ActionScript 3.0 :: HitTestPoint & Mouse_move?
May 19, 2009
I have been using hitTestPoint so far with mouse_move listener, which means if the mouse was stationary over target area when that listener was added the desired action wont happen until mouse moves.
Basically I have this window in the middle of the stage where loader loads pictures and when picture loads if the mouse moves over that window some other stuff appears.The listener is added after each picture is added and if the mouse was stationary above the loader when that happened it doesnt trigger hitTestPoint (until mouse moves).
I have seen somewhere this same effect, but it worked even if the mouse was stationary above the image when image appeared.

Which one is more efficient? Or is there even a noticeable difference? I did tests of a circle moving closer to a square and stopping when hitTestPoint returns true. The square was at 0 and the circle was at 500. My first test I did using hitTestPoint the entire time, my second test I did by checking the distance (Pythagorean Theorem way) and if it's below 50 then check with hitTestPoint.
I compared the FPS of each test but they were the same at 30 FPS with 200 circles and at 11-12 FPS with 500 circles. I thought the first test would be slower because I was testing every pixel the entire time while the second test I was only calculating the distance for the most part before testing every pixel.

I've got a png sequence of a 3d object rotating on my timeline. My as3 find the mouse.x and uses math to choose which frame in the sequence to move to. I need to be add easing to the movement.
AS3 in use:
stage.addEventListener(MouseEvent.MOUSE_MOVE,findF rame);
function findFrame(event:Event):void{
var frame:int = Math.floor((stage.mouseX/stage.stageWidth) * 31);
gotoAndStop(frame);
}

I need to dispatch an event object when user stops moving mouse cursor. In poor words, i need the exatly opposite of a Mouse_Move event. Is there any solution or I need to create a event with EventDispatcher class?

i'm attempting to implement a mouse event where Mouse_Move can only occur if Mouse_Down. i could introduce a boolean that would toggle during Mouse_Down and Mouse_Up that could work, but is there a better way, perhaps a more official way, of doing this?

I have a disc I am rotating with the mouse with event.MOUSE_MOVE, like a jog wheel on some audio equipment. Everything almost works as expected, but the problem I am experiencing is that the disc always jumps to the point where the user clicks on the disc. I need the point on the disc that the user clicks on to remain under the mouse while the user spins the disc but I can't seem to come up with the correct math to make it happen. Here's the code i am using:
var xd = (_knob.x - _stageRef.stage.mouseX);
var yd = (_knob.y - _stageRef.stage.mouseY);
var radAngle = Math.atan2(yd, xd);
_knob.rotation = int(radAngle * 360/(Math.PI * 2) - 90);
_knob is a vector circle wrapped in a movieclip, with the circle centered on the movieclip's reg point. _stageRef represents the main stage.

why it scrolls down fine but when it scrolls up the first line of text falls to the middle of the pageContainer?the height of the pageContainer is 440 pixels.I cant get it to stop at the top of the pageContainer.It just keeps going up (into blank space)and the text keeps moving. Heres the code:
pageContainer.addEventListener(MouseEvent.MOUSE_MO VE, scrollPage);
function scrollPage(event:MouseEvent):void
{
TweenLite.to(pageContainer, 0.5, { y:-(mouseY/440)*pageContainer.height+stage.stageHeight/2});
}

I'm programatically dragging the play head back and forth along a timeline based on a mouse event listener. The faster the mouse drags the faster the playhead rips through the frames (it's linearly proportional). I'm also firing a starter=getTimer(); event at the inital mouse_move Event trigger (and only on the initial event) and then firing a ender=getTimer() at the end of the code that calculates the new playhead position, but only if the calculation has resulted in the playhead being told to move at least one frame (the mouse can move a few pixels before playhead will move one frame). In essence it's giving me a frame per second rate.
If I look a the delta of the two timers I rarely get anything but 0. Occasionally I'll get a 1 but not very often. There are a good few dozen heavy lines of code that need to be worked out between the initial mouse_move and the decision to move the play head, and this has to be done for a number of mouse position changes before the playhead will move at all and the second getTimer call is triggered. Does the mouseEvent trigger every ms or does it trigger at the frame rate (enterframe rate) of the doc. If so the smallest delta I should see is 31ms.
This runs as an app in the standalone swf player (10.1) and never in a browser.
Are my results indicative of this? Can the compiler really run this fast? How does one do very small timing tests that appear to be beyond the millisecond clock granularity?

My code seems to be hearing a MOUSE_MOVE event when you click outside of the Flash stage (anywhere else on the page).
I have one listener for MOUSE_LEAVE (stage), which hides some overlay controls after a 500ms interval, and another (MOUSE_MOVE) to show them again when you move back over the stage. Yet the controls show again when I click anywhere outside of the stage.
I suppose I could add a Boolean for whether the mouse is over or outside of the stage (since I'm tracking that anyway), and *not* show the controls if its outside, but is there something else I'm overlooking?

I have a module, which is a simple swf file to load.
Inside there, in a modules document class I have a code like:
ActionScript Code:
buttonMode = true;
useHandCursor = true;
[Code]....
When I load the module, I can see the drawn background with proper sizes. However, the cursor is not hand (useHandCursor) and mouse events are not dispatched. They are only dispatched on some children of the document class, not on itself, on its own background. ANd the hand cursor is only over the children, not over the document class' background itself again.
The document class of the module extends Sprite.

I'm getting a flickering issue with my tool tip hovers. I've tried writing the code in 2 different ways and I'm still getting the same thingEach way seems to work fine if there's only one object, but when there are more than one and you start moving the mouse between the 2 this really annoying flickering keeps occurring? My file needs to have several objects which all overlap. I've tried altering the hit areas so that they don't actually touch - but no effect.
I've also tried swapping ROLL_OVER for MOUSE_OVER and MOUSE_MOVE but all with no results.

I'm listening for MOUSE_MOVE events.They are sent and received just fine unless the middle mouse button is held down. I don't get any more MOUSE_MOVE events until the middle button is released.Is this an issue with Flash, or something to do with my specific ouse/computer configuration (bluetooth Mighty Mouse on Lion)?Are there any known workarounds?Here is a sample project to demonstrate the problem.Left click and drag traces mouse move events, but middle click only shows middle mouse down and middle mouse up.
import flash.events.MouseEvent;
this.stage.addEventListener(MouseEvent.MIDDLE_MOUSE_DOWN, onMiddleMouseDown);
this.stage.addEventListener(MouseEvent.MOUSE_DOWN, onMouseDown);

Trying to use the MouseEvent.Mouse_Move event. Simply, there's one 300 x 20 line which the event is assigned and another line (100x20) is top of the first line. But if mouse moves over the second line, the event is not working... The same event could be assigned on the second line but it seems a bit waste and I'm sure there must be a way to trigger the event through the other object.

I would like to know how fast, flash player processes the Mouse movement? Does it process mouse movement at the same speed as the fps(frames/second) of the flash player .
For example for a function added as a listener to Mouse movement say, stage.addEventListener(MouseEvent.MOUSE_MOVE, mouseMoveListener); Does flash invoke this function 'mouseMoveListener' every time the mouse is moved? Is it done at the same speed at which the Operating system handles mouse move ? Or is it lesser? If so, then by what amount?

im trying to create a menu that drops down when you roll over it. however I cant get hittestPoint to work.I have a movieClip on my stage with a class attached. Inside this movieClip is another movieClip with an instance name of "hitBox"
ActionScript Code:
package {
import flash.display.*;
import flash.events.*;[code].....
Is it possibly to do with the mouseX and mouseY being local?

Anyone know why "hitTestPoint(character.x, character,y, true)" would be hit testing off the origin point in the center of the character, and not the whole shape??This is my code from my document class. There's a custom splat class in there, but don't worry about that. This code is inside 2(1 nested) for loops.[code]

I have the beginning of a game that looks a bit like Asteroids. The first version of the game worked, but was very code-heavy (every object was individually coded) so I decided to move the bulk of the code to document classes.
I wanted to have certain objects interact with eachother (bullets with asteroids, asteroids with ship, etc.) but they can't find eachother. Also, as you may notice in like a second from now, the whole code is handled by a single document. I guess I should do something about that as well?
Code:
package
{
import flash.display.MovieClip;
import flash.text.TextField;

is the way to test for the mouse being over a DisplayObject. This works if my movie is displayed at 100% scale. But if maximise my browser window so the Flash movie changes scale, it all goes to pieces.

Recently I was trying to use hitTestPoint with a nested movieclip against another non-nested one. Then if the nested movieclip was found to collide with the the registration point of the other movieclip (shapeFlag was set to true of course), the nested movieclip would move down by 1 pixel until it wasn't colliding.[code]What happens is that the while statement doesn't kick in until the registration point of obj3 is over obj2, but it doesn't break until obj3 is not over the bounding box of obj. Alternatively, if I change obj1.obj2.y to obj3.y it does stop at the correct spot.Actually I guess the problem isn't obj2 being nested in obj1, the problem still occurs when it's taken out of obj1.
