I'm trying to do something very simple: animate a bunch of sprites so that, no matter where they are on the stage, they all go toward a single point (in this case, the center of the stage).
It only works for some of them. Some of them just sit there. I can't figure out why. I think its got something to do with atan2 and the way I'm using it, but I'm not sure what.
[Code]...
I video file using a cue point to show a movie clip at a certain spot. The movie clip becomes visual at the correct cue point however it doesn't animate, it shows the last frame of the animation and not the beginning.
View 2 RepliesIm pushing Point locations into an array to Shift em out later. like this:

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.

View 1 RepliesI am trying to develop a Quadratic Bezier Curve using the graphics.curveTo() method. Initially when i drag mouse to draw the shape, i use start point and end point of mouse to draw the curve line. I assume control point at any position below or up to the line. An draw the curve using this control point. some what like:-
[Code]...
Now i add a tip on this curve segment. I have x and y position of tip. I want to change the curve segment by dragging tip. but now i don't have the exact control point according to tip position. If i use tip coordinate as control point it reduce the height of curve and now tip does not lie on the curve segment. What i have to do is calculate the exact control point on the basis of tip coordinate. But i failed to get this point.
how to use these in order to make an object move from point A to point B in an arc.Think of that classic game where you have to input the angle and power and try to hit your opponent.
View 1 RepliesI'm trying to figure out how to find a point relative to the center of an object, modified by its rotation. For example, in the attached swf, I've been messing around trying to draw trails to a bitmap, coming out of the thrusters. I didn't have a problem at first, but as the ship rotated, the lines that were being drawn wouldn't remain relative.
http:[url]....
I'm sure this is because I have no idea what I'm doing, and I've just been sort of idioting my way through it. That aside, is there an easy way to find the point I'm looking for? For instance, say I want a point at Y -14 of my ship, but I want that to remain relative to the ship as it rotates.
From the Robert Penner code given in this tutorial: [URL] i was wondering why controlx and controly has to be so complicated. I've tried changing it to just _root._xmouse but it messes up. I don't get this, shouldn't the curve point be the same point as the mouse?

Basically what I like to ask is how to move a object from one point to another point based on the point tat you have clicked on a graph. For example, If I click on this coordinate (2,3) on graph, the object (movie clip) will move to that point.

View 2 RepliesSo created a Sprite to which I add other Sprites which are game tiles. Each tile is 60 x 60 px big. In result I've the Sprite with about 200 childs (those tiles).When I try to startDrag() the container sprite the lag when moving it is very noticeable..
Is there a way like to join the tile Sprites so the container would have only 1 child Sprite instead of 200? Because it lags so much probably cause it needs to move (change the x and y) all those 200 tiles.. Am I correct?In this case I can't use the cacheAsBitmap property, cause user can zoom in or zoom out the map..
I'm currently building a slideshow application using the MVC pattern, as it stands the application works by going to the next picture by clicking the photo or controlling the slides with a next/prev button.
i am trying to add additional navigation so that there are thumbnails of the images loaded with XML so the user can click the image and go straight to the image clicked on.
thats easy enough i could add buttons manually with thumbnails in them but it would tedious to update the photography or artwork when it comes to increasing or reducing the number of photos.
so what i plan is that ,when the application loads it reads and counts the images Thumnails in the XML file,then the AS3 generates thumbnail icons according to the amount of images counted in the XML File, then places them on the stage in a sequence next to each on the stage. as a sequence of thumnails with can then be used to navigate around the library with more control and is easy to update simply by changing the XML file.[code]...
