Making one or more UI elements not block mouse events by placing a Canvas Group component on the element or one of its parents and setting its Block Raycasts property to false. 使一个或多个UI元素不会阻塞鼠标事件,方法是在元素或其父元素之一上放置Canvas Group组件,并将其“Block Raycasts”属性设...
CanvasGroup GameObject, the parent Canvas does not render any of its child GameObjects, including the CanvasGroup you want to render. To get the child CanvasGroup GameObject, do one of two things: In the parent Canvas, set the CanvasGroup component's alpha to a small, non-zero value. ...
Canvas Group is a component that allows you to control the visibility, interactability, and alpha transparency of UI elements within a Canvas. It provides a way to easily manage the properties of multiple UI elements together.Typical uses of Canvas Group:...
这是一个需要通过Add Component添加的组件,可以发现这个组件上也有一个Alpha选项,Canvas Group也是一个控制对象不透明度属性的组件,但是Image组件里的Alpha只能控制Image组件所在的节点(对象)的不透明度,也就是只能控制单一节点的不透明度。而Canvas Group可以控制这个组件所在的节点,以及这个节点下所有子节点的不透明度属性...
二、在脚本中使用AddComponent函数添加一个组件,例如: using UnityEngine; using System.Collections; public class Test : MonoBehaviour { private CanvasGroup m_CanvasGroup; void Start() { m_CanvasGroup = GetComponent<CanvasGroup> (); if(m_CanvasGroup == null){ ...
②在其Inspector窗口中,点击Add Component,搜索Canvas Group,选择添加Canvas Group组件。 ③在Canvas Group组件中,把Alpha数值设置为0,此时我们可以看到图片变为全透明。 ④接下来我们点击Scene视窗左上的2D按钮,转换回3D模式。并且左键双击Hierarchy中的JohnLemon,快速定位到JohnLemon。
4. Canvas Group的使用 添加方式:Add Component -> Canvas Group 画布组的核心作用就是同时更改其所有子物体的某些属性。 属性介绍(字面意思很清楚): (1)第一个是控制子物体的透明度。 (2)第二个是控制子物体的点击交互事件是否有效。 (3)第三个是控制子物体的射线检测是否接受。
var image = m_DraggingIcon.AddComponent (); CanvasGroup group = m_DraggingIcon.AddComponent(); group.blocksRaycasts =false; image.sprite = GetComponent ().sprite; /// 生成的物品不影响射线检测 image.SetNativeSize(); if(m_DraggingIcon !=null) ...
