在拼UI的过程中会添加很多图片文字,但是很容易会忽略其中一点就是把无用的RaycastTarget去掉,因为开启此选项,虽然此组建虽然不需要接受射线,但是它而然工作且消耗性能


在网上找了2个小工具:
- 其中一个是在Editor模式下用蓝色框出启用RatcastTarget的组件

Code如下。挂在任意GameObject上即可
#if UNITY_EDITOR
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class DebugUILine : MonoBehaviour
{
static Vector3[] fourCorners = new Vector3[4];
void OnDrawGizmos()
{
foreach (MaskableGraphic g in GameObject.FindObjectsOfType<MaskableGraphic>())
{
if (g.raycastTarget)
{
RectTransform rectTransform = g.transform as RectTransform;
rectTransform.GetWorldCorners(fourCorners);
Gizmos.color = Color.blue;
for (int i = 0; i < 4; i++)
Gizmos.DrawLine(fourCorners[i], fourCorners[(i + 1) % 4]);
}
}
}
}
#endif
- 第二个是自动取消创建对应Image Text 的RaycastTarget选项(重写unity创建对应组件,创建组建后自动取消选项)
Code 如下
using UnityEngine;
using System.Collections;
using UnityEditor;
using UnityEngine.UI;
public class UITools
{
/// <summary>
/// 自动取消RatcastTarget
/// </summary>
[MenuItem("GameObject/UI/Image")]
static void CreatImage()
{
if (Selection.activeTransform)
{
if (Selection.activeTransform.GetComponentInParent<Canvas>())
{
GameObject go = new GameObject("image", typeof(Image));
go.GetComponent<Image>().raycastTarget = false;
go.transform.SetParent(Selection.activeTransform);
}
}
}
//重写Create->UI->Text事件
[MenuItem("GameObject/UI/Text")]
static void CreatText()
{
if (Selection.activeTransform)
{
//如果选中的是列表里的Canvas
if (Selection.activeTransform.GetComponentInParent<Canvas>())
{
//新建Text对象
GameObject go = new GameObject("text", typeof(Text));
//将raycastTarget置为false
go.GetComponent<Text>().raycastTarget = false;
//设置其父物体
go.transform.SetParent(Selection.activeTransform);
}
}
}
//重写Create->UI->Text事件
[MenuItem("GameObject/UI/Raw Image")]
static void CreatRawImage()
{
if (Selection.activeTransform)
{
//如果选中的是列表里的Canvas
if (Selection.activeTransform.GetComponentInParent<Canvas>())
{
//新建Text对象
GameObject go = new GameObject("RawImage", typeof(RawImage));
//将raycastTarget置为false
go.GetComponent<RawImage>().raycastTarget = false;
//设置其父物体
go.transform.SetParent(Selection.activeTransform);
}
}
}
}
