<brief_description>
|
|
Vector used for 2D math using integer coordinates.
|
|
</brief_description>
|
|
<description>
|
|
2-element structure that can be used to represent positions in 2D space or any other pair of numeric values.
|
|
It uses integer coordinates and is therefore preferable to [Vector2] when exact precision is required.
|
|
[b]Note:[/b] In a boolean context, a Vector2i will evaluate to [code]false[/code] if it's equal to [code]Vector2i(0, 0)[/code]. Otherwise, a Vector2i will always evaluate to [code]true[/code].
