Time for action – player shot collisions

1. Add the checkShotToEnemy() method to the CollisionManager class:

   Private Sub checkShotToEnemyCollisions()
       For Each shot As Sprite in _playerManager.PlayerShotManager.Shots
           For Each thisEnemy As Enemy in _enemyManager.Enemies
               If shot.IsCircleColliding(
                   thisEnemy.EnemySprite.Center,
                   thisEnemy.EnemySprite.CollisionRadius) Then
   
                   shot.Location = offScreen
                   thisEnemy.Destroyed = true
                   _playerManager.PlayerScore += enemyPointValue
                   _explosionManager.AddExplosion(
                       thisEnemy.EnemySprite.Center,
                       thisEnemy.EnemySprite.Velocity/10)
               End If
           Next
       Next
   End Sub

2. Add the checkShotToAsteroid() method to the CollisionManager class:

   Private Sub checkShotToAsteroidCollisions()
       For Each shot As Sprite in _playerManager.PlayerShotManager.Shots
           For Each asteroid As Sprite in _asteroidManager...
