I have this code for a message to appear on stage when player finishes drag and drop. I would like this sprite to be removed when a button is clicked for the next frame. Can someone help me with the code?
stage.addEventListener(Event.ENTER_FRAME, EntFrame);
function EntFrame (e:Event):void
{
if (CntP1+CntP2+CntP3+CntP4+CntP5+CntP6+CntP7+CntP8 == 40)
{
var w:int = 400, h:int = 200;
var win:Sprite = new Sprite();
win.name = "Mywin";
addChild(win);
// draw rounded rect with subtle vertical linear gradient fill and blue stroke
win.graphics.lineStyle(4,0x0077ff);
var mat:Matrix = new Matrix();
mat.createGradientBox(w, h, 90 * (Math.PI / 180));
win.graphics.beginGradientFill(GradientType.LINEAR,[0xffffff,0xeeeeee],[1.00,1.00],[0,255],mat);
win.graphics.drawRoundRect(0,0,w,h,15,15);
// show center "YOU WIN!" text
var tf:TextField = new TextField();
tf.autoSize = TextFieldAutoSize.LEFT;
tf.antiAliasType = AntiAliasType.ADVANCED;
tf.defaultTextFormat = new TextFormat("Arial, Verdana",36,0x454545,true);
tf.text = "Κέρδισες!";
tf.selectable = false;
win.addChild(tf);
tf.x = w/2 - tf.width/2;
tf.y = h/2 - tf.height/2;
// add a drop shadow
var dropShadow:DropShadowFilter = new DropShadowFilter(3,45,0,.35,8,8,1,3);
win.filters = [dropShadow];
// center the graphic
win.x = stage.stageWidth/2 - win.width/2;
win.y = stage.stageHeight/2 - win.height/2;
}
}
Your code isn't written well and needs rewriting to ensure reuse or scalability of your project, but here's a quick way out.
make a holder Sprite, something like
var messageHolder:Sprite = new Sprite();
addChild(messageHolder);
add all the messages to that holder in any fashion you like. When you need to erase the contents of that holder, call following method:
function clearHolderContents(holder:DisplayObjectContainer):void
{
if (holder.numChildren < 1)
return; // no need to continue this method if the target is empty
for (var i:int = holder.numChildren - 1; i >= 0; i--)
removeChild(holder.getChildAt(i));
}
This method can clear contents of any DisplayObjectContainer => use it for your messageHolder:
clearHolderContents(messageHolder);
Hope that helps!
