The Particle class

The Particle class is the class we will use to represent the individual particles that are emitted by our particle system. The Particles class will need to be created with a constructor and later updated with an Update function used to modify the defining attributes of the particle. There will be a Spawn function used to activate the Particle, a Move function to move the particle through its life cycle eventually deactivating it, and a Render function that will perform the SDL rendering tasks required to draw the particle to the canvas. Here is what the Particle class looks like in our game.hpp file:

class Particle {
    public:
        bool m_active;
        bool m_alpha_fade;
        SDL_Texture *m_sprite_texture;
        int m_ttl;
        Uint32 m_life_time;
        float m_acceleration;
        float m_alpha;
        Point m_position;
        Point m_velocity;
