<brief_description>
|
|
A 4D vector using floating point coordinates.
|
|
</brief_description>
|
|
<description>
|
|
A 4-element structure that can be used to represent 4D coordinates or any other quadruplet 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 [code]precision=double[/code].
|
|
See [Vector4i] for its integer counterpart.
|
|
[b]Note:[/b] In a boolean context, a Vector4 will evaluate to [code]false[/code] if it's equal to [code]Vector4(0, 0, 0, 0)[/code]. Otherwise, a Vector4 will always evaluate to [code]true[/code].

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], [code]v[2][/code] is equivalent to [code]v.z[/code], and [code]v[3][/code] is equivalent to [code]v.w[/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.
