Walk cycles for sprites? That's even simpler than easy!

Go to Newgrounds Flash Tutorials They got some really good spriting tutorials, check them out.

I'll try speeding up the pace of the game.

The graphics will certainly be improved.

And I want the enemies to randomly spawn from every side just outside the stage.

Thanks for the review... sort of though.

Do it like this

var level1:Boolean = true;
var level2:Boolean = false;
var level3:Boolean = false;
...

if (char.hitTestObject(level1Goal)) {
level2 = true;
gotoAndStop("LevelSelect");
}

if(level2) {
level2_button.gotoAndStop("Unlocked")
}

I think that should work.

Alright so I'm working on this game with a copter, the engine's almost ready but It still needs a few adjustments. Here's the game prototype in Super-Pre-Alpha-Beta-Omega-Testing-Phase . A, S, D to shoot and Arrow Keys to fly.

The game is in AS3 and I have lots of external classes, the main timeline doesn't have that much code.

What I need is to make enemies spawn from all sides behind the stage, I haven't found any comfortable way to achieve that.

Also can you tell me what you like about the game engine so far, what could be improved (how?) and what you don't like.

All help and criticism will be very much appreciated, thanks!

Asshole.

As to the problem, can I see your .fla or .swf I'm still not sure what's going on in your flash.

Well, I need more info, is it AS2 or AS3 and what have you got so far.

Just use a vCam and point the vCams position to the characters position, like this.

vCam.x = char.x /* Assuming that the vCam has the instance "vCam" and the character has the instance "char" */
vCam.y = char.y

Search Google for flash vCam!

Add (assuming your char's instance is char)

char.rotation = // 0 for UP, 90 for LEFT, 180 for DOWN, 270 for LEFT

Simple as that.

I forgot, Add it to your Movement functions, under the named directions.

Can you post the .fla, I'm not so sure I get the problem.

Also you may want to improve the code a bit, make the player face where he's heading.

Add this to every KEY_DOWN function

PlayerMc.rotation = (0 = UP, 90 = RIGHT, 180 = DOWN, 270 = LEFT)

I'm in a helping mood in case you're wondering :D

By the way, I just found out that you still have a little bug.

Change:

PlayerMc.x = -MoveSpeed;

to

PlayerMc.x -= MoveSpeed;

Have Fun!

I found your problem.

PlayerMc.addEventListener(KeyboardEvent.KEY_DOWN, Down);
PlayerMc.addEventListener(KeyboardEvent.KEY_UP, Up);

That should be

stage.addEventListener(KeyboardEvent.KEY_DOWN, Down);
stage.addEventListener(KeyboardEvent.KEY_UP, Up);

I found this while testing.

Scene 1, Layer 'Layer 3', Frame 1, Line 12 Warning: 1106: Empty statement found where block of code expected. Did you type ';' accidentally?

It still won't work though. I'm looking into it, shouldn't take long.

this post is completely unrelated, but i had to lol when you said that. yoiu've got code there that i can't even start to decipher, don't be so modest :P

Thing is I'm using another person's code, I think it was Grant Skinner's PixelPerfectCollisionDetection ported to AS3. The first code is me though :)

You got any idea how to fix that, I'm not that big on AS :)

Maybe by the logo? That could show me what you can do. As you saw in the description, it have to be 450x300 pixels and must look like a Phoenix Wright title.

The complete name of the game is "Phoenix Wright : Tails Abuse". Thanks for helping me out!

Alright, time to get creative! By the way it would be much easier to talk over real-time chat, is it MSN, ICQ or whatever, if that's okey with you.

Hey, I like to draw! I'd really like to try and make the art for this one, got any specifications where I should start?

This little problem blows, at least my mind. First of all here's my code.

import com.asgamer.helicopter.PixelPerfectCollisionDetection
import com.asgamer.helicopter.Helicopter
import flash.events.Event;

var heli:Helicopter = new Helicopter(stage);
			addChild(heli);

addEventListener(Event.ENTER_FRAME, frame)
			
		function frame (e:Event) {
	
	vCam.y = heli.y
	
	if ( PixelPerfectCollisionDetection.isColliding( heli, walls, this, true, 1))
	 {
		debug_txt.text = "Hit!"
	}
	else
	{debug_txt.text = "Not Hit!" }
}

And here's my prototype http://megaswf.com/view/1c312c72844d78df e72f6e61e757ed0e.html

The problem is that technically it should display "Hit!" whenever it touches any of the grey space, for some reason it won't work for the bigger block of grey in the bottom.

I'm using this PixelPerfect Detection.

package com.asgamer.helicopter

Thanks for the input though, man.

Glad you figured it out!

Have you tried re-animating, completely from scratch? Or you could try breaking or tracing the bitmap (Break: Mac OS - Cmd + B, Win - Ctrl + B Trace - Modify > Bitmap > Trace Bitmap)

First of all how did you animate it, it seems they are the dots of the pen tool.

If Flash throws errors at you when you export, then you made a mistake with the code.

Yes, Flash does have a quiz system, but I always like to make my own as it's not hard at all to create one. Miking your own also gives you more space for creativity. To my knowledge Quizes consist of only buttons so the coding shouldn't be that difficult, I recommend AS3.

Alright, I noticed you copied the platformer code from kirupa.org, not good. The main aim of tutorials is to help you learn, not to give you scripts to copy. I imagine you ripped the graphics from somewhere too. Anyway first step would be to learn AS3 coding, the world is moving to AS3 aswell. To get started google "as3 basics" or something like that. Then start off with easier games, like quizes and move on to more complex games like platformers.

Here's a quick example of simple AS3.

button.addEventListener(MouseEvent.CLICK, clicked)

function clicked (e:Event)
{
trace("Clicked!")
}

Now when you click the movie clip "button" the output panel should display "Clicked!"
It's not really that hard, I find it even more logical than AS2.
If you truly want to learn, then by the end of this day you can write something similiar in AS3. Make your mom proud!

Thanks, it really helped understand the concept of Key Events. Thanks again!
