It uses floating-point coordinates. By default, these floating-point values use 32-bit precision, unlike [float] which is always 64-bit. If double precision is needed, compile the engine with the option [code]precision=double[/code].
[b]Note:[/b] In a boolean context, a Vector3 will evaluate to [code]false[/code] if it's equal to [code]Vector3(0, 0, 0)[/code]. Otherwise, a Vector3 will always evaluate to [code]true[/code].
Returns the derivative at the given [param t] on the [url=https://en.wikipedia.org/wiki/B%C3%A9zier_curve]Bézier curve[/url] defined by this vector and the given [param control_1], [param control_2], and [param end] points.
Returns the point at the given [param t] on the [url=https://en.wikipedia.org/wiki/B%C3%A9zier_curve]Bézier curve[/url] defined by this vector and the given [param control_1], [param control_2], and [param end] points.
Returns a new vector with all components clamped between the components of [param min] and [param max], by running [method @GlobalScope.clamp] on each component.
This returns a vector perpendicular to both this and [param with], which would be the normal vector of the plane defined by the two vectors. As there are two such vectors, in opposite directions, this method returns the vector defined by a right-handed coordinate system. If the two vectors are parallel this returns an empty vector, making it useful for testing if two vectors are parallel.
Performs a cubic interpolation between this vector and [param b] using [param pre_a] and [param post_b] as handles, and returns the result at position [param weight]. [param weight] is on the range of 0.0 to 1.0, representing the amount of interpolation.
Performs a cubic interpolation between this vector and [param b] using [param pre_a] and [param post_b] as handles, and returns the result at position [param weight]. [param weight] is on the range of 0.0 to 1.0, representing the amount of interpolation.
Returns the dot product of this vector and [param 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 [code]0[/code] for a right 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 [code]-1.0[/code] (180 degree angle) when the vectors are facing opposite directions, and [code]1.0[/code] (0 degree angle) when the vectors are aligned.
[b]Note:[/b] [code]a.dot(b)[/code] is equivalent to [code]b.dot(a)[/code].
Returns the result of the linear interpolation between this vector and [param to] by amount [param weight]. [param weight] is on the range of [code]0.0[/code] to [code]1.0[/code], representing the amount of interpolation.
Returns the result of scaling the vector to unit length. Equivalent to [code]v / v.length()[/code]. Returns [code](0, 0, 0)[/code] if [code]v.length() == 0[/code]. See also [method is_normalized].
Returns the octahedral-encoded (oct32) form of this [Vector3] as a [Vector2]. Since a [Vector2] occupies 1/3 less memory compared to [Vector3], this form of compression can be used to pass greater amounts of [method normalized] [Vector3]s without increasing storage or memory requirements. See also [method octahedron_decode].
[b]Note:[/b] [method octahedron_encode] can only be used for [method normalized] vectors. [method octahedron_encode] does [i]not[/i] check whether this [Vector3] is normalized, and will return a value that does not decompress to the original value if the [Vector3] is not normalized.
[b]Note:[/b] Octahedral compression is [i]lossy[/i], although visual differences are rarely perceptible in real world scenarios.
Returns a new vector resulting from projecting this vector onto the given vector [param b]. The resulting new vector is parallel to [param b]. See also [method slide].
[b]Note:[/b] If the vector [param b] is a zero vector, the components of the resulting new vector will be [constant @GDScript.NAN].
Returns the result of reflecting the vector through a plane defined by the given normal vector [param n].
[b]Note:[/b] [method reflect] differs from what other engines and frameworks call [code skip-lint]reflect()[/code]. In other engines, [code skip-lint]reflect()[/code] returns the result of the vector reflected by the given plane. The reflection thus passes through the given normal. While in Godot the reflection passes through the plane and can be thought of as bouncing off the normal. See also [method bounce] which does what most engines call [code skip-lint]reflect()[/code].
Returns the result of rotating this vector around a given axis by [param angle] (in radians). The axis must be a normalized vector. See also [method @GlobalScope.deg_to_rad].
Returns a new vector with each component set to [code]1.0[/code] if it's positive, [code]-1.0[/code] if it's negative, and [code]0.0[/code] if it's zero. The result is identical to calling [method @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 [param axis].
Returns the result of spherical linear interpolation between this vector and [param to], by amount [param weight]. [param 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 [method lerp].
Returns a new vector resulting from sliding this vector along a plane with normal [param n]. The resulting new vector is perpendicular to [param n], and is equivalent to this vector minus its projection on [param n]. See also [method project].
[b]Note:[/b] The vector [param n] must be normalized. See also [method normalized].
Returns a new vector with each component snapped to the nearest multiple of the corresponding component in [param step]. This can also be used to round the components to an arbitrary number of decimals.

Forward unit vector. Represents the local direction of forward, and the global direction of north. Keep in mind that the forward direction for lights, cameras, etc is different from 3D assets like characters, which face towards the camera by convention. Use [constant Vector3.MODEL_FRONT] and similar constants when working in 3D asset space.
[b]Note:[/b] Vectors with [constant @GDScript.NAN] elements don't behave the same as other vectors. Therefore, the results from this operator may not be accurate if NaNs are included.
Inversely transforms (multiplies) the [Vector3] by the given [Basis] matrix, under the assumption that the basis is orthonormal (i.e. rotation/reflection is fine, scaling/skew is not).
[code]vector * basis[/code] is equivalent to [code]basis.transposed() * vector[/code]. See [method Basis.transposed].
For transforming by inverse of a non-orthonormal basis (e.g. with scaling) [code]basis.inverse() * vector[/code] can be used instead. See [method Basis.inverse].
Inversely transforms (multiplies) the [Vector3] by the given [Transform3D] transformation matrix, under the assumption that the transformation basis is orthonormal (i.e. rotation/reflection is fine, scaling/skew is not).
[code]vector * transform[/code] is equivalent to [code]transform.inverse() * vector[/code]. See [method Transform3D.inverse].
For transforming by inverse of an affine transformation (e.g. with scaling) [code]transform.affine_inverse() * vector[/code] can be used instead. See [method Transform3D.affine_inverse].
Compares two [Vector3] vectors by first checking if the X value of the left vector is less than the X value of the [param 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 [param index]. [code]v[0][/code] is equivalent to [code]v.x[/code], [code]v[1][/code] is equivalent to [code]v.y[/code], and [code]v[2][/code] is equivalent to [code]v.z[/code].
Returns the negative value of the [Vector3]. This is the same as writing [code]Vector3(-v.x, -v.y, -v.z)[/code]. This operation flips the direction of the vector while keeping the same magnitude. With floats, the number zero can be either positive or negative.
