wait!

char.x -= 5;

or

char.x = char.x - 5;

would you be interested in a small "bare bones minimum" tutorial on a few game designs?

It's moving
but only left, the d isn't working, do you know why?

I figured out the -= a minute ago, when I typed wait!, but the d won't work right, and yes I'd be interested.

I wish I knew you in person

skimming back the last few pages you only have A programmed you still haven't added the D press event

it needs to be both key pressed and key depressed

switch (e.keyCode)
{
	case Keyboard.A:
	{
		aDown = true;
		break;
	}
	case Keyboard.D:
	{
		dDown = true;
		break;
	}
}

okay I did it

nice, I made a little thing on recording software HERE if you want to check that out

anywho... I am working on putting together a sample. It will be targeting both flash and flash develop, or pretty much any program that uses as3

it will include
- working with sprites
- player and AI (simple)
- collision
- timer and score

Does this sound simple and interesting enough to you?

Check out my new player!;
package
{
import flash.display.MovieClip;
public class player extends MovieClip
{
public function player()
{
this.graphics.beginFill(0xfff000, 1);
this.graphics.drawRect(this.x, this.y, 10, 10);
this.graphics.endFill ();
this.graphics.beginFill(0x000000, 1);
this.graphics.drawRect(this.x + 3, this.y + 7, 5, 2);
this.graphics.endFill ();
this.graphics.beginFill(0x000000, 1);
this.graphics.drawRect(this.x + 7, this.y + 2, 2, 2);
this.graphics.endFill ();
this.graphics.beginFill(0x000000, 1);
this.graphics.drawRect(this.x + 2, this.y + 2, 2, 2);
this.graphics.endFill ();
this.graphics.beginFill(0x000000, 1);
this.graphics.drawRect(this.x - 1, this.y - 1, 12, 2);
this.graphics.endFill ();
this.graphics.beginFill(0x000000, 1);
this.graphics.drawRect(this.x, this.y - 4, 10, 3);
this.graphics.endFill ();
}

}

}

now I want to put a shark in, using the arrow keys, how do I do that?

Okay, i almost have the shark in there, but there is one error on the line that states public function main void (the second time), what is wrong?;

oops, I copied that line wrong somehow, it's actually public function Main():void

if you are working with an img then there are a few ways to get it to appear on the screen. You can blit, copyPixel, or a simple addChild, just to name a few. The methods vary, but the general direction is embed > declare > addChild. Once you get the img to appear then the coding is exactly the same as the A and D buttons, but it will include a bit more to animate the shark.

EDIT: oop ninja'd I did not see your 2 posts there

I'm not putting an image in.

oops there were a few things I didn't put in, but it still won't work;
