Last year I started working with AS3, and after having some startup problems, I’ve made my first application in it (not online yet).
\nThe strange thing is, I started a new project and when I had to make a button from a movieclip, I immediately wrote it in AS2… \ud83d\ude41<\/p>\n

That AS2 is embedded deep into my brain and probably more people have this problem.
\nSo I started this series of post about the stuff that’s changed in from AS2 to AS3<\/strong>.<\/p>\n

I will probably regurgitate what other people already wrote something about, but it’s my “travel” trough AS3 land.<\/p>\n

onRelease<\/h3>\n

One of things I use in every application that I build is onRelease.<\/p>\n

This is what the ActionScript 2.0 Migration<\/a> has to say about this:<\/p>\n\n\n\n
ActionScript 2.0<\/strong><\/td>\nActionScript 3.0<\/strong><\/td>\nComments<\/strong><\/td>\n<\/tr>\n
onRelease() EventHandler<\/td>\nflash.display.InteractiveObject dispatches event: mouseUp <\/td>\nReplaced in the new event model by a mouseUp event. <\/td>\n<\/tr>\n<\/table>\n

In AS2 I know 3 ways to use it:<\/p>\n

<\/p>\n

AS2<\/h3>\n

For this example you need a movieClip named ‘reload_mc<\/code>‘ and this AS2 code placed in the root<\/em><\/p>\n

example #1<\/b><\/p>\n

\/\/ #1\r\nthis.reload_mc.onRelease = function (){\r\n\ttrace ('onRelease AS2::reload button')\r\n}\r\n<\/code><\/pre>\n
example #2<\/b><\/p>\n
\/\/ #2\r\nthis.reload_mc.onRelease = reloadFunc;\r\n\r\nfunction reloadFunc () {\r\n\ttrace ('onRelease AS2::reload button')\r\n}\r\n<\/code><\/pre>\n
example #3<\/b><\/p>\n
\/\/ #3\r\nvar thisObj = this;\r\nthis.reload_mc.onRelease = function (){\r\n\tthisObj.reloadFunc ();\r\n}\r\nfunction reloadFunc () {\r\n\ttrace ('onRelease AS2::reload button')\r\n}<\/code><\/pre>\n
This a little different in AS3, but the good thing is I know of 2 ways to do this, but I only 1 can I explain.<\/p>\n
AS3<\/h3>\n
For this example you need a movieClip named ‘reload_mc<\/code>‘ and this AS2 code placed in the root<\/em>
\nExplanation: in AS3 everything is done by Listeners, and so onRelease <\/code>is replaced by MouseEvent.CLICK<\/code>, and to compare the code below and AS2 examples above I would say that example #2 is the AS2 example that resembles AS3 code.
\nExample #3 is the one I always use but that code is more complex, so that will be another post. <\/em><\/p>\n
example #1<\/b><\/p>\n
\n
import flash.events.MouseEvent;\r\n\r\nreload_mc.buttonMode = true; \/\/ show hand icon when mouse is over the movie clip\r\nreload_mc.addEventListener (MouseEvent.CLICK, reloadListener);\r\n\r\nfunction reloadListener ($event:MouseEvent) {\r\n\ttrace ('onRelease AS3::reload button')\r\n}\r\n<\/pre>\n<\/div>\n
<\/p>\n
\nBrendan Dawes<\/a> created files that helped me a lot: as3 for lazy bastards like me<\/a>.
\nI will probably write about the same subjects as he did in his files… But people who travel trough AS3 land will probably meet the same problems…<\/div>\n","protected":false},"excerpt":{"rendered":"
