I'm editing the MotionPath LinePath2D by Greensock to make it become LinePath3D. However I'm stuck in editing this method:
[Code]....
I don't get the operations Greensock does to find the y and x inside the atan2. Why does he multiply xChange (which is a scalar and it should be the delta-x of the Line segment [IMG]) to the b component of the matrix and then sum it to the other thing?
[Code]....
Has anyone here ever developed a function (or general library of relevant functions) that will allow one to find the inverse of a matrix? I've searched the forum archives, as well as the internet more generally, but haven't found anything. If anyone has some leads, I hope you'll pass them along.
If I don't hear anything within the next few days, I might try to develop something on my own, but I'd hate to do so if someone has already done the dirty work.
A solution to this problem would be very useful for 3-D work or anyone doing mathematical programming more generally.
I am trying to use the same script, an image uploader (that uses PHP), twice to upload two different images into two different scroll panes using two different buttons, while displaying the current action in a text area.I would have thought this could be done by changing the names of the buttons etc and then changing them in the script to match, but I'm not entirely sure how to go about doing this (I am completely new to Flash!)
ActionScript Code:
//Allow this domain
System.security.allowDomain("http localhost/");

I've created a application where the viewer could change colours, add text, add logos, rotare them, etc... How do I create a reset button which resets everything to back normal in a specific FRAME? What functions do I have to use?
E.g.
Frame 5 is used to Add colours and text, etc...
Frame 10 is used to Add logos,scale them, rotate them, etc...
I need a reset button in Frame 5 to make only the things which were changed back to normal.
I need for my little project know a way to do following things:
- Getting any character from string (preferably operating on strings like on 1 dimensional arrays)
- Get ASCII code for character
- Convert number which contains ASCII code to character

View 1 RepliesSpecifically, I have a demo of a flash game (sort of super mario style). In it I have two types of weapon - a simple fire and big fireball. I reviewed the code in order to learn flash better [I am very new - since around monday this week].
I saw that the program has a variable that keeps track of the number of uses I have left in each weapon. I tried to review all the places this variable was used but I couldn't find where it affects the drawing onto the screen.
I even tried removing the variable declaration and then testing it - so I may find all references to the variable -- By the way any convinient way of finding all references to a variable/method/class [I am using ADOBE FLASH CS5.5]?
Also, I tried changing the variables starting value to "12" and I noticed that when I test the game, the weapon has 12 uses indeed.
So my problem:1. It seems that this variable is somehow affecting the drawing. Yet, I don't know how it does so since all the code I have found that uses this variable has nothing to do with drawing. It is all, logic, like
if(var <= 0){
var--;
} else{
return false;
}
Where is this influence coming from?get all references to a variable[like in eclipse ctrl+shift+g]?
For a long time I've been puzzled by the new System.totalMemory variable. Whenever I make an AS3 project, I try using the following code:

I've been using arrays and for loops in flash for some time now. Mostly successfully.But I'm missing some important understanding of how they really work. Here's the simple code that turns my head around and makes me realize I know nothing.[code]When I trace _root.term_array later in the code, it gives me the list of words and then a ton of 'undefined's. When I trace _root.term_array.length it says it's got 130 items. In my mind it should only have 13.
View 3 Repliesso I'm still learning the basic concepts. Attached to a movieclip used as a button I have this actionscript:
[Code]...
Which basically causes the movieclips 'leaf1' to shrink, 'vinefade' to go to its first frame, 'artween_mc' to unload, and for all other commands on this button to be disabled. I also want it to check another movieclip called 'leaf9', and see if it's current frame is at less than a particular frame number (73), because if so I want it to start playing forward. Once it reaches this frame number (73), I want to cause linkstween_mc to become visible and hit9button (also a movieclip) to become enabled. My current script does absolutely nothing to leaf9

View 5 RepliesI started out learning AS3 on my own a while ago without any programming experience whatsoever. I'm still in my diapers, but slowly progressing. Currently I'm working on a short animation with some code involved. Part of the animation is a herd of cows grazing in a pasture. I have a class called Cow which extends MovieClip and on the Cow timeline I have the walk cycle and other cow movements animated. When a cow is walking it slowly moves horizontally, along the x axis. I want the cows, when walking to also randomly move up and down (along the y axis) which would basically look as though the cow is moving further away or moving closer towards us. I'll be resizing each cow, according to its y position to create the effect of perspective (near and far).
What I'm trying to figure out is how to make the cow move either up or down the y axis in a somewhat random way. By "somewhat random" I mean that I don't want the cow to switch directions every second, but rather something like: 5 seconds moving up the y axis, then maybe 8 seconds moving down, then possibly 4 up, then 11 down, etc. It would be super if I could also have a velocity factor involved, meaning that when changing directions - from up to down, or down to up - I prefer that the change is smooth, like as in a ease out and then ease in.

View 40 RepliesI'm currently reading the book Learning ActionScript 3.0 and have dificulties understanding some programing basics due to my total lack of prior programing knowledge.For example now I'm looking at this script from the book that traces a list of all display objects on the stage and their children:[code]I understand everything except one thing. When there is an object with children (DisplayObjectContainer), the function traces the object but doesn't proceed and calls itself starting all over again this time analyzing the first child of the object. And if the child also have children itself the list will branch out until there is an object without children.What I don't understand is how the function at this point knows how to return to the last parent object and continue to analyzes its other children if any.For example when the function analyzes the stage of a scene with the following content how does the function know to continue analyzing child0. To me, looking at the code, I would expect the function to exit after listing [object StaticText]. I have hard time understanding what makes the function go back to largeContainer and continues with its child0 and so on.[code]This all what the book says regarding this which is not enough for me to understand this process:the function calls itself again. passing in the object currentlybeing inspected. This concept is called recursion. A function calling itself mayseem redundant, but it can be very useful. In this case, each time the functionis called, it receives a new display object to analyze, so the function reportsthe contents of that specific display object. The result is a complete walkthroughof all display objects, no matter how many children each may have.

My problem is understanding the load/unload event. What I have at the moment is a test file. There is one button that loads an external swf (carnival.swf). This seems to work ok as far as i can tell, although I think the way I have hidden the button once the SWF loads is wrong....anyway... On the carnival.swf there would be a "back to main page" button that would simply remove the carnival.swf from the stage and reactivate the button on the main swf, which in the future would have other buttons that would load other swf's on to the stage.

View 7 RepliesIs there a direct way how to turn a negative number to positive using bitwise operations in Actionscript 3? I just think I've read somewhere that it is possible and faster than using Math.abs() or multiplying by -1. Or am I wrong and it was a dream after day long learning about bytes and bitwise operations?
What I saw was that bitwise NOT almost does the trick:
// outputs: 449
trace( ~(-450) );
If anyone find this question and is interested - in 5 million iterations ~(x) + 1 is 50% faster than Math.abs(x).
