I wish to have a function that will take as input a radius value and a magnitude value.
It will return firstly a point (x,y) and also secondly a direction, (vx,vy) which will have a certain magnitude(speed).
The point returned will be a random point within the radius value and the direction will be a a (vx,xy) that moves the point perpendicular to the line segment (x,y) ->(centrepoint).
I'm not a genius in geometry, I'd like to find a point in as3 with the radius and a angle but I don't remember the rule, I know this should be simple!
View 3 RepliesI have a movieclip called view_mc and a button btn_rotate.
I want when the user click and drag btn_rotate button, he can rotate the view_mc movieclip clockwise and anti-clockwise.
I have written a code, but it only rotates the movieclip in clockwise direction:
stage.addEventListener(MouseEvent.MOUSE_DOWN, on_stage_down);
stage.addEventListener(MouseEvent.MOUSE_UP, on_stage_up);
function on_stage_down(e:MouseEvent):void

I'm writing a class for an instrment and one of the knobs has "snapping" values at X degrees.I have the code to make the knob snap to the set degrees,but I'm having trouble getting it to determine whether it was rotated clockwise or counter-clockwise.Here is the function that makes it rotate and "snap" The majority of the problem is because of the 0/360 and negative values that Flash has when it rotates..
In the function:
the _baseMovieClip is the clip that contains a graphic to rotate and "snap" to the degrees.
the _clipToRotate is a movie clip that actually displays the rotation
the _startAngle is the angle the user clicked on the button that triggers rotation
the _rotateObj is a sprite that is drawn when they click that I make visible to show the actual rotation when I'm debugging
the _snapLock is the degrees the knob shold rotate to (10, 15, 30, etc)

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 know some basic trig. but how do i find an angle from an anchor point and a moving point?
adjecent = _root.anchor._x-_root._xmouse;
opposite = _root.anchor._y-_root._ymouse;
hypotenuse = ((adjacent ^ 2)+(opposite ^ 2)) ^ 0.5;
1) what value is seeded to Math.random() to generate the random number?
View 2 RepliesI've got two concentric circles with their centers at (centerX,centerY). The inner circle has a radius of 100 and the outer circle has a radius of 400. If take a point on the circumference of the inner circle, I can draw a line from the center to that point. Let's call that point x1,y1). I now want to continue that radius out to the outer concentric circle and calculate the position of that outer point (x2,y2).
I'm adding a 3px 'dot' just to show where x1, y1 is on the screen. (Subquestion: I can't see it...not sure why.)This is what I'm trying:
var x1:Number = 100;
var y1:Number = 50;
var x2:Number;[code].............
I have a simple game going now with a character running forward and I have to jump and duck under barriers. I was able to make it all work so that one of my three random barriers I made comes at a random time at you. However, I don't know how to make it so that multiple barriers come at you. I feel I need some sort of loop. How should I alter the code I have already? This is on one of the barrier moveclips, the first part sets the platform and position to come at you and the second part moves that part towards you. P.s. this is in cs4.

I simply want to generate a series random characters. Ideally, I'd like to do that for a set of characters ending in a pre-determined word, but I'm sticking to the simple task of generating a series of random characters that can be visually seen changing in time (say for 1 second).

View 14 RepliesI have this hyperlink, but I want the program to look through the hyperlinked page and pick out random words within a certain perameter. So like, it has to have a noun, verb, and pretty much end up a normal sentence that is completely out of context. Something like, "The doppler effect enjoys pine needles in the cornfield."
Is it even possible to get that? Can you even generate random string off a hyperlink? Can actionscript even browse through a hyperlinked file?

generate random text with the click of a button. I have followed the kirupa.com tutorial for 'loading random quotes' but I am still getting a few undesirables. Firstly, I am generating an 'undefined' result occasionally. (Even with the example text from the tutorial). I have 5 quotes as per the example, but still get undefined as a result from time to time. Also, how would I go about altering the code so the same quote wasn't generated immediately after itself?
View 3 RepliesI'm trying to devise a (good) way to choose a random number from a range of possible numbers where each number in the range is given a weight. To put it simply: given the range of numbers (0,1,2) choose a number where 0 has an 80% probability of being selected, 1 has a 10% chance and 2 has a 10% chance.
It's been about 8 years since my college stats class, so you can imagine the proper formula for this escapes me at the moment.
Here's the 'cheap and dirty' method that I came up with. This solution uses ColdFusion. Yours may use whatever language you'd like. I'm a programmer, I think I can handle porting it. Ultimately my solution needs to be in Groovy - I wrote this one in ColdFusion because it's easy to quickly write/test in CF.

var tempArr = [];

I am trying to generate a random number of particles (say between 1 and 4) per second, which would float up the screen from the bottom at a random X value (width is 1280 px). These particles should be a random size (say between 2 and 5 px in diameter) and a random opacity (say between 20 and 50%).
and all of this should be going on in the background while the rest of the flash actions are taking place.
How would I do this, I have been experimenting but have had very little success. It is something that I could easily do in after effects however I would like to keep file size small and allow for continuous uninterupted play.
