I have a var that measures the distance my movieclip moves from its starting postion. the problem comes when it moves left on my stage and the distance var i created becomes negaitive.is there a way to make my var always positive, or find the absolute value of my var? here is my code
powerX = (JnowX - JstartX);the goal is to keep powerX positive
i'd like to negate a number and would like to know if there's a built in method that will convert a negative number to a positive OR a positive into a negative, depending on the number.
i know about Math.abs(), but that only seems to convert negative into positive. is there a method that will do both?
Does flash have any native function (maybe in the math library) to convert a number to positive. ie[code]...

Is there a way to test if a number is negative or positive.I have some clips that position themselves on and off the stage. IF one moves in the other moves out the same direction the other is moving in. This also works the same in reverse. I'm trying to do this by checking the current clips position and see if its a negative or positive number. If its a positive then I can move it onto the stage and move the other off in the same direction. Maybe there is another way of doing this but I thought if I could check its value and see if its negative or positive it would be a start.
View 5 RepliesI am creating a roulette type game that calculates the winning number based on the rotation of the main wheel. I am using if/else statements to determine the winning number based on the rotation. I am tracing the rotation in the output panel. I would like my rotation to go from 0-360, but the output panel traces 0-180 then it starts counting from "-180-0"
The wheel can spin multiple times. how to keep the numbers positive from 0-360 and not have to write my if else to accomodate the negative numbers?
How can I create random numbers (negative and positive) ?Math.random() only produces numbers between 0 and 1.
View 2 RepliesI have a function set up to determine the speed of the mouse, if the mouse is moved to the left it is returned as a variable in a negative number. I also have a function to make a movie clip scroll along, at the moment if you set the speed to 3 it will move to the left. So a positive number will move the movieclip to the left So you can see my predicament because the numbers are opposite, is there way of reversing one of them?
Here it is in short

View 5 RepliesWhen I'd like to know the angle between two vectors, sometimes I get negative values (radian or degree). How do you convert them so I always get positive values? Flash seems to have a strange system for calculating angles. I used the following code for doing this, but sometimes I get negative values.
Code:
public function rangedAngleBetween(otherVector:EuclideanVector):Number {
var firstAngle:Number;
var secondAngle:Number;
var angle:Number;
firstAngle = Math.atan2(otherVector.position.y, otherVector.position.x);

Is there a direct way how to turn a negative number to positive using bitwise operations in Actionscript 3? I just think I've read somewhere that it is possible and faster than using Math.abs() or multiplying by -1. Or am I wrong and it was a dream after day long learning about bytes and bitwise operations?
What I saw was that bitwise NOT almost does the trick:
// outputs: 449
trace( ~(-450) );
If anyone find this question and is interested - in 5 million iterations ~(x) + 1 is 50% faster than Math.abs(x).
I'm having a problem getting a movie clip to Motion Tween from a positive value to a negative value. I have two movie/buttons on my stage. When you click one the other movie Tweens from a y value of 0 to a y value of 400. That works fine. However, when you click the other button, the movie clip should then Tween from a y value of 400 back to a y value of 0. I cannot get this reverse tween to work.
Code:
// code for positive tween
function movePeople(event:MouseEvent):void {
movePlacesTween = new Tween(pageloaderB, "y", Strong.easeOut, 0, 400, 0.5, true);
}
[Code].....
The second tween never reverses. It just stays in place.
I've also tried the same tweens using the y value of pageloaderB... so tweening from pageloaderB.y to pageloaderB.y+400, which works, but the reverse does not -- pageloaderB.y+400 to pageloaderB.y.
why the reverse tween is not functioning?

What i done there i draw a box and made it to movieclip and instance named it hook and created a invisible dot and called it dot. Then I calculated distance from box to the mouse then i took that number and put it in Math.cos command. And finally i made tweener to change box scale depending what my mouse distance from it.So if my mouse is close the box is big , if far - box is small. Ok, I want to know is there another way to do this ? Cuz , i cant think of other way to change arithmetic positive progression(like 3,6,9,12) to negative progression(like 12,9,6,3) than Math.cos command.
I am working on the project where everything is based on the distance from the center of the stage. First I made this fla where flash outputs the x and y distance from the center. First problem is that I want to output distance only in positive numbers.

View 1 RepliesI'm trying to make a preloader for a little flash project that involves re-assembling a load of rectangles to make up a pattern.Idea is that instead of the usual load bar i wanted to make use of this pattern that is relevant to the project and have it rebuild it self with these rectangles flying in from the side. So far I have got the tweening sorted using the tween class and staggered the 42 (yes took a little while, probably an easier way so let me know on that also) rectangles using 'setTimeout' so it releases each 100milliseconds after the one one before it. This probably the wrong way to do it but i wanted to check how it looked and this was the one way i knew how to do it.
I want to make it so that these rectangles fly in a complete the pattern once the loading has finished, but on a fast connection I don't want it to rush the animation but for a slow connection I obviously want it to adjust the release time and maybe even the travel speed to compensate.
I had an idea of maybe working out the percentage loaded divided by 42 and then run an if statement to see if that percentage for that segment had been reached before 100millseconds had passed, if 100 had passed then release the rectangle, if not then hold the rectangle until 100 m/s had passed. Not sure if that is the best way to do but that's why I'm looking for some suggestions from more experienced developers.
