Vector3¶
Vector used for 3D math using floating point coordinates.
Description¶
3-element structure that can be used to represent positions in 3D space or any other triplet of numeric values.
It uses floating-point coordinates. See Vector3i for its integer counterpart.
Note: In a boolean context, a Vector3 will evaluate to false if it's equal to Vector3(0, 0, 0). Otherwise, a Vector3 will always evaluate to true.

Constructor Descriptions¶
Vector3 Vector3 ( )
Constructs a default-initialized Vector3 with all components set to 0.
Constructs a Vector3 as a copy of the given Vector3.
Constructs a new Vector3 from Vector3i.
Returns a Vector3 with the given components.
Method Descriptions¶
Vector3 abs ( ) const
Returns a new vector with all components in absolute values (i.e. positive).
Returns the unsigned minimum angle to the given vector, in radians.
Returns the point at the given t on the Bezier curve defined by this vector and the given control_1, control_2, and end points.
Returns the vector "bounced off" from a plane defined by the given normal.
Vector3 ceil ( ) const
Returns a new vector with all components rounded up (towards positive infinity).
Returns a new vector with all components clamped between the components of min and max, by running @GlobalScope.clamp on each component.
Returns the cross product of this vector and with.
Performs a cubic interpolation between this vector and b using pre_a and post_b as handles, and returns the result at position weight. weight is on the range of 0.0 to 1.0, representing the amount of interpolation.
Vector3 cubic_interpolate_in_time ( Vector3 b, Vector3 pre_a, Vector3 post_b, float weight, float b_t, float pre_a_t, float post_b_t ) const
Performs a cubic interpolation between this vector and b using pre_a and post_b as handles, and returns the result at position weight. weight is on the range of 0.0 to 1.0, representing the amount of interpolation.
It can perform smoother interpolation than cubic_interpolate() by the time values.
Returns the normalized vector pointing from this vector to to. This is equivalent to using (b - a).normalized().
Returns the squared distance between this vector and to.
This method runs faster than distance_to, so prefer it if you need to compare vectors or need the squared distance for some formula.
Returns the distance between this vector and to.
Returns the dot product of this vector and with. This can be used to compare the angle between two vectors. For example, this can be used to determine whether an enemy is facing the player.
The dot product will be 0 for a straight angle (90 degrees), greater than 0 for angles narrower than 90 degrees and lower than 0 for angles wider than 90 degrees.
When using unit (normalized) vectors, the result will always be between -1.0 (180 degree angle) when the vectors are facing opposite directions, and 1.0 (0 degree angle) when the vectors are aligned.
Note: a.dot(b) is equivalent to b.dot(a).
Vector3 floor ( ) const
Returns a new vector with all components rounded down (towards negative infinity).
Vector3 inverse ( ) const
Returns the inverse of the vector. This is the same as Vector3(1.0 / v.x, 1.0 / v.y, 1.0 / v.z).
Returns true if this vector and to are approximately equal, by running @GlobalScope.is_equal_approx on each component.
bool is_normalized ( ) const
Returns true if the vector is normalized, false otherwise.
bool is_zero_approx ( ) const
Returns true if this vector's values are approximately zero, by running @GlobalScope.is_zero_approx on each component.
This method is faster than using is_equal_approx with one value as a zero vector.
float length ( ) const
Returns the length (magnitude) of this vector.
float length_squared ( ) const
Returns the squared length (squared magnitude) of this vector.
This method runs faster than length, so prefer it if you need to compare vectors or need the squared distance for some formula.
Returns the result of the linear interpolation between this vector and to by amount weight. weight is on the range of 0.0 to 1.0, representing the amount of interpolation.
Returns the vector with a maximum length by limiting its length to length.
int max_axis_index ( ) const
Returns the axis of the vector's highest value. See AXIS_* constants. If all components are equal, this method returns AXIS_X.
int min_axis_index ( ) const
Returns the axis of the vector's lowest value. See AXIS_* constants. If all components are equal, this method returns AXIS_Z.
Returns a new vector moved toward to by the fixed delta amount. Will not go past the final value.
Vector3 normalized ( ) const
Returns the vector scaled to unit length. Equivalent to v / v.length().
Vector2 octahedron_encode ( ) const

Returns this vector projected onto the vector b.
Returns this vector reflected from a plane defined by the given normal.
Rotates this vector around a given axis by angle (in radians). The axis must be a normalized vector.
Vector3 round ( ) const
Returns a new vector with all components rounded to the nearest integer, with halfway cases rounded away from zero.
Vector3 sign ( ) const
Returns a new vector with each component set to one or negative one, depending on the signs of the components, or zero if the component is zero, by calling @GlobalScope.sign on each component.
Returns the signed angle to the given vector, in radians. The sign of the angle is positive in a counter-clockwise direction and negative in a clockwise direction when viewed from the side specified by the axis.
Returns the result of spherical linear interpolation between this vector and to, by amount weight. weight is on the range of 0.0 to 1.0, representing the amount of interpolation.
This method also handles interpolating the lengths if the input vectors have different lengths. For the special case of one or both input vectors having zero length, this method behaves like lerp.
Returns this vector slid along a plane defined by the given normal.
Returns this vector with each component snapped to the nearest multiple of step. This can also be used to round to an arbitrary number of decimals.

Compares two Vector3 vectors by first checking if the X value of the left vector is less than the X value of the right vector. If the X values are exactly equal, then it repeats this check with the Y values of the two vectors, and then with the Z values. This operator is useful for sorting vectors.

Access vector components using their index. v[0] is equivalent to v.x, v[1] is equivalent to v.y, and v[2] is equivalent to v.z.
Vector3 operator unary+ ( )
Returns the same value as if the + was not there. Unary + does nothing, but sometimes it can make your code more readable.
Vector3 operator unary- ( )
Returns the negative value of the Vector3. This is the same as writing Vector3(-v.x, -v.y, -v.z). This operation flips the direction of the vector while keeping the same magnitude. With floats, the number zero can be either positive or negative.
