1  Games Center / Featured Games / Re: Blocks That Matter on: 2012-06-06 22:05:16
yes of course Smiley

Seems nice. But i never was a fan of 3D isometric action games.

Slow RPGs are fine. But fast games like Sonic 3D (Mega-Drive) are not fun, especially on a PC keyboard.

In Bastion, i felt straight away I would forever be annoyed of moving in middle directions compared to Up/Down/Left/Right.

I need a gamepad.

but anyways I prefer dark and mysterious games. Limbo fits the bill perfectly. I feel the urge to play it. Bastion, I can't bother. Seems like the usual boring hack and slash. I prefer playing flat RPGs like Shining in the Darkness.

Limbo makes me think of Another World / Out of this World. For me Limbo repaid me the bundle's price.

Hehe I'm not as passionate about it but I agree with longino Grin

I agree with you and longino. I did some C# programming. Vusual Studio SUCKKKKKKKKKKKKKS. I HATEEEE IT. I WANT TO KILL. I feel like a claustrophobic idiot in a cave.

i bought the current bundle.

Limbo is really great

Kinda dead thread Sad

But yes, those numbers are real. The pay-what-you-wish is pretty successful, the Humble Bundle has been around for a while now. As you can see, this game isn't in the bundle anymore.

why not? Where can you get the bundle with Blocks that Matter?

Do you need an internet connection to play the bundle ? FYI I will never buy a game like Age of Empires online that will be unplayable when the editors decide to pull the plug the server.

OK: i got the info needed at
5  Games Center / Featured Games / Re: Blocks That Matter on: 2012-06-06 16:38:05
The games is also now part of the Humble Voxatron Bundle, pretty nice bargin IMO.

A quick comment on humblebundle?

Sounds awesome. Never heard of it. Sounds a nice business model. Transparency on the prices. WOW. Are those numbers for real? 400k sells?
6  Games Center / Featured Games / Re: Pixel Towers - Android / Desktop Game on: 2012-06-06 15:49:06

Downloaded. Extracted on my PC desktop. Run it. Played it!

Great game with nice music.

There is an annoying problem though. When you double click the mouse during play, the game ends and goes straight back the the menu. really sucks when in the heat of the game because of a mis double-click.

happens to me most of the time. and you lose your highscore screen.. Sad

I would also like a Up and Down scrolling of my tower during the highscore Smiley and why not an export to JPG Smiley
7  Game Development / Game Mechanics / Re: elliptic trigonometry problem on: 2011-06-25 19:01:06
hey thx for asking. I still haven't managed to do that one.

It is for drawing shapes of leaves. A simply ellipse does not look like a leaf.

So let's say I want a leaf with 10 pixels on the left, 15 pixels on the right (for a total of 25 pixels in width). Leaf is say 100 pixel in length/height.

I decided to model half a leaf as an ellipse cut by a vertical line.

This is what I do for drawing half a leaf

I know the top point of the leaf. topX,topY (can be modeled as point M in figure)
I know the bottom pointer of the leaf, botX,botY

In my case topX=botX. I will do rotations later if needed.

I know that the distance between a and a' in the above image is 10 pixels for the left part.

Once I know a and b of the ellipse, I draw the ellipse correctly offsetted and clipping on the area of half the leaf, it draws the left half of the leave.

It does not matter if there is an unknown. This unknown can be made a parameter for the leaf creation and put into the equation.

I just need this ellipse equation that goes through

(topX,topY) (topX, botY) (vertical line) and (topX + 10, MiddlePointer Between TopY and BotY). This last point is the (Distance(a,a') in the model)

that's for one part. the other part is similar except the other way around.

all I managed to do is draw half a real ellipse and not a truncated one. so maybe I don't model the problem correctly.

thx for your time.
8  Game Development / Game Mechanics / Re: elliptic trigonometry problem on: 2011-06-19 11:22:33
got another problem

consider again the figure above

this time

b' is known (V2)
a-a' is know (V1)

The trick is that a is not know, nor is a'! We only know the distance between them.

Find a and b Smiley

I'm not sure there is a single solution. I guess there will be a formula of b against a.

From the equation x2/a2 +  y2/b2 = 1

I have (a-V1)2/a2 + V22/b2=1

if k = (a-V1)2/a2

b = V2 / sqrt( 1-k )

So here I have formula of b against a but when I draw it on screen it doesn't work.

The idea is knowing M point and its opposite N, draw an elliptic Arc through those 2 points and point a. but center of ellipse is not know.
9  Game Development / Game Mechanics / Re: elliptic trigonometry problem on: 2011-06-18 17:03:38
i'm surprised there is no cosine in the formula.

but that's great.

thx man Smiley

for alpha it sure is easy once you know a' and b'.

10  Game Development / Game Mechanics / elliptic trigonometry problem on: 2011-06-17 16:41:08

please consider this figure

b is known
a is known
a' is known

find b' and alpha

I have been banging my head for one hour and can't find it. need to give it some rest.

knowing a', I need to find the point M's y coordinate.

I have been looking at this pdf but that was too much for me
11  Java Game APIs & Engines / Java 2D / Re: Palette drawing on: 2011-06-17 10:51:03
yea that's an idea.

caching the often used images brings some mixed advantages.

12  Game Development / Performance Tuning / which FP Math library do you use and recommend? on: 2011-06-16 13:42:59

I have found

Do you have any other?

I need to be 100% certain that two hosts compute the exact same value. using the ACOS function and COS function.

13  Java Game APIs & Engines / Java 2D / Palette drawing on: 2011-06-16 11:26:18

I have 100 MB of images that need to be kept in memory.

8 different colors (for up to 8 players) are used with 8 different RGB values (draw units).

Right now my options are

1) create a new image on the fly modifying the Player Color of the base image : CPU consuming

2) Create a copy for each Player Color 100 * 8 = 800 mb

I want to draw those images giving a palette parameter. Wouldn't that be faster?

Is that possible with Swing?

18  Discussions / General Discussions / Re: Is java still the way to go? on: 2011-04-16 13:35:54
Visual Studio is a piece is shit.

Features suck. It sometimes is very slow. I hate it when doing some C# and ASP.NET.

The problem with Netbeans is not Java. The problem is the bloated Swing UI. I don't know exactly what's the problem. But everynow and then your mouse pointer hicups. And for example, you cannot play with even simple menus without serious graphical lag.

Dual Screen using Eclipse makes coding fun. (anyone has a triple screen setup ?)
19  Discussions / General Discussions / Java console dev kit? on: 2011-04-01 22:09:40
Does any of you dream of a dev kit for programming games for a console in Java? Any idea if Oracle would be interested? Wink

I'm a 2D guy and never liked 3D except FPS.

I wish I could program games for my Megadrive in Java. Give me a J2ME Game Canvas with pad buttons bit flags, a sound interface and off you go making Mega Drive games clones. There is something completely unique playing with big black 6 buttons Sega pads on an old CRT TV.

If you played Alien Soldier written by Treasure, you know what I'm talking about. FYI there is a company in the UK, still making oldschool RPGs for the Mega Drive. But that's for in know Sega collectors.

Anyways, looking around for a java SDK kit on a console, i found none. But I found this.


You can upload your highscores.

Games for MSX, Arcade and Sega Master System.

Sound emulation of Yamaha sound chip! cool.  Cool

I advice you to check out After Burner 2 Arcade. Amazing 3D effects in 2D. Awesome fast gameplay! in Java emulation! Smiley

1-did you play 16 bits console? Sega or Nintendo?
2-did you play RTS games on the PC?
3-Do you think a 2D online RTS game is possible in Java?
4-How do you debug your code? breakpoints? or sysout or another logger?
5-Do you sleep when you are tired? Do you wake up on demand.
6-What's so bad about JavaSound? MIDI wierd instruments for sound effects?
7-In the Demo, nice effect when Big titan destroys your base. That was the first time I lost. this is the only mission that stroke a good difficulty balance.. I guess it is very difficult to create not too easy, and not too hard levels without being repetitive.
8-in the light of your experience, how do you see the anti piracy battle evolve in the future? Is it worth fighting it? Is the FarmVille model the future?

at first (back in 2001) NB fanatic.

then 2004-2011, Eclipse FTW.

Tried NB 6 but can't be bothered. Swing UI is too unresponsive. Loading a menu takes that annoying split second time.

Eclipse on Vista has good looking font with anti-aliasing.
25  Games Center / Featured Games / Re: Bug Bomb on: 2011-03-13 14:29:58

Very polished and I really like how the game keeps flowing even before you start or after you die!

Fun game. hard enough to be addictive.

1# Java failed on the desktop because Sun never bothered creating an application shop for java applications. You should have been able to launch "Java Control" and find a list of all java applications installed on your desktop and manage them from there. Some kind of  Java OS layer on the top of windows.

That is a very minor (if at all) factor IMO. Flash didn't (and doesn't) have an "application shop" and that didn't prevent it from becoming the de-facto standard for web games.

well, at the time it was not called "app shop". I remember when Java Web Start came along. That was brilliant. Why not having a favorite list of JNLPs? A tool to manage downloaded JNLPs? They did nothing else but provide the mechanism of Java Web Start. They didn't bother building the bells and whistles. They might have coined the word "app store" before Apple if they did some end user/desktop work at the time.
Back then I was thinking, build a bloody Java OS layer over Windows. They did not. too bad.

It is like the failed Savaje os/phone. Sun is a failure in end user experience. You can't win it all. Their core competence was server side.
27  Discussions / General Discussions / Re: Scrolls on: 2011-03-10 10:07:53
Cool stuff, looking forward to see how this plays.

It hasn't got the community networking that MineCraft has tho, unless they let players build their own cards and auction them or something.

Looks like they'll be going up against PoxNora (again written in Java) and now owned by Sony Online Entertainment.

Wow, that guy who made poxnora was on these forums too. Congrats to him getting bought out by sony. Pretty cool!

poxnora looks pretty cool. It is all Java?

i did not try because I don't want to use my facebook id and they don't support openid

I will just repeat

1# Java failed on the desktop because Sun never bothered creating an application shop for java applications. You should have been able to launch "Java Control" and find a list of all java applications installed on your desktop and manage them from there. Some kind of  Java OS layer on the top of windows.

2#J2SE is good because of backward compatiblity but it has grown thick and fat. Too many useless classes. Keep it for those who need it.

3#Sun should have taken the J2ME core classes Graphics, Canvas and bases classes like String and build a super lean super light framework. Scrap the LCDUI package. Scrap Vector. Keep backward compatiblity of bytecode.

4# on top of the lean base framework, create a Swing module and Game Interface module. Make it so you can load Base+GameInterface without loading Swing.

30  Discussions / General Discussions / Re: Mac App Store without Java on: 2010-10-28 20:24:34
you guys get it ?

Apple is asking for Oracle to do the JVM for OSx

Which is fair enough. Of course for mac laptop fan boys, it would be terrible if Oracle decides to ignore OS.x.

Some people think Oracle cannot do that.

I don't care. I never buy Apple locked stuff.
