Triangle2D

[wbm1113]

What?

Triangle2D class with extensions for Vector2 that it relies on (to rotate a 2D vector about an arbitrary origin)

Why?

Checking 2D triangle collision in Unity typically requires a polygon collider. For example, if you want to detect an object with an entity's field of view. This is performance inefficient. Using this class lets you run that kind of collision detection without actually using any colliders.

How?

Basic arithmetic
