I have a simple code snippet as follows:
ActionScript Code:
testangle = Math.tan((-stage.mouseY+marker.y)/(stage.mouseX-marker.x));
trace(testangle);
In the swf I simply moved the mouse around the stationary object marker and read the results. For some reason I'm getting crazy values like -20 and 18. Why on earth is that? I thought radians in flash had a range between -PI and PI.
I have an object that rotates based on the mouse positionand I'm trying to count the degrees as it rotates.for example if i rotate 200 degrees cww the degree measurement is 200if i will rotate another 350 degrees cww the degree measurement will be 550now if i rotate 150 cw the measurement will be 400 now.I have this code: (it counts radians, but it is the same idea)p1 = mouse position
PHP Code:
theX theY =
p1.y - 250;radian = -
[code].....
What I've done so far is using your mouse you (click & release) you shoot a ball off in that direction using radians. Now what I'd like to happen is when the ball hits the wall it bounces off in it's reflection angle. Eg. if the ball hits the right-hand-side wall travelling at in a radians of -0.65 it should bounce back in the radians of about -2.5
View 3 RepliesI am not sure 1/maht.tan in flash gives the answer in radians or degree.
anyway, how cna i change? I mean, whats the code? (script)
1 last thing,
I wanna count cot(north / south)
does: 1/math.tan(north , south) does it?
I mean, what comma stands for? - + * / ??
i have one problem. i create one circle and i placed more than one points outer of circle (the points are created dynamic).
View 1 RepliesI have a program which must convert degrees to radians every frame and use this value to change a variable. After a while, I notice that the variable becomes way different than what it should be, because of the slight inaccuracy when converting degrees to radians (I multiply to value by pi/180). I was wondering if there is a more accurate way to convert or maybe a way to use Math.cos() and Math.sin() with degrees.
View 4 RepliesI am currently learning some trigonometry tome with my actionscript...In AS I am aware that angles need to be converted from degrees to radians to use certain Math properties, such as Math.sin...etcHere is my code to convert degrees to radians...
ActionScript Code:

var radians:Number = degrees * Math.PI / 180;

I am trying to create a dynamic scrolling list in Flash AS3. When I create a list, I set it to be an initial length. Later, I add more objects to the list which is outside of the original size of the list. I want to be able to scroll down the list and see all the objects. My scrollbar just moves the list's y position. However, every object that is drawn outside the original list size is not shown when I run the program and scroll. I have a list object which has the function below when I need to add content to the list. When I initialize the list, I give it an initial height and width which I use to create a mask.
public function AddPlayers(pPlayers:Array, pScrollBar:ScrollBar):void {
var player:Player;
trace("happened again");
for (var i:int = 0; i < pPlayers.length; i++)
player = pPlayers[i];

If I populate a vertex-buffer by using the byte-array method:
//Example: var ba:ByteArray = new ByteArray();
//Write vertex #0:
ba.writeFloat(-.5);
ba.writeFloat(-.5);
ba.writeUnsignedInt(0);

What is the range of values possible (0 to 255? 0.0 to 1.0? etc.) for the Vertex attribute's field (in this case, va0.x, va0.y, va0.z, va0.w)? Does it vary between which data-type is written to the ByteArray object (writeFloat vs. writeUnsignedInt)?
really great job done in the forum This is my first thread here, and i would like to ask how can someone produce a random number within a complex range.In my case i want to produce a random number in the range [0,90]OR[270,359] and i can't find the way to do this using Math.random . I looked on the internet but in most cases a simple range is used like (2,40) or [4,50] etc.

View 4 RepliesIn my application I'm using a custom embedded font for English (Helvetica New) which does not contain characters (glyphs) for chinese unicode range. In the application, wherver chinese characters are avaiable they are not displayed (suppressed) since they are missing in the custom embedded font. How can I make the flash player to use a fallback system font for the missing characters? And the fallback should be for the missing characters alone. For the Engligh characters it should use the embedded font.
View 1 RepliesThis code below works, but I'd like to modify it so that if my dragged item passes over a region in the x coordinates. So if I pass the dragged item over the range of 600 - 700 then it would play the frame labelled "square", and when it passes out of that region, go back to play the frame labelled "circle". So realy I'm asking how can I modify the <=600 to instead 600 to 700, and else refer to circle.
if (me.x <=600){
me.gotoAndStop("Square")
} else if (me.x>= 700){
me.gotoAndStop("Circle")
}
I've got a variable called coins which contains the amount of coins you have.I've also got a movieclip called customer_marker_mc which I want to change color depending how much coins you've got...I want 100 (or more) - 91 to give one color and 90 - 81 another and so on.[code]...
View 6 RepliesI'd like to check if a mc's _x and _y properties are between a certain range, but can't find out how to. Now that I'm typing this (I can't check it in Flash right now at the moment), I'm thinking if this will work:
let's say the mc is called mcMyMovie and it has to be between 90 & 100 (both for x and y)
if(mcMyMovie._x =< 100 && mcMyMovie._x =>90 && mcMyMovie._y =<100 && mcMyMovie._y =>90) {
}
Would this work or is there a shorter way to write this down in code ? In maths I'd write something like 90 < mcMyMovie._x <100.

The situation is an interactive text book using the Webkit view of Adobe Air. I have static (built-in) html content that the user can highlight and bookmark (annotate). This mechanism all works, but I need to be able to store and restore these annotations. I would rather not store a modified version of the DOM, but rather use the static version then reapply the users annotations that I am storing in a SQLite DB along with other needed metadata. DOM manipulation is pretty new for me, and so far my attempts to serialize a DOM::range have failed. What I realized though is that I really seem to only need the start and end containers and the start and end offsets. Then I can recreate the range with document.createRange().

it is important that the color replacement blends well and does not have banding/dithering.
