A 2D vector using floating point coordinates.

A 2-element structure that can be used to represent 2D coordinates or any other pair of numeric values.

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 precision=double.

See Vector2i for its integer counterpart.

 Vector2 Vector2<>():Vector2

Constructs a default-initialized Vector2 with all components set to 0.

 Vector2 Vector2<>( Vector2 from=, from:Vector2=, ):Vector2

Constructs a Vector2 as a copy of the given Vector2.

 Vector2 Vector2<>( Vector2i from=, from:Vector2i=, ):Vector2

Constructs a new Vector2 from Vector2i.

 Vector2 Vector2<>( float x=, x:float=, float y=, y:float=, ):Vector2

Constructs a new Vector2 from the given x and y.

 bool operator !=<>( Vector2 right=, right:Vector2=, ):bool

Returns true if the vectors are not equal.

Note: Due to floating-point precision errors, consider using is_equal_approx instead, which is more reliable.

Note: Vectors with @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.

 Vector2 operator *<>( Transform2D right=, right:Transform2D=, ):Vector2

Inversely transforms (multiplies) the Vector2 by the given Transform2D transformation matrix, under the assumption that the transformation basis is orthonormal (i.e. rotation/reflection is fine, scaling/skew is not).

vector * transform is equivalent to transform.inverse() * vector. See Transform2D.inverse.

For transforming by inverse of an affine transformation (e.g. with scaling) transform.affine_inverse() * vector can be used instead. See Transform2D.affine_inverse.

 Vector2 operator *<>( Vector2 right=, right:Vector2=, ):Vector2

Multiplies each component of the Vector2 by the components of the given Vector2.
print(Vector2(10, 20) * Vector2(3, 4)) # Prints "(30, 80)"
Vector2 operator *<>( float right=, right:float=, ):Vector2

Multiplies each component of the Vector2 by the given float.

 bool operator <<>( Vector2 right=, right:Vector2=, ):bool

Compares two Vector2 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. This operator is useful for sorting vectors.

Note: Vectors with @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.

 bool operator <=<>( Vector2 right=, right:Vector2=, ):bool

 bool operator ==<>( Vector2 right=, right:Vector2=, ):bool

Returns true if the vectors are exactly equal.

Note: Due to floating-point precision errors, consider using is_equal_approx instead, which is more reliable.

Note: Vectors with @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.

 bool operator ><>( Vector2 right=, right:Vector2=, ):bool

Access vector components using their index. v[0] is equivalent to v.x, and v[1] is equivalent to v.y.

 Vector2 operator unary+<>():Vector2

Returns the same value as if the + was not there. Unary + does nothing, but sometimes it can make your code more readable.

 Vector2 operator unary-<>():Vector2

Returns the negative value of the Vector2. This is the same as writing Vector2(-v.x, -v.y). This operation flips the direction of the vector while keeping the same magnitude. With floats, the number zero can be either positive or negative.

Returns this vector's angle with respect to the positive X axis, or (1, 0) vector, in radians.

For example, Vector2.RIGHT.angle() will return zero, Vector2.DOWN.angle() will return PI / 2 (a quarter turn, or 90 degrees), and Vector2(1, -1).angle() will return -PI / 4 (a negative eighth turn, or -45 degrees).

Illustration of the returned angle.

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

 float cross<>( Vector2 with=, with:Vector2=, ):float

Returns the 2D analog of the cross product for this vector and with.

This is the signed area of the parallelogram formed by the two vectors. If the second vector is clockwise from the first vector, then the cross product is the positive area. If counter-clockwise, the cross product is the negative area.

Note: Cross product is not defined in 2D mathematically. This method embeds the 2D vectors in the XY plane of 3D space and uses their cross product's Z component as the analog.

 Vector2 cubic_interpolate<>( Vector2 b=, b:Vector2=, Vector2 pre_a=, pre_a:Vector2=, Vector2 post_b=, post_b:Vector2=, float weight=, weight:float=, ):Vector2

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.

 Vector2 cubic_interpolate_in_time<>( Vector2 b=, b:Vector2=, Vector2 pre_a=, pre_a:Vector2=, Vector2 post_b=, post_b:Vector2=, float weight=, weight:float=, float b_t=, b_t:float=, float pre_a_t=, pre_a_t:float=, float post_b_t=, post_b_t:float=, ):Vector2

Returns the normalized vector pointing from this vector to to. This is equivalent to using (b - a).normalized().

 float distance_squared_to<>( Vector2 to=, to:Vector2=, ):float

This method runs faster than distance_to, so prefer it if you need to compare vectors or need the squared distance for some formula.

 float distance_to<>( Vector2 to=, to:Vector2=, ):float

Returns the distance between this vector and to.

 float dot<>( Vector2 with=, with:Vector2=, ):float

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).

 Vector2 floor<>():Vector2

Returns a new vector with all components rounded down (towards negative infinity).

 Vector2 from_angle<>( float angle=, angle:float=, ):Vector2

Creates a unit Vector2 rotated to the given angle in radians. This is equivalent to doing Vector2(cos(angle), sin(angle)) or Vector2.RIGHT.rotated(angle).
print(Vector2.from_angle(0)) # Prints (1, 0). print(Vector2(1, 0).angle()) # Prints 0, which is the angle used above. print(Vector2.from_angle(PI / 2)) # Prints (0, 1).

This method is faster than using is_equal_approx with one value as a zero vector.

 float length<>():float

Returns the length (magnitude) of this vector.

 float length_squared<>():float

 Vector2 sign<>():Vector2

Returns a new vector with each component set to 1.0 if it's positive, -1.0 if it's negative, and 0.0 if it's zero. The result is identical to calling @GlobalScope.sign on each component.
