画布组 (Canvas Group) 可集中控制整组 UI 元素的某些方面,而无需单独处理每个元素。画布组的属性会影响所在的游戏对象以及所有子对象。
属性: | 功能: |
---|---|
Alpha | 此组中的 UI 元素的不透明度。该值介于 0 和 1 之间,其中 0 表示完全透明,1 表示完全不透明。请注意,UI 元素也会保留自己的透明度,因此画布组的 Alpha 值将与各个元素的 Alpha 值彼此相乘。 |
Interactable | 确定此组件是否接受输入。当设置为 false 时,禁用交互。 |
Block Raycasts | 此组件是否作为射线投射的碰撞体?需要在连接到画布的图形射线投射器上调用 RayCast 函数。这_不_适用于 Physics.Raycast。 |
Ignore Parent Groups | 此组还会受到游戏对象层级视图中更上层的画布组 (Canvas Group) 组件中的设置所影响,还是会忽略并因此覆盖这些设置? |
