Time for action – the Particle class

1. Add a new class called Particle to the Robot Rampage project.

2. Update the class declaration for the Particle class to derive it from the Sprite class by adding an Inherits line below the class declaration:

   Inherits Sprite

3. Add declarations to the Particle class:

   #Region "Declarations"
   Private _acceleration As Vector2
   Private _maxSpeed As Single
   Private _initialDuration As Integer
   Private _remainingDuration As Integer
   Private _initialColor As Color
   Private _finalColor As Color
   #End Region

4. Add properties to the Particle class:

   #Region "Properties"
   Public ReadOnly Property ElapsedDuration As Integer
       Get
           Return _initialDuration - _remainingDuration
       End Get
   End Property
   
   Public ReadOnly Property DurationProgress As Single
       Get
           Return CSng(ElapsedDuration) / CSng(_initialDuration)
       End Get
   End Property
   
   Public ReadOnly Property IsActive As Boolean
       Get
           Return (_remainingDuration > 0)
       End Get
   End Property
   #End Region
