ActionScript 3.0 :: Which DisplayObject Is Visible At Position X,y
Mar 3, 2009
I want to know which DisplayObject that is visible atposition x,y. Unfortunately, hitTestPoint returns true even ifanother DisplayObject lies above and blocks all visibility. Forexample:
When I add a DisplayObject to a DisplayObjectContainer (e.g. a Sprite to a Sprite) in a function, it seems that the DisplayObject is actually added not immediately, but after finishing the function.[code]...
When I add a DisplayObject to a DisplayObjectContainer (e.g. a Sprite to a Sprite) in a function, it seems that the DisplayObject is actually added not immediately, but after finishing the function.
So we have a simple green button, and when it is clicked, there's a red Sprite constructed and added to the stage. But actually the red Sprite isn't visible until the onClick() function has been fully executed.
Why is that and what can I do for the red Sprite to be visible immediately?
Is there some (for the developer invisible) global paint() or update() function, that is not executed until some stack is fully executed or something?
The following is entirely a math question. As we know, PerspectiveProjection delivers perspective transformations in 3D represented by the interdependent values of fieldOfView and focalLength according to the following formula:
Q: How to get the visible on-screen size of the DisplayObject (Cube on the above-linked image) to which PerspectiveProjection has been applied? A more thorough description and illustrative code on the issue in ActionScript 3 lacks functionality for visible bounds of DisplayObject.
I've been banging my head trying to figure out how to get this to work with no success... I have a class that extends MovieClip which loads a large image into it. This image has a mask applied to it to only display a specific section of the image. I need to be able to scale this MovieClip based on it's visible width & height while maintaining it's proportions.
I'm currently using Collin Moocks' approach (see it here:[URL]) to get the visible width and height of the movieclip, but I can't figure out how to get it to scale correctly based on those dimensions... Preferably I'd like to be able to set it's visible scaleX & scaleY properties similar to how you currently set the scaleX & scaleY, (i.e. movieclip.visibleScaleX = 1.5).
Has anyone got any alternatives to what Colin Moock has coded to GET VISIBLE WIDTH/HEIGHT OF A DISPLAY OBJECT in ActionScript 3? That esp. in perspective of DisplayObjects that have 3D transforms applied and visible dimensions of which you need to consider for a calculation.
I animate a DisplayObject with a Motion XML (exported from Flash). The first time I apply a motion to it, everything works fine. The second time I apply a motion, the position / scale is reset to what it was before I first applied a motion. How can I keep the transform of the DisplayObject after a motion is played when I want to play a new motion ? I want the DisplayObject to start from where it was at the end of the first motion.Here's the code I use:
private function animate(motionXML:XML, target:DisplayObject):void if(!animator)animator = new Animator(motionXML, target); // Add event listerners
I would like to be able to quickly check if a given DisplayObject is a descendant (not in the inheritance sense - ie. child, grandchild, great-grandchild, great-great-grandchild, etc.) of another DisplayObject. There doesn't seem to be a native way to do this and I can only think of two ways to achieve it: Create the mother of all nested loops. Seems a bit, I dunno, wrong? Dispatch a bubbling event at the 'child' and check if the potential 'parent' receives it.
My question is: Set parentSprite.visible = false will make all children in parentSprite all invisible, right? And is there any way to just make parentSprite itself invisible without effecting it's children?
I want to click on an object and make it appear and disappear. As the object is rectangular, I figured putting a white button the same size on a white background on a layer underneath the object would do this, but I can't seem to make it happen.I'm a complete novice, frustrated as I've been trying to achieve this all day and I'm sure it should be pretty simple, but could you give me the idiots guide. I know how to name an instance, make an object, script in actions on a separate layer. I would like to draw the button myself and give it an instance rather than drag it off the button component (as I can't work out how to make the component button white, change its size etc.!)
When the checkbox (cb1) is clicked the "my_Dyn_Txt1" is visible. The problem I'm having is - when I move forwad and back in my frames the checkboxes which were clicked are not visible due to
Code: my_Dyn_Txt1._visible = false
How can I make ("my_Dyn_Txt1"), a clicked checkbox STAY VISIBLE even after I move forwad and back in my FLA frames?
Okay, this should be relatively easy but I'm running into errors. My main character is visible in the beginning of the game (where the main menu is) and because I coded it so that all of the enemies don't spawn unless the main character is visible, the enemies spawn too. As a result, if you stay at the main menu for long enough, the score continues to go up, the health goes down when enemies attack, etc.
when the video reaches 1 minute, a button appears. is there a way to hide the button again if the user uses the seek bar to go back to the 30 second (or any time before 1 minute) point?
I added a Menu_mc on my stage. Initially, this should be at the center of the stage and when I click on it, it will tween on the upper left corner of the browser. However, when I resize the browser, the Menu_mc goes back to the center of the screen.
I have tried separating a different actionscript file where it is specifically for initialization of the object and another one for resizing. And then when I call it on my main AS file it goes like this:
Code: // Add the symbols to stage var Menu_mc = new Menu_MC(); addChild(Menu_mc);
I am using a ScrollPane in my application(viz., instance name is: myScrollPane). When I view the contents of the ScrollPane, it shows them perfectly. My issue is: When I try to view data present inside the ScrollPane, if I move the Vertical-ScrollBar of the ScrollPane to middle(or somewhere from top to down) and then click on Submit button(viz., instance name is: submit_btn), then its Vertical ScrollPosition must be reset from middle(or any position where we leave it before) to top(or initial position). Hence, I need to move the Vertical ScrollPosition of ScrollPane to top (or) initial position. Everytime, I need to refresh the VerticalScrollBar Position when I click on the submit button. How to do it?
how to make an actionscript to move punto_mc from current position to random position after release, and then from this new position to mevo to another randon position after release?
I have simple image gallery, where images are placed one next to another and the mask is revealing only one of them. Now I want to tween position of the images, but when I do that the mask is "traveling" alongside with the images..
So I'm trying my hands on some full browser flash and after reading a couple of tuts I wrote this
Code: #include "mc_tween2.as" Stage.scaleMode = "noScale"; stageListener = new Object();[code]...
The trace's are because it didn't work like I thought it would.Etc the middle movieclip didn't center itself but rather positioned itself seemingly how it pleased so I traced its x position and the var stageXcenter position and like suspected it shows different values.
I have a ScrollPane and I want to get and set the scroll bars position (pixel position). For example, if the user changes the scroll bars position and then refreshes the page, we need to take the user at the same point where he was before refresh. For this I need to get the respective scroll bars positions before refresh and then set it to the saved position after load. I have got the positions by hPostion and vPosition but now when I try to save the values back to the same properties after refresh it doent work.
var manTimer:Timer = new Timer(1000,14); manTimer.addEventListener(TimerEvent.TIMER, moveMan); function moveMan(e:TimerEvent):void {[code]....
I just need to make the tween's position relative to it's current position, as opposed to starting at the stage's 0 position then moving the the stage's -40 position. It needs to start at its current position the move -40 from that position.
I'm hoping someone can solve this headache. Basically, I want a movieclip to move to the position of each of my buttons from any position along my x axis. Therefore, the movieclip needs to 'flip' to face the way it is traveling.At the moment I have the movieclip moving to the mouse x axis when I ROLLOVER the button and stop following the mouse when I ROLLOUT but the code won't flip the movieclip so I must have something wrong...
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've run into a new problem, this time with positioning. I've narrowed down the line that's causing it--"block.y = block.y + block.height;" in SetOfBlocks.shiftDown. When I take it out, no problem. But with it in, instead of just dropping each block down by a block height, the affected blocks sometimes move up, and also often move about randomly within the X axis--although their new positions always keep them lined up with the 'grid', which is to say, within multiples of the block height and widths.
I have a sprite that I zoom out using the sprite.z property. Once the z property has been modified the sprite x and Y values do not match the stage x and y real value. So far so good and what I was expecting!
What I want to accomplish is that when the user clicks the stage the sprite tweens to where the mouse was clicked but I don't know what x and y position to send to the sprite. ( since stage 200,200 is something like 400,400 for the sprite depending on z value)
I tried Utils3D.projectVector using Matrix3D of the perspectiveProjection of the stage without success. (i.e. I get Vector3D(Infinity, Infinity, NaN))
I could fallback to scalex/scaley but sprites.z gives me the correct scale, perspective projection, paralax scrolling since I have sprites on different z level all for free. I would have to recode all that.
