Fighting for score
We've got a lot in place; now we just need to put these parts together in another way

Bullet
class; this will allow us to control the movement of
the bullet and easily manage lifetime and damage.
class Bullet
{
private:
RectangleCollider *_collider;
std::shared_ptr<Sprite> _sprite;
bool _isAlive;
public:
int Damage;
Bullet();
~Bullet();
void Load();
RectangleCollider* GetCollider() { return
_collider; }
void SetPosition(XMFLOAT2 topleft);
void MoveForward(float deltaTime);
void Destroy();
void Respawn();
bool GetIsAlive();
};
There's quite a bit in here, but most of it you have seen before. We need a
Sprite
and a collider for the bullet so that we can display it and easily check for collisions
with the enemy. We use
SetPosition
to set the initial position when we spawn the
