1  Games Center / 4K Game Competition - 2008 / 4k - Balance on: 2008-03-01 20:07:42
Hello all,

This is my submission for this year. I had some more ideas, but not enough time, Smiley

You have to control the platform inclination to move the ball to the red square. Use the mouse movement to control it.. These are the controls:

- 1 - 7: Choose map.
- Mouse movement: Choose platform inclination.
- Left mouse button: start / restart.
- Right mouse button: change current map mode or restart it if it is running.

Suggestions, ideas ande feedback always welcome.

And a request for the admins. I didn't realize the related preview image was a local path and I set a web link to the image. Now, I can't chage it. The image is Could you help me to change it? Thanks

Hi all:

My Google gadget version for this game:

If you have any of your games in a gadget, share it, and I'll add it to my startup Google page.

3  Games Center / 4K Game Competition - 2007 / Where are my downloads on: 2007-04-03 22:47:36
Last time checked the web, my games had the following figures:

Now, they have ~830 and ~380 respectively.

Only for your information, data have been manually modified. Any reason? Have downloads in your games been reduced?

It works fine now.
Thank you very much.


Sorry for not testing the link before. I didn't know it was going to change.

A few details:

JAR file:
Last modification date: 02/18/2007
It is aute-executable, and it works by webstart

Thank you
6  Games Center / 4K Game Competition - 2007 / Re: Oh Mummy!, a classic game on: 2007-03-25 22:58:25
It is self-contained. It worked, but it doesn't now.
Just try the link:

On February 18th, it worked perfectly, as a post in this thread shows. I haven't change anything in the JAR file since then. So, please, change the link to the real location or update your local copy of the JAR file to this last version, previous to the ending of the contest.

Thank you.

Why my webstart link is broken?

The real link should be: (it works)

I've been trying to edit the submission, but the system doesn't allow me.

Please, could the administrator solve this problem?
Thank you.

PS: what is Gj? sorry, I'm spanish and I don't understand that sentence ;P
Gj - Great job?
I'm Spanish too, I'm just guessing.

(new ObjectInputStream(O.class.getResourceAsStream("o"))).read(bytesRead);

Perfect. Thanks a lot. Grin
12  Games Center / 4K Game Competition - 2007 / Re: Oh Mummy!, a classic game on: 2007-02-18 19:25:16

Thank you for your help. This code returned me the same exception. It finally worked with:

(new ObjectInputStream(URLClassLoader.newInstance(new URL[]{new URL("")}).getResourceAsStream("o"))).read(bytesRead);

I couldn't use it due to the size, 100+ bytes more, and also I didn't like to use an absolute URL reference,  Sad. So, I'm sorry for not using a jnlp file.

Now, I have improved the game:
- Improved the frame rate handler.
- Speed has been increased. Each 3 levels, it is faster and faster, until level 9; faster was uncontrollable.
- Now, the game can be continued. You can continue playing in the same level, but the score will be reset, Tongue

As soon as I can comment a bit mre the code, I'll share it.

Enjoy the game, Smiley

Hi all:

I increased the speed, but I have a problem with the jnlp file.

I have a resource called 'o' with the sprites. I try to load it in the following way:
byte[] bytesRead = new byte[8*144*3]; // 16*144*3 / 2
(new ObjectInputStream(ClassLoader.getSystemResourceAsStream("o"))).read(bytesRead);

As you can see if you have played the game, it works perfectly downloading the jar file, but launching from the jnlp file I get a null exception because it can't find the resource. This is my jnlp file:

<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0" codebase="">
    <title>Oh Mummy!</title>
    <vendor>Luis Javier Lopez Arredondo</vendor>
    <description>Run away from the mummies.</description>
    <description kind="short">Oh Mummy!</description>
    <icon href=""/>
   <j2se href="" version="1.5+"/>
   <jar href="mmod.jar" downloaded="eager"/>
<application-desc main-class="O"/>

 Huh Do I have to include anything in the jnlp file to make the resource recheable?
 Huh Do I load wrongly the resource?

Thank you.

Anyway, during my googling I came across the 4K competition. Of course! There's bound to be a tight, efficient way of doing things in an application in there somewhere I thought - and I found the answers I needed in the Billiard4K game. So thanks to Luis Javier López Arredondo for saving my sanity!

Thanks to you. I didn't know my code could help you, Tongue

16  Games Center / 4K Game Competition - 2007 / Re: Oh Mummy!, a classic game on: 2007-02-13 18:35:51
Yes, there were trap blocks.

My initial idea was to implement it, but I had tu reduce a lot of features, Sad, like looking for the original objects instead of the green blocks, Tongue.

I also wanted to include the original song, but was completely impossible,  Sad
I found it here. Sure it brings you some memories, Smiley
17  Games Center / 4K Game Competition - 2007 / Re: Oh Mummy!, a classic game on: 2007-02-13 16:53:49
Thank you for your opinion. The pace is increased in each level. I can adjust it.

Does anybody know a host that accepts jnlp?

Hi all:

This is my second entry for the contest, after 4k - Billard.


I think that this was the first game I played in my old Amstrad. It was loaded from a cassette and it lasted a lot of time.

The concept is easy. You control the man with the direction arrows. You have to find the two green blocks to pass to the next level. When you had found the two green blocks, come back to home to pass to the next level.To know the color of the block, you have to walk all around it. Be careful with the mummies, each level has more of them and they are cleverer and cleverer.

It has been a very hard job. I'm collecting all the useful tricks I have done to reduce the final size of the jar, such as my own format for images, three nested loops in a single one,....

The game is in "Beta" version because I'm waiting for comments about it, the mummy intelligence level, suggestions... All opinions are welcome.

I hope you have fun with this 4k version of the game, as I did playing it and programming it.

It sounds interesting.

Please, give more details, requirements, awards, publications.... It's for March, so it can be tough.

I'm just updating my CV. By the moment, my home page is
4k - Billard is my first entry at J4K 2007 Contest.
