Part 1 - Base Types

First we will need to declare some class types to store the information we will need like Flies, Fly receptacles, and a Scent object.

Because the flies and the player we see on screen could be considered actors that share similar qualities we will declare an Actor class and then create a Fly class that inherits from the Actor class. We will not create a player class because the player will not possess any unique qualities other then what is already provided by the actor class.





You will notice that the Fly class contains a generic collection of Receptor objects. Receptors are like little antenna that we will use for detecting any scent that the Receptor may come in contact with. The flies we will be using for this tutorial will only be using 2 receptors.


 
Next we will define a Scent class that will represent a scent in our application. The scent class contains properties like Strength which we will use to determine how large we should draw the scent on screen. It also contains two other properties DecayRate and DecaySpeed. DecayRate specifies how much the scent strength will be reduced. And DecaySpeed will be used to determine how fast to apply the DecayRate. The scent class also contains a field called Owner. Owner is not required in this tutorial, but it will be set to reference the player varible we will define later.
