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

).
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)

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

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:
