JavaSpaces Principles DrawRay to explore how 3D vectors work Use Unity to visualize vectors in 3D Run the game to see the ray in the Scene view Add a duration to the ray so it leaves a trail Rotate your ball around a point in the scene Use Unity to take a closer look at rotation and vectors Get creative!
Private fields and methods can only be accessed from instances of the same class Why encapsulation? Are fields or methods being misused? Is there calculation required after setting a field? So what fields and methods really need to be public? Properties make encapsulation easier Replace the GetBalls and SetBalls methods with a property Modify your Main method to use the Balls property Debug your PaintballGun class to understand how the property works Auto-implemented properties simplify your code Use the prop snippet to create an auto-implemented property Use a private setter to create a read-only property Make the BallsLoaded setter private What if we want to change the magazine size?
When your classes use inheritance, you only need to write your code once Build up your class model by starting general and getting more specific How would you design a zoo simulator? Different animals have different behaviors Every subclass extends its base class C always calls the most specific method Any place where you can use a base class, you can use one of its subclasses instead Use a colon to extend a base class We know that inheritance adds the base class fields, properties, and methods to the subclass Create a new material inside the Materials folder Spawn a billiard ball at a random point in the scene Use the debugger to understand Random.
So we need a DefendHive method, because enemies can attack at any time We can use casting to call the DefendHive method An interface defines methods and properties that a class must implement The four core principles of object-oriented programming 8. Arrays can be annoying to work with Lists make it easy to store collections of Empty creates an empty sequence of any type Enumerable.
Create an enumerable sequence by hand Use yield return to create your own sequences Use the debugger to explore yield return Use yield return to refactor ManualSportSequence Add an indexer to BetterSportSequence Collectioncross Collectioncross Solution Reading and writing files: Save the last byte for me!
NET uses streams to read and write data Different streams read and write different things Things you can do with a stream: A FileStream reads and writes bytes in a file Write text to a file in three simple steps The Swindler launches another diabolical plan StreamWriter Magnets StreamWriter Magnets Solution Use a StreamReader to read a file Data can go through more than one stream Pool Puzzle Pool Puzzle Solution Use the static File and Directory classes to work with files and directories Things you can do with the static File class: Things you can do with the static Directory class: IDisposable makes sure objects are closed properly Use the IDE to explore IDisposable Avoid filesystem errors with using statements Use multiple using statements for multiple objects Use a MemoryStream to stream data to memory Use Encoding.
