Change to your 3350/2 folder and get source code from last week...


cd 3350/2
cp ../1/lab1.cpp lab2.cpp



Compile and run your program...


g++ lab2.cpp -Wall -lX11 -lGL -lGLU -lm -o lab2
./lab2

Create your git repository on Odin for this lab.

1. Change to your 3350 directory.

cd
cd 3350



2. Create a "bare" repository:


git init lab2.git --bare



You just created a bare git repo that will hold your lab-2 assignment.

3. Change back to your 3350/2 folder


cd 2



4. Create a (not bare) repository there:


git init
git add lab2.cpp
git add Makefile
git commit -m "my first commit"
git log



5. Push your project's master branch to the bare repository.


git push ../lab2.git master



Your git repository is now ready to be cloned remotely.
 
note:
The files in your 3350/2 folder are no longer needed,
but you may leave them in-place.

Do your lab coding on your local computer.

1. Go to the Desktop folder on your classroom computer.
   (Open a terminal and change to Desktop.)

2. Enter the following...


git clone yourname@odin:/~yourname/3350/lab2.git



   You will be asked for your password.
   A lab2 directory should now be on your local computer's Desktop.

   Your instructor will look for this directory.


3. Change to lab2, and enter the following:

   ls -al



   You should see your files and also the .git folder.
   When ready, build and run the lab2 program.

Note:
You can clone your repo from home or other off-site location by using
the complete Odin address. For example...


git clone yourname@odin.cs.csub.edu:/~yourname/3350/lab2.git



The tilde ~ takes you to your home directory.

Together we will modify the lab2.cpp program.

We already did some of this in class.

   1. Create a Makefile
  
   2. Refactor the program

This step is done anytime during class, or when the lab is complete.
From your local machine, update your git repository:


git add lab2.cpp
git commit -m "my changes during lab class"
git push origin master



note:
Do not execute: git add *   <----- no

What to do...

   1. Create your personal account on Github.
      Please make this a public account.

   2. Create a bare repository on Github named lab2

   3. Push your lab2.git repo to Github...

      DETAILS
      . Clone your lab2.git to your Desktop.
        Do the steps below from your Desktop/lab2 folder.
        (change to your lab2 folder)
      . Remove the .git folder


cd Desktop
cd lab2
pwd
rm -ri .git



      . Create a new repo


git init
git add *
git commit -m "my first commit for lab-2"



      . Set the remote origin (command provided by github)


(different for each student)



      . Push the repo up to your lab2 repository.


git push origin master



      . Github website has clear instructions on how to get this done.


   4. So that Gordon can clone your lab2 repository, you must provide your
      Github account name. Do it like this...

      a. Go to your Odin 3350/2 folder.

	  b. Create a text file named: my_github.txt

	  c. Enter the URL of your github account.
         
		 When you are at the home page of your github account, copy the
		 URL in the address field.

         Enter just 1-line into your file. No blank lines. No extra stuff.

         The string you enter will be used in a git clone command.
		 
         Gordon will append the /lab2, not you.		

         You can test this yourself.



git clone your-string/lab2



         Gordon will clone your repository this way.
         Do not put the /lab2 in your my_github.txt file.

Modify the lab2.cpp program.



Add the following functionality...

1. Make the color of the moving box change based upon the rate
   at which it is bouncing off the left and right walls.

   You can change the bounce-rate by changing the window size
   using the mouse.

   As the box bounces more frequently, make the color turn more red.
   As the box bounces less frequently, make the color turn more blue.

2. If the window width becomes smaller than the box width,
   there will be no bouncing, so make the box disappear.

3. Make the box go slightly up or down when it moves.
   Make it bounce off the floor and ceiling of the window.

4. Designate a key-press that will slow-down and speed-up the animation.

There are many different ways to code a solution to these things.
