ActionScript 2.0 :: Pre-calculate The Perlin Noise Values And Then Loop Through It In An OnEnterFrame
Mar 9, 2007
i got this perlinnoise called function and movieclip.filter = [displacementMapFilter] inside a onEnterFrame and it's eating me at 100 percent. are there any substitutions for making it much less processor intensive? I'd like to show a picture rippling and i'd like to use perlinNoise. Is there a way i can pre-calculate the perlin noise values and then loop through it in an OnEnterFrame
Lately I have been trying to animate the water surface giving it more natural look by use of Perlin noise. But it seems it is very CPU intensive operation. And if I use it along with other animations on the stage which involve lot of movements then it become really difficult for the machine to render the entire scene.
I have an example that I copied out of a book "Actionscript 3.0 Cookbook"here's the error message:TypeError: Error #1009: Cannot access a property or method of a null object reference. at jim.bitmap::Clouds()[C:AS3projectsclassesjimitmapClouds.as:13] at clouds_fla::MainTimeline/frame1()[clouds_fla.MainTimeline::frame1:2]
Is there a way to pre-render a BitmapData.perlinNoise moving animation into a seamless loop of 10-12 frames from which copypixels could be used on the resultant sprite strip to produce fast resuilts?
Reversing the gradient of the displacement does not work. It simply reverses the amount of the effect on the left side so the waves are bigger on the left end, but the waves still move from left to right.
affect the position of a sprite using perlin noise? Looking at this flag example:
[URL]
If you imagined a sprite with say just a circle drawn in it positioned on the top right corner of the flag, is there a way to calculate the change in position to keep it in-sync with the flag corner as that animates? What I'm after is the fluid motion but not the distortion.
I'm trying to replicate an smart filter from Photoshop (CS5) in AS3. Here's what I'm trying to do: I want to have a dark gray background (0x323232 to be specific) with some light, fine grained monochromatic noise on it. I've been mucking around with the perlinNoise method but it's 'too much noise'. Too much contrast. Code: bitmapData.perlinNoise(3, 3, 13, Math.random(), true, true, 7, true); Could anyone point me in the right direction?
I have been trying to create a visual noise pattern using bitmapData.noise, and with help from Rothrock and Kglad have created a working version.I checked with a colleague who is expert on the use of these visual patterns, and he suggested that the change speed is too fast: that the dots (pixels) need to change at just under 400 dots per second for an 800 x 600 stage.With beginner skills in AS3, I am unsure if there is any way to change the script to slow the rate of dot change in the bitmapData.noise function?
As per title said how to calculate the hours and minutes for 2 diferent values eg; value 1 = 9.15 AM value2 = 2.45 PM So I want calculate how many hours and minutes between this 2 values.. 9.15 AM -----> 2.45 PM
I have an equation that needs to calculate variables as it receives them and output the value to a dynamic text field. I have successfully created a function passed values to it but after the first calculation it wont do anything else. [code]...
Which one to use??? What are the performance considerations. If all my movieclips on-stage are running a MovieClip.prototype.onEnterFrame = function() {run initial stuff before setting onEnterFrame=null/undefined... }, will there be performance hits? It's sad that delete onEnterFrame doesn't work unless I delete the prototype enterFrame as well, which would make the clips reinitailise itself again once you declare the enterFrame prototype again (i need to do this since there's more movieclips that end up appearing on-stage, and they need to automatically initialises themselves the moment they appear).
I wish to have only one onEnterFrame loop for my whole movie (made of many mc and layers), how do I set up this onEnterFrame and get all the other functions to use it. At present im using about 5 or so onEnterFrame events within the movie.
im making an image gallery and have a for loop that plots the thumbnail grid. converting it to onEnterFrame so that the thumbnails are created one by one... heres my as:
I'm trying to work this out if anyone can help. I have a function:[code]....when I pause the movieclip set at 30fps the sec,min stop but the frame var keeps running in the onEnterFrame loop. Basically I am trying to count frame by frame in a movieclip, and every 30 frames the frame var will reset to zero.
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.
i have this code that should get a face (eyes, shape, etc) in motion on Mouse Over. The thing is i dont know how to loop this onMouseOver code so it works like an onEnterFrame handler (while onMouseOver).Another way to put it: as long as the mouse stays over the Mclip i want the code to loop. How can i do this?Here is my code:
i'm very new to Flash (although have plenty of experience in Java, C++, PHP, etc). For a University assignment, I am creating a World Cup Guide and i'm creating a countdown to the tournament. I've followed a tutorial and modified it slightly but i'm receiving an error message. The error message is:
I as this working in AS2 and need to update to AS3...shows that AS3 doesn't like sloppy coding. Here's what I need: I pull data from an XML and that works when I put the data into a dynamic text box. However, I can't seem to get the date of birth into a variable. I have some code that calcs age in years but uses a string literal that I thought I could just replace with a variable from my XML...ain't a workin'. Here's the code I have:
I have five buttons on stage and I simply want to trace "1" when I click the first button and trace "2" when I click the second button and so on.I am always getting the last number and cannot figure out, how to store the values.
I have a query regarding assigning values to buttons in a for loop, I will explain:This is a string which I want to assign to a button value via getURL:
I have a movie clip (mc_moviegroup) which is made of a group of many dynamic text fields. I want to loop through the dynamic text field children of mc_moviegroup and pull out their text values in a string. Does a movie clip have a property which gives the number of it's children movieclips?
I have this little loop that creates buttons. My aim is to change value of variable 'thevalue' on everytime button is pressed, first button should give value 0, second 1, third 2 and so on.
Code: for (jo=0; jo<xmlData.firstChild.childNodes.length; jo++) { value1= xmlData.firstChild.childNodes[jo].attributes.value; _root.attachMovie("button", jo, (1000-jo), {_x:20, _y:20+(jo*20)});
