View 1 RepliesI want to curve a dynamic text from a straight line to circular curve (using a slider). I have placed the characters of the string in each textfield created at runtime.
View 3 RepliesI was hoping someone could help me working out some advanced data reformatting. What I'm hoping for is a function where I can input a value along with an array of key positions like so:
function remap(percentage:Number, keypoints:Array) { ...
The array would start with the minimum and end with the maximum point, with nested key points along the way. For example, I would input something like remap(0.25, [0:0,80:50,100:100] ) and the function would 'imagine' a spline curve graph from (0,0)-(100,100) with a key point of (80,50), then return the y value that is 25% along that graph.
I have a curveTo an anchor point and a control point.Then I have a function that will return the x and y of a point along that curve if I give it a number as a percentage of the curve (0 to 1).It looks like this, and works perfectly..
Code:
function drawOnCurve( interval:Number, x0,y0,x1,y1,x2,y2)
{
interval = Math.max( Math.min( 1, interval ), 0 );[code]....
x0,y0 are the start point, x1,y1 the control point and x2,y2 the final anchor point.But... I want to give it a _y value instead of a percentage (interval) and it return where on the curve that would intersect.
i'm loading a database generated xml file that is pretty long(7000 lines). everything seem so work but it gets hung up when i'm trying to create a new xml object.from below if i comment out 3) then i can see the xml displayed in my test text field but with line 3) in there it hangs. it seems like it's hanging trying to create the new XML object. is there a limit to the length the new XML object can be?his wouldn't work?
var xml:XML;
var loader=new URLLoader;
loader.load(new URLRequest(xmlPath));

View 3 RepliesI am making several movie clips that are linked to scroll panes.All of the content is text.I have one movie clip that is a bit longer than the others and if I test the movie a good deal of the text is CUT OFF.This ony happens with the long text movie clip. Is there somewhere I can change the lenght parameters?

I am using the code attached below to make dynamic text curve.
My question is: How can I invert the curve or arc, while making sure that it still reads the same? up to down.
How can I animate a curve being drawn with as3 drawing api.I am not interested in masking it out or other tricks. I am interested in drawing it whith the api.This would be the equivalent, but only a straight line:
var steps:Number = 30;
var currentStep:Number = 0;
var startPoint:Point = new Point(100,100);

I use Loader class to load a picture,such as example.jpg,and I know if I want to realize fade in effect,I can use following code in Event.ENTER_FRAME:sprite.alpha+=0.05.When I run above code,I can get a fade in effect of example.jpg. But the fade in effect is for the whole example.jpg, now I want to fade in the example.jpg with a special curve,such as number 9,the example.jpg fade in along number 9 curve. I guess it shoud have a mathematical model can realize this special fade in effect,anyone could give me the model of fade in along special curve?
View 3 RepliesI try to calculate all the points on a curve.
The curve decided by the width(X on the picture) and height(Y on the picture) properties of a movieclip.The distance between each green point on curve is the same.
what I am trying to do is calculate the position of a point along a curve, what I want to do is create a function where i am able to determine where a point intersects the curve when I provide an X value.I have created a simple diagram to illustrate what I am looking for:So assuming I know the x,y of each black dot, and the x of the red dot, how do I calculate it's y value?
View 2 Repliesposed by some points( an array) with a predefined length( in pixels) from position 0 to X(final) on stage. Now, i modify the points moving on the stage, making new arcs, including the point 0 and x points...So, i need to calculate the length of the new path to make another calcs..

View 1 RepliesI've created a Flex LineChart that shows high and low tide predictions over time. I'm using the LineSeries with form="curve", which produces a nice sinusoidal wave graph, representing water level over time. The X-axis represents time, and the Y-axis represents water level. The only data points I have to work with are high and low tide values, but I would like to figure out how to determine the y-values of arbitrary x-values along the line.[code]
View 2 RepliesI need to detect collision between my bezier curve (drawn using curveTo method) and a object, the curve is dyanamic and hence the equation changes every frame. I am looking for a efficient method to detect collision between curve and the object.

See image attached to explain better than words.
My idea is i need to generate a nice curve between graphical points but in a way that produces smooth curves at runtime.

View 6 RepliesI can't pinpoint or make up a set of calculus to determine the right formula which describes a curve that goes through 3 specific points...I'll try to say it with a more hand-on approach. I have a spaceship which can move vertically,located to the left.The enemies, obviously, arrive from the right. Now, when i click anywhere on the scene,I want a missile/plasma orb/projectile to be shot from the spaceship, but doing more than going in a straight line: imagine 3 points, one at the spaceship, one in front (therefore to the right) of the spaceship (5/10 units in front) and the third at the click location. How do I determine the formula of the curve that goes along these three points?
