Method Descriptions

Vector2 Vector2 ( float x, float y )

Constructs a new Vector2 from the given x and y.

Vector2 abs ( )

Returns a new vector with all components in absolute values (i.e. positive).

float angle ( )

Returns the vector’s angle in radians with respect to the x-axis, or (1, 0) vector.

Equivalent to the result of atan2 when called with the vector’s x and y as parameters: atan2(x, y).

float angle_to ( Vector2 to )

Returns the angle in radians between the two vectors.

float angle_to_point ( Vector2 to )

Returns the angle in radians between the line connecting the two points and the x coordinate.

float aspect ( )

Returns the ratio of x to y.

Vector2 bounce ( Vector2 n )

Returns the vector “bounced off” from a plane defined by the given normal.

Vector2 ceil ( )

Returns the vector with all components rounded up.

Vector2 clamped ( float length )

Returns the vector with a maximum length.

float cross ( Vector2 with )

Returns the 2 dimensional analog of the cross product with the given vector.

Vector2 cubic_interpolate ( Vector2 b, Vector2 pre_a, Vector2 post_b, float t )

Cubicly interpolates between this vector and b using pre_a and post_b as handles, and returns the result at position t. t is in the range of 0.0 - 1.0, representing the amount of interpolation.

Vector2 direction_to ( Vector2 b )

Returns the normalized vector pointing from this vector to b.

float distance_squared_to ( Vector2 to )

Returns the squared distance to vector b. Prefer this function over distance_to if you need to sort vectors or need the squared distance for some formula.

float distance_to ( Vector2 to )

Returns the distance to vector b.

float dot ( Vector2 with )

Returns the dot product with vector b.

Vector2 floor ( )

Returns the vector with all components rounded down.

bool is_normalized ( )

Returns true if the vector is normalized.

float length ( )

Returns the vector’s length.

float length_squared ( )

Returns the vector’s length squared. Prefer this method over length if you need to sort vectors or need the squared length for some formula.

Vector2 linear_interpolate ( Vector2 b, float t )

Returns the result of the linear interpolation between this vector and b by amount t. t is in the range of 0.0 - 1.0, representing the amount of interpolation.

Vector2 normalized ( )

Returns the vector scaled to unit length. Equivalent to v / v.length().

Vector2 project ( Vector2 b )

Returns the vector projected onto the vector b.

Vector2 reflect ( Vector2 n )

Returns the vector reflected from a plane defined by the given normal.

Vector2 rotated ( float phi )

Returns the vector rotated by phi radians. See also @GDScript.deg2rad.

Vector2 round ( )

Returns the vector with all components rounded to the nearest integer, with halfway cases rounded away from zero.

Vector2 slerp ( Vector2 b, float t )

Returns the result of SLERP between this vector and b, by amount t. t is in the range of 0.0 - 1.0, representing the amount of interpolation.

Both vectors need to be normalized.

Vector2 slide ( Vector2 n )

Returns the component of the vector along a plane defined by the given normal.

Vector2 snapped ( Vector2 by )

Returns the vector snapped to a grid with the given size.

Vector2 tangent ( )

Returns a perpendicular vector.
