ActionScript 3.0 :: Quick Calculation Based On The Mouse Position?
Jun 16, 2009
I have am wanting to do a quick calculation based on the mouse position.here is what I am trying to do.I have an item the site on the stage
stage.width = 400;
object.width = 900;
object.x needs to be at its most -900 and at its least -225.
and based on the mouse position on the stage object will scroll within these bounds.I have all the functional done but just need to know the basic equation to find these points.
I am replacing the mouse pointer with a custom graphic in an .swf that takes up part of a web page (.swf stage is about 350px wide, total layout is about 1000px). My code is all working fine, except that, if you move the mouse fairly quickly -- as you might do to get from a point on the .swf to the opposite side of a large monitor -- the .swf loses track of the mouse, and thinks that the ._xmouse/._ymouse values are still the same as the last point that that Flash saw the mouse, which is usually somewhere in the middle of the stage, thus "orphaning" the custom cursor. If I have a setInterval or something tracing the mouse position, the .swf still thinks that the mouse is sitting on top of it, even though the cursor is actually far away somewhere else. hitTest also still returns true as though the mouse was there (as you might expect, given that it's based on _xmouse/_ymouse).
The workaround/hack I have going now is that, once the pointer switches over to the custom cursor, it starts a setInterval, and then if the mouse appears not to move for a few seconds, it reverts back to the default cursor (i.e., Mouse.show). Obviously, this is not optimal, because that means that the custom cursor disappears if you don't move the mouse for a second or two, and it doesn't really solve the problem anyway because it still looks like the custom cursor gets stuck for a second when you move too fast.
So I'm working on my portfolio and I got this problem. The code posted scrolls the sprite "cellContainer" based on the position of stage.mouseY. Perfect.Problem is that I want stage.mouseY to equal the entire cellContainer height. Kind of like how a small tablet equals a huge monitor. So when stage.mouseY = 0,cellContainer.y = 0 and when stage.mouseY = stage.stageHeight, cellContainer.y = stage.stageHeight - cellContainer.height. Right now, it scrolls, but it takes a while to scroll throught the entire height of cellContainer. I want it to be proportional to stage.mouseY.

I'm doing an online advertising format (728x90 leaderboard). I have embedded a video into the flash file which covers 1/3 of the format (242x90).What i need to do is seek this video from 0% to 100% based on the mouse position over this area (242x90). I'm guessing it would be easier if i created a button over the video which is 242x90 but i would still be looking for the code that seeks the video based on the mouse position over the button.
I have created a document 600x300 filled with buttons for a rollover effect. I want to be able to play sounds dependant on the x and y position of the mouse without having to use objects that interfere with the buttons.
I'm trying to make a faux 3D rotation animation where if the user mouses to the right the object rotates right and if the user mouses to the left the object rotates left. Depending on how far they move the mouse the rotation should speed up or slow down.I spent a lot of time making an object in 3d studio max and importing the animation of rotation as JPEGs onto the timeline. I figured the most efficient way to go about this would be to make the mouse control the timeline instead of the object itself.
I am attempting to create 360 degree spin-around product viewer. So far I have a movie clip with 24 frames, each one with a different 15 degree angle shot of the product. Upon playback of the movie, the product appears 3D, spinning 360 degrees.
That was the easy part. Now what I need is to be able to click and drag the product to change which view you are seeing (or which frame in the mc you are on) thus producing a spinning effect. How can you code, in AS3.0, that when the mouse is clicked and drug, go to a certain frame based on the current X position of the mouse?
where i can find a script to attach to a movie/background image so that i can make the movie clip pan left or right based on the mouse position (with easing too!)? Example http:[url].... make sure you enter the site thats where you will see what i mean. I've been wanting to create a page like this for some time using png files and transperency and multiple layers.
I have created a globe that rotates with no problem, but what I am trying to do is to control the direction of the rotation based on the mouse position. For example, if the mouse is to the right of the globe, it rotates towards the right and if the mouse in on the left, the globe rotates left. When the mouse is over the globe, it should stop.
I am trying to make an animation where the user can mouse over a small MC at the top of the stage, which controls the movement of another larger MC at the bottom of the stage.I am thinking that 'points' (which I know nothing about) might be the way to go. The other thing is that it needs to be fluid motion. Am I at least on the right track with points and mouse_move or is there a better approach for this?
I have been racking my brain trying to figure this out for some time. I have some animated links that activate based on mouse position. The problem is when you whip the mouse over them quickly and it leaves the dimensions of the project, flash thinks the mouse is still there and the links continue their animation. IT IS EXTREMELY FRUSTRATING!! I have a feeling its a simple fix but i cant figure it out. here is the site - [URL] the actionscript is below...probably the most round about way ever devised.
I need to move a movieclip based on mouse x position. Like this site [URL] - Which I built using a flashloaded app, but I need more control in this project so I'd like to code it without the app. Basically, I have an image of a boy (left) and a girl (right) and I want to move the boy slightly toward the girl when the mouse goes right and slightly away when the mouse goes left. But only about 25-50 pixels in each direction.
I've cobbled some code together from google searching and rough ideas, and it works in a way, but the boy jumps about 400 pixels to the left on the initial mouse move and then floats a bit too far right and left from there. Here's what I've got on the boyMC:
I am having difficulty with getting the playhead to move inside a movieclip based on the horizontal or vertical position of the mouse on the screen. I can get the horizontal motion to move the playhead, but I can't get the vertical movement to do the same. I have attached the document class .as file for it.
Is it possible to draw motion guide/path for a mouse position based movement?
For example if I have path the is like letter H. I would need to write many clauses/conditions for the borders of the movement. It would be a LOT easier if there would be some solution that makes the object always to stay on the defined path when moving..
The main FLA has buttons linked to external swf files that are nested in a layer inside an html file. When rollover occurs, it opens up corresponding swf file. Problem is that when a user moves mouse too quickly over the stage, the rollout gets stuck in the last button the mouse posssibly passed by.
I got this expendable Bigbox I made for my client. All works well. The only problem I have is that, where there is a quick mouse (not event THAT quick) rollout, the action (closes the expended portion) doesn't work.It get's stuck and doesn't gotoAndStop(1).
Basically the x position of the mouse should control the play position of a movie. Do I need something like an event handler (I'm not sure exactly what these do, but I've seen similar scripts that seem to use them).
I have an Input Text area that users can edit and then submit. I need to be able to show, on screen, the cursor's current position as they type. I don't need to know where the mouse is but all work-arounds I've found so far can only tell me the mouse position. The font for the text is 'courier' or 'courier new' and the Input Text area is scrollable.
I have a map application that when I use the mouse wheel the map will scale up or scale down. The next thing I want to do is to focus on the mouse pointer while zooming on the part of the map.
I have this code...
function focusMousePosition(){ onMouseMove = function (){ Stage.width = _root._xmouse; Stage.height = _root._ymouse; updateAfterEvent(); }} var mouseWheelListener = new Object();var wheelNum:Number; mouseWheelListener.onMouseWheel = function(wheelNum){ focusMousePosition(); if (wheelNum > 0){ map._xscale *= 0.9; map._yscale *= 0.9; }else{ map._xscale *= 1.1; map._yscale *= 1.1; }}Mouse.addListener(mouseWheelListener);
The problem with this code is that it scales from the registration point (0,0). Due to the other transformations I'm doing to this image at various times, it isn't possible to move the registration point. The image is larger than the stage and the user is able to drag it around. I want the mouse wheel to zoom in on the place the mouse is hovering over (or at a minimum...the center of the "view" they have...aka the stage)I tried doing this:
Code: internalPoint = new Point(Map.mouseX, Map.mouseY); externalPoint = new Point(stage.mouseX, stage.mouseY); var matrix:Matrix = Map.transform.matrix;
[code]....
Which, incidentally, I'm using that whole portion of code to zoom into the state they will be in when they use the mouse wheel.
I am working on a site, that has 5 main pages: the home, and four sub-pages. Essentially, I have an element that slides up over the screen anytime you click "from" the home page to one of the remaining pages. Consequently, when returning to the home page, the element slides away / off the screen.
I am thinking the best way to handle this is with a conditional statement, but not really sure at all how that code would look especially in relation to position. My thinking for the code would be as follows:
I would like to input a certain (x,y) coordinate and have a function return which movie clip is based at that location. Is such a method possible, to refer to a movie clip based on its position rather than instance name?
how to get the X and Y coordinates of a character in a string based on index? I find it odd that I can get the exact letter and index by clicking a character in a text field, but I haven't found anything in code that can get those coordinates without a user click. Seems like they would have to know the x,y of the individual indexs to be able to tell you what letter you're clicking based on your own mouse coordinates.
In my code I am creating MCs and having them drop down the screen at varying speeds, but am having a hard time thinking of an easy way so that if one MC 'overtakes' another slower-moving one it will be displayed above it.I really don't want to have to run a hit test every frame for every MC through the array of MCs..
I have a thumbs_mc with thumbnail images. Within thumbs_mc, I have a transparent overlay_mc that functions as a button. Mouse over the overlay_mc and the alpha chages so there is a tint over that particular thumbnailWhen overlay_mc is clicked, the main timeline goes to a particular frame label.What I need to do is have the position of the playhead on the main timeline also determine the alpha of the overlay_mc so the viewer knows which thumbnail is playing.
Any smart people out there who can tell me why this function Im working on to automatically sort the depths of objects placed on the 3D plane is only working intermittently? It seems to work every second or third iteration?[code]Is getChildAt(i) reliable? IE does it return the same order each time it runs or is it based on depth? looking at the manual suggests that it's probably the latter so I guess I'll need to make my own array ordered by the time the sprites were added to the parent and work from there. Is there a better way?
