The Vector2 data type represents a 2D value with direction and magnitude. Some applications include GUI elements and 2D mouse positions.

Math Operations

The following math operations are valid for the Vector2 data type:

OperationDescription
Vector2 + Vector2Produces a Vector2 with each component of the second added to the corresponding component of the first.
Vector2 - Vector2Produces a Vector2 with each component of the second subtracted from the corresponding component of the first.
Vector2 * Vector2Produces a Vector2 with each component of the second multiplied by the corresponding component of the first.
Vector2 / Vector2Produces a Vector2 with each component of the first divided by the corresponding component of the second.
Vector2 * numberProduces a Vector2 with each component multiplied by the number.
Vector2 / numberProduces a Vector2 with each component divided by the number.

Angle

number

Returns the angle in radians between the two vectors. Specify true for the optional isSigned boolean if you want a signed angle. By default, the method returns the absolute value. Signed angles are a negative when going clockwise. Values are in the range [0, pi] for absolute angles and [-pi, pi] for signed angles.
