Physics2DLibrary 0.7.4

2D Physics Library

This is a junior-in-school's first public library. As of now, it contains a variety of base objects for base 2D physics; there's a Rotation to handle orientation, a Point to handle positions, Lines that are pairs of points, and Vectors that hold a rotation and magnitude. None of these classes are done, but all of the base classes are in place. In the works are a few objects that are collections of points or vectors, and they will handle collisions and such. I just haven't figured out how to best make it yet.

I add XML Comments (the ones VS Code and Visual Studio usually read for their Intellisense) to every property, method, and class, so I hope those are of a bit more use to you than a generalized readme. There is an external documentation page that you can look at right now to read through all of the classes that are ready to be used. They should be pretty stable, just making more methods and tests for them.

Changelog

0.7.4 (3/5/2025)

• SOME BREAKING CHANGES: Adjusted class names to more closely align with the library name, and the Equation name conflict.
  • There's a default class with the name Equation, so I had to rename everything.. welp!
  • Rotation2D no longer supports Radians. A second RotationRadian2D class will be added to work with radians instead, if necessary. I also added 2 decimals of precision to my angles.
• Added more operators to Rotation class
• Added all overrides to Rotation class (GetHashCode, Equals, and ToString)
• Created Point class
  • Has methods for Midpoint, Scaling, Angles from each other, Distance, and a handful of helpful operators
• Created Equation(2D) class
  • Defines a line
  • Can determine points along that line
  • Can determine an intersection point
• Created VectorObject
• Created LineObject
• Created Vector
• Standardized a lot of my methodology for randomized testing and ensuring I hit every method at least once.
• Testing is not complete; library has about 10 ...40 hours more of finishing touches.
• Many things planned in the future, but I want to get an update out. This adds a lot of nice touches and new classes, at least enough to be useful.

0.2.5 (12/7/24)

• Completed Rotation class
• DistanceTo, AverageTo, Cloning Constructor, IEquatable, and IComparable methods added
• Overrode operators + (addition), - (subtraction), % (modulo), and ^ (average of two angles)
• Ensured XML comments were included in the package
• Test cases up to 148

0.2.0 (12/6/24)

• Added Rotation class
