<brief_description>
|
|
Vector used for 3D math using integer 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 integer coordinates and is therefore preferable to [Vector3] when exact precision is required.
|
|
[b]Note:[/b] In a boolean context, a Vector3i will evaluate to [code]false[/code] if it's equal to [code]Vector3i(0, 0, 0)[/code]. Otherwise, a Vector3i will always evaluate to [code]true[/code].

Gets the remainder of each component of the [Vector3i] with the components of the given [Vector3i]. This operation uses truncated division, which is often not desired as it does not work well with negative numbers. Consider using [method @GlobalScope.posmod] instead if you want to handle negative numbers.

Compares two [Vector3i] 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.
