ParallaxLayer
|
||
=============
|
||
|
||
**继承：** :ref:`Node2D<class_Node2D>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`
|
||
|
||
使用 :ref:`ParallaxBackground<class_ParallaxBackground>` 的视差滚动层。

描述
|
||
----
|
||
|
||
ParallaxLayer 必须是 :ref:`ParallaxBackground<class_ParallaxBackground>` 节点的子节点。每个 ParallaxLayer 都可以设置为相对于相机移动或 :ref:`ParallaxBackground.scroll_offset<class_ParallaxBackground_property_scroll_offset>` 值。
|
||
|
||
该节点的子节点将受其滚动偏移量的影响。
|
||
|
||
\ **注意：**\ 当该节点进入场景后，对其位置和比例的任何改变都将被忽略。

|
||
|
||
**ParallaxLayer** 重复绘制的间隔，单位为像素。用于创建无限滚动的背景。如果将某个轴设置为 ``0``\ ，那么 **ParallaxLayer** 就只会在那个方向上绘制一次。
|
||
|
||
\ **注意：**\ 如果想要在重复时让子节点显示的 :ref:`Texture2D<class_Texture2D>` 进行像素级对齐，那么就应当在设置间隔时考虑纹理所使用的缩放。例如你使用 :ref:`Sprite2D<class_Sprite2D>` 节点将 600×600 的纹理进行 ``0.5`` 的缩放，然后希望纹理横向重复，那么就应该将“Mirroring”设置为 ``Vector2(300, 0)``\ 。
|
||
|
||
\ **注意：**\ 如果视口的某个轴比对应重复轴的两倍还要大，那么就无法无限重复，因为时差图层同一时间只能将该图层绘制两份。计算可见窗口时依据的是父级 :ref:`ParallaxBackground<class_ParallaxBackground>` 的位置，而不是图层自身的位置。因此，使用镜像时，\ **请勿**\ 改变 **ParallaxLayer** 相对于父节点的位置。如果需要修改背景的位置，请改为设置 :ref:`ParallaxBackground<class_ParallaxBackground>` 父节点的 :ref:`CanvasLayer.offset<class_CanvasLayer_property_offset>` 属性。
|
||
|
||
\ **注意：**\ 虽然这个属性的名叫 Mirroring，是“镜像”的意思，但是并不会对图层做镜像，只会进行重复。
