I am doing a flash game with Actionscript 2.0 and have encountered a problem. I have this statement _root.bulletArray = [] that is storing all my movieclips that have been created with attachMovieClip. I was able to store all bullets in the array because when I say for it to trace the array I get the following:

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.
View 8 RepliesOkay, here's the rub. I'm making a little maze game. In this maze game, I have walls. They link to a class called Wall.as. In order to collision detect with the player, I do this:
MovieClip(parent).checkCollisonWithPlayer(this);
Where (parent) is a manager logic class. The parent does this
public function checkCollisonWithPlayer(wall:MovieClip)

I'm using the .unshift method therefore the newest values go into [0] and the rest are pushed down.
What is a good method to remove a value from an array once it has passed a certain length? For example i only want my array to hold 5 values.
Also, is there a method for clearing the entire array, ie removing all values? Or will i have to manually change all the values with a loop?
How do I display the contents of an array in a text box? (AS3) It's a 2-dimensional array, if that matters.
This shows me the first entry, of course:
ActionScript Code:
outputBox.text = bigChunk[0];
This shows me all data in the array, but of course the user won't be able to see this:
ActionScript Code:
trace(bigChunk);
What I want is this, but of course it doesn't work. Gives me an error because I'm trying to use an array as a string.
ActionScript Code:
outputBox.text = bigChunk;
I have a grid of thumbnails that, when clicked, the entire grid is to be invisible EXCEPT the one clicked.

I'm having a problem checking the position of elements in an array.. for example if I have an array as follows :-I have drawn the number 68 (I always exclude the number drawn). I am checking this array of numbers to see if any exist in the same 'row'Say I have already drawn 61,62 and 63. I don't want this to 'return as true' when I check the array because yes the numbers exist but there is a gap (the numbers arSo I would like to accept if I had 68, 69, 70 because they are sequential from 68 but if I also have 72 I don't wish to accept that number.
View 19 RepliesIs there a way of checking all the strings in an Array in one time ex:
Code: Select allvar array:Array = new Array("string1","string2","...")
if(text_field.text == array[everything]){
doSomething()
}
I already tried "for(var i:Number = 0; i<=array.length; i++){ ..." it just doesn't work well enough enough.
How would I go about checking the length of a sub array? If I have a code like this:
ActionScript Code:
a = [["a0","a1", "a2", "a3","a4","a5"],
["a0","a1"]];
and I wanted to check the length of the second subarray (the answer would be 2) what would the syntax be?
Edit: the title should obviously be Multidimentional.
how can I check the content of an array with a switch statement?
Code:
var array :Array =[0,0];
switch (array) {

I'm trying to do something such as:
Code:
var n:Node = openList.shift();
I know that all of the data contained inside openList is a type of Node object, but Flash returns an error. I don't know how to typecast such as placing (in another language)...
Code:
(Node) openList.shift();
...to tell Flash that the data returned will be a Node object.
Better yet, is there a way to specify, while declaring the array, the type of the data that will be placed in it?
I could just take the :Node tag out from my variable declaration, but this might be in a tutorial, so I should at least act like I believe half the stuff about proper coding I write about
I have a string, and I have to check if this value exists in an array, but it inside an IFI dunno if I explained well..

I am trying to get a collision between an array of movieclips but it isnt doing well =S.Here is where I am now:
[code]....
This code works, but it is only colliding with one object. I have made an Array called: _root.enemyArray.I have tried to make an for statment inside the current one without sucess.
I'm trying to check through an array to see if any of my movie clips are currently on frame 15, before taking giant leaps I was trying to just get it to work with one var in the array before all of them, for some reason this code is not working, the trace is not coming up.
Code:
stop();
var anybtn:Array = [btn1_mc, btn2_mc];
trace(anybtn[1]);
btn1.onPress = function(){
if(anybtn[1]._currentframe == 15){
trace ("Array Check Working"); .....
If someone would like to go a step further and show me how to check through all movie clips. There will be many more than btn1_mc and btn2_mc so I will definitely need to use an array.
I have an array that has its values dynamically changed as a user interacts with buttons. I need to constantly check 6 index values from this array against each other so that if they are the same value they count as 1 but if they are unique they also count as 1.
E.g. IF all 6 index points = "A" I get 1 returned
If 3 of the index points = "A"
2 index points = "B"
1 index point = "C"
I get 3 returned to me
So I'm looking for a way to get a number returned to me ranging from 1-6 depending on the values.
I have this Array
Code:
var shoprubriken:Array = new Array();
shoprubriken[0] = "43";
shoprubriken[1] = "44";
[Code]....
Now I wanted to check on which Index Position maybe the 47 is
How can I archive this on a Button or Function?
I have a mixed Array, containing instances of a custom Image class, and of the FLVPlayback class.. I want to be able to loop through the Array, and check whether each element is a video or an image?
View 2 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)) {
[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).
If 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'm trying to have an enemy's shell hit my player. I have the logic in place that detects a player's bomb hit an enemy, I tried to edit it slightly and apply the same logic to the enemies shell.

I have an array. I have a button, when I press on it I want to be able to loop through every item in the array and see if EVERY item is equal to true, if so I want something to happen.
var allIsTrue = false;
_global.myArray = [false, true, false, true, false, true, false, false, false, false, false, false, false,false,false,true]
///would not do something
[Code].....
I thought I could loop through each one and if a false statement if found, the loop stops and the variable allIsTrue = false. But if the loop cycles all the way through allIsTrue = true.
I have an array of points that I will use to generate a closed polygonal fence on the outside of a game stage (2D). I wish to have collision detection between this fence and a bouncing ball-like object on the inside. Additionally, I would like to be able to arbitrarily add/remove/redraw the fence in realtime and have the collision detection still operate realistically. I have considered drawing a Sprite/Shape from the points and doing a HitTest at each frame to check whether to bounce or not. My question: is this the best/correct way to accomplish this goal? Consider something like JezzBall with diagonal lines of any angle a simulation of what I'm trying to do.
View 2 RepliesI 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])) {
[code]....
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.
a little while ago I saw something on this website:[URL]...I decided I wanted to recreate something like it.
They're using javascript, I'm using ActionScript, anyway.I'm trying to create collision detection for an array of movieclips inside a for loop. Right now I have it that upon holding down the mouse, the same movie clip will fall onto a ground object (and bounce up occasionally,) I'm trying to make it to so each ball could stand on top of each other. I've used collision detection before for separate objects, but never for instances of the same object inside a for loop.
Im a bit stumped on this. I have a movie clip named mcMain that the player controls, and i want him to have it detect collisions at certain points of the screen (like at a certain X and Y co-ordinates). I have an array that contains those values, which is shown below:
Code:
//Array that holds x position of points
var xPoint:Array = new Array(150,400,200,300,100);

I am recently working with an application. Where I need 4 unique values from an array in such a way that it should checking random item every time. For eg:-
Main_Array = ["one","two","three","four","five","six","seven "];
Sub_Array = ["three"]; // initially it holds one value
for(each value of Sub_Array)
[code]........
I am trying but I don't get unique values, or something gets wrong which I am not able to solve. Looking forward desperately for some help
[I apologise if this isn't really an in depth question, but I wanted to solve this once and for all]I was trying to get look into quadtrees, but already ran into trouble getting collision detection without any optimization working properly. Did a search and found a pretty neat example:Only some collisions are detected between particular objects. When the objects are not moving it seems to work alot better for some reason. really can't figure out whats the problem, the code is essentially the same as the sample. I did not blindy copy pasted it, I understands whats happening except Here is what I did:Main class

import com.martino.objects.Square;

I am trying to test the collisions between a bullet and an array of enemies in Actionscript 2. However it is not sensing a collision.This is the code in the bullet.

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]
