flash - blinking movieclip with timer -

-

i trying make movieclip blink, blinks when hit something, create effect of game.i have hit test when hitted, caught called on object.the caught function of object make stop , start blink based on timer.my timer set on new timer(400); why object not blink? conditions seem correct.

if (hit.hittestobject(f.hit))     f.caught();       private function blinkinghandler(evt:timerevent):void     {          _canblink = true;         if (_canblink)         {             this.alpha = 0;             _canblink = false;             this.alpha = 100;             trace("blinking");         }     }     public function caught() : void     {            _blinktimer.start();           //removeeventlistener(event.enter_frame, loop);          //this.stop();     }

first, i'm going assume have added event listener trigger blinkinghandler call when timer fires:

_blinktimer.addeventlistener(timerevent.timer, blinkinghandler);

now, blinkinghandler have posted never hide object. alpha set 0, set 1 in same call, net result alpha not display @ 0. must set alpha 0, let few frames render, set 1 on next timer tick, , on. try this:

private function blinkinghandler(evt:timerevent):void {     if(_canblink) this.alpha = 1;     else this.alpha = 0;     _canblink = !_canblink; }

you do:

visible = !visible;

to toggle visibility on each timer tick.

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
