I want to create a function in which I can drag a MovieClip which will bump into other MovieClips on the stage without overlapping them. (i.e. the object cannot be dragged over or through other MovieClips).
function dragHolder01(event:Event):void{
if (mouseDownHolder01 == true) {
for(var m:int = 0;m<blockHolder.numChildren; m++){

Here is a screenshot of the draggable movieclips: draggable movieclips 1. The movieClips, "Pen", "Paper" and "Coffee" must be draggable. ("desk" is a movie clip on the bottom layer that is not not draggable)2. "Pen" and "Coffee" may be able to be released on top of "paper". However, "Paper" and "Pen" may not be released on top of "Coffee" for visual reasons. (realistically, The paper couldn't sit on top of the coffee cup without bending, so I'd rather it not be possible at all)Small note: All 3 raggable items should be capable of being released anywhere on top of the "desk".3. Lastly, all 3 Items cannot be released from dragging with a portion of their shape sticking out of view of the stage as will be shown below.Here are correct and incorrect examples of how the movie clips should and shouldn't be released from dragging.Correct Example of StopDragClick this link to view jpg example Incorrect Example of StopDragClick this link to view jpg example Ideally, when one movie clip is being dragged towards the outside boundry, I'd like it to be released from being dragged once the tip of the movieclip reaches the boundry, so that it does not appear to be half sticking outside of the flash movie.
View 3 RepliesI need to detect collision between my bezier curve (drawn using curveTo method) and a object, the curve is dyanamic and hence the equation changes every frame. I am looking for a efficient method to detect collision between curve and the object.
View 1 RepliesI read the tutorial about Multiple Object Collision Detection. What I want to do is have there be 3 circles and 3 squares. the circles are moving randomly while the squares are stationary. The actionscript would need to be checking to see whenever the moving circles collide with the stationary squares. However, it doesn't seem to be working. I followed the logic of the tutorial pretty closely, by making a separate list for the instance names. Here is the code for the collision detection.

I am creating a game where I have two separate arrays of objects that I need hitTested with each other. I found an old tutorial in AS2 that I modified to come up with this code:
ActionScript Code:
for (var w:Number = 0;w < enemyLaserArray.length;w++) {
for (var R:Number = 0;R < barricade1Array.length-1;R++) {
if (enemyLaserArray[w].hitTestObject(barricade1Array[R])) {

This code executes like I believe it should, but along with removing the two objects, and splicing them from their arrays, I get this error
Code:
TypeError: Error #1010: A term is undefined and has no properties.on the line hitTestObject line. I have had similar problems in other areas of my project, but this time no matter what I try using trace statements I cannot fathom quite what the problem is.
I have almost everything working except for collision with the bricks. This is based heavily off the "Flash Games University" example although several things are changed. When the game starts with brick collection detection in play, and the ball appears the entire thing freezes. I get this error: Error #1009: Cannot access a property or method of a null object reference. It repeats 28 times - the number of bricks. The error seems to be occurring at "var brickRect:Rectangle", according to debug and observing. It may be a scope issue, but what should I change to fix?

View 5 RepliesIts 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.
View 3 RepliesI 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]
View 4 RepliesSo 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]..
[Code]...
HitTestObject seems to check collision of bounddaries of shapes, it seems to consider everything rectangular. Also if one object jumps two pixel and other five pixels on EnterFrame it seems like there won't be any hit detection. Seriously guys what else method do you use, if you use hitTestObject how do you use?
View 1 RepliesI'm making small interactive games in flash to learn AS3,I need to check the collision between the player and the wall which is normally simple using the hitTestObject function.But now I made a wall object totally surrounding the player with corridors and turn, a collision playground so to speak. Now when I use the hitTestObject function to check whether the player is in collision with the wall it tells me it always collides supposedly because the player object is within the bounds of the wall object.So assuming that I'm correct about the error:How can I prevent getting a collision when I'm inside the bounds of the wall object but not touching the actual walls in that object?
View 2 RepliesI'm trying to make a game like Mario. I've made a character which can jump right now, but I've got some problems with collision detection.
I would like my character to jump on a bar, which is placed higher. My collision detection doesn't work at all I gues..I've made a cirle which has a instance name mcMain and I've made a MovieClip of it. T also made a rectangle which has a instance name balkje, I also made aMovieClip of it.
I hope you can tell me what is wrong about my code and what I've to change to make the collision detection work!

I have Object "A" that moves around and collides with other objects. There are hundreds of other different objects it can collide with. The only way (I found) to test for collision is to loop through every other object. That seems rather inefficient considering I don't even know how many objects exists. Other objects are constantly created and deleted. So this loop would be rather complicated.Is there a way for object A to receive what other object it collided with so that I can then do some code on that other object. Any way to avoid looping? I later need to find out how to detect what objects are near (within x pixels or so) of object A to decide with which one to interact. Maybe that could also be used now to limit the test of collision? Or maybe it gives someone an idea of what to try?
View 4 RepliesI am in the process of building a project in which several MovieClips "swim" around semi-randomly, and another MovieClip that appears and expands over the mouse on click alters the frequency of the turns. Do do so, I simply need to change the value of a single variable on the first MovieClip's timeline when the two collide. I am using hitTestObject, but I keep running into errors. The expanding MovieClip does not have an instance name, because it only appears when the mouse is clicked, and quickly disappears.
I am receiving the error 1067: Implicit coercion of a value of type Class to an unrelated type flash.display.DisplayObject My code causing my first MovieClip to "swim" is on that MC's timeline, while the rest of the code is on the main timeline.
I have this problem: I am making a game with flash cs5, and i am coding in as3 i have written some code, that spawns an child (a fireball) from the character position. i made a movieclip symbol on my main scene, that mc is the "parent" for all the enemies that i am adding but now i need to detect the collision between an enemy child and a fireball child, does anybody know how to do that? if asked i can post some parts of my code

I need help with one of my Flash projects,I'm trying to use gskinners shape based collision detection, but for some reason I cant get it to work, but im pretty new to using classes, so I dont understand the structure too much. Can i get a tutorial on how to use the gskinner class? im using the as2 version.heres the code, bare with me, there's a lot here. in all codes, mc1 is the track outline MC, and mc2 is the car
basicly im making a 2D top down version of WipEout HD Fury, so file structure is something like this (the .fla is called wipeout as3 because i was initialy coding in as3 and never changed the filename).wipeout as3.fla (the flash file containing all the MCs and animations, but only enough coding to import all of the external code files, as well as the VCam and its script)
the code is;
Code: Select all #include RaceControl.as"
the RaceControl.as is used to determine the Car's control scheme, and refers to a physics code called RaceCar.as. i found it on the interwebs, all credit to matt carpenter;
Code: Select all// Race control
// Create key listener[code]........
the Bounce Function is my own work, and is what i want to happen when a collision is detected.now, the movieclip used for the car is my own drawn design, as is the track, and i want to use GSkinner's shape based collision to detect the collisions properly. so far i have the car driving around quite happily but i need it to collide with the walls of the track, rather than drive right through them.
I was wondering how you get the collsion detection to be just what is in the MCs instead of a rectangularness of the movieClip.

I was wondering what classes do you use for good collision detection for games and similar, I have used Corey Oneil's CDK (Collision Detection Kit url... and an as3 port of the Grant Skinner method (url...) but here's the issue, with the cdk the problem is that I'm using flashdevelop and the compiler is kind of strict so I have to rewrite a lot of thing that function in the normal flash compiler, the gskinner port has a problem about some null object reference.I was wondering if any of you could recommend me some classes or tell me how do you handle your collision detection.

Is there a way I can drag the the e.target onto the button that the flv will only add to the stage once, even though the e.target remains colliding with the button?I cant have a MOUSE_UP event listener as I already have an ENTER_FRAME listener within the if statement.
View 6 RepliesEDIT :The thread has transitioned into [3d collision detection with as3 ] - check last post I'm in the making of my molehill game, and have now approached a little problem: I have my Terrain and my Mesh(character model). Moving/walking the mesh around was simple enough (X,Z). But when i added elevation to the terrain, i have to add movement in Y depending on the Y pos of the terrains vertices. My terrain does not have a fixed grid, and eventually might not have equal amount of rows per col. The way that i receive the verticeData is through one long vector.

View 3 RepliesI'm having a bit of trouble with psuedo 3d collisions using spheres. I'm using _xscale and _yscale to emulate the z-axis (no horizon point), and am having trouble determining the distance between the objects on the z-axis based upon their relative scales. I'm not concerned at this moment with creating new vectors based upon hit angles, just getting the z-index collision detection working.
(I also need to tweak the code to prevent trapping, so much todo) Here's the code, the issue is how do I determine the correct value for the z-axis in the hittest? note-this only works when I publish in flash6 when using mx2004, the collision detection doesn't work at all when published for flash7?!?

I'm making a basic platformer to familiarize myself with AS3. I'm currently having an issue with the HitTestObject and HitTestPoint methods. Currently my game consists of a character who can run and jump, and a box which should prevent him from falling. I have two questions (the complete code is attached and is only
briefly referenced in the questions):
1) Why is my HitTestObject broken? The issue I'm having is that when I perform box.HitTestObject(character), the screen shakes in most of the character poses (i.e. facing left or right) but not when the character is crouching. I suspect this is because the bounding box in the different frames of my character movieclip are not the same. Is this the case, and how can I make certain my bounding boxes are exactly the same across all frames?
