1. Include a 2-3 sentence explanation of how to make a window resizable (5 points) and a 2-3 sentence explanation of how to keep text centered in a resizing window (5 points).

   The window can be made resizable by using the FLAG_WINDOW_RESIZABLE flag when creating the window using the SetState method. This flag allows the user to adjust window size.

   To keep text centered in a resizing window, on every draw call, we can calculate the center position based on the screen width and height using GetWidth() and GetHeight() methods. Then, we have to calculate the text width using MeasureText() and setting the origin position of the text to be half of the text width and height. Using the DrawTextPro method allows us to use this origin position as an anchor point to keep the text centered, which is also useful for other transformations like rotation and scaling.

2. Include a 2-3 sentence explanation of what "cmake .." does. What is the importance of the ".."? (5 points.) Describe how to fetch your git submodules (5 points) with commands that can be copy and pasted into a Linux terminal (5 points).

   Running cmake .. tells CMake to generate the build files for the project by looking for CMakeLists.txt in the parent directory. Because building is done in a separate build directory within the project, it is necessary to use the ".." to point CMake to the root directory of the project, where the CMakeLists.txt file is located.

   git clone has an option to initialize and fetch submodules while cloning. However, if the repository has already been cloned, the git submodule update --init --recursive command can be used to fetch and initialize all submodules defined in the repository.

   git submodule update --init --recursive
   

3. Describe how to compile your code (10 points) with copy and pasteable commands [assume that we have cloned your repository and are in your as0 folder] (10 points).

   Make a build directory and enter it. Run cmake to generate the build files. Then, compile the code using make. The executable will be created in the build directory with the name "as0".

   mkdir -p build
   cd build
   cmake ..
   make
   

4. Describe how to run you’re code (10 points) and enumerate its controls [I predict "not applicable" will be the most common set of controls for this assignment.] (10 points).

   After compiling the code, the executable can be run from the build directory. The executable is named "as0" and can be started with ./as0

   There are no specific controls other than resizing the window, which changes how the text is displayed by remaining centered.

5. If you have any extra credit make sure to mention it so we don't miss it.

   The text is animated as it continuously rotates 22.5 degrees per second.
