First we load in the class:
1 | import flash.display.MovieClip |
Then we define a new movie-clip:
1 | var newEmptyMovieclip:MovieClip = new MovieClip() |
Alter its properties:
1 | newEmptyMovieclip.name = "box" |
And finally add it to the stage:
1 | addChild(lineOfSight) |
The old code for creating a movieclip (and drawing) was as follows:
1 2 3 4 5 6 7 8 9 10 11 | //AS2 this.createEmptyMovieClip("Object", this.getNextHighestDepth()) Object.beginFill(0xFF0000) Object.moveTo(0, 0) Object.lineTo(100, 0) Object.lineTo(100, 100) Object.lineTo(0, 100) Object.lineTo(0, 0) Object.endFill() Object._x = 100 Object._y = 50 |
The previous code and the following do the same thing, look at their differences.
1 2 3 4 5 6 7 8 | //AS3 var Object:MovieClip = new MovieClip() Object.graphics.beginFill(0xFF0000) Object.graphics.drawRect(0, 0, 100, 100) Object.graphics.endFill() Object.x = 100 Object.y = 50 addChild(mc) |
We firstly see function changes in the creation of the MovieClip. Then we see the lineTo and moveTo functions not used, instead a rectangle draw function is called. Also, instead of simply drawing into the MovieClip, it is drawn into the graphics property. Please note, the MovieClip isn’t actually added to the stage until the addChild function is called.
In the early stages of me learning flash I had everything I needed off the stage and moved them when I needed, but that’s dumb… Especially when you can dynamically attach them:
1 | movieClipStorage = _root.attachMovie("box", "box1", _root.getNextHighestDepth(), {_x:50, _y:100}) |
So, we attach the library referenced movie clip “box” to the _root naming it “box1″ at the highest depth with the _x property as 50 and the _y property as 100 and storing it in the variable movieClipStorage.
But, how do we make a movieclip reference?
Goto your movieclip (in the library) > right click > properties > check advanced > export for actionscript and then in the Identifier box type in your reference (in the above example i would put “box” (no quotes))
