<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. Note that the values are limited to 32 bits, and unlike [Vector2] 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 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].

Constructs a new [Vector2i] from the given [Vector2] by truncating components' fractional parts (rounding towards zero). For a different behavior consider passing the result of [method Vector2.ceil], [method Vector2.floor] or [method Vector2.round] to this constructor instead.

|
|
<description>
|
|
Returns a new vector with all components in absolute values (i.e. positive).
|

<return type="int" />
|
|
<description>
|
|
Returns the squared length (squared magnitude) of this vector.

|
|
<method name="max_axis_index" qualifiers="const">
|
|

|
<method name="min_axis_index" qualifiers="const">
|
|
<return type="int" />

<description>
|
|

Gets the remainder of each component of the [Vector2i] with the components of the given [Vector2i]. 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.
