My timer increases speed after a single play through of my game why? <p>I continue to get the error TypeError: Error #1009: Cannot access a property or method of a null object reference. at ChazS1127_win_loose_screen_fla::MainTimeline/updateTime() at flash.utils::Timer/_timerDispatch() at flash.utils::Timer/tick() and here is my code for my main game</p> <pre><code>stop(); import flash.events.MouseEvent; import flash.ui.Mouse; import flash.events.TimerEvent; import flash.utils.Timer; var timer:Timer = new Timer(1000, 9999); timer.addEventListener(TimerEvent.TIMER, updateTime); var timeRemaining = 30; timerBox.text = timeRemaining; function updateTime(evt:TimerEvent) { timeRemaining--; timerBox.text = timeRemaining; if(timeRemaining &lt;= 0) { gotoAndStop(1, "Loose Screen"); } } addEventListener(MouseEvent.CLICK, onMouseClick); var score = 0 ; function onMouseClick(evt:MouseEvent) { if(evt.target.name == "playBtn") { texts.visible = false; playBtn.visible = false; backpackss.visible = false; backgrounds.visible = false; timer.start(); } if(evt.target.name == "Backpack") { Backpack.visible = false; message.text = "A backpack is a necessity for carrying all your items."; score = score + 1; scoredisplay.text = "score:" + score; 0 } if(evt.target.name == "Bandage") { Bandage.visible = false; message.text = "Bandages for cuts and scraps and to keep from bleeding out."; score = score + 1; scoredisplay.text = "score:" + score; } if(evt.target.name == "Brace") { Brace.visible = false; message.text = "A brace is good for a sprain or even a break in a bone allow you to keep going."; score = score + 1; scoredisplay.text = "score:" + score; } if(evt.target.name == "canned") { canned.visible = false; message.text = "Canned foods are a good resource as food will be scarce in situations."; score = score + 1; scoredisplay.text = "score:" + score; } if(evt.target.name == "Compass") { Compass.visible = false; message.text = "Going the wrong direction in a survival situation can be your downfall."; score = score + 1; scoredisplay.text = "score:" + score; } if(evt.target.name == "Flashlight") { Flashlight.visible = false; message.text = "A flashlight can help you see at night and help you stay sane."; score = score + 1; scoredisplay.text = "score:" + score; } if(evt.target.name == "Iodine") { Iodine.visible = false; message.text = "An ioddine purfication kit can assist in keeping water clean for drinking."; score = score + 1; scoredisplay.text = "score:" + score; } if(evt.target.name == "Lighter") { Lighter.visible = false; message.text = "A windproof lighter for even the windest of days to light fires."; score = score + 1; scoredisplay.text = "score:" + score; } if(evt.target.name == "Radio") { Radio.visible = false; message.text = "A radio to help keep up to date on news around if it's still brodcasting."; score = score + 1; scoredisplay.text = "score:" + score; } if(evt.target.name == "Sewing") { Sewing.visible = false; message.text = "A sewing kit for salvaging clothes and for patching up wounds."; score = score + 1; scoredisplay.text = "score:" + score; } if(evt.target.name == "Tent") { Tent.visible = false; message.text = "A tent can be a home for the night and a home for life."; score = score + 1; scoredisplay.text = "score:" + score; } if(score &gt;= 11) { gotoAndStop(1, "Victory Screen"); } } function removeAllEvents() { removeEventListener(MouseEvent.CLICK, onMouseClick); timer.removeEventListener(TimerEvent.TIMER, updateTime); timer.stop(); } </code></pre> <p>and my Victory Screen</p> <pre><code>stop(); import flash.events.MouseEvent; addEventListener(MouseEvent.CLICK, onMouseClick2); play(); function onMouseClick2(evt:MouseEvent) { if(evt.target.name == "restartButton") { gotoAndStop(1, "Main Game"); removeAllEvents2(); } } function removeAllEvents2() { removeEventListener(MouseEvent.CLICK, onMouseClick2); } </code></pre> <p>and my loose screen</p> <pre><code>stop(); import flash.events.MouseEvent; play(); addEventListener(MouseEvent.CLICK, onMouseClick2); function onMouseClick3(evt:MouseEvent) { if(evt.target.name == "restartButton") { gotoAndStop(1, "Main Game"); removeAllEvents3(); } } function removeAllEvents3() { removeEventListener(MouseEvent.CLICK, onMouseClick3); } </code></pre> <p>so why does my game when through one play the timer will speed up and go fast for no reason. After one play through it'll go 2 seconds for every 1 second and so on.</p>
