I think Flash MX pro is Action Script. Anyway, I'm a java programmer looking to create a Flash game. Thus far I have created a class file called Vehicle.as that looks like:
class Vechicle extends MovieClip {
public var vehicle:MovieClip;
private var speed:Number;
private var accel:Number;
function Vehicle(passed:MovieClip) {
this.vehicle = passed;
this.speed = 5;
this.accel = 5;
}
function getSpeed():Number {
return this.speed;
}
function setSpeed(spd:Number) {
this.speed = spd;
}
function getAccel():Number {
return this.accel;
}
function setAccel(acl:Number) {
this.accel = acl;
}
}Basically just accessor methods. Now, on my main flash page, I want to link this class to a movie clip. Also, I want to be able to control this movie clip with the arrow keys. Should the eventhandlers be within the class file? If not, should they be in their own interface/class? How do I link it all together?
Have you ever seen on your facebook wall how it updates without refreshing the page? This is what I want to do I know it can be done with AJAX that is the whole point

Albeit there are other protocols better suited for my purpose however I know this is possible. I merely want to use the setTimeout function to continuously send requests to the server ever 3 or 4 seconds. I've seen it done a few times (I think it's what facebook chat uses).
I'm trying to make a plug in less chat room using javascript php and mysql. Now, the only part I can get to work is to autoupdate the board. Basically I want the board to autoupdate every 2 seconds to display any new messages that may have been posted. The two functions that are suppose to do this are blankReq() and handleBlankReq(). I have posted both my javascript page and my backend php page. The code is self explanatory but just to clarify the mode parameter I send to my php pages tells whether to insert a new message / display the chat log or to just display the chat log. heres the code

It's fucking making me so angry
I need to open a file and find the first instance of a given string. So if I decided to search "the" it would have to return the index of the first instance of "the".
I can't figure this out plz help!

Yea okay so I have an array of movieclips now how to i display those clips on the screen?
....
Ok so I populated an Array with movieclips
myArray = [];
myArray.push(_root.a1);
for (var i = 1; i < 10; ++i) {
_root.firstClip.duplicateMovieClip("newC lip" + i, i);
myArray.push(_root["newClip" + i]);
}
Now how do I write those clips to the stage??
for (int x=0;x<myArray.length;x++) {
myArray[x]. // wtf do i put here?!?!
}
I need to make a 10x10 grid of MC's. Each MC will inherit the same class. I have another MC (a car) that will have a hitTest code to see if it is touching any of t he 10x10 MC's. Is there an easier way to represent these 100 parts of the grid (each its own MC) without creating 100 movie clips and linking them all to the same class?

Can you explain to me how to link a class to an MC? I'm using as 2.0 and I'm familar with oop but in java not flash. How does my MC inherit the class?
I have 10 movie clips which are all identical squares. I want them all to have the same functions / variables. However, i dont want them to act the same. What i mean is if mc1 is clicked I don't want mc2 or mc3 to be affected.
How do i do this
That's the first thing I tried but it didn't fix it. I also added the extends MovieClip but it didnt change anything
Controls.as
class Controls {
private var speed:Number;
private var rotation:Number;
function Controls() {
}
function spin():Void {
_rotation+=5;
}
}Game.fla
var obj:Controls = new Controls();
obj.spin();I have my movieclip linked with Controls.as. The code in Game.fla is on the main time line. Does nothing. When I put it in the movieclip it spins but spins around an imaginary circle(it spins around a center point away from the mc)
HELP
.... and stop putting fucking words in my mouth. A degree is completely different then a HIGH SCHOOL EDUCATION. If you don't have enough "in you" to graduate high school chances are you don't have enough to do anything else in life.
I know a bunch of high school drop outs. They're all (without exception) fucking inbred moron losers

HAHAHA alright great argument this is where I stopped reading.
Like, we all know about shit, but shit when you do shit, shit happens.
hahaha

"College burnout"....
LOL @ whoever said programming wasn't about education. Yea, maybe you can throw together a nifty flash app or a battleship game without any formal education. Programming is about logic and math. I'd like to see a high school drop out write a collision detection engine for a curved surface (integrals). Big O = discrete mathematics. The list goes on and on
I'm really not trying to offend anyone here. My point is that there is a lot more to programming then memorizing functions and learning about classes. Yea, I learned how to code java when I was 15 too. Great! Unfortunately there aren't many employers looking to pay people to write simple calculator and notepad type applications.
Case point: Cryptography
If you think you're going to cut it as a programmer without a high school diploma (at the absolute least) you are extremely mistaken. I'm really not trying to put you down. But fuck kid, EVERYONE graduates high school these days. You're destined to make $10.00/hr the rest of your life.
Think about it. Go back. Get your diploma. NOT A GED. Get your fucking high school diploma. Stop hiding behind this whole "productive" facade.
Ahahaha excuse me for laughing in your face. You dropped out of high school to become more productive? It's like fucking for virginity. You aren't going to have any chance in this world if you cannot finish high school. High school is a damn cake walk kid. At the very least it's a place to make lifelong friends

Did you get it to work?
Also, for all you high school students out there, remember that college isn't always a good investment. Don't go into debt unless you're going to MIT, Cal-Tech, CMU, Harvard, Yale, etc. Go to a community college, save money, and transfer after two years. If you want to live the college life then go to a state school. A $250,000 private school education is no better then a $30,000 education (except for the aforementioned schools). The people who are going to look down are you are the same people who are going to have gray hair in 4 years. $250,000 debt and a degree from Northeastern completely fucked compared to someone with $0 debt and a degree from SUNY Buffalo
You're not alone brother. I'm a computer science major (BS not BA), and my last semester really took a toll on me. I have a serious passion for coding. Learned html/javascript at 13, moved on to php, mysql, actionscript, java, c++, assembly, ect, etc. The math is what kills me. I barely scraped by with a C in calc II. Electromagnetism was the hardest class I've ever taken. Sometimes I feel like I would be better suited for a CIS degree... you know... something a little less challenging.
If you've already payed for 2 years you might as well finish up. If you haven't gone that far I suggest you take a serious look at your life. By now I'm sure you've realized that this industry won't turn you rich. If you're lucky, you may land a nice job that affords you a decent living. Give it 10 years and you might land a job in management. Fuck, I know high school gym teachers that make $110,000 a year (public school, NYS) at 30 years of service. What else are you going to do?
For me, it's just a matter of living. I'm going to really concentrate the next two years. I'm going to graduate and take all I can from this degree. I've realized that life isn't all about making the big bucks, and college isn't all about landing a job. Ideally, I would like to find a wife, get salaried and have a baby or two. CS is just a facilitator
I hope my ramble has helped in some way

Yessir
Yea I forgot to mention you're going to need a dedicated server cause your game is going to be as popular as farmville
I don't have flash installed on my server so I cannot check that line. If it doesn't work (it should...) please try and typecaste them to doubles, not integers.
Next time please phrase your question is a more comprehensive manner. The person above me is totally off. He's looking to find the remainder (using the mod operator). You cannot typecaste the values to INT because INT values don't have a remainder
_root.cashbox.text += (_root.expensivebox.text + _root.interestbox.text - _root.incomebox.text) % 1;I don't even think typecasting is necessary (it may depend on what version of flash you are using). If the following code doesn't work you may want to typecaste and work with variables.
Things you'll need
1. $2000
or
1. Four years (or a degree)
2. Money for books and coffee
3. An artist
4. $300 for flash
5. Change #1 to six years if you want to do it the free way (java)
Good luck and god speed

Ahh radians! Of course I'm so stupid....
Wtf does xscale and yscale have to do with anything I asked?
They're called global variables. I'm not positive, but I believe you can have a variable with a "global scope" (can be used anywhere), if you declare it in the main timeline
