Methods

add(v: Vector2, w?: Vector2): this

Adds v to this vector.

addScalar(s: number): this

Adds the scalar value s to this vector's x and y values.

addScaledVector(v: Vector2, s: number): this

Adds the multiple of v and s to this vector.

addVectors(a: Vector2, b: Vector2): this

Sets this vector to a + b.

angle(): number

computes the angle in radians with respect to the positive x-axis

applyMatrix3(m: Matrix3): this

Multiplies this vector (with an implicit 1 as the 3rd component) by m.

ceil(): this

The x and y components of the vector are rounded up to the nearest integer value.

clamp(min: Vector2, max: Vector2): this

If this vector's x or y value is greater than the max vector's x or y value, it is replaced by the corresponding value. If this vector's x or y value is less than the min vector's x or y value, it is replaced by the corresponding value.

clampLength(min: number, max: number): this

If this vector's length is greater than the max value, it is replaced by the max value. If this vector's length is less than the min value, it is replaced by the min value.

clampScalar(min: number, max: number): this

If this vector's x or y values are greater than the max value, they are replaced by the max value. If this vector's x or y values are less than the min value, they are replaced by the min value.

clone(): this

Returns a new Vector2 instance with the same x and y values.

copy(v: Vector2): this

Copies value of v to this vector.
