ActionScript 3.0 :: Maths: Exponential Value Via Loop?
Dec 27, 2010
To create a sort of thick-pixel gradient shadow, I've got a simple loop which creates a new 200x5 pixel Shape (rectangle) with each iteration, assigning an alpha value and y value that changes relative to the loop's iteration.
Code:
var upperShadow:Shape = new Shape();
for (var k:int=0; k<10; k++) {
shadowAlpha = (1-(k/10))*.5;
trace(shadowAlpha); // traces .5, .45, .4, .35, .3, .25, .2, .15, .1, .05
[code]....
This creates a simple linear gradient since the alpha value changes linearly, but how would I go about creating some sort of exponential/logarithmic/cubic/circular value for the alpha, so that it falls off differently?
Are there a set of common equations that people use for this sort of thing, similar to the simple (1-(k/10))*.5 I use for the linear change from .5 to 0 in ten .5 increments?
I've built a slider which also contains an input textfield. the slider can be dragged and it's value will be updated in the textfield. a user can also enter a value in the textfield which will then be reflected in the slider. All is fine thusfar. However, I'd like to figure out how to give the slider an exponential scale instead of a linear one. Say the slider has a minimum value of 0 and a max of 100. When the slider is dragged halfway then using a linear scale it's value would ofcourse be 0.5 * 100 = 50. To calculate the value for the exponential scale I use
I have a square grid with 100 grid squares in it.I want the cursor to display its grid position.Does Flash plot the position based on pixels - ie would my grid square have to be 100x100px or a multiple of that eg 200x200px? Or could it calculate the position no matter what size the square was? eg 186x186px ?
I have an app that was actually written for me. It's a multiple choice quiz basically where a question comes up and there are 4 answers. HOWEVER the answer always seems to be 80% on the same answer ie: BUTTON ONE out of the four. BILLIANT random function I don't think.Would this be a better answer formula to use?
function randomBetween(a:Number, b:Number):Number { return (a + Math.floor(Math.random()*(b-a+1)));}
I have some code that looks like this: ActionScript Code: level_btn.x = 50 + (i - 1) % 10 * 50; It sets the x location of my level button. But this is in a for loop (that's what the 'i' is for.) I run it and everything works perfectly, as it should, not a single problem. Then I press the auto format button in the flash actionscript editor. (It's the button that adds all of the ; to the end of each line and other stuff)
Well that changes my code to this: ActionScript Code: level_btn.x = 50 + i - 1 % 10 * 50; thinking it's done me a favour but it hasn't. It's got rid of the brackets so it won't do the maths functions in the correct order. I've tried adding more brackets in places and other stuff but I just don't know how to fix it. It's annoying because every time I press the auto format button I have to add the brackets in again.
i want to finish it in the end! i have this code which generated 20 stars and an ai player collects all of them (going for the one which is closest to it). This code was courtesy of -lauri... the code was
what i have currently is a player who moves around with the arrow keys collecting stars which appear at random moments... i wanted to make it so that the ai can also collect these stars and i am pretty sure that the code for that would be linked to what.
im working on a maths style jigsaw, and ive come across a problem of sorts, ive set random1_txt.text to 1 and random1_txt.text to 2 for testing, basically i want to randomise two textfields between 1 and 10, and also randomise the sign between either a - or a +
the answer can be computed by flash, now what i need it to do is stop on the frame number of the answer in answer_mc, these frames contain graphics of all numbers 1-20 in alpha format, this is so that the answer is in place, now the user can drag and drop movieclips into the answer box, and receive a correct or incorrect response
im at a loss on how to do this, i havent gotten around to randomising the sign as of yet i need to do more research but the general idea is as above
Code: var startX:Number; //start of draggable piece var startY:Number; random1_txt.text = "1"
In the scene there is a star and an AI player.what equation would take the AI player on the most direct route to the star...i.e guide it into the path of the star...just to make things clear, the star is static and the ai plaer is controlled by the computer. i think you have to make two variables distx and disty and use some sort of trigonometry on them but i'm not entirely sure on how to go along doing this.
I have an application performing a simple calculation of adding and subtracting a amout to/from a balance amount.The problem is that every thing works fine except that when i remove the lkast amout from the balance ie: 15.25 -15.25 suppose i get something like -5.32907051820075e-15
I am trying to create a script, where the user inputs a maths equation (something simple like 5 + 2 * 10), I have managed to break down the text into an array and have the numbers in one array and the symbols in another, I wanted the computer to then work it out, however I cant seem to think of how to do this and the methods that I have tried have failed.there is one dynamic box and the value of that is then broken down by an array split(" "), however this leaves the values in an array and it is percieved as a string not a number and so when i try to work it outit just displays 5 * 10, how would i get it to work that out?
Code: knob_mc.addEventListener(MouseEvent.MOUSE_DOWN,turn); stage.addEventListener(MouseEvent.MOUSE_UP,endTurn ); function turn(e:Event):void[code].....
This is the code I'm using to move a knob the challenge is when i click on the knob it turns 90 either left or right depending where i click, I'd like it to stay still until I turn the knob, and second how do I get the angle in whole numbers??
i'm trying to do an infinate loop for my m.clip.the looping part does not want to loop...it loops back to my firrst frame even though there are two same picture in the movie clip.....here's a sample of what i use for the infinate loop script..
I have need of loops / nested loops that pick different figures depending on where you are in the loop. The whole function needs to run through 'ml' times. 'ml' is a dynamic figure. Loop 1 = While the loop is within the first 12 iterations, 'exconemp' must equal 100. For iterations 13 - 24, 'exconemp' must equal 102.5, for 25 - 36 it will be 105.06, for 37 - 48 it will be 107.69. This needs to change every 12th iteration until it has reached 'ml'. The calculation takes the value of the previous 'exconemp' and then multiplies that by 0.025.
Loop 2 = While the loop is within the first 120 iterations, 'abc' must equal 0.015 and any further iterations must use 0.01. This must also work in a way to figure out whether 'ml' is higher or lower than 120 and work accordingly. My main issue is this - how do I get the loops to run through as this: While the iteration is < 12, do this, THEN take the final figure (12th iteration) and start on 13 - 24, do this THEN etc etc. How do I produce a THEN statement? I can get the code to pick up the final values, but not change along the way.
basically I need a loop within a loop to compare two different arrays in my actionscript3 lottery game. I have attempted the loop but I cannot seem to get it to work ...
[Code]....
So basically within this code check_win is a button. Once the button is clicked it runs the loop. It is meant to take an instance of matches which contains 6 properties and loop until index is greater than matches. According to my output this is happening but the second loop doesn't appear to do anything.
How do i word a for loop to make it loop through multiple arrays?I want 1 for loop to loop through multiple arrays in order to move/alter objects.I want to keep the arrays separate.
ActionScript Code: characters = new Array(); characters[0] = male;
I'm trying to make a matching pairs game. First of all I'm making all the tiles, using a loop inside a loop. How do I get the ID of an item inside that loop? My code looks like follow:
Code: var matches:Array=new Array(1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8); makeTiles(); function makeTiles() {
the loop starts at 0 and not 1 so the loop ends at 6 does any one know how to resolve this issue?? its so that what ever number dayVal is it will be rounded up to a number that is Divisble by 7 .
Basically, I have data organized by date in an XML file. I'm trying to make a website application that will allow the user to click on a date (in a text field) to see another textfield populate with all the data under that particular date. So far, all the information loads into the textboxes at the same time. How can I get it to only load information under a particular date when somebody clicks on that date?
Before I started this project, I was convinced I could do this by manipulating the [j] (see code below) in the myFunc2 function. Currently, it's set up to increment blank_mc._y by whatever value is returned by [j]. But for some reason this doesn't work. I feel that if I could atleas get this part to work - I could probably do the rest.
AS code:
Code: function loadXML(loaded) { if (loaded) { var nodes = this.firstChild;
wondering if anyone knows if its possible to have a pause within a 'for loop' before it runs through the next loop? heres the script i've built up so far, i'm running off other variables and arrays to pull in the logos and the animating in is working fine except that they all run in at the same time, basically what i want is that they would run one after the other with a 5 second gap between them..[code]so i did that and put wait(delay); after the var boxcounter=2; in each of the If statements.. but no luck... can anyone shed any light? or suggest a way it get it to hold for a few seconds before running though the loop again? or am i going about this in completely the wrong way??!
I have published my intro to my website I checked "Loop" and unchecked "Loop" under the Flash section of publishing no matter which I it continues to loop and not go to my website. This is the action I am using:[URL]...
I have a variable in a loop that i want to access in a function outside of the loop. However the variable gets deleted when the loop is closed so no longer exists when i call in the function.here is the code; i'm trying to access the variable picHeight from within the scroll function
I'm trying to synchronize external subtitles with my custom video player - Not FLVPlayback.Subtitles are in XML object from 0 - 12.I created a Timer that is checking when the subtitle 0 should be displayed according to playback time.I want to reach that after subtitle 0 disappear the next subtitle 1 will be checked when should be displayed.So all I want is 0 + 1But it is Timer and the result after Subtitle 0 disappear is 0+1+1+1+1+1+1+1+1+1+1+1 ad infinity And thats too many as I only want once add 1.
