Vector used for 2D math using floating point coordinates. 2-element structure that can be used to represent positions in 2D space or any other pair of numeric values. It uses floating-point coordinates. See [Vector2i] for its integer counterpart. [b]Note:[/b] In a boolean context, a Vector2 will evaluate to [code]false[/code] if it's equal to [code]Vector2(0, 0)[/code]. Otherwise, a Vector2 will always evaluate to [code]true[/code]. $DOCS_URL/tutorials/math/index.html $DOCS_URL/tutorials/math/vector_math.html $DOCS_URL/tutorials/math/vectors_advanced.html https://www.youtube.com/playlist?list=PLZHQObOWTQDPD3MizzM2xVFitgF8hE_ab https://godotengine.org/asset-library/asset/584 https://github.com/godotengine/godot-demo-projects/tree/master/2d Constructs a default-initialized [Vector2] with all components set to [code]0[/code]. Constructs a [Vector2] as a copy of the given [Vector2]. Constructs a new [Vector2] from [Vector2i]. Constructs a new [Vector2] from the given [param x] and [param y]. Returns a new vector with all components in absolute values (i.e. positive). Returns this vector's angle with respect to the positive X axis, or [code](1, 0)[/code] vector, in radians. For example, [code]Vector2.RIGHT.angle()[/code] will return zero, [code]Vector2.DOWN.angle()[/code] will return [code]PI / 2[/code] (a quarter turn, or 90 degrees), and [code]Vector2(1, -1).angle()[/code] will return [code]-PI / 4[/code] (a negative eighth turn, or -45 degrees).

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. Returns the 2D analog of the cross product for this vector and [param 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. [b]Note:[/b] 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. Cubically interpolates 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 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 [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 a new vector with all components rounded down (towards negative infinity).

[codeblock] 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).

Returns [code]true[/code] if the vector is normalized, [code]false[/code] otherwise. Returns [code]true[/code] if this vector's values are approximately zero, by running [method @GlobalScope.is_zero_approx] on each component. This method is faster than using [method is_equal_approx] with one value as a zero vector. Returns the length (magnitude) of this vector. Returns the squared length (squared magnitude) of this vector. This method runs faster than [method 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 [param to] by amount [param weight]. [param 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 [param length]. Returns the axis of the vector's highest value. See [code]AXIS_*[/code] constants. If all components are equal, this method returns [constant AXIS_X]. Returns the axis of the vector's lowest value. See [code]AXIS_*[/code] constants. If all components are equal, this method returns [constant AXIS_Y]. Returns a new vector moved toward [param to] by the fixed [param delta] amount. Will not go past the final value.

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 this vector slid along a plane defined by the given normal. Returns this vector with each component snapped to the nearest multiple of [param step]. This can also be used to round to an arbitrary number of decimals. The vector's X component.
