I have two point p1 and p2 and I want to designate coordinates of the point that is exactly between them. So I used the Point.distance method to designate the distance between them but I don't know what to do next to achieve my goal.
View 3 RepliesI am developing a software in flash in which I need to draw some points in a movie clip dynamically with moveTo() and lineTo() during the runtime of the software. However, later in the future (during runtime), given the (x,y) coordinates of a point, I need to know if this specific point is part of the curve I drew before. Is there a way of doing that without saving the (x,y) coordinates of all the points I have drawn in the movie clip?

View 2 RepliesI am trying to scale a movieclip with AS3, but always using the center of the stage as the registration point. The movieclip is larger than the stage to begin with, and uses a slider component to slide back and forth. I'd like to be able to scale the movieclip using a button, but it currently uses it's own registration point (upper left corner) as the source.
Is there a way to force the scale to use the center of the stage?
I have a flvplayback component onto which I am loading a video. To mimic next frame and previous frame actions I am adding cue points to the loaded for every second of its length. The next frame /previous frame functions implement seekToNextNavCuePoint and seekToPrevNavCuePoint on the video. But its not working the way I expected it to.
Here is the actual class file. You can directly compile it with an fla file containing button instances in the library for play pause stop... Also you would need some sample flv file.

I'm attempting to make a curve drawing tool a bit easier to use.Rather than drawing a basic curve and then clicking on the control point to change it, I would like the user to be able to click on the curve itself to change it, much as you do in the FlashIDE.So, given start and end points, and a point on the curve, how do you determine the control point for use with the MX API?(I googled this, but found mostly info on cubic rather than quadratic curves)

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?

It might be that I don't understand what their "sign()" method does. I thought it was Math.sin().

how I can count the B point's coordinates (see attached image... or not as I am a new user...pf!). I know the arrow's rotation - so the angle (let's say it is -120), A's coordinates (0, 0) - A is the middle point of the arrow, and that the distance between A and B is 50 px.
View 1 RepliesI'm importing an external image, but by default the anchor point (coordinates 0,0) for the movieclip it loads into is the top left,this is obviously an issue if I want to rotate, as I need coordinates (0,0) to be the centre of the image, not the top left?
View 2 RepliesWhat I have going on is basically a sideshow. I have six monsters/creatures separated into three parts under the top, middle and bottom layers. I have six arrows (already working buttons) to control previous and next functions (action script already working and on a loop). My end goal is to have the prev/next arrows control the appropriate top, middle, or bottom section making all the monsters/creatures interchangeable. ex:cat ears, monkey eyes, robot mouth ect...
Here is my problem: I don't know how to designate the top, middle, or bottom arrows to control the appropriate layer. In test mode all arrows are currently switching all layers.[code]...
I have a set of dots displayed on the canvas (key bits of code pulled out):
// Drop points based on x y coords
for (var i = 0; i < 50; i++) {
itemPoint[i] = new mcDot();[code]....
how to redraw the lines as I move a dot. Also there could be many lines connected to any single dot. Do I need to somehow register which lines are connected to which dot? How do I redrew the lines based on this?
i'm a novice to ActionScript but from failed Google function searches, i think i've choosen an advanced i hope possible task: how to read then apply bezier, anchor point and handle positions to different anchor points. What i need to do is precisely align a rectangular closed bezier path with a randomly shaped closed bezier path, both with the same number of anchor points.
View 9 RepliesI am developing a game for mobile in AIR (as3). I have created some bots for this game that initially just wander around. But when a bonus enters the stage, they have to move to the bonus.The detection of a new bonus and moving of the bots works fine, but there is something wrong with the manipulation when a new bonus enters the stage.Basically, this is how it works (or I try to make it work):My bot moves along with his rotation as a parameter. (works fine)
private function moveToNextLocation():void
{
var angle:Number = _rotation * 0.0174532925; // 1 degree = 0.0174532925 radians
var speedX:Number = Math.sin(angle) * _speed;

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);
Im making a little app in flash using papervision I want to make a regular movieClip show up in the same place as a papervision object. The coordinates seem like perspective is affecting the number displayed.
View 2 RepliesI have been tasked with trying to create a drawing tool that draws dotted lines as you drag the mouse across the stage. I can easily capture the points on MouseEvent.MOUSE_MOVE and store them in a vector and then draw the points as dots:
The problem is that I need to calculate evenly distributed points on an ever growing Vector of points so I can only draw the line between say every 5th point (say using modulus). I have been battling away with Bezier curve equations both Quadratic and Cubic but still can't quite figure out how to convert my Vector of points into an evenly distributed Vector of Points without sucking the life from the CPU.
Im pushing Point locations into an array to Shift em out later. like this:
tempmoves.push([new Point(roundx,roundy)]);
..
ob.movestoplayer = tempmoves;[code]....
What am i doing wrong?
It's been a long time since I've done any work with actionscript, and alas I've forgotten nearly everything. I've tried to look for a tutorial that would explain basic animation with actionscript, but the one that I found on Kirupa was no longer there.
Basically I'd like to do this:On the stage I have a movieclip and I'd like the movieclip to move along the x-axis to a certain point and then back to the starting point again. The moving speed of the movieclip should also be adjustable.
I'm creating a game in flash for a university project, and learning actionscript and programming as I go. I'm very much still at a beginner level - at the moment al I have is some actionscript for drawing rectangles and moving them about the screen. This is what I'm having trouble with at the moment: I have a class called 'Creature', and I want instances of it to interact with each other. I want them to do something when they come within a certain distance of another instance. And I want them to be able to pick a random other instance to get the location of, in order to do something with that information.
What I think I need is: A function for telling the distance between two (x,y) points.
A way of referencing the nearest other instance of the class. And a way of randomly selecting from all of the instances of the class.
How to convert 3d point to 2d point? I've found next formula in Internet(camera is situated in origin)
[Code]....
But these formulae give me strange result when z are less than zero(z<0) I need build line from A(100,100,100) to B (100,100;-100) As you can see these equations give really strange result when I try to convert B point in 2D dimension
i have the follow issue :
I have a point which is setted at the border on a component, with changed transform point to the center of a component in order to match the component rotation.
the important part is when i try to get the point XY after rotation - they remains the same as before rotation.
how to get XY, after rotation ( changeing point.rotation property to specific degrees of rotaion )
I am using AS2 with Flash 8 Professional So, my problem is that I currently have a man in the middle of the screen, who shoots a line towards the mouse when I click. However, when I use hitTest to see if the line collides with another object, Flash recognizes the line as a large box if it is diagonal, so the hitTest isn't very accurate. The line only satys there for one frame, so I can't have the usual moving-bullet-style. I am either looking for a way to create an imaginary line with AS from the starting point to the mouse and beyond, and tell whether or not this line intersects with an object... or some other way that I haven't thought of to fix my problem. Keep in mind that the line rotates from a center point towards anywhere around it for 360 degrees.
