Class Vector2

Get the direction as an unit vector

Get the magnitude of the vector

Colne a vector into a new instace

Copy the target vector properties

Get the distance with another vector

Compare if two vector are equals

Set the vector

Calculates a + b

Example

const v1 = new Vector2(2, 1);
const v2 = new Vector2(3, 2);
const v3 = Vector2.add(new Vector2(), v1, v2);
v3.x // 5
v3.y // 3
Copy

Calculates the cross product of two vectors and returns a scalar value

Example

const v1 = new Vector2(3, 2);
const v2 = new Vector2(2, 1);
Vector2.cross(v1, v2); // -1
Copy

Calculates the dot product of two vectors and returns a scalar value

Example

const v1 = new Vector2(3, 2);
const v2 = new Vector2(2, 1);
Vector2.dot(v1, v2); // 8
Copy

Normalize a vector

Example

const v1 = new Vector2(0, 2);
const v2 = Vector2.normal(new Vector2(), v1);
v2.x // -2
v2.y // 0
Copy

Rounds a vector

Example

const v1 = new Vector2(3.9, 2.2);
const v2 = Vector2.round(new Vector2(), v1);
v2.x // 4
v2.y // 2
Copy

Scale a vector

Example

const v1 = new Vector2(3, 2);
const v2 = Vector2.scale(new Vector2(), v1, 2);
v2.x // 6
v2.y // 4
Copy

Calculates a - b

Example

const v1 = new Vector2(3, 2);
const v2 = new Vector2(2, 1);
const v3 = Vector2.subtract(new Vector2(), v1, v2);
v3.x // 1
v3.y // 1
Copy

Returns the unit vector

Example

const v1 = new Vector2(3, 0);
const v2 = Vector2.unit(new Vector2(), v1);
v2.x // 1
v2.y // 0
Copy
