This will hide the titleScreen movie clip (intro and title of the game) on the release event and startgame function will be called. titleScreen.onRelease = function() { this._visible = false; startgame(); } this._visible = false;hides titleScreen movie clip

AD 206 Intermediate CG : School of Art and Design : University of Illinois at Chicago : Spring 2009 Whack A Capsule Initialize variable whacks to 0 (the score) And display it in the whacks_txt dynamic text field in the scoreDisplay movie clip whacks = 0; scoreDisplay.whack_txt.text = whacks;

AD 206 Intermediate CG : School of Art and Design : University of Illinois at Chicago : Spring 2009 Whack A Capsule getTimer() function returns the number of milliseconds elapsed since the game started to execute endTime variablewill take 30 seconds into the future To determine an amount of time remaining in the game endTime = getTimer() ;

AD 206 Intermediate CG : School of Art and Design : University of Illinois at Chicago : Spring 2009 Whack A Capsule Main timeline function that keeps the time and determines when the game is over etimekeeps track of remaining time between the endTime and now (from getTimer) getTimer() constantly changing causing etime to get smaller as time elapses var etime = endTime - getTimer();

AD 206 Intermediate CG : School of Art and Design : University of Illinois at Chicago : Spring 2009 Whack A Capsule IF remaining time is lass then 0 then “ TimeUP” message is displayed on the dynamic test field time_txt in the scoreDisplay movie clip _root.onEnterFrame = function() { var etime = endTime - getTimer(); if (etime <= 0) { scoreDisplay.time_txt.text = "Time Up";

AD 206 Intermediate CG : School of Art and Design : University of Illinois at Chicago : Spring 2009 Whack A Capsule And functions assigned to capsules are deleted onPress, onEnterFrame, stops capsules at current position, and kills timer function in the main timeline for (var i = 0; i < 9; i++) { var nm = "m" + i; delete _root[nm].onPress; delete _root[nm].onEnterFrame; _root[nm].stop(); delete _root.onEnterFrame; }

AD 206 Intermediate CG : School of Art and Design : University of Illinois at Chicago : Spring 2009 Whack A Capsule If there is still time remaining in the game the time is displayed in the text field time_txt with the wrold “sec” etime/1000 returns number of seconds Math.ceilrounds up floating point value to the nearest integer else { scoreDisplay.time_txt.text = Math.ceil(etime / 1000) + " sec"; }

AD 206 Intermediate CG : School of Art and Design : University of Illinois at Chicago : Spring 2009 Whack A Capsule Fades away the movie clip from 100% to 0% in 10 frames _root[nm].onEnterFrame = function() { this._alpha -= 10; if (this._alpha <= 10) { delete this.onEnterFrame; this.removeMovieClip(); }

AD 206 Intermediate CG : School of Art and Design : University of Illinois at Chicago : Spring 2009 Whack A Capsule wcnt++; wcnt %= 5; The value of wcnt will be always 0, 1, 2, 3, 4, 0, 1, 2, 3, 4, 0, …. It is unlikely that the user will have more then 5 on screens at once because they fade away quickly
