I am trying to implement a quadtree of rectangles (instead of points) to be used for collision detection. For some reason, overlap/intersection/collision is not always detected. I suspect this has something to do with the way an inserted collider looks for nearby colliders (see the "COLLISION A" and "COLLISION B" sections of Quadtree.as). Can anyone identify why this happens?
Below is my code for the quadtree, and several other classes that, when compiled together, will show you what I mean when I say that the "quadtree" s "inaccurate". You only really need to look at Quadtree.as, but compiling it together with the other classes.
Code: for (var i = 0; i < clickArray.length; i++) { trace(clickArray[i].name); if (clickArray[i].hitTestPoint(mouseX,mouseY,true)) {[code].....
The code basically see if your touching of the MC in the clickArray and changes another MC's frame accordingly.This bit works fine. However, if I add an else:
Code: for (var i = 0; i < clickArray.length; i++) { trace(clickArray[i].name); if (clickArray[i].hitTestPoint(mouseX,mouseY,true)) {[code]....
If I add an else it only detects the last item in the array, i.e it always goes to frame 7 unless it's touching the last MC in clickArray. why adding an else statement would cause this to happen? I also tried adding an else if not hitTest...
I'm building a preloader which only loads the background image. This preloader is inside a MyStage class and it's something like this:[code] Remember, I'm calling resultado() on the onProgress function just for test purposes. In theory, it should go on the Completehandler function. Now, when I check if perc is equal to 0, it returns true and loads the image and the rest of content in my index class, but only works with zero.[code]
Everything worked perfectly fine in CS5, then I converted it to CS4 and it won't move my guy around, or even trace anything, when I press the WASD keys. The arrow keys still work fine.
I have to load a text file. First I want to detect if the file exists or not, so I use "if (rawTxt == undefined)".
Now, if the file exists and contains data, the condition n2 is met...it's OK! But now, if the file exists BUT is empty it doesn't meet the condition n2.. It's not "undefined" neither "not undefined" since any trace action accours.
In other words, how can I check that a text file exists...AND that it's empty or not (so that I can add a branch if that condition is met?) Try by yourself with an empty text file named "Favorites.ini".
Code: var loadFavorite = new LoadVars(); loadFavorite.onData = function(rawTxt:String) { if (rawTxt == undefined) {
when I test my project in flash CS4, both the flash player and the authoring tool detect my keystrokes. Is there a way to make the authoring tool ignore key input while testing a movie, since I really only intend the key presses for the movie?
has anyone else found trace() to be much, much slower in CS4?
Apologies for this post, but I am desperately trying to get an email contact for the swiss watchmaker Jean Roulet le Locle and their site is 100% Flash which does not work for me.
When I try that site with IE8 and FF3, the music and animation start, however, when I try to go to the "next page" it gets stuck at 0% loading. In particular when I try to go to the Contacts page. When the page starts it says "Flash 5.0 plug-in" detected which makes no sense to me.
I've spend an hour uninstalling and reinstalling Flash to no avail. If this site works for someone, could you please post their email contact information.
Originally, I wanted to email this difficulty to Adobe, but they are pretty much a secret organization which is hidden from the prying workd.
In my file (AS2), I have a small square at the middle of the page. Diagonally to the right, I have a vertical wall which is a rectangle. Pasted inside my small square, I have the code:
onClipEvent(enterFrame) { if (Key.isDown(Key.RIGHT)) { if (this.hitTest(Wall._x, Wall._y, false)) _x =
I'm working on the following site http:[url]...I'm getting there however the preloader I'm using keeps appearing even when the movie in question has been cached. Is there a preloader solution out there that detects when a movie has been previously loaded so that it won't show the loader bar again. I find it annoying seeing the bar appear unneccessarily all the time.The preloader I'm using is basically this:
onClipEvent (enterFrame) { loading = _parent.getBytesLoaded(); total = _parent.getBytesTotal();[code]....
I need to know how to make a button called Textchange that detects if the movie clip Meditext is playing, and if it is then largetext will start playing and Meditext will stop. But if it isn't playing, then nothing happens.
I've created a simple Flash based menu (ONE frame, 7 layers) with a Keylistener on the first frame of my "background" layer. I have it setup with six links/buttons. Clicking a button opens that URL. And in "Test" mode from the Flash Editor, pressing 1 thru 6 on the keyboard launches the specified link as well.
But after I publish/upload my file, it no longer detects any keystrokes. I suspected this was because the animation was playing just one frame and stopping, but the animation is set to loop. I also tried adding a second frame and adding a "gotoandplay(1);", but that didn't work either.
Code: KeyListener = new Object(); var myKey; KeyListener.onKeyDown = function() { myKey = Key.getAscii();
I worked on a new Flash project, but I cant seem to find a good solution for how I want my objects to collide. In my project I have: a Ball(moving object) and a Floor(not moving).
The ball is positioned over the floor and drops onto the floor through the gravity that is applied with the code.
[Code]...
Is there a way to have a global gravity in flash AS3. In which you could choose what objects you want to be affected by it? Is there a way to have a block of code that separates moving from still objects and will not let any objects collide(not overlap)?

First: the -23 in the code is what I don't like.

What kind of code would one need to check for collisions between two symbols? I am hoping to become a game designer so this is important for future references.
Im currently working on a demo flash game built on AS 2.0. im a very beginner to this flash and AS and im stuck up with a very silly concept though im not able to overcome it. the problem i have is with collision detection ie hit test and im really struggling with it.
I am trying to use boxes for hit collision. I want to be precise with the collision so I was thinking about making multiple small boxes and checking for collision that way. This maybe a stupid idea or a smart one. If I do this way will that affect the performance of the game even though the boxes are invisible and wont be drawn on the stage.
map out the object starting from its center outward. Like right, left, top and bottom. I am creating a flying shooter so the plane has a long wing span. I could also map out the wing span and tail and so on.

suppose I have a set of movieclips on stage. Each movieclips has its own name. I can drag one of these and check when my dragged movieclip collide with the other ones. Is there a way to determine the name of the movieclip that was hit by the dragged one without having to use a for-loop statement and/or array?
I have two particles (mc's) that are linked together to a line. Both particles use xspeed and yspeed when they are moving.
Then to my question.. how will the particles xspeed/yspeed change when the line collide into another movieclip? I know how I can check the collision, but I don't know how I'm going to change the speeds.
Its been many years since I've used flash and I was just wondering what the easiest way to do collision detection was now. I know that there was some hit test bounding box stuff present earlier but I don't know the capabilities of flash cs4 and the advances that have been made. Google searches have yielded things like complex pixel-perfect collision detection but not a lot seems to have been written about CS4 yet.
I am trying to create collision detection between mcs without having to write the code 10 times. I thought this would work but it gives me this error:
TypeError: Error #1034: Type Coercion failed: cannot convert "crisisAnimation" to flash.display.MovieClip. at ImagineServicesText2_fla::MainTimeline/hitTester()
Code: var target_mc:Array = new Array(); var numTextBoxes:Number; target_mc = ["crisisAnimation","eventTextAnimation","mediaRelationsAnimation", "mediaAnimation", "graphicAnimation", "webAnimation", "advertisingAnimation"];
I am trying to get some collision detection working. What I have is a ball moving around the stage. There is a box in the middle which when the ball hits, I would like it to bounce off the box. I can get the x axis working fine using hitTestObject but when I detect for collisions on the y axis, the two axis conflict. Does anyone have a way of doing this properly?[code]
I am making a game and it has falling objects (similar to shooting) and it also has some other random generating objects going to the other direction. So the objects aren't already on the stage. I was wondering if when I spawn them if I could put them in an array or something and check collision between the two arrays or what?
With AS3 I managed to resolve the problem I said in the thread, but now I face a new problem.If you hit the wall, it will register a collision as it should. Goes the same for the exit. But if you look to the upper left, there's a rotating rectangle. If you hit the rotating rectangle, it will register a collision IF YOUR CURSOR MOVED.That's right, if you freeze the cursor in place as the rectangle comes sweeping in, it WILL NOT register a collision, meaning if it were a maze game, people could cheat by just staying still.I forgot, here's the code:
So I've been googling around for information on detecting collisions in AS3 and I found this page which has what troy claims to be a 'pixel-perfect' collision detection algorithm:[URL]..
I've found the BitmapData.hitTest() function very handy, but limited for my purposes. I need to figure out at exactly which point the two images collide (in any coords system,really), since their behaviour will change depending on the angle of the surface hit
i have one ball and one rectangle in my fla file. i have finish to move ball using arrow on keyboard. but i want to check the collision when the ball hit the wall. i just can check the collision on the right side of the wall, the collision isn't work on the left, bottom and the top side of the wall
I am TRYING to get an mc to stop moving when it contacts another mc using hitTestObject and a stopDrag command The probem comes is that I want to be able to drag the mc again, but because it stop dragging while it is in contact with the target I can't move it again.Can anyone tell me how I can stop an mc dragging without losing the ablility to drag it again
function hitMe(event:Event){ if (top_mc.hitTestObject(phone_mc) || foot_mc.hitTestObject(phone_mc) || body_mc.hitTestObject(phone_mc)){ reply_txt.text = "CONTACT"; removeEventListener(Event.ENTER_FRAME,hitMe); body_mc.x --;body_mc.y --;
I have a score system on one of my games, and it involves a dynamic textbox with a bonus system. I want to make it so that when my main character and special objects collide, bonus score is added.This is my code for my scorelayer, instance name of scorebox is (score_txt)
[code]...
There was a bonus code for it but I removed it because I couldn't get it to work with collisions. All enemies/powerups spawn in the middle of the game so they don't have instance names (so I can't do a hittest between my main character (instance name: Thedude) and any enemies (No instance name) )I can do collision test by putting codes in the spawning thing's .as file, that way I can make a collision code without having both parties needing an instance name, but I have no bonus score code to work with. The one I used on my score layer does not work if put in a character's .as file.
