Er konden ook volledige spelletjes of geavanceerde applicaties mee worden gemaakt, waarbij er bijvoorbeeld interactie optreedt met de muis en het toetsenbord. ActionScript is een event-based taal, wat wil zeggen dat alle acties getriggerd worden door events (gebeurtenissen). </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Inleiding">Inleiding</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=ActionScript&veaction=edit&section=1" title="Bewerk dit kopje: Inleiding" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=ActionScript&action=edit&section=1" title="De broncode bewerken van de sectie: Inleiding"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading3"><h3 id="Event-driven_of_event-based_programming">Event-driven of event-based programming</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=ActionScript&veaction=edit&section=2" title="Bewerk dit kopje: Event-driven of event-based programming" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=ActionScript&action=edit&section=2" title="De broncode bewerken van de sectie: Event-driven of event-based programming"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Men spreekt bij programmeren van event-based of <a href="/w/index.php?title=Event-driven_programming&action=edit&redlink=1" class="new" title="Event-driven programming (de pagina bestaat niet)">event-driven programming</a> wanneer de <a href="/wiki/Control_flow" title="Control flow">control flow</a> van het programma bepaald wordt door acties, bijvoorbeeld het klikken met de muis, of door berichten van andere programma's/threads. </p> <div class="mw-heading mw-heading3"><h3 id="ECMA-262">ECMA-262</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=ActionScript&veaction=edit&section=3" title="Bewerk dit kopje: ECMA-262" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=ActionScript&action=edit&section=3" title="De broncode bewerken van de sectie: ECMA-262"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>ActionScript is gebaseerd op de <a href="/wiki/ECMAScript" title="ECMAScript">ECMA-262</a> (European Computer Manufactureres Association) standaard.

Deze werd verbeterd, en werd meteen de eerste echte versie van ActionScript. Het was ook meteen de eerste versie die invloeden had van JavaScript en de ECMA-262. Dit werd geïntroduceerd samen met Flash Player 5. ActionScript kon nu ook ontwikkeld worden in een gewone tekstverwerker, zoals kladblok, in plaats van acties te selecteren uit uitklapmenu's, zoals het geval was bij Actions. Met het uitkomen van Flash Player 6 werden er niet al te veel wijzigingen doorgevoerd. Er waren enkel kleine veranderingen zoals het toevoegen van de strikt gelijk operator (===) zodat het meer ECMA-262-conform was. Een belangrijk kenmerk van ActionScript 1.0 ten opzichte van latere versies is het gebruik van "loose typing", ofwel <a href="/wiki/Typesysteem#Zwakke_typering" title="Typesysteem">zwakke typering</a>. Dit wil zeggen dat <a href="/wiki/Variabele_(informatica)" title="Variabele (informatica)">variabelen</a> in de code eender welk soort data konden bevatten. </p> <div class="mw-heading mw-heading4"><h4 id="2003-2006">2003-2006</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=ActionScript&veaction=edit&section=7" title="Bewerk dit kopje: 2003-2006" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=ActionScript&action=edit&section=7" title="De broncode bewerken van de sectie: 2003-2006"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>ActionScript 2.0 was een grote verandering voor de taal. De taal werd in gebruik genomen in september 2003, samen met het uitbrengen van Flash Player 7. Hoewel de code al meer gericht was op het <a href="/wiki/Objectgeori%C3%ABnteerd" title="Objectgeoriënteerd">OOP</a> (objectgeoriënteerd programmeren), werd de code nog altijd naar ActionScript 1.0-<a href="/wiki/Bytecode" title="Bytecode">bytecode</a> gecompileerd, zodat de code nog compatibel was met Flash Player 6. </p><p>Met ActionScript 2.0 werd het ook mogelijk voor programmeurs om een vast datatype te binden aan een variabele. Zo kunnen type mismatch fouten gevonden worden tijdens het compileren. Een type mismatch is bijvoorbeeld het toewijzen van een string (stukje tekst) aan een variabele van het type Number. </p> <div class="mw-heading mw-heading4"><h4 id="2006-nu">2006-nu</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=ActionScript&veaction=edit&section=8" title="Bewerk dit kopje: 2006-nu" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=ActionScript&action=edit&section=8" title="De broncode bewerken van de sectie: 2006-nu"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>ActionScript 3.0 werd geïntroduceerd in juni 2006. Het werd uitgebracht samen met Flash Player 9. AS 3.0 ging gepaard met een fundamentele herstructurering. Zo fundamenteel zelfs dat de nieuwe Flash player een volledig andere virtuele machine gebruikt. Flash player 9 gebruikt 2 <a href="/wiki/Virtuele_machine" title="Virtuele machine">virtuele machines</a> (VM's): één VM voor AS 1.0- en AS 2.0-code, en één VM voor AS 3.0. </p> <div class="mw-heading mw-heading3"><h3 id="Flash_Player-geschiedenis">Flash Player-geschiedenis</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=ActionScript&veaction=edit&section=9" title="Bewerk dit kopje: Flash Player-geschiedenis" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=ActionScript&action=edit&section=9" title="De broncode bewerken van de sectie: Flash Player-geschiedenis"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <table class="wikitable" style="width: 100%"> <tbody><tr> <th>Flash Player-versie</th> <th>Datum</th> <th>Kenmerken </th></tr> <tr> <td>Flash Player 2</td> <td>1997</td> <td>Knoppen, bibliotheken, <a href="/wiki/Tweening" title="Tweening">tweening</a>, stereo audio. <p>Er waren enkele basis functies zoals Stop(), GotoAndPlay(), en dergelijke voor de <i>timeline control</i>.

title="Compiler">gecompileerd</a> worden vooraleer het uitgevoerd kan worden. Dit compileren zorgt ervoor dat de code wordt omgezet naar bytecode of <a href="/wiki/Machinetaal" title="Machinetaal">machinetaal</a>. Het project wordt zo samengevat in één bestand. Bij Flash is dit bijvoorbeeld een .swf-file (swiff-file uitgesproken). Er zijn echter programma's beschikbaar die een .swf-file terug kunnen omzetten naar hun originele broncode. Sommige programma's slagen hier vrij goed in, anderen zijn daar minder goed in. Dit decompileren houdt zekere risico's in. Zo moet er bijvoorbeeld geen vertrouwelijke informatie zoals wachtwoorden in de code opgeslagen worden aangezien deze gewoon gelezen kunnen worden. Maar er zijn nog problemen: het decompileren legt de broncode vrij. Dus als iemand een stuk code heeft geschreven dat eigenlijk niet bestemd is voor ieders ogen, dan kan dat een probleem vormen. Zo kunnen gebruikers bepaalde stukken in het programma gaan misbruiken of het onrechtmatig namaken. </p> <div class="mw-heading mw-heading3"><h3 id="Obfuscators">Obfuscators</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=ActionScript&veaction=edit&section=15" title="Bewerk dit kopje: Obfuscators" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=ActionScript&action=edit&section=15" title="De broncode bewerken van de sectie: Obfuscators"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Het onrechtmatig vrijleggen van de broncode van een project kan zeer lastig zijn. Er zijn echter programma's op de markt die de broncode tijdens of na het compileren onleesbaar proberen te maken en proberen tegen te gaan dat andere programma's de code kunnen decompileren, of de-assembleren. </p> <div class="mw-heading mw-heading2"><h2 id="Zie_ook">Zie ook</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a
