![]() ![]() Hacks used in AS2 to get by accessing hidden methods will no longer work in AS3.How do I properly draw one vector object onto a specific position of another in ActionScript, accounting for positioning, transparency, etc? Something to keep in mind that access control for AS3 is also enforced not only during compile time, but also runtime. Only helper classes can extend other helper classes and they need to be in the same file. Note: your primary class cannot extend a helper class. Other access attributes within helper classes behave as expected. Helper classes themselves are inherently internal in this respect (and do not need to be explicitly provided any form of access attribute). Since helper classes don't technically belong in packages, internal access for them is restricted to the classes in the current file. Internal is the default for every class and class member except constructors which are always public.Īccess control in helper classes are a little different. Classes in other packages do not have access. Classes in the same package have access to all internal members of any other class in that package. Internal: Internal access is similar to public access but is restricted to package definitions. Private members are accessible directly off of class instances only when done so within the class definition.Ĭlasses and constructors cannot be defined as private. ![]() This means that subclasses can even define new members of the same name and not have a conflict since the private member of the superclass is completely hidden. To all other classes, even subclasses, a private member doesn't even exist. Now, with AS3, private is completely private and is only accessible from within the class in which it is defined. Private: AS2 had the private attribute but it worked more like protected as subclasses had full access to private members. Attempting to access a protected variable from another class instance in any circumstance will result in an error.Ĭlasses and constructors cannot be defined as protected. It sets variables hidden from all access except from subclasses accessing the variables (inherited) from their own instance. Protected: The protected attribute is a new attribute for ActionScript. Anything defined as public can be accessed anywhere by anything. ![]() Public: The public attribute is the same as it was in ActionScript 2. In ActionScript 3 you have the following attributes for controlling access: Sorry if these are all retarded, just trying to get a head start :)ĪctionScript 3 introduces 2 new access attributes for classes and members and refines the private attribute of ActionScript 2. and in the bounceIt function it creates a new tween and bounces the ball up and down. there is a circle movieclip made with a class, function called bounceIt. Does that class file exist on my computer? or is it in the flash player? can i use mx classes? if so where are those located for AS 3?Īny help would be appriciated, i am pretty much looking for a simple example like. I hunted through all the class files, and those still all look flash 8.Ĭan ya gimme a hint as to how to get going tweening things with AS3? I know i could make my own timers and do it myself, but I am looking to find out what happened to the Tween Class.Īlso where does flash store the class files i am importing. but that doesnt work, nor do i think it should. I attempted to do import mx.effects.Tween. NEW Question, and maybe I am just all together spacing out on this one. Because of that, as would fail.Ĭonversion functions are typically the class name called as a function, though simple casting will be used if there is no actual casting function associated with the class (with, for example, your custom classes String, however, is a unique conversion function). When converting a number to a string, you would use a conversion function (String()) because Numbers do not inherit from String. Though you'd generally want to stick with the constructor class since it is more appropriate to your object.Ĭonversion functions are used to convert a value to another value of a different type. Sprite -DisplayObjectContainer -InteractiveObject -DisplayObject -EventDispatcher -Object as would also work to change the value's type to any other object within the Sprite's heirarchy: ![]() So if an object is a Sprite and it was returned from a function as a Display Object (such as getChildAt would do), then you would most likely want to use as to reassociate it's type to be a Sprite. By compatible I mean the original variable's class or any type within that class's hierarchy. how come i am getting null, maybe i am just not understanding this, but shouldnt those do the same thing?Ĭasting with the as operator does not convert a datatype, it only changes Flash's understanding of what that variable's type is and only if compatible. ![]()
