Is 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.
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 have a ball in a page and a stopwatch.
The stopwatch works fine starts on page ready.The ball moves using the arrow keys.
But i am just wondering how can I create some kind of boundary, (which will be the size of the page) which when the ball collides with it or goes out of the page the stopwatch will stop?[code]...
I'm having a problem with a hitTest that I'm not sure how to correct. Long story short, I have a box that is added to the stage and beings to tween down to the bottom. If the user presses the left arrow to catch the object before it leaves the stage, they get 1 point (hooray!).The issue that I'm having is this...multiple instances of the same MC are supposed to be added to the stage by a timer but because of how I've set it up, they all have the same instance name. That leaves me with one of 2 options. I can get the hit test to work, but only 1 instance ever actually shows up or a bunch show up, but the hitTest fails. How can i add multiple instances of the same object, but still be able to determine if one of them is overlapping the box when the user hits the arrow key?[code]
View 3 RepliesI'm making a map creator for a tabletop game. The idea is that the map creator would consist of a 48x48 grid and would allow people to drag items onto that grid and save the positional layout of objects like trees and buildings.So I'm working on the very first steps of this and have written the script so far to dynamicaly generate a 48x48 grid and created a test object to be dragged called "follow".
The dynamicaly generated MC draws from the "grid" MC from the library which consists of two layers; the outline of a box and an MC named "grid_bg" which contains a coloured square (set to the same size as the outline). This is all placed into the "container" MC which by default is empty.This part I get working fine.the "follow" mc is set so that it can be dragged on a mouse click.Now the idea is that if a hitTest is run to see if "follow" is in contact with any of the "grid_bg" MC's and if so, run code (i.e. hide or show the grid_bg mc).
This is where I am encountering problems. If I set the hitTest into a layer within the "grid" MC, it only runs the hit test when the movie is first loaded and ignores you dragging and dropping the "follow" mc. If the hitTest is placed into the actions of the "grid_bg" MC and used in conjuction with an IF statement, it seems to act like there is a collision on every box generated.Code to generate the grid:
Code:
//make textboxes
count=2304;

it's easy to test collision between two squares. how do I test the collision if they are rotated?

View 3 RepliesI 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)) {

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).
So 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))

refresh my memory of how to test if a SWF has been loaded into another SWF or if it's the main SWF?
I remember it being something like:
Code:
if (stage == root) {
// Not loaded into another SWF
} else {
// Loaded into another SWF
}
I have a Movie Clip and Im trying to do a hit test on it but i want it to test when the second object touches th eactualy object in the movie clip, not just enters inside of the blue outline.
View 3 RepliesHow can I test if my AS3 code is executing from root or from a child mc that has been imported into a larger project via the loader class? Details:I've got a tutorial that is published both as a standalone projector (exe) and as an swf imported at runtime into a larger project. If the tutorial is running by itself as a standalone projector it needs to execute a few fscommands and perform some other housekeeping chores. If the tutorial is running as a child of the larger project these chores must be skipped. I canā't test Capabilities.playerType because the parent can also run as a standalone projector. It's simple, but here's what I had before I realized the parent might also be standalone:

I am currently creating a game in which the character is stationary in the middle and the world moves in relation to the character. When the character is not moving and not touching anything, I need the world to shift upward to meet the character and stop on collision detection. The problem is I have no idea how to conceptually make this work.
making assets "fall up" and stop when colliding with an object (basically reverse gravity).
I have three objects in the main scene (so far), one of them is draggable (up and down only), then the animated one that moves downwards and the start button (activates the animation). So I've been trying to figure out how to script the collision detection for the first two? The collision should take place not because I dragged the slider onto the animated block, but because the falling piece hits the slider after I pressed the start button.

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.
Right 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.
so I have a function on the Main Timeline that creates an instance of the class Ball once every 60 frames (1 second). In the class code for Ball I have this:

As you can see, I am trying to make it so that if two instances of the class Ball collide, then it should output "STOP". But it isn't working.

Right now I'm trying to make a sliding puzzle. So far I have a block which I can click and drag around, and a few walls which are the boundaries. What I'm trying to do is make an area where the block can slide within the boundaries. So when you try to drag the block into an direction it will stop, whether you got mouse_down or mouse_up. My script so far
Code:
stop();
//Sliding Blocks
MCBlock1.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);

Also I need to use a lot of boundaries, so if there's a way to apply this script easily to several objects
