ActionScript 2.0 :: Trouble Grasping Square Brackets
Aug 10, 2007
I'm reading a book on ActionScript and I'm in the section on controlling movie clips. I'm reading about the basic methods, and I'm starting to realize I still don't fully understand the significance of square brackets.[code]Obviously, this is the prototype form of the lineStyle() method. What I don't get is why "thickness" is the only parameter without square brackets. I know that square brackets are used for retrieving data from an array or object, but either my book doesn't cover why they're used like this in a method, or I just completely blanked it out.

I'm trying to do that trick where you make a variable name with square brackets. I think I don't fully understand what I'm doing though...
Code:
var cursorDirection1:Point = pt.subtract(rootpos1);
var cursorDirection2:Point = pt.subtract(rootpos2);
var farShoulder:int = 1;//1 = left 2 = right
[Code]....
I'm trying to avoid having to do a conditional to choose between cursorDirection1 or cursorDirection2. My last line there isn't working, I'm not entirely sure why. Assuming farShoulder is 1, the code should be interpreted as
Code:
cursorDirection1.normalize(findNormVar(cursorDirection1));
but I'm getting errors about the input being undefined.

I'm stuck with trying to target a movieclip dynamically from a loop. I'm using the square brackket syntax but I can't figure out why it's not working. Here's what I'm trying to do:
Code:
this.t1.t1._alpha=20;
And here's how I'm trying to do it:
Code:
this["t"+1+".t"+1]._alpha= 20;

I have some classes stored in a swc which I would like to instantiate using data pulled in by xml - using a string to reference the classname.So where I would normally use
ActionScript Code:
var tagline:Sprite = new Tagline1();
I would now like to do something like
ActionScript Code:
var tagname:String = "Tagline1"; // really the string comes from XML
var tagline:Sprite = new [tagname]();
I have a vague idea this is possible using square brackets, but I don't seem to be able to find out anything about it.

I have this game, and some levels have a moving square as the player, you move the square with your arrow keys.... I want to have an enemy square that chases the player square.... They only chased mario when you didn't look at them? Kinda like that...... but in this regards:
I only want the enemy square to chase the player square when the player square moves.... soo say the player square moves 5 pixels per movement (know how to do all that), I want the enemy square to move when the player square moves..... towards the player square at like 7 pixels per movement..... so eventually you won't be able to avoid the enemy square....

In one particular keyframe, I have five buttons on the left hand side of my stage, that when clicked, display an external swf on the right handside. It works perfect fine using the code below. However on this frame where all this is going on, I also have a back button that i want to link back to the home page. But I just CAN'T seem to get it to unload the external swfs as well as go back in the timeline.[code]

FLA in CS3 attached.Simple MC with over/out and onPress.All silhouettes have over/out. Silhouette on left initiates the animation.Black box in top left corner resets it.When a silhouette has been rolled over/out it does not follow timeline animation.{Rollover a single person then click left person to see issue.)I originally had the motion done in AS, but switched to timeline for trouble shooting.I'm trying to use more AS than timeline lately, so i hope someone can point me in the right direction. Also any tips in easier ways to do what i'm doing would be great... sometimes i feel like i'm taking the extended route.[code]

i try to program a little shooter game and right now i would like to implement a piece of code, which causes an enemy, as soon as it was killed, to explode. This explosion should then kill and remove all remaining enemies on the screen.
This code is embedded in a while loop, which checks bullets vs enemy collisions, which is on its part embedded in a timer function.
Of course i was looking this error up and it seems, as if i was trying to remove the displayobject enemy although it no longer exists, but unfortunately i can't really figure out what i did wrong.
I bolded the removeChild command which causes the error.
Code:
var avatarHasBeenHit:Boolean = false;
var enemyHasBeenHit:Boolean;var i:int = army.length - 1;
while ((i > -1))

I'm working on an interactive map of the united states in which each state is a button inside a movie clip. The states get larger and move up in depth when you go over them then shrink back down when you mouseout. All of this (finally) is working right.I wanted it to work so that when you clicked on a state it sent you to a seperate page for that specific state..[code] with a seperate link for each movie clip on the stage of course. Now, when I test this in Flash it opens up an explorer window for every single state when I click on one.When I put the swf on a website and use it, each state I click on links me to California for some reason.I'm sure it's just the syntax and then way I'm setting this up but I don't know of a better way to do it without having to redo tons of my actionscript for each state. If anyone knows a quick solution or a better approach I would appreciate it!

i have a few buttons that use loadmovienum to load a few clips into levels. The code on each button is something similar to:
on(release){ loadMovieNum("print_index.swf",1);printbutton._visible = false;webbutton._visible = false;illusbutton._visible = false;threedbutton._visible = false;retouchbutton._visible = false;}
But because the print_index movie slowly scrolls across the stage rather than immediately replace it, there is a moment where the button turns completely invisible after the click. Perhaps the bigger problem is that it doesnt make any of the accompanying buttons invisible like it is supposed to- only the one that is clicked.

I have to send information to an external vendor using their existing parameters. However, they have included brackets [] in some of their variable names. As you might expect AS3 can't resolve the variable name. Does anyone know a way around this?

Let's say I have a function in a class with two required parameters and two optional:
Code:
public class Person extends Sprite {
private var haveToWork:Boolean;
private var hoursOfSleep:Number;
private var gotANewVideoGame:Boolean;
private var gotAHotDate:Boolean;
[Code] .....
All of that setup for this question: on the second call of the areYouHappy function, how do I keep the gotANewVideoGame variable from having a false value assigned to it?

I have a text file that needs to be parsed correctly. The text file looks like this:
[header]
[header 2]
[ header3 ]
I can grab these headers by doing so
var expression:RegExp = /[ [a-z0-9 ]+ ]/igxm;
var items:Array = text.match(expression);
But I would also like to remove the white space from before and after the brackets, so the headers can align against the left edge. Also, for [ header3 ], I would like to remove the white space inside the brackets, before "h" and after "3". What would be the correct regex for something this?

I have five simple equations that I need help converting to ActionScript. I'm making a small "calculator" that takes input from the user and displays a number representing the result of the equation. They're two sets of equations: 1) three-scenario fee calculator to compare the annual costs (X) of renting versus buying equipment; 2) comparison of two rental plans. The numbers entered need to stay the same - the alphabets represent what the user will input. The equations are as follows:
Scenario 1:
X = ([A � F] / G) + H + I + J + (K x 12) + ([L / N] x M)
Scenario 2:
X = ([B � F] / G) + ([E x C] / G) + H + I + J + (K x 12) + ([L / N] x M)[code]....
I've looked at my resources at hand, but my brain just shuts down when I see numbers and letters representing numbers. I do speak three languages fluently, so I (think) I make up for it.how to properly assign the correct order of events (brackets first, etc) in ActionScript to reflect the equations above.

I am trying to pass a variable with brackets in the variable name. Example
productoption[]="value";
Whenever I publish the file flash gives me an unexpected "]" error code. Is it possible to have a variable name with brackets? I tried to use the escape codes %5B%5D to pass the brackets but that didn't work also.

I've been using flash for a whopping 3 days now, and I've stumbled onto a problem that I can't seem to find a way around. I'm using flash 4, due to the fact that #1 it's all I've got, and #2 the new flash mx 6 won't run on the old ass computer I'm using. This is my problem: I import a .bmp image and edit it in flash to make portions of it animated. The image is a symbol (I think it has to be anyway to animate it...) Everything runs fine when I use the basic play/rewind buttons to test the animiation, but when I make it into an executable, or when I go to the menu and hit "Test Movie", the image shows up as a red square. The animation I added still runs, but the actual image I imported is a red square.
