Parameters


dot

public dotpossibleVector: PossibleVector2number: number

Parameters


equals

public equalsother: Vector2threshold: number = EPSILON: boolean

Check if two vectors are equal to each other.

This method allows passing an allowed error margin when comparing vectors to compensate for floating point inaccuracies. To check if two vectors are exactly equal, use the exactlyEquals method, instead.

Parameters

  • other: Vector2

    The vector to compare.

  • threshold: number = EPSILON

    The allowed error threshold when comparing the vectors.


exactlyEquals

public exactlyEqualsother: Vector2: boolean

Check if two vectors are exactly equal to each other.

If you need to compensate for floating point inaccuracies, use the equals method, instead.

polarLerp

static public polarLerpfrom: Vector2to: Vector2value: numbercounterclockwise: boolean = falseorigin: Vector2 = Vector2.zero: Vector2

Interpolates between two vectors on the polar plane by interpolating the angles and magnitudes of the vectors individually.

This function is useful when used in conjunction with rotate to animate an object's position on a circular arc (see examples).

Examples

Parameters

  • from: Vector2

    The starting vector.

  • to: Vector2

    The target vector.

  • value: number

    The t-value of the interpolation.

  • counterclockwise: boolean = false

    Whether the vector should get rotated counterclockwise. Defaults to false.

  • origin: Vector2 = Vector2.zero

    The center of rotation. Defaults to the origin.


radians

static public radiansx: numbery: number: number

Return the angle in radians between the vector described by x and y and the positive x-axis.

Parameters

  • x: number

    The x component of the vector.

  • y: number

    The y component of the vector.


squaredMagnitude
