Hey guys, I need a little help, google isn't answering my calls...

I need to have some MCs face towards a certain point on the stage when they're added. Can anyone share the math required?

For example, movieclip "Enemy1" is added to the stage at 800,600. I want it to rotate to point towards 400,300.

I'm trying to pass a URL from a text file to flash. It gets there, but when I use it, it uses it as a string!

Here's what happens....

It reads this from the file :

imageURL=pictures/images/

Then when I tell it to load a picture from that directory, using this method :

URLRequest(path + filename); , where path is imageURL.

and it says URL not found. I had it trace it, and the path was fine. I entered the same path into the string manually, and it works. I have no clue why it won't work..

Cool site.. I'd join, but I'm afraid college leaves no time for recreational flash :[

Have some vars in a text file, having a little problem with a string.
Here's my code :

for (var n = 0;n<totalFiles;n++)
			{
				var temp2 = ("loader.data.img" + (n+1)).toString();
				descArray.push(temp2);
			}
			trace(descArray);

When I do that , my array looks like :
loader.data.img1,loader.data.img2,loader .data.img..blah blah blah

That's expected, because I'm pushing the string... Question is, how would I make it not add the string itself, but what it's pointing to? I think I'd have to convert the string to something else, but I have no clue what would work

Most of the "baww AS3 is too hard" complaints stem from users being too stuck with typical AS2.0 newbie mindedness (no type declaration, no OOP, using onClipEvents, etc). If, and only if, you had used AS2.0 properly, moving to AS3.0 would not be problem.

So why even bother with AS2.0 when you can go straight to AS3.0?

This. Move onto AS3, and you'll pave the way for yourself to learn other real programming languages. AS2 is a freakin joke.

OK, so I got a button that acts as a replay button.

On the timeline I have :

stop();
replayButton();

In the document class I have :

public function replayButton()
		{
			something.statDisplay.text = something.toString();
			button_replay.addEventListener(MouseEvent.MOUSE_UP, replayMovie);


		}
		function replayMovie(e:MouseEvent)
		{
			trace("dsakljdla");
			gotoAndPlay(2);
		}

It traces, but for some unknown reason it doesn't go to frame 2 again. Any ideas?

Change the value of UI.statText.text to person.stat.toString();

In class "person" I have variable "stat", which is a number and equals zero. In another class I have this function :

UI.statText.text = person.stat.toString();

I get this error :

TypeError: Error #1034: Type Coercion failed: cannot convert "0" to flash.text.TextField.

I can't figure out what the hell it wants. I've tried everything I can think, and am about to stab something. And yes, I've imported flash.text.*;

Didn't work =(

But I did manage to find a temporary solution :

while (!doc.ground1.hitTestPoint(this.x, this.y+50, true))
				{
					this.y+=1
				}
			
			
			while (doc.ground1.hitTestPoint(this.x, this.y+30, true))
			{
				this.y -= 1;
			}

I think it's terrible though. If anyone can come up with a more elegant one, please do so <3

oh, i forgot to mention, the code you see is the 'gravity' code.

So I'm trying to make a platformer...

RIght now I have an ENTER_FRAME listener that does this on the "player" :

while (doc.ground1.hitTestPoint(this.x, this.y+50, true))
			{
				this.y--;
			}
				this.y += yspeed;

It works somewhat, but when I get to a damn hill, it bounces up and down real fast. I think the problem is the "gravity" is pulling it down too far, then it's being spat back out by the while loop. Any solutions? I'm pretty new to AS3, so I can't really think of one -_-

Ahh figured it out now. Adjust its position relative to player

x = -player.x+stage.stageWidth/2;
y = -player.y+stage.stageHeight/2;

This code would make the player always in the center of the screen, the math should be self-explanatory, but I can explain if needed.

This helps a lot, thanks! I think I understand the math...

One thing though- Any idea how you'd add lag? Like, when my character reaches top speed, the camera lags a bit. Perhaps setting some variables to mess with the math there that interact with the "speed" variable?

Let's say I'm making a platformer... like mario to give an example. How does one make the "camera" follow the player? And then, how would you go about adding lag?

I'm using AS3... not asking for a giant copypasta, but a general idea. Copypasta is fine too, but without an explanation of the code it's useless...

At 2/8/09 11:50 PM, baboop wrote: yea im working on a platformer and i dont want to move with the arrow keys how would i move with

WASD??

Instead of making it check the Arrow keys, make it check the keycode. e.g.

if (e.keyCode == 68)
{
blahblah
}

I know D is 68 off the top of my head...

since I don't use AS2 I can't help much...

But I -know- there's tons of tutorials in the portal that cover most of those things you brought up. But really, you can't just code a game. You have to learn the language a little first, then things will be so easy.

thanks guys, that helped me a lot!

Maybe I wasn't clear enough.

In code... in actionscript 3 to be specific. Not the drawing environment.

Are you using AS3?

Then put this in the frame :

yourbuttonsinstancenamehere.addEventList ener(MouseEvent.MOUSE_DOWN, functionName);

function functionName(event:MouseEvent):void
{
gotoAndStop(1);
}

I don't get why people still use AS2...

How does one do a horizontal flip in AS3? Thanks.

I have no clue why this is happening...

I have a listener for KEY_DOWN that fires this function :

public function keyDownHandler(e:KeyboardEvent)
{
if (e.keyCode == 90)
{
trace(e.keyCode);
}
}

For whatever reason, it doesn't work with 90 (which is Z), but it works with D (68). Anyone know why?

How do you change that? e.g., the constructor of the Document class... doesn't that always run no matter what?

Does the 'export in first frame' option have to do with this?

Sounds like its freezing because of a neverending loop... most likely one of those whiles. If I were you, I'd use an event listener that checks for the collision every frame as opposed to a while loop.

here the code on the enterFrmae:

while (_root.walljumpwall.hitTest (_x, _y, true)) {
walljump = true;
djump = false;
tjump = false;
}
if (_root.walljumpwall.hitTest (_x, _y, true) && !Key.isDown (Key.UP)) {
gotoAndStop (2)
_xscale -= scale;
}
while (_root.walljumpwall2.hitTest (_x, _y, true)) {

djump = false;
tjump = false;
}
if (_root.walljumpwall2.hitTest (_x, _y, true) && !Key.isDown (Key.UP)) {
gotoAndStop (2)
_xscale = scale;
}

heres the code for the clip ever load:

var walljump:Number = 10;
var walljump:Boolean = false;

it seems whenever i jump at the wall it freezes my flash. any help here?

Let's say I program a game using .as files... How would I add a few introductory frames before the scripts are loaded? Right now it just tries to load everything on frame 1.

thanks!

What would the non naive way be then? :\ I just can't think of anything besides putting the code in the "circle" class.

Perhaps using an array...?

so I 'm trying to make it when one object hits another one, something happens.

Is there anyway to make it check the object, and not the instance name? Like, some sort of wildcard would help.

For example :

I have Box. I create many circles in random places dynamically. If I assign code to the object box to detect the hitTest, what would it be? Assume I can't put the code in the circle class.
