Class 8, Assignment 2: Adding a Scoreboard in Greenfoot

Beards, Bugs, and Bacon!

http://www.greenfoot.org/scenarios/9720

JoC #16:

Here I added a counter that keeps score and fixed the left over bug from JoC#15

JoC #17:

Here I used the Bounce scenario to build a complete class object that contained constructors, fields, and Act methods. 

JoC #18:

This exercise taught me to add an Act Method to the World Class in order to enable a ball to appear wherever the mouse is clicked within the environment.

JoC #19:

Internal, External, and Instanced Methods are reviewed.

JoC #20:

Here I had more practice with object interaction. - specifically manipulating the background image through the world constructor.

JoC #21:

Here I learned to assign random variables to the ball class.  The resulting effect is that when you click into the environment, you'll get a random color, random transparency, random speed, and random direction to every ball.

JoC #22:

This episode simple had us refactor our previous code, which essentially just means cleaning it up and making it more cohesive.

JoC #22 Tracing Control Flow:

Here we learned how to troubleshoot our code by using line breaks and the debugger tool.

JoC #23:

Here we constructed our first full If Statement that causes the balls to fade away and removed themselves from the environment.

JoC #24:

This was simply an introduction and overview on how to one might apply the skills already covered in the previous 23 JoC videos.  (and a not so shameless marketing attempt at selling us the Greenfoot book.)

JoC #25:

This was simply an overview of the various errors a programmer might make and how to go about fixing them.
