Simple Actionscripting

In this tutorial you need:
Flash MX

Well this is about making an object moving through the scene!
Not with Motion Tween - With Actionscript(AS).
So let's begin!

Step I
Make a new Flash Document.
Create a ball with the ellipse tool.

Step II
Now this is where the fun begins!
Select you ball and make it a Movieclip(MC) by pressing F8 on your keyboard.
Name it like "Ball" or "Circle" or something(doesn't really matter).

Step III
In the bottom on your workspace it should be a tab called "Actions - Objects".
Click it.
Now the tab should "pop" up(not like a internet pop-up).
Click on your ball and write:

Code:

---

onClipEvent(enterFrame){
 * * * this._y --;
}

---

So time for some explanation!

Code:

---

onClipEvent(enterFrame)

---

What this does is that it enters a frame at the frame rate that the user specified(you can see it under your timeline http://img31.imageshack.us/img31/1039/15xu.gif).
Double click it to change it(i recommend 30FPS).

Code:

---

this._y --;

---

The code above says to the object to move to the direction Y-, and that is Up.
I'll show you how it works in Flash.

As you can see, the Flash way, Y Directions is Mirrored.
I don't really get that myself, but i can live with it. :lol:
So test your movies out and have fun!
I hoped you learned something!
Til' next time! B)

good job, i think i got enough in my brain to figure out how to use flash mx on my thanks alot for your help.

lol i had a tut on how to make realistic gravity, but it's been so long since i've used flash i can't remember...lol ill work on it tho

The thing you need to know is math..
I know how to make a Physics engine.

so do i...i just can't remember at the moment lol...anywayz i have to leave for a concert right meyaw so c ya

cya
[kinda empty so i'll add this]

Hmm, good tutorial for beginners, though it is very simple. I'd be interested in seeing that physics engine. Also, you were wrong on the x & y axis. Flash doesn't mirror it, it just mirrors the Y axis. You are wrong on the x axis normally. The x axis always goes from left to right, ascending.

The flash(i like calling it like that) mirrors it. In visual Basic(in my understanding) X- Is left. In flash it is X+.

And as the title says; Simple Actionscripting.

I wasn't bagging on you for it being simple, thats fine, you don't have to defend yourself. And i don't know about visual basic, but in normal, real life, X+ is going to the right. Think about algebra 1, remember plotting graphs and stuff? Heres some links

If you still dont believe me, just go to google and search "X and Y axis".

um.. test it for youself.. if you write :

Code:

---

onClipEvent(enterFrame){
        this._y --;
}

---

It's going up... and those algebra graphs show that y- is down... test it and you'll see...

We misunderstood eachother.. hehe and i wrote wrong above your post... hehe...
Sorry.. :unsure:

No no no, you are completely right there, it was not the Y axis i was debating, that is mirror of the norm, but the x axis is the same on flash and normal. That's why it struck me as odd when you said normally X+ goes left.

Yeah that was what i meant :lol:
I wrote wrong before...

nice man!

nicew tut man! Well done ^_^

RAb B)

I think i'll make a new one soon.
In like 2 Months or something.

I know this thread is already dead but:
Can anyone make a tutorial for 'n00bs' because that tells people what to do but doesn't really explain what we are doing because if i went to do that on my own i would be screwed because i wouldn't know what to do :lol:
Or any links people know?
cheers

I'm back!

Well, you cou'd read the tutorials and guides that comes with your flash software.
It is really easy to get working with flash if you read about the basics.

Cheers, 1337Elite. ;)

hm i'm still figuring that out in my brain :blink:
but it works!..... :P thank's so much....somehow i do understand your explanations better then on other forums. i'm glad you posted things here and explained them. :D

Here is the old cartesian plot graph. (for anyone still wondering)

Note the y axis:

Now here is the new flash version of the cartesian plot graph:

http://www.solarisdesigns.net/images/cartf.gif


To go just a bit further in-depth, this is actually what the Cartesian coordinate system looks like in flashon the root timeline. It will always start in the upper left hand corner on the root timeline. Note that any object defined by the Cartesian coordinate system uses points whether it be a single point or a box with 4 separate coordinates for each side of the box. The top upper left hand corner in flash has the coordinates (0,0).

This is actually what the Cartesian coordinate system looks like in a movie clip in flash. For example lets say that the orange ball is in a movie clip called ball. The center of the orange ball would be at (0,0) in the movie clip if the ball graphic was center inside of the clip (demonstrated below). The exact center of this ball would be at (0,0). We could go on to define the balls height and width by measuring the distance the ball covers along the y and x axis.

Hope that helped :_)
