MuffinMaths

public static rad2deg(angle: number): number

Converts an angle in radians to degrees.

public static deg2rad(angle: number): number

Converts an angle in degrees to radians.

public static clamp(value: number, min: number, max: number): number

Clamps a value between given min (inclusive) and max (inclusive).

• value: number: he value to clamp
• min: number: Minimum value (inclusive)
• max: number: Maximum value (inclusive)

public static random(min: number, max: number): number

Gets a random value between given min (inclusive) and max (inclusive).

• min: number: Minimum random value (inclusive)
• max: number: Maximum random value (inclusive)

public static randomInteger(min: number, max: number): number

Gets a random integer number between given min (inclusive) and max (exclusive).

• min: number: Minimum random value (inclusive)
• max: number: Maximum random value (exclusive)

Vector2D

Constructor

constructor(public x = 0, public y = 0) { }

• x: number
• y: number

Instance Methods

public toString(): string

Converts the vector into a string.

public normalize(): void

Normalizes this vector in-place (it overrides its properties).

public get normalized(): Vector2D

Gets a copy of this vector, but normalized (it doesn't override the properties of the current vector).

public get magnitudeSqr(): number

Gets the squared magnitude (or length) of this vector.

public get magnitude(): number

Gets the magnitude (or length) of this vector.

Static Methods

public static angle(v1: Vector2D, v2: Vector2D): number 

Calculates the angle between the given vectors.

public static angleDeg(v1: Vector2D, v2: Vector2D): number

Calculates the angle between the given vectors, then convert that value in degrees.

public static dot(v1: Vector2D, v2: Vector2D): number

Calculates the dot product between the two given vectors.

public static fromObject(obj: any): Vector2D

Makes a new Vector instance, using x and y properties of the given object. Note that if x or y property doesn't exist or is null, its value is 0.

public static add(v1: Vector2D, v2: Vector2D): Vector2D

Makes an addition between the two given vectors.

public static substract(v1: Vector2D, v2: Vector2D): Vector2D

Makes a substraction between the two given vectors.
