ActionScript 3.0 :: HitTest For Mouse Position Over A Bitmap Inside A MovieClip?
Dec 1, 2009
This seems like it should be simple, but... I've been trying to figure out how to do the following, and I can't seem to make it work. It all works except for the hit test part. I have a working drag and drop application. I need something different to happen when the user drops an object while the mouse x,y is, or is not over a certain (very irregularly shaped) bitmap inside a movieClip. how to do this? I have found some complicated ways to hit test between 2 bitmaps, but not 1 bitmap and mouse x,y.

how can i test the position of the mouse inside the area of a specific movieclip WITHOUT using rollover and rollout events?
the movieclip is the irregular shape (star)
i need to do some action according to the position of mouse (inside/outside of the movieclip area) but i can not use rollover event because i have a button placed over the movieclip.

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.

Ive got a code to move a MC on the main stage together with the mouse, in the the X axis,. difficult to explain. But now the client wants that this MC movement works only when the Y position of the mouse is over the 300 px. I thought I need a hit test or something elese. Please help. Here is the whole code.

i just would like to know how to create an "hitTest" script inside a movieclip that is actually part of that hitTest code?I mean... I have mc A, and mc B. and the current hitTest code im using (that is on the timeline) makes mc A, destroy mc B when collide with it... but there are many mc B on the stage (with the same instance name) so, when mc A collide with one mc B, it destroys ALL mc's B... but i want it to destroy only the mc B that he collides, not all the others... maybe an hitTest script inside a movieclip B would work (somethig like "if MC A hitTest ME = i die" (not all the others)).

I'm cutting my teeth in actionscript 3 on a game that has a character running through a world. So, I have set up my Hit Testing by using the bitmap data hit test method, since I figured my world is going to be destructible - it'd be nice to update the level and then redraw it and have the character interact with the new change. (That works beautifully) I am however; a bit confused as to how I have my hit Testing set up. I've been messing around with it, and it works for now - but I'm not sure why.. currently, I have a character set up by using a class I built and using a series of animations I created. So, this character has a walking and falling animation, etc. This is a movie clip.
Then there's a bitmap 'emptyBitmap' with bitmap data created - however; I never really added this as a child to the character. This is sized to the dimensions of my character. My level is created as a movielip, then it's drawn to a bitmap - when the level movieclip is changed, the bitmap redraws, and that's how this updates.

URL...The game has a helicopter centered on the screen (the heli movieclip is in Scene 1, frame 1, Layer 2). Then I have a "World" movie clip on Layer 1. Inside the world movie clip are the enemies, weapons, and boundries of the map.The world movie clip is moved when the controls are used to make it look like the helicopter is moving (although it is actually stationary). When the space bar is pressed, the "bomb" movieclip inside of the "world" movie clip is duplicated, and the duplicate is placed at the correct coordinates in the "world" movieclip so that it seems like it is coming out of the helicopter. This is all working as intended.The problem comes when trying to hitTest the bombs with the boundries/enemies inside of the "world" movieclip. The "boundry" movieclip is also inside the "world" movieclip, and is part of the Boundry class. The hitTest is inside my "bomb" class. Heres the code:[code]But the hitTest just doens't work. I've tried every combination of legal hitTest statements between the two movieclips, and it wont work. As you can tell from the SWF...the bombs explode seemingly randomly. SO somewhere...somehow...the bomb is colliding with the boundry.

I have a MovieClip. It represents animation of jumping monster. For clearness, let's pretend there are only 2 frames: the first one occupies top left rectangle (x = 0, y = 0, w = 70, h = 70) and the second one occupies (x = 100, y = 0, w = 70, h = 70). So monster jumps from left to the right. And position of MovieClip itself is constantly = (0, 0).
I'd like to fire some event when monster is clicked by mouse.
For some reason, I have stage mouse listener, not monster mouse listener. I wrote this code:
stage.addEventListener(MouseEvent.CLICK, onClick);
private final function onClick(e:MouseEvent):void {
const clickPos:Point = new Point(e.stageX, e.stageY);
// having monster:MovieClip, how do I check hitting it?

I have a movie clip called "myMC". I set its x value as such:
[AS]
var myMC:MovieClip = new MovieClip();
addChild(myMC);
myMC.x = 100;
[Code]....
I know I could proboly acheive this with a math equation but is there a function that can get the exact global position of "myShape"? So that I can position another movieclip or sprite around that movieclip?

Okay I have a script in which I have added an image to the stage. It is absolute centered. I then have another with is on top but much bigger. I would like the big image to move opposite of my mouse position on the smaller image. ie: cursor is on bottom left corner the bottom left corner of the larger image is in the same spot. And the same thing for any other area.
I have tried many different ways but to no avail. I have done research but no one has been able to give me a solid answer. Anyone know of a way to accomplish this. Keep in mind this it needs to work regardless of the image size.

I have searched several threads, and no answer has been found to apply a bitmap smoothing to an image already inserted inside a movie clip on stage (not dynamically loaded). Any suggestions on what to do to apply smoothing to an image inside a clip? Trying to come up with an answer as I am getting a funny fuzz around a logo that I'd like to see disappear. It appears clean and crisp within the png file, but not in the compiled swf.

I have a mc on stage. I want to add a new mc inside it and position it at the bottom of the mc.
The code works fine when the container mc is 100% scaled, but when I scale it, the mc inside positions wrongly.
Heres my code:

I am trying to activate a rollOver-function when the mouse rolls over a movieclip inside of a movieclip.On the main window (root), first you rollOver a button where a window shows up with more options (movieclips).From stage, my first movieclip is called "catapultas_read_more" which leads to amother movieclip called "pic1_mc". The label that is going to play when mouse over on pic1_mc is "rollOn".I tried this.gotoAndPlay("rollOn); directly inserted to the movieclip, but the movieclip inside pic1_mc never starts

I am using Action Script 3.0 to animate an instance (MovieClip class) to follow the mouse positron the thing is, the left corner of the instance follows the mouse courser. Now there is a cross on the to left corner and my guess would be that the mouse follows that cross, but i can not change the position of the cross within the instance/ original object. Does anyone know how to make the center of that instance follow the mouse cursor?

Essentially what I'm trying to do is nearly the same as this: http:[url].......However I'd like to ease/tween the movieclip position and rotation to the mouse position.The main issue I see is trying to get the current movieclip rotation and the target rotation,then tween it cockwise or counterclockwise from current to target.The way a movieclips rotation uses positive and negative numbers throws it off.If you just want to lock the mc rotation to the mouse rotation its fine, but once you try to tween it you run into difficulties. So the end effect would be like if you were to draw imaginary clockwise circles around the object, it should just keep rotating clockwise towards the mouse. Then if you started going counter clockwise it should just keep easing counter clockwise to the mouse.

I am looking for direction to this old UFC effect - [URL] that appears on the main page. It is movieclips rotating on different axis based on the mouse position. So far I have found this script:
stage.addEventListener(MouseEvent.MOUSE_MOVE,EnterFrame);
function EnterFrame(e:Event)
{
mc.rotation = (180*Math.atan2(mouseY-mc.y,mouseX-mc.x))/Math.PI + 90;
}
But this only rotates on x and y. What's a way to approach this effect?

i have a pie chart with clickable sectors. when you click a sector it jumps to the next frame on a movieclip and changes colour. I want to use Local Shared Object to save the frame position so when i come back to the swf later on the sectors of the pie chart are saved.

this concerns flash cs5 and the timeline.Everybody knows the effect you get when you use appendText() to add text to a multiline dynamic textfield, right ? Well, I have a movieClip as a container, and I would like dynamic textfields to populate this movieclip in the same manner as textStrings would populate the dynamic Textfield.
How would this work?I have buttons that trigger addChild() function so as to populate the movieclip with textfields, but how do I make sure that the textfields make up an arbitrary list as a menu user chooses which buttons to click?
Let's say this is the visible text when the swf runs.(I cut away some of the code to make this more to the point):
var buttonTrace:TextField=new TextField;
addChild(TextClip.buttonTrace); buttonTrace.x=0;
buttonTrace.y=0;
buttonTrace.text="Breadcrumbs";
Now for each time I click a button in the menu I've made, a new textfield appears with the name of the button. This is how I want it. BUT......... How do I control the display properties and positioning of dynamic textfields within a movieclip ? How do I control persistent visibility, and how do I make these textfields appear one after the other in the order they were clicked.

I have some little listener.
stage.addEventListener(Event.RESIZE,rozmiar1);
function rozmiar1(e:Event):void

ofertaBTN.oCenter.width=(14.59*stage.stageWidth)/100;
ofertaBTN.oRight.x = ofertaBTN.x+ofertaBTN.oLeft.width +ofertaBTN.Ocenter.width;
}
But only ofertaBTN.oCenter.width is changing. oRight is not responding and I get error #1010.

I have a basic script that moves a movieclip to the opposite Y position of the mouse pointer:
Code:
var cP = this.createEmptyMovieClip("centerPoint", 1);
cP._x = Stage.width / 2;
cP._y = Stage.height / 2;
var myBox = cP.attachMovie("boxMC", "myBox", 2, {_y:cP._y});
cP.onMouseMove = function() {
myBox._y = (cP._ymouse * -0.9);
};
Everything works great, but I'd really love to be able to ease the box to it's Y position, rather than moving it to it's final position immediately. I'm having a difficult time with it because the box is moved based on the mouse position, which obviously doesn't ease.

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 have two png files, a circle and a maze. Basically the maze is a square with some paths carved through it. I want to draw these images, move the circle to the mouse coordinates, and have a text say 'hit' when the circle intersects a wall of the maze and 'miss' when it doesn't. Now I want to do these using the bitmapdata.hittest method. The circle is a 32x32 image and the maze is a 256*256 image. I've gotten everything set up and everything draws on the screen correctly but I can't get the actual collision detection part of it to work, that is it always displays 'miss' rather than 'hit' even when the circle clearly intersects the maze.[code]

How would you force a mouse follow movieclip to snap to a x y position if it reaches x y boundaries or perhaps if a button is released the movie clip snaps to a x y position? Of course if the mouse returns to x y boundaries I'd like for the movie clip to follow again.
Right now this is the code I'm using to make the movieclip follow the mouse within x y boundaries:
Code:
onClipEvent (load) {
_x = 0;
_y = 0;

The other is a scrub that manipulates a MovieClip, but tracks a change in mouse position from click to release, instead of tracking the changes in position of a slider playhead. But here is the download for that one:(sorry not a link due to not having over 50 posts yet, you will need to copy and paste)I have found plenty of AS1+2 ways of doing this idea, yet just haven't found any solid AS3 versions.I am currently in a class to learn Actionscript and have tried to figure out this problem yet I am just not yet to that level.

I have recently followed a tutorial to make a movieclip in flash that makes buttons spin around a point depending on the mouse position. I have made my own version off this and would like to use it in a full flash website that i am making at the moment.
The only problem that i am having is with aligning this clip and as it is made up of script i cant physicly drag it to were i want it. I understand how to alighn this with x/y positioning but when i preview the flash in a web browser it is positioned correctly but then when i 'full screen' the browser this clip jumps about 4 inches down the page.
