector2f(100,100));
c[i].setPoint(1,sf::Vector2f(200,0));
c[i].setPoint(2,sf::Vector2f(0,0));
c[i].setPoint(3,sf::Vector2f(100,0));
c[i].setPosition(rang(ran)+screen.width,rang(ran));
}

When player collides with enemy ship will lost, else than will win after 30 sec.

for(int i=0;i<numOfb;i++)
{
    if(player.getGlobalBounds().intersects(c[i].getGlobalBounds()))
    {
    ifLoss=true;
    player.setOutlineColor(sf::Color::Red);
    }
}

build

for linux :

  1. $ sudo apt-get install libsfml-dev
  2. go to app/src/main/jni/
  3. $ g++ -c main.cpp
  4. $ g++ main.o -o sfml-app -lsfml-graphics -lsfml-window -lsfml-system
  5. $ ./sfml-app

for android:

  1. first should have: - android SDK [https://developer.android.com/studio] - android NDK [https://developer.android.com/ndk] - gradle [https://gradle.org/]
  2. build SFML for android [https://github.com/SFML/SFML/wiki/Tutorial%3A-Building-SFML-for-Android]
  3. go to root of project will see local.properties file open it in text editor, and change paths of SDK and NDK
  4. open CLI and type gradle build
  5. plug your android phone using USB.
  6. also on root folder of project open CLI and type gradle installDebug
  7. you will see app install on your phone

Flow of work

1-first run

2-avoid enemy

3-win after 30 sec

4-collided enemy

5-game over
