The function is pretty simple, although the syntax is very different. In this case, I'm using a mouse event called click and creating a function called onClick.īutton_mc.addEventListener(MouseEvent.CLICK, onClick) The event listener has two arguments, the type of event and a function that will be triggered when that event occurs.
Flash actionscript 3.0 code for buttons movie#
You can still use buttons in Flash, but here I'm using a Movie Clip object as a button called 'button_mc.' I need to add an event listener to the object. Var link:URLRequest = new URLRequest("") The code is a lot longer than in the previous example, but the result is the same.įirst, we start off by declaring a variable which will hold the URL we want to go to: Event handlers are now more precise in AS 3.0 and it requires the aid of event listeners to trigger functions. All scripts now must reside in the timeline or in an external file.Īlso, that on (release) statement above makes some assumptions about what is going to be released and what object will be engaged when that event occurs. Touted as a full-fledged programming language, it has some characteristics built into it that make it work more like other web programming languages and less like JavaScript, which is a good thing but will take some time getting used to.įor example, in AS 2.0, if I wanted to script a button to take me to a URL, I would simply select the button on the stage and write the following action in the Actions panel: ActionScript 3.0 is very different from its predecessors.
