ActionScript 3.0 :: Test For Negative Or Positive Numbers?
Nov 9, 2009Is 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.

May 12, 2009I 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?

Jul 9, 2009I 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?

ActionScript 3.0 :: Negative Numbers As Target-value Of A Tween
Dec 13, 2010I'm not sure if if this has occurred to anyone before.... I'm using the built in tween-class of flash (cs4). In my script I try to display a notification-box using a slide-in effect: var slideIn = new Tween(this.warningBox, "width", Regular.easeOut, 0, 150, 0.5, true); This works. The box is invisible at start and then builds up like a flag unrolling from left to right. However, what I really want to do is sliding it in from right to left. So I tried to do this: var slideIn = new Tween(this.warningBox, "width", Regular.easeOut, 0, -150, 0.5, true); Obviously, I modified the warningbox so the pivot point is to the top right, but it still won't work. It seems the endvalue must not be a negative number. Can anyone confirm this, or have I missed something?

ActionScript 2.0 :: Negative Numbers - Counting Down From 9999 Instead Of Beginning At -0001?
Jan 30, 2011I am currently taking a value from another source and splitting it into Thousands / Hundreds / Tens / Ones to drive MC's containing images of numbers. Originally I was using this external value to drive a dynamic text box and that was absolutely fine. When the external value went below zero the dynamic text box reflected this and started counting downwards ie 0 -1, -2, -3 ......-100 etc etc. However with the system I am now trying to implement when the external value goes below zero my counters show 9999 and count down towards zero.
For example the actual value of the external value = -32 but my counter system is showing 968. Always the sum of the actual value and my counter value = 1000. So again maybe actual value is -160 but my counter shows 840.Below is the section of the script splitting the external value (roundelevation) into 1000/100/10/1's
Code:
roundelevation = Math.round(scaledelevationMils);
EliThous = Math.floor(roundelevation / 1000);
EliHund = Math.floor(roundelevation / 100) - 10 * EliThous;
EliTen = Math.floor(roundelevation / 10) - 100 * EliThous - 10 * EliHund;
EliOne = Math.floor(roundelevation) - 1000 * EliThous - 100 * EliHund - 10 * EliTen;
I am using these variables (EliThous / Elihund) etc to move to different frames of mc's inside the Mc's each frame is an image of a number.It works absolutely perfectly when the external value is above zero and my counter is counting upwards / downwards. However as soon as it begins having to deal with the external value being a negative number it begins counting down from 9999 instead of beginning at -0001 and counting -0002.how to make this work when dealing with a negative input value and I really don't want to have to go back to using the font and dynamic text box approach.

Flash :: Forcing A Negative Bottom Margin?
Aug 4, 2011I have an .swf navigation carousel that is 650 pixels high, the bottom 200 pixels being reserved for the reflection of the carousel. The reflection is very subtle and is not considered important information, so we would like to remove vertical scrollbars when the window is high enough to fit the topmost 450 pixels, but not the reflection.
I tried to accomplish this by setting a margin-bottom: -200px to the flash <object> but this only made the container's height shrink 200 pixels, causing the background pattern to cut before the bottom of the page.the Flash itself is still taking up 650 pixels.
Is there some "proper" fix to this, other than hiding/showing the scrollbars actively using javascript?

ActionScript 3.0 :: Flash StartDrag Setting Negative Bounds?

minimum x before I get whitespace: -1536
minimum y before I get whitespace: -1152
maximum x before I get whitespace: 0
maximum y before I get whitespace: 0
I have tried this:
Code:
var mcBounds = new Rectangle(-1536, -1152, 0, 0);
mc.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
mc.addEventListener(MouseEvent.MOUSE_UP, mouseUpHandler);
[code]...
But it doesn't drag at all...when I try it just moves it to it's maximum position and stays there.Is it because the rectangle can't have negative values?

Nov 11, 2010I noticed this when testing a (physics) project where particles are moved across the screen by adding their velocity to their x/y coordinates.[code]The problem is that the sprite gets moved with steps of approx one twip (0.05 pixel) even at ridiculously low values of vx/vy like "-6.0277093305460 02e- 10". This only happens when the amounts that get added to the x/y coordinates (vx/vy in this case) are negative. No problem with positive numbers. The creeping stops when the square hits a stage edge.

View 4 RepliesActionscript 3 :: Fastest Method To Find A Complex Type In A List
Apr 12, 2011I need to know the best method to find an item inside a list (Vector, Array, Dictionary, whatever is faster) of complex type (extensions of Objects and Sprites). I've used "Needle in Haystack" method, but it seems that it isn't fast enough.
E.g. Suppose that I have a collection of Sprites (a pool, in fact). Each sprite will be added to the stage and perform some action. After that, it will die. I don't want to pay the cost to dispose it (garbage collect) and create another (new) one every time so I'll keep the dead sprites in a collection.
Sometimes times I'll call a method that will add a sprite to the stage. This sprite can be a old one, if it is already dead, or a new one, if the pool don't have any free sprite.
One of the scenarios that pushed me to this question was a Particle System. A "head" particle leaving a "trail" of particles every frame and exploding into a flashy multitude of particles... Every frame...
Some times this counts up to 50.000 PNGs with motion, rotation, alpha, event dispatching, scale, etc... But, this is JUST ONE scenario...
At the moment I'm trying to use a Object Pool with a Linked List... Hopes that it will be faster that running a whole Array/Vector or create new instances every frame an let them dye with Garbage Collection.
ActionScript 3.0 :: Fastest Method Of Determining If A Triangle Is Encompassed By Smaller Grid Squares?
Jul 19, 2010I've got my 3D sphere to triangle collision detection working now, but I need an efficient method of adding the triangles to the broadphase grid.
This is easy enough if the triangles are smaller than the grid nodes, however - especially given the polycounts I'm working with - it's going to be fairly frequent that a triangle is significantly larger than the grid nodes.
Here's an example.See the yellow polygon? Just adding it the grid nodes by it's vertices results in it NOT being added to 4 grid nodes that it does reside in.
My first thought is repeatedly casting rays along one of the edges from the normal of the edge until you find the intersection point with one of the other edges, of course checking for intersections with the grid edges until you reach the destination intersection with one of the other edges of the triangle. This would work, but is not particularly fast.
Although these triangles aren't being added/removed in real time, only when building the level, when constructing a level with say 100,000 polygons total, I obviously want it to be processed as quickly as possible.

I want to generate a variable number of random numbers less than 16 with no duplicate numbers
Ive posted the fla, and what i'm doing is generating a random number and putting it into an array then using a for loop to cycle through the array for each new random number to check if its already there. if it is, then i want to regenerate that number.
if you test the fla you'll see that all i get in my array is some lovely zero's and i sort of know why this is, but don't know how to stop it.
