ActionScript 3.0 :: Generate A Random Coordinate Within An Irregular Shaped Movieclip
Feb 3, 2012
I have a series of dots on a world map that depending on certain criteria move from one country to another. At the moment they move to a random point around the country's (mc) centre, as calculated by addind half the width to the x or y coordinate etc. This pressents certain problems such as the centre of the US is actually outside the boundries of the countries borders because of Alaska. Other countries such as the UK have dots floating just off the coast. The dots also cluster coveringing each other up.
Is it posible to generate a random x and y coordinate that is inside the boundries of an irregular shaped mc such as a country. I know that Flash must have these values because of colision detection and mouse overs. I just don't know how you go about accessing them.
What I'm trying to do is hittest two irregularly shaped objects using their alphas and not the bounding box.
The code below hittests two objects named target 1 & target 2. This is not my code, but mine looks exactly alike, except target 1 & target 2 are replaced with my MC's. the thing is, I keep getting an error.At every function line, like the "public static function complexHitTestObject I get an error that says: Expecting right paren before left-bracket. I don't know what this error is caused by, because I can't really see why Flash wants another right paren.
I am looking for a way to get a similar effect as posted in the Adobe forums The current solution is very brute force using about 60 intermediate shapes gradually going from the outer shape towards the inner shape while slightly changing the color each time.
[Code]...
particular problem, I only wanted to have a shape fade into the color of the background so my solution was to draw the image slightly larger than usual and use Flash's blur filter to create the gradient effect. This is suitable only because my background image is a solid color so this won't work for everybody. This is also a very cpu intensive method but is faster than drawing 60 shapes.
I have modified the code from the Interactive Image Panning AS3 version (found here) and I have come to a standstill. If you look at my .fla (link) or the image (link) you can see its not a rectangle but has two of the top corners cut off. So it can't really be panned using the usual method because the corners need to be avoided.I have managed to trace 'white' or 'not white' when the areas i don't want panned are visible but I can't figure out how to get the scrolling to stop! My code is as follows:
I am working on a project, and I'm planning to make a flash lava lamp.I am currently working on the "giving heat to the blobs" part of the project.Currently it looks something like this:Link
[code]...
In the next part of the project I will generate some randomly shaped blobs of liquid and place them in a movie.And then they will find out the amount of yellow inside to get the average "temperature" of the blob, and then the upwards acceleration of the blobs will be determined. So if the blob is relatively hot, it will flow upwards, if it's low, it will flow downwards. As it gets higher, the blob will lose some heat. Touching another blob will exchange some heat and other lava-lamp'ish stuff will happen.Do you think I should do it with pixels? (like above) or do you think I should use "normal flash stuff" ? (By that I mean using movieclips, etc)Is my method of displaying "heat" good? Or could I use another way?
I need some tips, algorithms, code samples, whatever relative to building random shaped close smooth curves, that have no intersections, not many "close to intersect" parts. Pretty much like on the image attached. If there are any algorithms for the same task but allowing intersections - would be great to know too.
attached is an .fla file that has a number of movieclips that move around at random, this part works great. but the movement is only applicable to a rectangle/uniformed area - defined in the action script on frame 1.
PHP Code: function getdistance (x, y, x1, y1) { var run, rise; run = x1-x; rise = y1-
Is there anyway to randomly place a MovieClip/Sprite on an irregularly shaped object?For a rectangle, it seems pretty straightforward (i.e. use Math.random with the range being the coordinates of an object)...but what if say, you would like to avoid placing objects in the center?
im trying to create a random moving line along the x-coordinate that with each cycle will move for a random distance at a random speed. i can generate the ranom distance and speed just fine, but i cant get the speed to apply the movement for then length of the distance. i have tried using a for loop:
The subject pretty much sums it up; I have a bunch of movieclips on the stage, that are already filled with a bitmap pattern in the IDE. Now I need to fill them with another pattern once they are clicked, and I can�t seem to figure out how to do it.This is the closest yet, but i just get a recangle with the new pattern behind my selected mc. I realize that the rectangle comes from the drawRect method (duh) but I cant seem to find something the will allow me to fill the entire movieclip with the new pattern.in District.as

I have 3 square. smallest square s3 is inside s2. s2 is in side s1. each is 10px larger [code]how can I find the coordinate of child in its parent's coordinate system?
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).
I need to generate random numbers between 1 and 20 with a heavy emphasis on the one between 1 and 5, a light emphasis on 5-10, and a low emphasis on 10-20. I don't understand all the fancy probability words and all the stuff they say in the articles I've come across.
Is it possible to generate random number like: gotoAndPlay(Math.ceil(Math.random() *4)); BUT instead of a range have them like .. 40 OR 55 OR 78. Not 0-10 (range) I've got movie clips on certain frames on my main time line, what I would like is to randomly play these.
I need to generate a random number once every time an MC 'dies'. The only thing I can manage is doing it literally once or having it update with a new random number every frame. How do I generate a random number just when I need it?

creating a fucntion in AS 2.0 to generate random number every time get accessed and can be called in front of the XML link from which i am pulling the data from, the purpose is to call the XML always from server to that we never get cached results in swf.
I 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?
I want generate random letter on the stage. Look to this letters and enter this letter on my keyboard. How i can generate it? And i try to generate numbers, but i always see wrong message. Why?
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?
I'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.
public function weightedRandom( Struct options ) { var tempArr = []; for( var o in arguments.options )
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.
