Method Descriptions¶

Vector3 Vector3 ( float x, float y, float z )

Returns a Vector3 with the given components.

Vector3 abs ( )

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

float angle_to ( Vector3 to )

Returns the minimum angle to the given vector.

Vector3 bounce ( Vector3 n )

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

Vector3 ceil ( )

Returns a new vector with all components rounded up.

Vector3 cross ( Vector3 b )

Returns the cross product with b.

Vector3 cubic_interpolate ( Vector3 b, Vector3 pre_a, Vector3 post_b, float t )

Performs a cubic interpolation between vectors pre_a, a, b, post_b (a is current), by the given amount t. t is in the range of 0.0 - 1.0, representing the amount of interpolation.

Vector3 direction_to ( Vector3 b )

Returns the normalized vector pointing from this vector to b.

float distance_squared_to ( Vector3 b )

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

float distance_to ( Vector3 b )

Returns the distance to b.

float dot ( Vector3 b )

Returns the dot product with b.

Vector3 floor ( )

Returns a new vector with all components rounded down.

Vector3 inverse ( )

Returns the inverse of the vector. This is the same as Vector3( 1.0 / v.x, 1.0 / v.y, 1.0 / v.z ).

bool is_equal_approx ( Vector3 v )

Returns true if this vector and v are approximately equal, by running @GDScript.is_equal_approx on each component.

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 function over length if you need to sort vectors or need the squared length for some formula.

Vector3 linear_interpolate ( Vector3 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..

int max_axis ( )

Returns the axis of the vector’s largest value. See AXIS_* constants.

int min_axis ( )

Returns the axis of the vector’s smallest value. See AXIS_* constants.

Vector3 move_toward ( Vector3 to, float delta )

Moves the vector toward to by the fixed delta amount.

Vector3 normalized ( )

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

Basis outer ( Vector3 b )

Returns the outer product with b.

Vector3 posmod ( float mod )

Returns a vector composed of the fposmod of this vector’s components and mod.

Vector3 posmodv ( Vector3 modv )

Returns a vector composed of the fposmod of this vector’s components and modv’s components.

Vector3 project ( Vector3 b )

Returns the vector projected onto the vector b.

Vector3 reflect ( Vector3 n )

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

Vector3 rotated ( Vector3 axis, float phi )

Rotates the vector around a given axis by phi radians. The axis must be a normalized vector.

Vector3 round ( )

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

Vector3 sign ( )

Returns the vector with each component set to one or negative one, depending on the signs of the components.

Vector3 slerp ( Vector3 b, float t )

Returns the result of spherical 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.

Note: Both vectors must be normalized.

Vector3 slide ( Vector3 n )

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

Vector3 snapped ( Vector3 by )

Returns a copy of the vector snapped to the lowest neared multiple.

Basis to_diagonal_matrix ( )

Returns a diagonal matrix with the vector as main diagonal.
