Basics of AS3
OPTION F9 == Actions Panel
- The difference between AS2 and AS3:
AS2: my_MC.createTextField("instance_name", 10,0,0 Stage.width, 22); my_MC.attachMovie("MC_name", "moviename_mc, this.getNextHighestDepth()); 10,0,0,Stage.width == dimensions 22 == depth Versus AS3: var myText:TextField = new TextField(); var myMC:MovieClip = new MovieClip(); now in AS3 you dont have to createTextField or attachMovie, and you can define all the variables later.
- select the property (highlighted in blue in the Actions panel), and press F1 to see a help menu telling you about what values the property can have.
- strings must be in quotation marks (var userName:<DataType> = "Data";)
- you assign data type to the variable so you dont lose track of what it is.
- trace(variableName);
- trace("long text comment");
- function thing():void - the void means no return argument
function moveObj(thing:MovieClip):void { thing.y -= 50; // mc moves 50px up thing.rotation += 45; // mc rotates 45 degrees right } moveObj(thing1_mc);
function moveObj(thing:MovieClip, movement:Number, rotationAmount:Number):void { thing.y -= movement; // mc moves 50px up thing.rotation += rotationAmount; // mc rotates 45 degrees right } moveObj(thing1_mc, 50, 45);
function moveObj():Number // the number here defines what kind of thing is returned { thing1_mc.y -= 50; thing1_mc.scaleY = 2; return thing1_mc.y; } thing2_mc.y = moveObj();
- events must have listeners
