ActionScript 2.0 :: How To Use Prototypes Recently
Jul 25, 2004
I've been trying to learn how to use prototypes recently, and I want to make one that resizes a box, with elastic action. There is a button, and a box movieclip. What I want to happen is when you click the button, a prototype is run to resize the box. But, when I click the button, nothing happens. I feel I'm close, but lost :S
I am trying to access a function in a MovieClip that has been added to the stage. Right after loading in the function, I create a function that calls the function in the recently added MovieClip. The compiler does not recognize the Function and when I go into debug mode it shows up as null. I've tried declaring the function in the MovieClip using 3 different methods, but I get the same result.
Code: function Sleep(){ var Sleep = function(){ this.Sleep = function(){
What I find strange is that when I declare the function on the stage, it looks just fine and I can even see it (as a Function object) in the debug panel.
I am making an interactive Flash site and recently installed Papervision. I thought it would be cool to have a spinning 3D cube (using Papervision imports and so on). Unfortunately when I click on the 'Links' page (the 'links' keyframe with the AS3 actions) the cube appears, but when I got back to other pages (for example Homepage) the cube is still there!!
I was wondering how I unload/remove/un-import/?? this so that it works ONLY on that one keyframe.
I want to apply two different prototypes to one mc (one for movement, one for behavior), but both prototypes have onEnterFrames in them...so the one executed last works but the one executed before it won't.
(It may sound terribly ineffecient to have 2 prototypes for 1 mc, but one prototype is applied to many mcs, and the other is applied to only certains types of mcs (in this movie)).
A reference to the prototype object of a class or function object. The prototype property is automatically created and attached to any class or function object that you create.This property is static in that it is specific to the class or function that you create. For example, if you create a class, the value of the prototype property is shared by all instances of the class and is accessible only as a class property.Instances of your class cannot directly access the prototype property. A class's prototype object is a special instance of that class that provides a mechanism for sharing state across all instances of a class. At run time, when a property is not found on a class instance, the delegate, which is the class prototype object, is checked for that property. If the prototype object does not contain the property, the process continues with the prototype object's delegate checking in consecutively higher levels in the hierarchy until Flash Player or the Adobe Integrated Runtime finds the property.
Note: In ActionScript 3.0, prototype inheritance is not the primary mechanism for inheritance. Class inheritance, which drives the inheritance of fixed properties in class definitions, is the primary inheritance mechanism in ActionScript 3.0.
from this I get the impression that prototypes are just static variables.. am I right?
I have a movieclip prototype which I want to be applied to different movieclips every so often. The prototype controls it's movement, when it runs, the mc eases to a random x and y and stops. After that I want it to keep executing that movement prototype over and over, ie, keep moving around. I know how to use setInterval with functions, and I know movieclip prototypes basically are functions, but how can I get setInterval to work with movieclip prototypes assigned to specific movieclips?
I'd like to use an array/variable with the lmc 1.2 tweening prototypes. I can't seem to get this to work. Can anyone see anything wrong with this code:
Code: var myArray:Array = new Array("circle"); myArray[0].tween('_x', 400, 2,'easeInCubic', 0); I've also tried:
When you click each navigation button it slides to each section of pictures, each picture has an invisible button on top of it and each invisible button has its own individual instance name. When you click the picture (invisible button) it should load a seperate external swf into another movie clip I have set up. However because I have about 216 pictures (and hence 216 swfs) I dont want to have to make add a loadmovie on each button, that would get very repetitive and would increase the file size.
SO Im trying to be a smart coder here and do it dynamically. I KNOW this is possible. I want the swf to load based on the instance name of the button. I have seen this done with text files before using the _name command and it worked marvelously using loadvars so im just trying to do it using loadmovie instead.Have a look at my code.
//====================================== //========================Dynamic Movie load //this movie initializes 2 prototypes then assigns the prototypes to each button
So, right now when I want to find the distance between two points, I go: dist = Math.sqrt((this_x-that_x)*(this_x-that_x)+(this_y-that_y)*(this_y-that_y)) BLECH! I don't want to do that every time. So I want to make a nice little function that I can apply to an object. Problem is, I don't know how to do this. Is it possible to end up with something as easy as: Math.dist(thisclipname, thatclipname)? How do you guys set up functions that do bulky math and return nice clean numbers?
