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.

|

Compares two [Vector4] vectors by first checking if the X value of the left vector is greater 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, Z values of the two vectors, and then with the W values. This operator is useful for sorting vectors.

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 [Vector4]. This is the same as writing [code]Vector4(-v.x, -v.y, -v.z, -v.w)[/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.
