|
Vector used for 3D math using floating point coordinates.
|
|
</brief_description>
|
|
<description>
|
|
3-element structure that can be used to represent positions in 3D space or any other pair of numeric values.
|
|
It uses floating-point coordinates. See [Vector3i] for its integer counterpart.
|
|
[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].

Compares two [Vector3] vectors by first checking if the X value of the left vector is less than the X value of the [code]right[/code] 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.

Compares two [Vector3] vectors by first checking if the X value of the left vector is less than or equal to the X value of the [code]right[/code] 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.

Returns [code]true[/code] if the vectors are exactly equal.

[b]Note:[/b] Due to floating-point precision errors, consider using [method is_equal_approx] instead, which is more reliable.

Access vector components using their 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 same value as if the [code]+[/code] was not there. Unary [code]+[/code] does nothing, but sometimes it can make your code more readable.

|
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.
