Add Vector Generation Physics Usage Examples

[ShaunR1991]

Description

This pull request adds simple usage examples for the following vector generation functions in SplashKit:

• unit_vector
• vector_from_angle
• vector_from_line
• vector_from_point_to_rect
• vector_invert
• vector_limit
• vector_normal
• vector_out_of_circle_from_circle
• vector_out_of_circle_from_point
• vector_out_of_rect_from_circle
• vector_out_of_rect_from_point
• vector_out_of_rect_from_rect
• vector_point_to_point
• vector_to
• vector_to_point

The purpose of this update is to help users understand the functionality of these vector generation functions in SplashKit by providing detailed examples across supported languages (C++, C#, and Python).

Each example includes:

• C++ Code
• C# Code (Top-Level and Object-Oriented versions)
• Python Code
• Text Description File
• Image of Output (if applicable)

No resource zip files are required for these examples.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation (update or new)

How Has This Been Tested?

All functions were run and tested to ensure output was as expected.

Testing Checklist

• Tested in latest Chrome
• Tested in latest Firefox
• npm run build
• npm run preview

Checklist

If involving code

• My code follows the style guidelines of this project
• I have performed a self-review of my own code
• I have commented my code in hard-to-understand areas
• I have made corresponding changes to the documentation
• My changes generate no new warnings

If modified config files

• I have checked the following files for changes:
  • package.json
  • astro.config.mjs
  • netlify.toml
  • docker-compose.yml
  • custom.css

Additional Notes

Each example is designed to demonstrate only the basic functionality of vector generation functions in SplashKit. The resources provided will enable users to replicate, modify, and understand how to implement the functions and what the expected outputs might look like.

• All required files are present.
  • Title and explanation (.txt)
  • C++ code
  • C# code (top-level statements)
  • C# code (Object-Oriented Programming)
  • Python code
• Code correctly uses Splashkit functions.
• Code clearly demonstrates the function.
• All versions maintain the same structure and comments.
• C++ code ran correctly.
• C# top level code ran correctly.
• C# OOP code ran correctly.
• Python code ran correctly.

Feedback:
In these code files
vector_out_of_circle_from_circle-simple.cpp
vector_out_of_circle_from_point.cpp
vector_out_of_rect_from_circle.cpp

the line outer_circle.center = {150, 150}; produces an error for invalid syntax. C++ requires explicit construction of structs like point_2d.

Thanks for the thorough review and good spot. Changes made and checked. Working as intended!
