Vector4
|
||
=======
|
||
|
||
A 4D vector using floating-point coordinates.
|

|
||
說明
|
||
----
|
||
|
||
包含四個元素的結構體，可用於代表 4D 座標或任何數值的四元組。
|
||
|
||
使用浮點數座標。預設情況下，這些浮點值為 32 位精度，與始終為 64 位的 :ref:`float<class_float>` 並不相同。如果需要雙精度，請在編譯引擎時使用 ``precision=double`` 選項。
|
||
|
||
對應的整數版本見 :ref:`Vector4i<class_Vector4i>`\ 。
|
||
|
||
\ **注意：**\ 在布林語境中，如果 Vector4 等於 ``Vector4(0, 0, 0, 0)`` 則求值結果為 ``false``\ 。否則 Vector4 的求值結果始終為 ``true``\ 。
