最有效的方式来切换按钮打开和关闭功能的脚本
本文关键字：功能 脚本 按钮 方式 有效 | 更新日期: 2023-09-27 18:03:10
我编写了一段代码来更改按钮的视觉状态(单击哪个按钮将突出显示为蓝色，并将所有其他按钮返回为默认颜色)。它似乎工作得很好，但感觉很麻烦。是否有更有效/简洁的方法来重写我的代码?很多谢谢!
using UnityEngine ;
using System.Collections ;
using UnityEngine.UI ;
public class ToolButtons : MonoBehaviour
{
public Color activeColor ;
public Color inactiveColor ;
public GameObject iconBG ;
public Button ink, brush, crayon, pencil, spray, eraser, chnageColor, brushSize, undo, redo, clear, newAnimal ;
public GameObject inkIconBG, brushIconBG, crayonIconBG, pencilIconBG, sprayIconBG, eraserIconBG, changeColorIconBG, brushSizeIconBG ;
void Start ()
{
inactiveColor = iconBG.GetComponent <Image> ().color ;
}
// Use this for initialization
void buttonCallBack (Button buttonClicked)
{
//Change Color Palette Button clicked
if (buttonClicked == ink)
{
inkIconBG.GetComponent <Image> ().color = activeColor ;
} else if (buttonClicked != ink)
{
inkIconBG.GetComponent <Image> ().color = inactiveColor ;
}
if (buttonClicked == brush)
{
brushIconBG.GetComponent <Image> ().color = activeColor ;
} else if (buttonClicked != brush)
{
brushIconBG.GetComponent <Image> ().color = inactiveColor ;
}
if (buttonClicked == crayon)
{
crayonIconBG.GetComponent <Image> ().color = activeColor ;
} else if (buttonClicked != crayon)
{
crayonIconBG.GetComponent <Image> ().color = inactiveColor ;
}
if (buttonClicked == pencil)
{
pencilIconBG.GetComponent <Image> ().color = activeColor ;
} else if (buttonClicked != pencil)
{
pencilIconBG.GetComponent <Image> ().color = inactiveColor ;
}
if (buttonClicked == spray)
{
sprayIconBG.GetComponent <Image> ().color = activeColor ;
} else if (buttonClicked != spray)
{
sprayIconBG.GetComponent <Image> ().color = inactiveColor ;
}
if (buttonClicked == eraser)
{
eraserIconBG.GetComponent <Image> ().color = activeColor ;
} else if (buttonClicked != eraser)
{
eraserIconBG.GetComponent <Image> ().color = inactiveColor ;
}
}
void OnEnable ()
{
ink.onClick.AddListener (() => buttonCallBack (ink)) ;
brush.onClick.AddListener (() => buttonCallBack (brush)) ;
crayon.onClick.AddListener (() => buttonCallBack (crayon)) ;
pencil.onClick.AddListener (() => buttonCallBack (pencil)) ;
spray.onClick.AddListener (() => buttonCallBack (spray)) ;
eraser.onClick.AddListener (() => buttonCallBack (eraser)) ;
}
void OnDisable ()
{
}
}
用数组做这个会更好，但问题是你会丢失你的按钮和GameObjects的名称，这使得以后很难修改你的代码。
您可以使用Dictionary。制作Button—GameObject对，然后手动添加每个Button来匹配每个图标/GameObject。然后，您可以在单击Button时循环它，将单击的Button与Dictionary中的键进行比较，然后根据比较结果分配activeColor或inactiveColor。
注意:如果您添加了更多的按钮和图标，您必须将它们也添加到pairButtonIcon()函数中。
有人想知道为什么我不使用foreach循环在Dictionary，这是因为它分配内存在Unity
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using UnityEngine.UI;
public class ToolButtons : MonoBehaviour
{
public Color activeColor;
public Color inactiveColor;
public GameObject iconBG;
public Button ink, brush, crayon, pencil, spray, eraser, chnageColor, brushSize, undo, redo, clear, newAnimal;
public GameObject inkIconBG, brushIconBG, crayonIconBG, pencilIconBG, sprayIconBG, eraserIconBG, changeColorIconBG, brushSizeIconBG;
Dictionary<Button, GameObject> buttonIconPair = new Dictionary<Button, GameObject>();
void pairButtonIcon()
{
buttonIconPair.Add(ink, inkIconBG);
buttonIconPair.Add(brush, brushIconBG);
buttonIconPair.Add(crayon, crayonIconBG);
buttonIconPair.Add(pencil, pencilIconBG);
buttonIconPair.Add(spray, sprayIconBG);
buttonIconPair.Add(eraser, eraserIconBG);
buttonIconPair.Add(chnageColor, changeColorIconBG);
buttonIconPair.Add(brushSize, brushSizeIconBG);
}
void Start()
{
pairButtonIcon();
inactiveColor = iconBG.GetComponent<Image>().color;
}
// Use this for initialization
void buttonCallBack(Button buttonClicked)
{
//My Code
for (int i = 0; i < buttonIconPair.Count; i++)
{
var item = buttonIconPair.ElementAt(i);
var itemKey = item.Key;
var itemValue = item.Value;
if (buttonClicked == itemKey)
{
itemValue.GetComponent<Image>().color = activeColor;
}
else
{
itemValue.GetComponent<Image>().color = inactiveColor;
}
}
}
void OnEnable()
{
ink.onClick.AddListener(() => buttonCallBack(ink));
brush.onClick.AddListener(() => buttonCallBack(brush));
crayon.onClick.AddListener(() => buttonCallBack(crayon));
pencil.onClick.AddListener(() => buttonCallBack(pencil));
spray.onClick.AddListener(() => buttonCallBack(spray));
eraser.onClick.AddListener(() => buttonCallBack(eraser));
}
void OnDisable()
{
}
}
EDIT:你也可以使用多个Lists，然后在每个Button和GameObject/Icon上存储。
public class ToolButtons : MonoBehaviour
{
public Color activeColor;
public Color inactiveColor;
public GameObject iconBG;
public Button ink, brush, crayon, pencil, spray, eraser, chnageColor, brushSize, undo, redo, clear, newAnimal;
public GameObject inkIconBG, brushIconBG, crayonIconBG, pencilIconBG, sprayIconBG, eraserIconBG, changeColorIconBG, brushSizeIconBG;
List<Button> button = new List<Button>();
List<GameObject> iconGameObjects = new List<GameObject>();
void pairButtonIcon()
{
button.Add(ink);
iconGameObjects.Add(inkIconBG);
button.Add(brush);
iconGameObjects.Add(brushIconBG);
button.Add(crayon);
iconGameObjects.Add(crayonIconBG);
button.Add(pencil);
iconGameObjects.Add(pencilIconBG);
button.Add(spray);
iconGameObjects.Add(sprayIconBG);
button.Add(eraser);
iconGameObjects.Add(eraserIconBG);
button.Add(chnageColor);
iconGameObjects.Add(changeColorIconBG);
button.Add(brushSize);
iconGameObjects.Add(brushSizeIconBG);
}
void Start()
{
pairButtonIcon();
inactiveColor = iconBG.GetComponent<Image>().color;
}
// Use this for initialization
void buttonCallBack(Button buttonClicked)
{
//My Code
for (int i = 0; i < button.Count; i++)
{
if (buttonClicked == button[i])
{
iconGameObjects[i].GetComponent<Image>().color = activeColor;
}
else
{
iconGameObjects[i].GetComponent<Image>().color = inactiveColor;
}
}
}
void OnEnable()
{
ink.onClick.AddListener(() => buttonCallBack(ink));
brush.onClick.AddListener(() => buttonCallBack(brush));
crayon.onClick.AddListener(() => buttonCallBack(crayon));
pencil.onClick.AddListener(() => buttonCallBack(pencil));
spray.onClick.AddListener(() => buttonCallBack(spray));
eraser.onClick.AddListener(() => buttonCallBack(eraser));
}
void OnDisable()
{
}
}
