ActionScript 2.0 :: How To Use LocalToGlobal Scope
Nov 5, 2006
i am teaching myself how to use localToGlobal(), and i seem to be running into a scoping snag, at least i THINK it is a scoping snag. So when i use Code:
[Code].....
i get the desired effect, yippee. That is to say, the output says 299, which is what the global coordinate of the movie is. However when i try use the same code in the main time line like this
I have a Debug class I've written, and I'd like to include a static trace() method in there, unfortunately I have no idea how to then access global / top level trace as effectively I've blocked it with the local static scope.[code]
I have a bunch of enemy ships in a container on the stage.I am moving the container around every second and I'm creating bullets that the enemy ship are firing.So I need to have the bullets get created on the stage where the enemy ship is located currently so I can have it y-- on an enter frame event.The Y coordiantes are accurate but for some reason the X coordinates get scaled across the screen. So the first enemy ship is only off by 10 pixels or so, but the 2nd ship, the bullet gets created about 50-60 pixels over to the right.Is there any reason why the Y would be right but the X isn't?[code]
I have a some objects of same class type prgramatically generated on the stage.Inside these objects which are generally at x=300 on the stage is the code:
Code: this.x+=2.3; trace(parent.localToGlobal(new Point(this.x,this.y)), ", ", this.x , " ", this.y); A sample of the trace output is as follows.. (x=2.3, y=0) , 2.3 0
Now im expecting some values in there somewhere to indicate its absolute location on the stage, ie, x=300.This isnt happening.Whats the correct syntax i should be using.Bare in mind these object will be of any name on the stage and will be dynamically created so its not easy to just reference their mc names.
I'm adding several instances of an MC (bread_mc) into a container MC (wall_mc). wall_mc has been added to a shop class and that is where i'm called the rest of my functions from. Also the wall_mc is scrolled left and right with mouseX & mouseY values. I've set up a function to add the bread_mc to the wall at different x/y positions.
[Code]...
I really don't even know if i'm using it right, But I think my problem lies in the fact that I need the currMC path to travel up the display list tree and get the global stage X/Y position. I'm not too sure how to implement a dynamic path with the localToGlobal method.
i just cant make this function work. Using addChild player mc is added to stage, inside it theres a mc named ballCnt. I need to make that position global, but it keeps giving local coordinates. Heres the code line (the last one i tryed):
var point:Point = localToGlobal(new Point(player.ballCnt.x, player.ballCnt.y)); trace(point);
I have a movie clip that is nested inside 2 other clips and want to get it's coordinates on the stage. I am using the localToGlobal method but it is returning the wrong values. Here is my code:[AS]
var myPoint = new Point(this.skew_mc.grid_mc.dot_mc.x, this.skew_mc.grid_mc.dot_mc.y); var newPoint = this.skew_mc.grid_mc.dot_mc.localToGlobal(myP); trace(newP);[/AS]
I've attached an fla with an example of this in. If anyone can point out where I'm going wrong .
Let's say i have a 3 movieclips which are nested one in other like this:A-> B-> CAnd i would like to find out C movie clip (which is in B mc and B mc is in A mc) coordinates relative to global stage, how can i accomplish that?
I'm making a driving game in Flash Mx 2004, and I based my code in MarkFeller Game,but I can't make the code works, now I'm with problems in the skid routine, flash dont give me any error, but the code don't works (the LineTo and MoveTo dont do anything) and I think that my problem is with localToGlobal function....
I have a movieclip A inside a movieclip B. A has a coords (10, 0) and B has a coords (0, 0). So technically the global point for A should be (10, 0) right? Well it's giving me (20, 0). I put A at (10, 10) and I get (20, 20). This is just the weirdest thing ever.
Say I have a movieclip called theScreen a 0,0. It is 800 wide, 700 hightheScreen contains a movieclip called theStatusArea at 600,0. It is 200 wide by 700 hightheStausArea contains a movieClip called pieces at 10, 410. It is 180 wide by 180 highpieces contains a number of movieclips (triangle, square, etc.),all of these sub movieclips are more narrow than the pieces container and are all set added to the pieces container at 0,0
var pt:Point = new Point(triangle.x, triangle.y) pt= triangle.localToGlobal(pt); trace(pt); // should be 610, 410 at least at the start.
What I'm having the problem with is the proper usage of localToGlobal method. I have the hero mc, I put into it another mc called 'weapon'. Now, in the game, I want to fire a projectile and set it at the x and y of the weapon. The question is, how can I access the absolute x and y of the weapon.
My problems keep piling up. I was trying to figure out where child objects X and Y positions are on stage and not locally. Therefore i use the "localToGlobal" function and I'm pretty sure i use it correctly? The thing is that some Y values are true but the X are just completely spaced out. I use a function to find all child objects on stage and this works great.
Code: private function findGameElements():void { // Array that will store all elements on screen and their values fixedElements = new Array();
I got 23 boxes (box1, box2...) inside two movieclips (Circle.SizeableCircle). I need to bring all these to the front, using localToGlobal.This brings box1 to the front (or whatever it's called):
PHP Code: var cpBox1:Point=new Point(Circle.SizeableCircle.box1.x,Circle.SizeableCircle.box1.y);var gpBox1:Point=Circle.SizeableCircle.box1.parent.localToGlobal(cpBox1);
I have a small problem with usage localToGlobal and than back to local. I can get global coordinate of my nested mc in question alright. Than i check if this coordinate + value of my mc.width is more than my stage width. I get to this part with no problem. Than if value is bigger (so mc is not on the stage i mean if part is off the stage i change value so it is stage width - mc.width). So i get value in global coordinates that i need. But how do i apply this to my nested clip is my question? For reference here is my code:
Ive tried looking in a whole bunch of threads for a solution to this probably common issue but to no avail.I have a bunch of objects of same type on the stage which are generated through code.Inside these objects which are generally at x=300 on the stage.
stage1 is the stage object I pass into my class.The trace output is as follows
(x=2.3, y=0) , 2.3 0
Now im expecting some values in there somewhere to indicate its actual location on the stage, ie, x=300.This isnt happening.Whats the correct syntax i should be using.
I'm working on an isometric-view prototype game, and I thought a good way to do the collision detection would be to put four empty movie clips on each of the character's base corners (it's a cube), convert those corner's _x and _y to the Stage, and go from there. Problem is, how to get it to work.My character is on the stage in an otherwise empty "clip" MovieClip. Here's what I have inside my character:
Code: onClipEvent(enterFrame){ var point:Object = new Object(); point.rightX = right._x;[code]....
Whenever I trace any of these, it always traces the local coordinates. Otherwise, everything is fine.
I seem to be having difficulty in using the contents of a variable whan i receive the data from the database the script places the contents in a variable called myText1This I need to access outside the function.This is part of the script below.
mypath = "http://192.168.0.100/fedpest/pestReports/" mypath1 =mypath + "exterior.php"; var sendData = new LoadVars();
I have a function, and inside of it is a LoadVars object to load a variable. The problem is that I need the outer function to return the results of the LoadVars' return.
I have made a script, and now has come the point when I need to use removechild. Whenever I try this I get an error. After looking at the problem, I think I need to learn more about scope and packages. I think if I put everything in the correct scope, I will be able to use the removechild command. I tried to make all my vars public, so that removechild would work, however I got an error that anything public needs to be in a package. I tried to add the package part to my script, but got the error that packages cant be nested. I tried some other things and still no luck, just more errors.
So, if anyone could point me to a tutorial, or recommend a book or something, that will help teach me about scope and packages, Or if you are feeling patient and generous, and you think you could explain this problem to a 5 year old, please explain it to me the way you would to said 5 year old. If you maybe think you can help me out on the script, it can be found here: [URL]
A question about the variable within the for loop it is always stuck on False -- even if the first condition gets achieved.I read that the for loop variable is treated as if it is completely seperate varibale from the one in the main even if they have the same name
I'v attached a listener to a movieclip on stage but I can access any "global" varaiables which are out side the listeners function.I lose the scope or something what can i do about it? here is some code.
PHP Code player.controlbar.muteButton.addEventListener(MouseEvent.CLICK,mute0,false,0,true); public function mute0(e:MouseEvent):void {
I have 2 methods in a actionscript class.[code]I get duplicate variable warning. Is the local variable scope not limited to the method. Can't I declare same name variable in multiple methods?
