My collision detection is solid when I put 2 images against each other but when I put 1 image against another image's child I can't get a collision. Whats the deal? Do I have to add the child independently of its parent?
View 3 RepliesSo in my game, every 'enemy' movieclip creates a textfield that represents the name of the enemy. The problem is, I want my collision detect engine to detect a collision with the enemy itself, not the textfield. This is the code that I have currently have on my collision class for detecting a collision with the enemy:
for(var i = 0;i < _enemies.length; i++)
{
if(CollisionEngine.isColliding(_laser, _enemies[i]._enemyNameTextField, _animation))

I want to detect when a circle collides into a random object. I know this is pretty basic to do with a mouse colliding into a random object but I want to modify this for a circle. I have seen some examples which use circles but they are drawn in script, is it possible to do this with a mc from the library.
View 2 Repliesim creating a circle dynamically with each click on stage, with the drawCircle function, now, that circle is a shape, not a movieClip, im arranging this circles inside of an array, and i want to check if they collide, so that second circle dont appear if its occupying the same space as the last one, or at least trace if they are colliding so i can do something about it....
i've made tests with movieClips and no problem, the mc1.hitTestObject(mc) works great but not so great with raw shapes, it just ignores collisions
Is there a way to detect what movie clip is in a certain location? For instance, if I enter some random coords, like x=15, y=0, is there a way it will return the name of the movieclip thats occupies that location?
View 1 Replieswhat i am trying to do is to detect a collision between an empty mc and an mc allready in stage.the empty mc is a line, which I draw with the mouse. when this line hits the other mc I want the colission to be detected. so far it doesnt work properly.the colision is being detected even if the line that i draw, doesnt hit the other mc. does it have to do with the properties of the empty mc, or the hittest method has to be changed?Here is the code:
_root.mc.onEnterFrame=function(){
if(_root.mc.hitTest(_root.line)){
thingstohappen;}
Because I want to detect collision between a point and an MC contained within another MC.
View 1 RepliesTake a look at this scenario, I have two characters, one shoots two bullets on the direction of the other character, the bullets are fired instantly and travel at infinity speed, how to detect a collision? Here's an image to illustrate the problem: The red bullet would clearly miss, but the green bullet would hit, how to perform this kind of collision test?
View 1 RepliesIf you have a group of movie clips stored in an array and the movie cliops are placed on the stage randomly, and use your arrow keys to move a box on top of one of the movie clips - how can you "tell" Flash which movie clip you clicked on?
Right now I've got a for loop going which loops through the array that has stored the movie clip instances, presumably the hitTestObject would eventually get a hit...But this doesn't work, especially inside an event handler where when I press the right arrow on my keyboard.

i have two movie clips mcTrap and mcCharacter.how can i detect collision (character is fully inside) over the trap door?
View 1 RepliesDoes anyone know how to use hitTest with two movieclips so that it would detectthe collision of the visible part of the MC, not the **** bounding box???
View 2 RepliesRight now I'm working on an advanced hitTesting engine, and What I'm trying to do here is create an engine that will detect collision with one object instead of two. That basically means that if any other objects touch this movie clip, the hitTest will return True. Right now the .fla containing the engine has nothing but a circle that can be moved using arrow keys and 8 squares that disappear when touched by the circle. Obviously, I could do something like:
if (circle.hitTest(square1)) {
do so and so
} else if (circle.hitTest(square2)) {
do this and that
} etc...
But that would be too long, since the engine has to be able to contain 100 squares without too much change in the code.
i am listening contact between dynamic bodies. But cannot listen contact between dynamic and static bodies .
I can handle collision detection on my b2contactListener class with this metod.
public override function BeginContact(contact:b2Contact):void {
// getting the fixtures that collided
var fixtureA:b2Fixture=contact.GetFixtureA();

I got it working for using the e.target of the mouse but now I need to filter through the array on enter frame and detect whether a collision is detected.[code]
View 4 RepliesIs there a way to test collision with a child of an object?eg.
ActionScript Code:
obj1.hitTestObject(obj2.childObj1)
obj1 and obj2 are on the same level of hierarchy.
I am trying to test when an object collides with a particular location of another object so i made a 1x1 movieclip (childObj1) and placed it inside obj2 at that particular position.
I am building a tile based game, in which the player can digg away at all the tiles.The problem im having is that my collision detection code for the tiles only will detect a collision with the first tile placed, or any tile required i explicitly code its number in.
In all other examples, tutorials and code, this should work, and yet it does not on mine.heres the specific code , the array the cildren are stored in is called dirt, as they are dirt tiles.
ActionScript Code:
for (var m:int=dirt.length-1; m>=0; m--) {
forval.text=String(m);
if (dirt[m].hitTestObject(_player)) {
[code]....
this brings me onto another problem i am having, which is that now that the collision code is inside a for statement, the above code doesnt work correctly. normally the lastx and lasty should be recorded , and if there is a collsion, the player is shifted back to the last position there wasnt a collision.for some reason now, even though it should be looping faster and detecting the lasx and lasty even faster, it isnt, and although a collision is detected (only with child 0).
I've encountered what seems to be a race condition between a parent and its child movie clips, but I don't know what to do to fix it. The parent movie clip is on the stage at compile-time, and the clip contains a number of children. In the parent's constructor function I have the following code
for(var i in this){
if(this[i] instanceof MovieClip){
this[i].hval = this[i]._x;
$tItems.push(this[i]);
this[i].subscribe(this);}}
I'm able to give every child an hval property and push it into $tItems, but the call to the child's subscribe method fails every time. It's as though the child's functions haven't been loaded because the children haven't yet realized that they're members of a class that have a subscribe function. I set up a button to test this function call manually and when I do it that way I succeed in calling the subscribe method in all the children, so it really seems to be some sort of race condition. How can I overcome this?
I have a parent.swf file that loads a child.swf. When the child.swf is running on it's own, I'd like it to do one thing, but if it has been loaded into the parent.swf. I want it do something else (i.e. change behavior). Is there a way for the child.swf to detect whether it has been loaded into a parent.swf or not?
View 4 RepliesI have a parent movieclip with a few other movieclips inside it. When I add a mouseclick eventlistener to the stage and click on one of the children, i want the target of the event to be the parent movieclip. I still need the children to be mouseEnabled.
how do you check if a movieclip is a child of another?
I have XML that looks like this:
<question>
<type_elt>
<opt_out_flag />
</type_elt>
</question>
type_elt is not an element name; it might be <single>, <multiple> or something else, determined at runtime. How, given this, can I detect the presence of the opt_out_flag element?
I tried this (where xml refers to the question element):
if (xml.*.opt_out_flag) {
do_something();
}
but even in cases without opt_out_flag the above expression returns true. Obviously I'm missing something, but what is it?
The problem is, i need to detect the quantity of movieclips that a child movie clip is over A movie clip is over several boxes and that boxes are MC, in the image for example when i drag the child MC, this is over some movie clips but i cant detect which movieclips are.

Is there a way to detect if an image from a folder was copied to the clipboard?
View 1 RepliesI am trying to load an image from an external source and then get the _x _y _height and _width of the movieclip that I have loaded the image into.
I have successfully loaded the image into a movie clip but because of the way Flash works I can not pull up the attributes of the movieclip.
I use attachMovie() to create a new instance of a movieclip, then I use loadMovie() to load an external PNG image into the new movieclip. That is working fine.
I want to be able to detect when the image has finished loading into the movie clip container. I need to detect this because I want to check the image width and height.
If I check the width and height right after I call loadMovie() it is returning the default placeholder size, instead of the new loaded image size. It obviously has not finished loading when I check it there.
I am using Flex to create a sort of photo viewer that loops through an array of photos when users click on arrow buttons. However, I wanted to make it so if an image is broken then it would be skipped, but I can't seem to find a way of checking if the image is broken.

View 1 RepliesI am have a enemy with a sword on 1 image and a player character on another.I test to see if the tip of the enemy sword (point) appears in the player image.
It seems to always detect a hit on the image when it doesnt hit it. The player image has a lot of transparent pixels and it looks like it detects a bounding box hit.Not sure what to do here as this test looks faulty. The y values are correct but the x values seem to cause th issue where xVal is the currect image x value.
x=enemy.xVal+el.x ;y=posY(enemy.yVal-el.y) ;
if (myplayer.img.hitTestPoint(x,y,false)==true)
