ActionScript 2.0 :: Advanced Random Movement - Smooth?
Sep 1, 2003
Let me explain - on my upcoming website (in a year, maybe?) i'll have some sort of cartoon character walking above my contents - and I want his charcter to be smooth and actionscripted. However his movements should be done as a curved motion path would, but random.Now random movement will either: a) get you to one point and then to the other, but making a sharp turn or b) have no coordination in movement (good for making a bee fly but not for anything else).here's what im trying to do:
transform straight lines movement (random):
to something smoother
something inside me tells me it's got something to do with cos and sin functions but I've no idea how to make that work.And I don't want to do motion path because I need to do actions that rule that out.

[URL] how to move an MC using the keyboard. However, I'm looking to do a motion that is a bit more complicated than that - and I'm somewhat stumped. (Yup, Im new to actionscripting)
I'd like to be able to move the MC 100 pixels (and that part I've figured out), but I need the motion to be smooth - with inertia. I searched and searched, and this is a link I found that looked useful in demonstrating the effect:
[URL]
Click the 4th example - 'Inertia, Single plane of movement'Now, instead of having the _xmouse determine the position, I want to hit the 'forward/backward' keys on the keyboard, and make it hop smoothly forward or backward a 100 pixels. Im just confused where to add what, and I am continuing to work on it. This is being programmed in Flash MX 2004.

I've been searching it everywhere, but couldn't find anything in the net. I want to make smooth line movement. I've tried to create motion, but line just moves, and I want it to move smoothly according to the path. What I want to achieve can be seen [URL].. that's what I did so far - made movement out of several broken lines

There are two basic ways of panning a view in Flash. One is to move the display object (and use a mask if necessary). The other is to use scrollrect. Today I noticed a small, but annoying effect of scrollrect. Scrollrect's can't have true Numeric positions-- they are automatically snapped to the nearest pixel.
When moving at very slow speeds, the effect is noticeable. In this example you can switch between two modes of panning, sprite movement with mask and scrollrect:
http://lab.wx3.com/scrolltest/ (view source enabled).
In the default mode, the circles move smoothly.
In scrollrect mode, the circles seem to stutter because the scrollrect is snapping to the nearest pixel.found a way to make a scrollrect move smoothly at slow speeds?

I am trying to move an object on keypress. so i am doing
if(keyboardevent.keycode == keycode)
{
code to move;
}
this works perfectly fine, but when i keep the key pressed for a couple of seconds, the motion is not smooth. for the first second the object gets stuck there, and then moves smoothly. same thing happens when i change the key. basically, it is taking time to read the first key event.
why is it so? i dont want this 1 second delay. i want the object motion to be fluent, as i am making a time critical game.

I have the following script in both frame 1 and 2 to let a movieclip move from right to left on the stage:
Code:
speed =-5
name._x += speed
if (name._x<-500) {
name._x = 250;
}
And the clip is indeed moving from right to left on the stage and when it reaches _x -550 it is going back to it's starting position _x 250 only the movement isn't smooth at all. What should I do to make the movement more smooth or should I use a completely different script?

I want to make a smooth movement when i click on anywhere in my seek bar. So i come up with an tween which is below. I have a mask called tbMask which is stays beside timeBar.
ActionScript Code:
Code:
new mx.transitions.Tween(timeBar, "_xscale", mx.transitions.easing.None.easeOut, 0 , tbMask._xmouse, 2, true);
So basically this would make timebar stretch to tBmask's _xmouse which has same x (170). But it dont! It exceeds about 50% where i clicked and go back to _xmouse.
Far from this problem, the anothers are; I call this swf from my main swf. Tween function works when i try to view my main.swf but it dont work when i call player.swf from browser.

I used to use AS 2.0 but I've finally made the switch to 3.0. I am majoring in CS so I am familiar with basic/intermediate concepts, but I am very unfamiliar with 3.0. I have a movieclip controlled by arrow keys, however the movement is still slightly choppy. Everything is uploaded below, the code I note here is the code for movement located within the .as file.
Code:
package {
import flash.display.MovieClip;
import flash.display.Stage;
import flash.events.KeyboardEvent;

I have 6 buttons aligned horizontally. When I press one button, I want all of the buttons to move to different _X positions with easing that would be specified in an array or in a variable. I'm looking for the easiest code. I had the code and a fla. for this a few years ago when I was deep into Flash, mastering actionscript. Now, it's like starting over.
Also, can anyone assist me with a similar, more advanced code? It's the same as above, but when one presses a button, that button pressed would move to a specified _X position, and the button that was previously in that _X position would get back in line, to the far left of all the buttons...

And I want it to randomly wave like if it was a hair in the wind, or like a snake moving, or even like a flame waving.Is there any way of doing it with actionscript?Is it also possible to make react to the cursor? When I pass through it with the mouse it moves, like if I just touched it.

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.

Im animating an around in 3d space with papervision and Id like to make the curves of the animation nice and smooth, if I put random values into the xyz and bezier values the turns are quite weird and erratic. Does anyone know of a way I can animate something around in smooth curves, but not have to create specific values for the tween?

Since i upgraded to Flashplayer 9.0.124.0 i've noticed that using textures on 3D Objects via the beginBitmapFill method and setting the smooth attribute to 'true' causes the player to hang a few milliseconds at random. Setting smooth to 'false', the player runs without any hang. I tested this on different machines. An upgrade to player 10 beta didn't cure the symptoms but the hangs appear less in time. Has anyone else such problems or an idea what is going on?

i have this code i found that smoothly moves a box left or right on the screen based on using the left or right arrow keys. i want to use this smooth code but adjust it so on enterframe, the box would move from point a (say 0,120) to point b (0,240) and stop there.no keys used, just working based on entering the frame.how to modify the code below?

i've applied the following script to a movieclip to change its 'y' coordinate randomly at run time and it works fine but i'm also trying to control the maximum 'top' and maximum bottom 'y' movement for which the value should be: top = 40 and bottom = 400. so it only displays randomly between 40 to 400 'y' coordinate. could you tell me how can i implement this in the following script?
onClipEvent (enterFrame) {
_x -= 4;

I've been trying to simply get random movement on a MC on my stage.
Most of the tutorials I come across deliver jittery motion, not smooth eased motion.
Also, I'm trying this script found here: [URL]
The random motion looks great! .... but I can't stop the MC from moving to the top left of my stage. The script isn't setup to restrict the motion within a given area on the stage. I tried modifying it, got nowhere!

I wanted to built an enemy that is able to move on stage randomly in xposition and perhaps able to detect my character within the detectable zone and chase after me.. but currently I just wanted to make the enemy move randomly in x-position for starter.
It is my first time making and enemy with AI, but I'm just wasn't sure where to begin, I have used a fairy easy script to animated the movieclip in the beginning but got stucks whenever it reaches 960 or below 0 of the stage
addEventListener(Event.ENTER_FRAME,initGames);
function initGames(e:Event):void{
moveEnemy();

I'm trying to achieve random motion of my movie clips limited from stage left to stage right. I've read the following tutorials:

both are helpful. However, I don't want mouse position to affect anything (as it does in the 'continuous movement' tutorial). The 'random motion' code is pretty close...if I just knew what part of the code to modify to limit motion from left to right.

i want to make a movement. An object has to come from behind an object and go back again.The interval between each time the object appears has to be random.i was trting to maken something with the setTimer() function, and a random. The random gives a var.This var i would use as time for the object appears in combination with the setTimer().i can't come up with a decent code that would work.Where do i need to define the start vars, adn where do i define the random script.

My knowledge of actionscript is basic, at best. I'm trying to make some animations move randomly by following a very helpful tutorial posted on this site [URL].. And everything was going so well until I tried to use my own initiative to limit the width and height of the movement. This is when I realised that I haven't got a clue what I am doing!

I'm trying to move a series of dots (mc used as linkage: "Dot") within a frame to random targets, with the movement activated by onRollOver. This part I have working fine. The part I'm having difficulty with is getting the objects to have target coordinates to move randomly, except rounded to the nearest 12 pixels. Here's the relevant code:
