Flash :: Use Graphics (for Ex) Methods Without Prefixing An Instance Variable?
Jun 28, 2011
I'm new to AS3 and HaXe, but was hoping to find a way to use methods from a final class (Graphics) without always prefixing an instance variable.Instead of something like this:
var gr:Graphics = flash.Lib.current.graphics;
gr.clear();
gr.beginFill(0xffffff, 1);
gr.drawRect(0,0,400,400);
I was hoping to get something that works like processing.org, but I guess a lot of the convenience there comes from the preprocessing. I looked at the HaXe reference on advanced types (http://haxe.org/ref/type_advanced), but I haven't been able to make anything work so far. This probably isn't possible since Graphics is final, but I thought it wouldn't hurt to ask. It seems it would be easy if I could extend Graphics
- I link a MyClip class with a simple trace in the constructor;
- I export the whole file as MyClip.SWC;
In the Second File:
- I go to Edit > Preferences > ActionScript > ActionScript 3 settings and I add
-in the Library Path- the file MyClip.SWC;
- on the first frame of this swf I write var myClip:MyClip = new MyClip(); addChild(myClip);
I don't know what I'm doing wrong but when I compile (export swf) the class gets loaded (I see the trace in the output window) BUT I can't see the graphics associated to MyClip. It seems MyClip.SWC only contains the code of that clip.
I am trying to delete a single line using graphics.clear() method but it clears all the instance of lines created by lineTo() method. I want to remove a single line upon click from bunch of its multiple instance.
As we know whent here is no such variable of null value assignment to a variable or instance flash throws this kind of Error.In one of my Application i need to get more flashVariables, They may or maynot come as FLASHVARS. But when i miss any variable flash thows this error as an alert box. is there any simple solution to avoid this kind of issue
when i use try,Catch statement the issue will not come, But i don't like to write Bunch of try,catch statement for all this kind of variables.
i have a main movie. i use a loader to load a "example.swf" file. then i place that file inside a holder movieclip. in example.swf, i have an instance of a class i just wrote. this class has some particular methods. from my main movie, i want to call the methods of the instance of my class i have in example.swf. how can i do that??? i know it's a kind of casting, but none seems to work.
I have recently adopted an FLV from someone else. It is structured "unconventionally" at best. For this reason (and because I am not well-versed in AS3), I haven't been able to get a pause/play button to function properly. About the file, The project is a 6-7 minute demo for a new product complete with voiceover. You have to drill in 3 movie clips deep before you can get to much of the animation. There are gotoAndPlay functions at the end of each 3rd-level movie clip that refer to a frame on the 2nd level.
On the 2nd-level frame, there is a stop function which allows the next movie clip to play. Each movie clip contains a sound layer for voice over. About the play/pause button. The instance name is pauseBtn. The button code below is on the 1st frame of the main timeline. There is a keyframe on the second frame for another bit of code. The button itself is a 2-frame MC that spans the entire main timeline. The event.target.gotoAndStop() lines are working properly to change the look of the button.
My button scriptstop(); import flash.media.SoundMixer; var pp:Boolean = true; function ppState(event:MouseEvent) { if(pp) { stop(); [Code] .....
What happens when I test the movieThe animation plays without problem as long as the button is not clicked. I haven't been able to see a pattern in the chaos that occurs when the button is clicked. Sometimes nothing happens. Sometimes it stops the sound only. Sometimes it resets to the beginning of the movie. Sometimes it starts play random parts on top of what was already playing.
This error appears in the output pane. TypeError: Error #1009: Cannot access a property or method of a null object reference. at NameOfTheFile_fla::MainTimeline/chk()
I'm working on a video player and I initially developed the player with everything in the .FLA file with no classes. Then I started modularizing my player into classes and realised that my classes are static methods rather than instance methods which doesn't seem to be needed in my player. My question is - is this a bad design to have all of your classes methods to be static rather than instance methods ? As I dont see the need (yet) so that's why i geared more towards static methods, is this a bad design?
Im new to AS3.[code]I have above code in a movieclip which i have Exported as a Class.But when i run it says "Constructor functions must be instance methods".
changed one of my methods to static and it worked for what I was trying to do but I would like to know what is the difference between static and instance method.
What is the difference between static and instance methods?
I am follwoing a tutorial on linda.com about creating a website in Flash everything was going well until i started trying to copy the action script in the online examples now I keep getting this error message and can't figure out how to get rid of it:
This has been a long-standing curiosity of mine, and I haven't gotten around to profiling to find out, and haven't seen it asked yet (for AS3):Let's say that I have a class:
class MyClass { public function myMethod():String { return "some return value";
I have an application I am developing, a part of which involves a number of icons on a page - when you roll your mouse over an icon, the movie moves forward a frame, and a text area is populated with text, fed from a php file (which pulls data from a MySQL database). Each icon pulls in a different value, depending on the values in the php file.
I have this working a treat - see code below. The only problem is I need to create a seperate button / mc for each icon with the appropriate references on - in the code example below, the icon populates message.text - this.message2 - message2 is a value in the php file. So the next symbol would be message3, etc.
on (rollOver) { myData = new LoadVars(); myData.onLoad = function() { message.text = this.message2;
[code]....
I will need a large number of these icons, all with different values, so I would like to create a generic button that looks at it's instance name, and uses this for the numbered variable - i.e. the 2 in "message2".
How can I obtain the position of a instance whose name is stored in an variable? If there is a instance whose name I don't know, but the instance's name is store in an variable x. How can I obtain its position?
I now have it so that when I click on any instance of "star", I'm taken to another frame, and in that frame I'd like to be able to look up the variable "startype" for that particular instance only. How exactly can I do this?
I was wondering about MC and hey can help to lag a game out. I set up an advanced class system so i don't have to use MC to simulate walls, all i use isthe x,y,width and height. Well anyway since i don't need MC anymore I was wondering if there is a way to attach Graphics instead of MC cause a Graphics file size is relatively small than that of a graphic, I think. If anyone could tell me thats true and show me a way to attach graphics that would be nice. I haven't tried it yet but maybe if I exported the graphic from the library imihgt be able to call its name, but it doesn't have an instance name so im stuck.
Ok, I've been at this for 2 days now, and really need some assistance. It seems like it should be so simple!
The part that doesn't work [code]...
Then that button in the root should be able to take the value that is in the variable "critter_pressed_new" and use that as the instance name, to make that particular mc go away.
Simple question: I'm trying to use a variable to call on different instance names:
[Code]...
The code in red is the issue in question. In this example, I'm trying to add a child called "pic_2", with the number two called from the variable "picCaller"
I have multiple inputs which I would like to limit the input on. Not limit to number of characters but limit to the actual input box. The problem is the limit script is not reading the variable I am sending to the function and is returning as undefined.
ActionScript Code: function Limit(SetText){ oKey = new Object(); var __text0:String = "";
I am trying to create an animation that will cycle through letters (each of which have an instance name) by using a loop. I have a variable which it outputting the numbers i need if just used in a tract but i want to add it to the end of the instance name so that each instance scales one after the other. Any way of delaying each one by a few few seconds (or milliseconds if I remember the acrionscript unit of time correctly).
Basically I am having errors when trying to use a variable to set my instance name.
Here is the code:
ActionScript Code: var i:Number = 1; ["button"+i].transform.colorTransform=myColorTransform; //doesn't work button2.transform.colorTransform=myColorTransform;//works
'i' will always carry the button number.
I've tried all the methods I can think of so I am hoping that one of you can give me a hand, if I can figure this out I can probably save a few hundred lines of code in an app I have just started on.
