ActionScript 3.0 :: Pushing Objects Away From The Mouse?
Feb 10, 2010
So I've been working on a little particle generator that produces intractable particles. When you click your mouse, they will move in a straight line away from where you clicked. Seems simple enough, but I can't quite get the formula right.
I want to pass two points and a magnitude scalar value into a function and have it move the particle along the line drawn through the two points, and only as far as the magnitude specifics.
For example:
Let's say the particle is at the point P(10,10) and the mouse clicks at the point Q(15,15). I pass both those points and the magnitude 10, into my function.
The function then calculates the angle the particle should travel (45 degrees or PI/4 radians) and sends the particle to the point O(20,20), again, as specified by a magnitude of 10.
This seems like a simple problem, it's used ALL the time, but I just can't seem to work it out.
Side note: By the way, I'm using ActionScript 3.0, but if possible I would prefer a universal explanation in case I decide to program this in another language, or I am without a programming language when I need to figure it out. T
I have a draggable button/rectangle that when goes ontop of other objects they are being pushed away depending on the less distance around the rectangle.
If someone knows a tutorial or something that could help me please say
I started with if (button1.hitTest(button2)) { ... } but I dont know what to do next

I've been reading a lot about the benefits of Object Pooling. Found some "tutorials" online, all above my skill level. Can anyone please show me an extremely simple example of an Object Pool. What my game does is creates Ball objects when the user holds down the mouse, stops when user lifts up mouse. I need to store these Ball objects in an array(or Vector), and hit test them with other objects, removing them from the stage when the hit another object. I'd like to create a pool of say 20 of so, created once, and recycle them.
I've seen couple of websites [URL]...in these websites the text & the objects move with the mouse moves. I just wanna know how to move the objects with mouse movement or you can say how to make an object follow the mouse (left-right-up-down)
P.S. In the 2nd website there's a 3d character also which I don't have in my project so there's nothing to worry about 3d in flash. I've just couple of images & text
I have played some more with Flash and come upon something that i would know more about.I tried to make:A scene. when I click the left mouse button on the stage an object(from the librery [graphic]) will be place exactly where the mouse is.I did not really know how to approach this, but tried anyways.
This is my code:
stage.addEventListener(MouseEvent.MOUSE_DOWN, addApple); Function addApple(event:MouseEvent):void{ //I dont know what to put here to place an object(apple) from the libery //onto the stage where the mouse is. };
I'm making a catching game and I only wanted the falling objects hit certain area on my catcher. My catcher is a girl with mouth open and I wanted the falling objects to hit only the mouth, not any other parts of her body like arms. So I made two objects, the full girl and just the mouth. How do I make the two objects (movieclips) move around with the mouse?I tried to embed one object into another but it didn't work....
This is actionscript I wrote so far: package { import flash.display.*;
Basically i want an object to avoid/dodge the mouse. But i want the mc to have a fixed x and y to move back to once the mouse is away. I also don't want it to jump, i want it smooth like a follow mouse effect.
Apparently it's relatively simple in AS3 using a stage mouseevent.MOUSE_OVER listener, but I need an answer in AS2, which doesn't have the mousevent listener. Is the only way to get a list of objects under the mouse cursor, to do a recursive list of every object in the file and do a hitTest to get true/false on each? There must be a simpler way, right? I've seen a bunch of comments on forums that say "use hitTest", but hitTest just returns true or false, and not with the name of an object you hit, so maybe there's a way to use it that I'm not considering?
i got 5 bubbles on my stage and each is moving from the bottom to the top. additional i want to be able to push the bubbles with the cursor.this is working, but only on 1 bubble ...
ActionScript Code: function image_move(e:Event):void { for(var i = 0; i < bubbles.length; i++) {
I have several shapes on the screen implemented as movieclips.I need to allow the user to drug the objects with the mouse as well as to resize them (i.e. to change objects' _xscale and _yscale)To do every one of these tasks (drug, blow up and blow down) separately is a trivial task.
I want to make some mouse effective objects like if some one touches the mouse pointer to that object then it will go away but after some time will come again at its defined position.In my case I am using a frog which is randomly moving in a pond but when we takes mouse pointer near by it it went far. and after some sec. will come again and takes the position.[URL]I am using a script which is not enough it works to take object far but how to bring that object back in the defined place.

I am working on a Flash photo project where a small image is shown with a square that follows the mouse. Below will be a larger image that moves with the mouse simulating a larger view of what is under the mouse pointer. Though I am making progress with this, I am having problems getting the two pictures to sync up.I am currently using Flash Pro CS5, but have been saving as a CS4 project in case I have to work in it later. I don't know if that makes a different in actionscript 3.0, but I thought I'd include it anyway.I tried to attach my file, but the 300Kb limit stopped me. Here is the code I am using so far though.
I'm a bit slow when it comes to grasping this whole concept.
I am after a script that allows me to use my mouse and repel objects within the canvas in Flash. For example, if I move my mouse close to a shape, say a circle, the shape would immediately dodge the mouse.
How can I make a mouse event ignore, or skip over another object? Say I have a small Sprite on a Large sprite, I want it to act as if the small sprite isn't there, and pass the mouse events directly through to the larger sprite behind it. I've been searching for this for a while and have tried various things but no avail.
say I've got a button I push to add a currently selected term inside a text field/input field to an array, but I don't want to accidentally add the same option twice, or see the same option over and over, what do I have to do to the array?here's the original for an array called aNameslist and a variable callednamesDaddmcD.onPress = function(){ aNameslist.push(namesD); }What's necessary to switch an output like
I have about 4 or five objects moving around the screen. when I rollover one of the objects, I need all the objects to stop moving... when i move the mouse away from the abject, all objects on the screen need to start moving again.
I'm trying to think of the best way to add event listeners(mouse events) to an invisible object which is quite large. A straight forward way I can think of is probably setting the object's alphy property to 0. However since that object is very large, it will probably have a huge impact in performance. Setting invisible to flash however, will stop it listening to events.
e.g. I have a massive area 4000x4000, but I only want the 2000x2000 area to listen to events.
Other methods I can think of is to have the smaller area in the layer below the big area, covering it from view, though I'm not sure if the lower layer can pick up events? another way is maybe just have the big area listen to events, but in the handler I'll write some code to check if its within the boundary of the smaller area.
I have proper code to make objects rotate on an axis adjacent to the mouse. I also have proper code on how to make objects elastically bounce towards a specific x,y coordinate.
So far the code I have is for the object to follow the mouse when clicked. when the mouse is up, the objects (on a rotational axis) wind back to original position.
What I would like to do, is combine the formulas for rotation with the elastic formulas to bounce these objects back into place with rotational movement.
Is it possible to push an object into a specific index in an array. Because I have a set array from 1-10 and each index has a unique purpose so I was wondering if it would be possible to do something like:
array[1].push(object);
If not whats the best way to do this? At the moment I have a seperate array and I just do array[1] = arrayOfObjects.length -1;
Im currently trying to modify Lee Brimelows videoplayer, however im not quite sure how to achieve what im looking for and need suggestions. I'm looking to have 3 different movieclips. Lets say
[Code]....
So guess I need to make a listener for each button, and within each of the listeners, define vars for the movieclips. Then make the EVENT listening for clicks, and when clicked, push the new movie into ns.play?
ok this is going to be tricky to explain. The scenario is i have an array like so Code: var Final:Array = new Array(); and i have a class with a bunch of variables grouped together (no function in this one) the original reason was for this to serve as a way making seperate instances (something like a structure from C++ i suppose) when needed but once i explain further it might just be making it more complicated. now what im doing is to use array.push to add new objects inside the above array. but the problem is every time i push i mostly likely will need to "create" a new instance of the object am i correct.but i cant do that sice the function that does will have a static name for the instance of the object i push into the array.
i hope that made sense, now what i need as a solution is some way to dynamically add unique instances of the object into the array without having to have unique names everytime. i can only see two logical method of doing this, one is to figure a way of dynamical naming the instances, or to have some sort of syntax like array.push(new Object(Copy stuff from a temporary Object)); But one more would be to avoid using objects all together but even that ive tried to figure out
correct syntax for pushing variables to arrays within arrays? I have searched many threads but found nothing that exactly answers my query. I have a class (Brigade) which amongst other variables contains an array (BrigadeUnits) This is the third element.. My Brigades are stored in an array called AllBrigades. I now need to fill the BrigadeUnits array with objects of my Units class. The hierarchy I want to create is as follows:
I want the diameter of the 'balls' orbit to change dependant on the position of the mouse but keep the point of rotation exactly the middle of the stage at all times.I.e. if the mouse is hovering over the exact center (both X+Y) of the stage then the 'ball' should have a tiny diameter of rotation (but contstantly follows the orbit in clockwise direction) whilst if you move the mouse towards the edge of the stage then the diameter of the orbit of the ball will increase.Here is the AS which controls a blank movieclip;
var sp:Sprite = new Sprite(); orb1.addChild(sp) var g: Graphics =sp.graphics
