Add mouse_movement usage example

[ZGT23]

Description

Splashkit Function: mouse_movement

Overview of example functionality:
This pull request adds a beginner-friendly usage example for the mouse_movement function in the Input category.

The example opens a graphical window and displays the current mouse movement values in real time. It demonstrates how mouse_movement() returns the amount of mouse movement since the last process_events() call.

The program uses the movement vector to move a blue circle around the window. It also displays the X and Y movement values on screen and draws a red line to show the latest movement direction. This helps beginners understand the difference between mouse position and mouse movement.

Files Included

• C++ code
• C# code (Top-Level statements)
• C# code (Object-Oriented Programming)
• Python code
• Relevant title for the example (.txt)
• Screenshot

Usage Example Checks

• Code uses the SplashKit function above
• Code does not use non-SplashKit functions
• Code does not use extra function declarations or extra classes
• Simple, clear demonstration of the function
• Tested C++ version locally in MSYS2
• Tested Python version locally in MSYS2

How Has This Been Tested?

The example was tested locally to confirm that:

• The window opens correctly
• mouse_movement() values update when the mouse moves
• The blue circle reacts to the mouse movement vector
• The red line shows the latest movement direction
• C++ version runs correctly in MSYS2
• Python version runs correctly in MSYS2

I also checked existing pull requests and repository files before starting this task. I did not find an existing standard mouse_movement-1-example file set under public/usage-examples/input/. Although mouse movement is mentioned in older mouse input tutorial material, this PR adds a dedicated standard usage example for the mouse_movement function.

Testing Checklist

• C++ example tested locally
• Python example tested locally
• Tested in latest Chrome
• Tested in latest Firefox
• npm run preview

Additional Notes

This example is designed to be simple and beginner-friendly. It focuses on demonstrating how mouse_movement() works after process_events() without adding unnecessary complexity.

Approved.

I reviewed the added mouse_movement usage example files across C++, C# top-level, C# OOP, and Python. The examples are clear, beginner-friendly, and demonstrate the target SplashKit function well by showing how mouse movement values update after process_events() and how those values can be used to move an object on screen.

The file naming and structure are consistent with the existing usage example format, and the example focuses on the required function without adding unnecessary complexity. Overall, this is a suitable usage example for the Input category.

Good work.

Nice example - it’s clear, simple, and easy to follow. It demonstrates mouse_movement() really well.

Just one small thing - in the Python version, draw_text_no_font_no_size() is used instead of draw_text(). Just wanted to check if that was intentional, since most examples use draw_text().

Otherwise, everything looks good 👍
