Actionscript 3 :: Limit Angle To Segment
Jun 24, 2010
I need to limit an angle so it fits into a segment. I have drawn and links to a diagram below to better describe what I am after. I am trying to calculate this for a computer program, where I have an angle (slope), and a point (the mouse pointer). The distance does not matter to me, just the angles. If the point is within b1 (green area) then that's fine. But if the point is within b2 or b3 (red or orange) areas, then the angle should snap back to the limit of the green area (along the line s).
The main problem I am having in figuring this out, is snapping the angle to the correct side e.g. If the point is in the red area, then the angle should snap to the angle s on the red side and vice versa. I am also having trouble because s could be any angle, so I am being tripped up because I can't just do something like this:

I have an equation for a parabolic curve intersecting a specified point, in my case where the user clicked on a graph.
// this would typically be mouse coords on the graph
var _target:Point = new Point(100, 50);
public static function plot(x:Number, target:Point):Number{
return (x * x) / target.x * (target.y / target.x);

I have 3 text fields that display weather conditions from the Weather.com XML web service. The 3 text fields need to be visible only during a certain segment of the Flash Video that is set as the application's background. Do I use AS3 to specify visiblity? If so, how do I reference a certain range of frames in which the fields should be visible?

I'm new to Flex, I've tried to do this using a CartesianDataCanvas inside backgroundElements in mxml, then using ActionScript to draw lines on the data canvas using moveTo(x1,y1) and lineTo(x2,y2), which draws a line between (x1,y1) and (x2,y2).
The problem with the above method is the tick mark length is a function of the chart area (which depends on the browser window size).
What I need is a method that:
(1) starts at a data coordinate (e.g. moveTo(x1,y1) works fine for this)
(2) draws a line to a screen coordinate (e.g. lineTo(x_screen, y_screen) where x_screen and y_screen are screen coordinates).
Is there anything that can accomplish this in Flex/AS3?
Alternatively, could I use screen coordinates for both steps above? If so, how to convert between screen and data coordinates? For example, is the upper right corner of the screen always a fixed data coordinate that I could reference is creating such a conversion?
Alternatively, could I save a five-pixel line in Illustrator and simply paste that image in the chart somehow? If so, how to paste it exactly at a data coordinate?

Basically, what annoys me is that when I click a segment to activate the interpolated event, the datatips disappear for it's duration. Whilst this is only half a second, it still detracts from user experience. Is there anything I can do to avoid it??

We're using FMIS 4.5 exclusively for recording streams from webcams via RTMP. We don't have a lot of load currently, maybe a couple hundred videos being recorded every day. Every 1 or 2 days the FMS starts logging "The FLV segment cache is full" and refuses to record anymore until a restart. I've adjusted the cache setting to the max for Linux:I suspect that it's putting everything recorded into the cache, and refuses to record anymore when the cache is full. Why is it doing this? The files are written to disk, why won't the data be evicted from the cache? Am I misunderstanding what's happening?

I'm using Flash CS4 Pro.In Motion Editor, the way that the blur works, it allows you to blur an object on X and/or Y axis.That means you blur horizontaly or/and verticaly.I would like to make a blur motion at another angle, by example 30 degree.

say I have two points: 0,0 & 1,-1If i were to get the angle between these, it should return 45.But the function i have created below returns -45, and If i give it the points 0,0 & 1,1 it returns 45.

I have a carousel built and it works fine, but there is an angle on it that I want to get rid of. When the images move along the carousel, I want them to always stay the same on the X axis. Here is the code, I have tried mangling it in every possible combination, but it is outside my AS3 knowledge on how to get the angle changed.
import mx.utils.Delegate;
var numOfItems:Number;
var radiusX:Number = 1150;
var radiusY:Number = 50;
var centerX:Number = Stage.width / 2;
var centerY:Number = Stage.height / 6;
var speed:Number = 0.002;

how to get angle of mouse its very simple.use this Script (copy and past in your file). A sample file which runs only on CS4 is attached.
//Start............................................. .................................................. .................
// Make a line (o-----------------------) and take its left side as center named 'mcArrow'
mcArrow._x = mcArrow._y =200;

I'm at a bit of a coders block, and I'm sure it's quite simple. I tried using the following:Code:((angle-180)%360) + 180But for angles < 180 degrees, it works just fine, but after that it get's a little funny. I know why it's doing that, I'm just looking for a way to fix it.

I have the xspeed and yspeed of a round ball, xspeed is distance ball moves to the right each frame and yspeed distance ball moves down each frame.I have 3 different gradients of slopes, one is at 15 degrees off the horizontal.How can I calculate the xspeed and yspeed of the ball after a collision with, for instance, the 15 degree slope.

I know 3D rotation is well documented on SO and many other sites, but despite reading countless explanations I still haven't figured out where I'm going wrong. My background is in art and design, not math and programming, and I'm never really certain if my angle of attack (no pun intended) is the right one. Rather than paste a patchwork of my dismal code, I'm including an image describing my problem. What I'd really like is a step-by-step worded breakdown of how to solve it. Pseudo code is useful, but I will learn more if someone will just aim me in the right direction or point out common pitfalls.

I'd like my text to be positioned on a 45 degree angle. Is there an easy way to do that? (In the worst case, I could always make a png out of the text). But, I hope that there's away to do it in Flex. I don't need an animated effect.
var angleText:Text= new Text;
angleText:Text.text = "My text is angled!"
angleText:Text.x= 200;
angleText:Text.y= 300;

I am assuming that I would have to do something with a right angle triangle.

How can change the angle of a premade BevelFilter with AS3.0? (made in the Flash interface, not generated by ActionScript). I tried doing:
ActionScript Code:
myObj.filters[0].angle = 225;
But it doesn't seem to change not even when I trace the value out. When I trace myObj.filters[0] I get returned [object BevelFilter], meaning that the filter does exist.

I have managed to get the app working fine, but i'm tryin to test it out in different angles but everytime i change it seems to go into the same angle.[code]Can somebody tell me why for everytime i changed the value of the degrees, it does not updat the movement of the ball please

I have a code, that draws a horizontal line, then it turns into a slope, and at the end of the slope it draws a circle. Here's a code:
Code:
var xspeed:Number = 1; // defines increments for x of slope
var yspeed:Number = 2; // defines increments for y of slope
var hspeed:Number = 5; // horizontal line increments
[Code]....
Create document 800x700 and put this code into main timeline. Now test movie As you can see, everything works great. But there is a problem. The circle is being drawn at 0 degree angle. But I want the circle to match the angle of the slope, so it looks like the slope and the circle are both at the same angle.
