ActionScript 3.0 :: Finding Coordinates With 2 Objects
Nov 30, 2009
I get the feeling the title is misleading... What I try to achieve is quite simple (at least it sounds like a simple thing to do). I am trying to find the intersection of 2 objects in relation to each other. One of them is the character for my game, and the other is the obstacle (the floor, a barrel, etc). I need to find the coordinates of the character in relation to the obstacle. Here's a picture to make it a bit clearer:
Here the coordinates (and the cross) represent the origin of my objects, and the two squares are my character (twice to better represent the multiple possibilities). The number after the slash for the square is what I should get as the .x when my character hits the obstacle. I tried using getBounds(), but I really don't know about it and tried stuff based on the little knowledge I have about it (I won't post the code here, first it was horrible, and it also didn't survive the rage I had trying to get this to work...).

I'm in the process of making a board game in Flash; as part of process of getting fully to grips with Flash AS3.
I have a JPEG of the original board. This contains ~ 1000 circles that players may move pieces between. Pretty standard board-game stuff. The circles are not in any way regularly spaced.
So far, I've drawn the circles in Flash, by hand, and positioned them where they need to be. This looks great - I can see all my places.
What I want to do now is create these circles programatically. I want to be able to do this so I can adjust how the spaces look (depending on game state). Eventually I'll want to be able to zoom / pan the entire game board as well.
My question is, is there a way of tagging each circle with a unique reference and then looping through and recording locations?
I'm thinking something a bit like the Javascript DOM "getElementsByTagName" or similar.
At the moment I can only see two options:
Convert each circle to a symbol and give it a unique class name so I can access it from code Go through and write down the X/Y of each circle (add to my DB of board locations that I already have) so I can plot them programatically

I'd like to use the x and y mouse coordinates as variables in a program. I'm very new to Flash and ActionScript and I'm not even sure which classes I need to import or which listeners or handlers I need to use.

We have a client server architecture where a C++ server talks to Flash clients. I'm developing the server and would like to send through tcp an xy coord to simulate a button press where the receiving flash client would find the topmost visible object at that coord and send a mouse event to it such that we could simulate play without a human present. I'm told this is incredibly difficult, but it seems to me that there must be a way to do this. Am I off the mark? Or is there a mechanism in flash to iterate through all objects regardless of parent child relationships to find a visible button at an x, y coord and signal a press event?

I have made a few posts now, and I'd like to especially Prid for not only answering them, but for giving me guidance on how to learn AS2. I am progressing very nicely, and have made a couple of simple games without any tutorials, but theres one thing I couldn't find. I have this character which can move, up and down, left and right. I also have an enemy trying to shoot at him. However, this enemy needs to know where the character is. I already have the shooting code (Prid), but it was for shooting in the direction of the mouse. What I need now is to replace the bit of code that finds the mouse coordinates with code that finds the coordinates of the player.
The shooting code is on the frame (doubt that is important to say, but still) and the instance AND name of the Character is, well, Character. So basically, I need a code to calculate coordinates of a movie clip that does not have a fixed position. Oh and one more thing, should I post simple stuff like this in the beginner section, because I've seen waaay more complicated stuff there than in the AS2 section.

I have a line dynamically drawn in a coordinatesystem. The line is drawn by the user. Now I wonder if there is a way to find out where the line crosses the y-axis. I know about hittest but how can I get exacltly where (x- and y-coordinates) for the hitpoint?

i've been working on a problem for a while now, which involves targeting the closest movieClip in relation to the x y coords of the mouse, I've attached a nice little acompanying graphic.Each mc added to the stage has it's own sub-class (HotSpots) which uses Pythag to measure distance from mouse. At this stage i can determine the closest value from my Main class but can't figure out how to reference it back to the movieclip... hope this makes sense. Below are the two Classes.My Main Class which attachs the mcs, and monitors mouse movement and traces closest value.[code]

I have a Movieclip (MC1) with and moving object (OBJ1) inside it and using AS3. I want to do a hit test on it with another object (OBJ2) that is on the stage. Normally I would just do MC1.x + OBJ1.x to get my coords for the hit test. But how do I do it if MC1 has been rotated?

Imagine two movieclips, both on the same Y axis. I want one MC to be able to diagonally move to the other MC X axis, all while making a perfect diagonal line until it reaches 100y. So just like this picture, that MC moves in a perfect diagonal until it matches the other MC.x, and 100y (no matter what, it can't go past 100y but must equal 100y). I probably made it sound more complicated than it is.

Is there any way to find out about all the objects being on the stage?I mean, all nested in other movieClips or Sprites too.I can find children of specific object by looping it with getChildAt(), but of course I would have to do this for all the objects in their levels that they are nested in..

need a method of finding all the objects over the top of another object...
I realise I could use hitTest to check if something is intersecting, but I can't use it to find the names of the said objects. I also realise I could just cycle through all the objects on the stage and calculate it that way, but considering there's over 300 objects that could 'possibly' be covering this particular object, thats a lot to calculate, and i'd like it to be snappy...

I have two columns of objects on stage, one on the left side column (A) and one on the right side (column B). Each column has 3 objects in it. For this quiz I want the user to be able to draw a line from each object in column A to the corresponding object in column B.To do this I need to capture the xy coordinates of the first object that the user clicks on and then capture the coordinates of the 2nd object the user clicks on so that I can draw a line between the two of them. Drawing the line is no problem but how do I capture the coordinates of the first object selected and then the 2nd object selected? This is as far as I've got with the code.
var clip:Shape = new Shape()
var startX=0
var startY=0

I have a MovieClip on my stage. Inside the MovieClip there are a few buttons (all MovieClips also) and a mask layer to keep anything on the outside invisible.
Problem: My MouseEvent fires and should move objectA into position over objectB. All code in the script tells me it has moved. Tracing the x,y coordinates of objectA also tells me it has moved. The Alpha on objectA is 100% and it is positioned on the topmost layer beneath the mask layer. All this tells me that when the object moves, it should be visible on the stage (the event moves the object into the masked area). Testing disproves everything. The traces all tell me the object is where it is supposed to be but it cannot be seen. I don't understand this and it, amongst other AS3 hiccups, is seriously turning me off Flash as it seems to be a waste of time to try and learn as it seems like 90% of the scripts written will fail 90% of the time.

My stage contains an object that contains a child. The child sees it's x and y position in relation to it's parent, so when the object moves, the coordinates remain the same.
How do i get a child's coordinates relative to the stage?

two balls are stationary on stage and I am dragging ball 1 between them. I want my program to deny the ability to do this (technical terms) and move the ball automatically to the closest point available that does not overlap either of the other two balls i.e. the left side of the dragged ball may touch but not over lap ball 3. I have a feeling the circular equation: (x-a)^2 + (Y-b)^2 = c comes into it but it may need pythagoras instead as the balls are all circular but not all the same size. The best way I can see for this is to write a multi-part equation for the bounds of boths balls and then finding the nearest point, but not sure how to do this in as3, perhaps using the 'for each' tag.

I am looking to create an animation (perhaps frame by frame) that corresponds with the coordinates of an object. Specifically, I want to have a draggable object's coordinates (locked to the x-axis) indicate where the playhead of a specific movie clip should be. In other words, let's say that I have a 100px wide stage and I want each px location of an object on that stage to correspond to a particular frame of a movieclip. In concept, I feel that it should be as easy as loading an objects coordinates into a variable, then passing that variable on with a simple math equation, adjusting it for movieclip length... but right about then my brain gets fried. Finding out how to lock a draggable object to the x-axis has been pretty easy, but from there I'm stumped. I'm not particularly well versed in AS3 but I do like to think I understand the concepts.

Is there a way to have a function draw a box around an object by finding the objects instance name via a string?
such as:
Code:
function BoxObject(object) {
//code to draw a box around the object
}
and then juts have an object with an instance name, like "my_mc" and then call the function on a keyframe like:
BoxObject("my_mc");

is it possible for flash to detect off-stage mouse coordinates in order to continuously drag an object within its bounds while the mouse is moving outside of the stage? for example: i have a draggable red square on my stage. the stage is the bounds of the drag. if i drag the red square to the bottom of the stage and continue to drag outside of and around the stage, i'd like the red square to continue moving within it's bounds, following the mouse coordinates. currently, dragging halts as soon as i leave the stage and the red square only begins to move with the mouse coordinates if i reenter the stage bounds.

I'm building a dynamic content page in flash that consists of using attachMovieClip and createEmptyMovieClip with coordinates to place photos and objects, which are loaded from an external source and scrolling their thumbnails I've run into a problem setting the variables correctly because the scrolling thumbnails required that the thumbnails be nested inside a scrolling controller clip and that has somehow messed up my preloading and sequential text caption loading for the tumbnails.

I was trying to convert global coordinates to local coordinates of a UIComplenent in my flex project using below code using below code
var gp:Point = new Point(e.stageX,e.stageY); //global point
var lp:Point = uic.globalToLocal(gp); //local point
uic is UIComponent in which I have subclass of Sprite for drawing something I have set the sprite's mouseEnabled and mouseChildren to false to not interrupt the mouse event. above code is within uic's mousemove event where I was tracing the gp and lp gp was giving correct value and suprisingly lp was giving negetive values. when I move the move to the top left corner of uic i expect lp to be 0,0 but it is giving the -width of of uic. I broke my head for hours and ended up finding an alternate by using offsets. Infact my original code was much simpler like this which was same issue
var lp:Point = new Point(e.localX,e.localY);
I am not sure what exactly is causing this problem. the workaround had lot of issues and it creating a mess in my rest of the algorithms.Just now I found even more interesting thing (which is actually weird). for some reason I went and create a new lp2
var lp2:Point = new Point(e.localX,e.localY);
now surprisingly it was giving correct values as expected and I went back and changed the code as
var gp:Point = new Point(e.stageX,e.stageY); //global point
var lp:Point = uic.globalToLocal(gp); //local point
var lp2:Point = new Point(e.localX,e.localY);
var lp2:Point = uic.globalToLocal(gp);
now it is expected to have all the lp, lp2 and lp3 variables to be same but weiredly lp two is giving wrong value and lp2 and lp3 were giving correct. I am suspecting using the variable lp has something to do. I am not sure about that but above proves it so right now I am using lp2.

I was reading the 'Isometric Transformations' tutorial by Danko Kozar and I have a few questions. I understand what all the code does, but not how it does it. First of all, how does the following code work:
transforms x,y,z coordinates into Flash x coordinate
xFla = function (x, y, z) {
// cartesian coordinates[code].....
I understand that it converts 3d coordinates to 2d coordinates, but I don't understand how. What numbers whould be punched into x, y, and z to acquire certain desired effects?Also, what's the difference between moveTo and lineTo:
red line
style(1, "0xFF0000", 100);
plot(0, 0, 0);
draw(200, 0, 0);
