- Hello and welcome to Code Clinic.
My name is Dan Gookin.
Code clinic is a course where a unique problem is introduced
to a collection of lynda.com authors.
In response, each author creates a solution by using their
programming language of choice.
You can learn several things from Code Clinic,
different approaches to solving a problem,
the pros and cons of different languages,
and some tips and tricks to incorporate
into your own coding practices.
This chapter's problem is to create a musical instrument
controlled by using the mouse.
Move the mouse up and down to change the pitch,
move it side to side to change the volume.
The instrument is silent until a mouse button is held.
Letting go of the button turns off the musical tone.
It's a simple request, but because it requires access
to the mouse, it may be difficult or impossible
in some languages.
In all cases we'll explore some ways to solve the problem
and learn why they may not work.
Thomas Edison observed, "Negative results
"are just what I want.
"They're just as valuable to me as positive results.
"I can never find the thing that does the job best until
"I find the ones that don't."
You may want to take some time
to solve this problem yourself.
In the next few movies, I'll explain
how I answered this challenge.
