<brief_description>
|
|
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].
