<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 triplet of numeric values.
|
|
It uses integer coordinates and is therefore preferable to [Vector3] when exact precision is required. Note that the values are limited to 32 bits, and unlike [Vector3] this cannot be configured with an engine build option. Use [int] or [PackedInt64Array] if 64-bit values are needed.
|
|
[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].

|
|
Constructs a new [Vector3i] from the given [Vector3] by truncating components' fractional parts (rounding towards zero). For a different behavior consider passing the result of [method Vector3.ceil], [method Vector3.floor] or [method Vector3.round] to this constructor instead.

<return type="int" />
|
|
<description>
|
|

|
This method runs faster than [method length], so prefer it if you need to compare vectors or need the squared distance for some formula.

|
<description>
|
|
Returns a new vector with each component set to [code]1[/code] if it's positive, [code]-1[/code] if it's negative, and [code]0[/code] if it's zero. The result is identical to calling [method @GlobalScope.sign] on each component.

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.

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.
