本文介绍了通过调用名字变色的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
更新：不知道这code会的工作，但无法得到精灵，其中 c.getChildByName（spName）是空的名称， spName 是精灵的字符串名称。

解决方案
私人变种C：UIComponent =新UIComponent（）;
私人VAR S1：雪碧=新的Sprite（）;
私人VAR S2：雪碧=新的Sprite（）;
私有函数的init（）：无效
{
s1.name =shape1;
s2.name =shape2;
//确保S2不会出现在S1之上
s2.x = 100;
s1.addEventListener（的MouseEvent.MOUSE_DOWN，chgColorBlue）;
s1.addEventListener（侦听MouseEvent.MOUSE_UP，chgColorReset）;
c.addChild（S1）;
c.addChild（S2）;
的addElement（C）;
//改变shape1红色
changeSpriteColor（'shape1，0x990000）;
//改变shape2为灰色
changeSpriteColor（'shape2'，值0x777777）;
}
//通过调用其名称更改子画面的颜色
私有函数changeSpriteColor（spName：字符串，颜色：UINT）：无效
{
VAR孩子：雪碧= c.getChildByName（spName）作为精灵;
//确保儿童已被添加到容器
如果（孩子！= NULL）
shapeGraphics（孩子，颜色）;
}
//改变精灵的颜色
私有函数shapeGraphics（SP：雪碧，颜色：UINT）：无效
{
//确保清除图形，改变颜色之前
//还有其他的方法来改变颜色
//但我按照你的code！
sp.graphics.clear（）;
sp.graphics.beginFill（0x333333）;
sp.graphics.drawEllipse（7,35,18,12）;
sp.graphics.endFill（）;
}
私有函数chgColorBlue（E：MouseEvent）方法：无效
{
shapeGraphics（e.currentTarget，0x000099）;
}
私有函数chgColorReset（E：MouseEvent）方法：无效
{
shapeGraphics（e.currentTarget，0x333333）;
}
Update: Not sure if this code would work, but couldn't get the name of the sprite where c.getChildByName(spName) is null, spName is the string name of the sprite.
private var s:Sprite;
private var s2:Sprite;
private var c:UIComponent;
private var c2:UIComponent;
private function drawQuarterNotes(xx:int,ty:String):void {
if(ty=="up") {
s = new Sprite();
s2 = new Sprite();
c = new UIComponent();
c2 = new UIComponent();
s2.graphics.lineStyle(3,0x333333);
s2.graphics.moveTo(20,0);
s2.graphics.lineTo(20,50);
c2.addChild(s2);
c2.x = xx+16;
c2.y = xx-18;
s.graphics.beginFill(0x333333);
s.graphics.drawEllipse(7,35,18,12);
s.graphics.endFill();
s.name = "asd2";
s.addEventListener(MouseEvent.MOUSE_DOWN,chgColor);
s.addEventListener(MouseEvent.MOUSE_UP,chgColorReset);
c.addChild(s);
c.rotation = -20;
c.x = xx;
c.y = xx;
}
if(ty=="down") {
s2.graphics.lineStyle(3,0x333333);
s2.graphics.moveTo(20,0);
s2.graphics.lineTo(20,50);
c2.addChild(s2);
c2.x = xx+1;
c2.y = xx+35;
s.graphics.beginFill(0x333333);
s.graphics.drawEllipse(7,35,18,12);
s.graphics.endFill();
c.addChild(s);
c.rotation = -20;
c.x = xx;
c.y = xx;
}
addElement(c);
addElement(c2);
}
private function drawQuarterNotes2(xx:int,ty:String):void {
if(ty=="up") {
s = new Sprite();
s2 = new Sprite();
c = new UIComponent();
c2 = new UIComponent();
s2.graphics.lineStyle(3,0x333333);
s2.graphics.moveTo(20,0);
s2.graphics.lineTo(20,50);
c2.addChild(s2);
c2.x = xx+16;
c2.y = xx-18;
s.graphics.beginFill(0x333333);
s.graphics.drawEllipse(7,35,18,12);
s.graphics.endFill();
s.name = "asd1";
s.addEventListener(MouseEvent.MOUSE_DOWN,chgColor);
s.addEventListener(MouseEvent.MOUSE_UP,chgColorReset);

c.rotation = -20;
c.x = xx;
c.y = xx;
}
if(ty=="down") {
s2.graphics.lineStyle(3,0x333333);
s2.graphics.moveTo(20,0);
s2.graphics.lineTo(20,50);
c2.addChild(s2);
c2.x = xx+1;
c2.y = xx+35;
s.graphics.beginFill(0x333333);
s.graphics.drawEllipse(7,35,18,12);
s.graphics.endFill();
c.addChild(s);
c.rotation = -20;
c.x = xx;
c.y = xx;
}
addElement(c);
addElement(c2);
}
解决方案
private var c:UIComponent = new UIComponent();
private var s1:Sprite = new Sprite();
private var s2:Sprite = new Sprite();
private function init():void
{
s1.name = "shape1";
s2.name = "shape2";
//make sure s2 doesn't appear on top of s1
s2.x = 100;
s1.addEventListener(MouseEvent.MOUSE_DOWN, chgColorBlue);
s1.addEventListener(MouseEvent.MOUSE_UP, chgColorReset);
c.addChild(s1);
c.addChild(s2);
addElement(c);
//change shape1 to red
changeSpriteColor( 'shape1' , 0x990000 );
//change shape2 to grey
changeSpriteColor( 'shape2' , 0x777777 );
}
//change a sprite color by calling its name
private function changeSpriteColor( spName:String , color:uint ):void
{
var child:Sprite = c.getChildByName(spName ) as Sprite;
//make sure the child has been added to the container
if( child != null )
shapeGraphics( child , color );
}
//change a sprite color
private function shapeGraphics( sp:Sprite , color:uint ):void
{
//make sure to clear the graphics , before changing the color
//there are other ways to change the color
//but i'm following your code!
sp.graphics.clear();
sp.graphics.beginFill(0x333333);
sp.graphics.drawEllipse(7,35,18,12);
sp.graphics.endFill();
}
private function chgColorBlue(e:MouseEvent):void
{
shapeGraphics( e.currentTarget , 0x000099 );
}
private function chgColorReset(e:MouseEvent):void
{
shapeGraphics( e.currentTarget , 0x333333 );
}
