What's Included

$3

- Vec2, Vec3, Vec4, Mat2, Mat3, and Mat4 classes
- Dot products, cross products, vector-matrix multiplication, transformation matrices, and more

$3

- Random class
- Uses xorShift32 as default random function
- float(n) - returns a random float between 0, n) (exclusive)
- chance(n, max) - returns true or false based off of n in max chances (ex: chance(1, 5) would return true 20% of the time)
- int(n) - returns a random int between [0, n) (exclusive) (ex: int(3) would return 0, 1, or 2)
- range(a, b) - returns a random float between [a, b) (exclusive)
- bool() - returns true or false
- sign() - returns -1 or 1
- angle() - returns a random angle in degrees [0, 360)
- choose(...items) - returns a random item from the items passed (ex: choose(1, 2, 3) would return 1, 2, or 3)
- shuffle(arr) - shuffles an array using the Fisher–Yates shuffle algorithm
- vec2(scale) - returns a random Vec2 of the length of scale (defaults to 1)
- vec3(scale) - returns a random Vec3 of the length of scale (defaults to 1`)
