I made it through and liked it. Very original concept! Push it forward.
The model is a bit dirty though. I has two separate modes - fast paced, when you need to run and jump and slow paced when you use the ability to put your weight on one leg. I felt that they somewhat contradict each other.
2  Discussions / General Discussions / Does really game development on Java suck? Why are we still here? on: 2012-03-18 18:39:40
Sorry guys. I don't want to offend anybody.

But it seems that right now we are weaker than other engines Cry
I've made a VERY thorough study. I visited all the sites (800+ of them) that are mentioned here on JGo by users. Half of them dead. Only some tiny amount makes me really interested. I've looked through the showcase (though most games I have seen on sites). I've seen the featured section. So I would say I was pretty much aware about 90% of everything in games written in java. (The only thing I haven't already done is looking for ALL Java4k entries and all Ludum Dare entries (I did for the best)).
ON THE CONTRARY: I've looked just through one single IGF 2012 entries. 550 games is not much. BUT. A considerable amount is REALLY AWESOME. 50-100 were very interesting, technically perfect, visually brilliant with a breath-taking atmosphere. People write games on Flash, Unity, Game Maker, Source, Unreal etc engines. They do it on C++ and C#. They do it for XBOX and Ipad. AND ONLY SELDOM they do it on Java. I have recognised very little amount of Java games on IGF (if any).

So, returning to the original question. Does really game development on Java suck? Why are we still here?
3  Game Development / Newbie & Debugging Questions / Re: How can input url pictures into post? [SOLVED] on: 2012-03-11 16:47:27
-ImageShack worked for me.
-I did it on Google but it didn't work.
-How can find the url to some dropbox file?
4  Game Development / Newbie & Debugging Questions / How can input url pictures into post? [SOLVED] on: 2012-03-10 17:25:44
I had a post and I had pictures.
I downloaded them on Google docs. Made them public on the web. If I paste an Url into post it doesn't work.
5  Discussions / General Discussions / Re: Go on, ask me anything. on: 2012-03-10 17:11:54
I would like to learn numbers)
Can I draw, say, 100000 sprites per frame?
Can I have, say, 10 000 000 million objects? What is the number, when you should forget about making it objects and try another approach.
As I understand OO is more for convinience and reusabilty.

Just to give the scent of my question. Let's have a tiled map. Every cell can have an object in it. If I follow strcitly OO, I make Cell.class, Entity.class. They communicate, Every cell knows what Entity it contains. But another thing I can think of is an array of cells and every cell object has a parameter, which tells us, which type of entity this cell contains. The second variant is more difficult to maintain, because I'll have to put all communication between entities into Cell.class which will become big.

In other words I would like to know the expenses and benefits on having an object instead of a field. How much additional memory (for an ampty object) it uses. How times of read/write accesses of an object and of a field vary.
6  Discussions / General Discussions / Re: Go on, ask me anything. on: 2012-03-10 10:55:04
I have a question.

-How many sprites can I update per frame? (for a desktop, say)
-I' a novice in OO programming. Is it really normal to have a separate object for each cell and every entity in the world? Or maybe I should just make separate arrays (Every array repersents some property of the object)
-What to do if I'm supposed to have many thousands of dynamic objects all the time on the screen and many more in the unseen world?

Fixed! Is it working now. If try it InPrivate it works so I believe you can also.
Finally fixed now using ImageShack!

Sorry for that. Why it can be so? Everything works for me.
I have downloaded pictures to Google docs and then copied URLs to them. They seem to have jpg format.

Hello All!
This post is based on the previous one where we have collected some data about how old game developers are, how many years are they programming and what accomplishments do they have. I strongly advice you to follow that link and add in some information about yourself. The more we now, the precizer statistics we have!

I have taken four numerical values: age, time with java (java years in charts), number of games made, number of good ideas for games.
Here are basic histogramms for all four values.

The facts I see:
-We are decaying with age (no wonder Stare)
-There are a large group of people (about 30%) who have an almost infinite pile of ideas
-Kev Glass and fruitmaze spoil the smooth curves because of their overproductivity  Wink (I had to cut them out on some graphics for not having a large scale.)
-With java years nothing is clear so far. Distribution is quite uniform.

And here are some correllations between main parameters.

-The first picture shows us that a very nice trend. People usually start programming on Java at the age between 10 and 20. The derivative of the trend is less than one, that means that new generations start with Java earlier. Who knows? We may see 5 year children in this chart soon.
-Other graphics are not so informative. It seems that my poll doesn't consider the very time spent on Game development. Here we come to lots of problems. Should we consider only professional and\or commercial games? Being with Java doesn't mean that people were developing games on java. I would like
-As there's not so much correlation between made games and the age I can state that the idea that one man (not the huge commercial company) can make a notwothy game has been widely spread not so long ago.

This one is just for beauty. It represents the dependence of made games from age and time with java.

Comments, Ideas?
Don't forget to write about yourself. Let's hit the hundred!
11  Game Development / Newbie & Debugging Questions / Re: How to work with a big world? EXTENSIVE QUESTIONS on: 2012-03-08 18:13:37
Could you advice culling and zoning tutorials.

Don't think I'm lazy. I tried to Google it. Mostly I found 3D connected topics.

My question is not so about chunks and Minecraft. But about OO programming. Don't millions of objects slow up the project? Is it better than having an array or List?
12  Game Development / Newbie & Debugging Questions / How to work with a big world? EXTENSIVE QUESTIONS on: 2012-03-06 20:49:06
I'm using LIBgdx. My game seems to be pretty intensive in the future. Actually I'm interested how to not overload my system?
1. I'm wondering how many sprites can be drawn simultaneously on the screen? (For a normal computer. I'm having about 15000 right now)
-Should I care about cheking whether I see a sprite on the screen?
2. How many objects should I have in my game?
-Imagine I have a tiled map.
             -Can I have a separate object for every tile? (Now I'm making a list of objects. I have about 15000, but need more for bigger world)
             -Or should I better have some arrays, where every array stands for a certain property of my object?

For Example, let's take Minecraft. There's a huge world. Millions of blocks. The world lives all the time around you. Especially when there's a lot of players.
-How does he draw them?
-How does he update the world?
-How can I make the chunk System?

P.S. Can Eclipse check how much that or that action takes? I understand I can put System.nanoTime(); but in NetBeans there's a special tool for it.

Don't you mind putting it everything into one table?

And Great Thanks for Support!

The problem was that my resourses lied in the root folder by default.
I should have placed them into the res folder as in my project!
15  Game Development / Newbie & Debugging Questions / Re: Problems with executables on: 2012-02-29 19:03:57
I read the Java tutorial and tried slicer it didn't work.
Slicer just makes something unexecutable (corrupt jar).
In tutorial it is written that you need to define Main-Class: Mymainclass
My main class is DesktopStarter
There's Some Rsrc-Main-Class in the default export manifest though.
If I try to make Main-Class: com.abstractgames.DesktopStarter it says it doesn't see it.
In my jar I have
-resources(pics etc)
-som folder containing eclipse classes
-Manifest folder

Here what I have in Manifest file
Manifest-Version: 1.0
Rsrc-Class-Path: ./ gdx-natives.jar gdx.jar gdx-sources.jar gdx-backen
d-lwjgl.jar gdx-backend-lwjgl-natives.jar
Class-Path: .
Rsrc-Main-Class: com.abstractgames.DesktopStarter
Main-Class: org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader

Hello All!
We live in the wave of Indie Game Development.
I want to learn more about our community. Here we have already collected a huge table(>= 35)!

Now we have come to some critical point where we can try to understand the realtions and behaviour between developers and games Wink
Comments for that analysis you can find here:
Here I've put some basics statistics, that can be curious.

Just some comments.
Try not to overemphasize ideas count. By ideas I understand a game conception you would have definitely brought to life if you had more time.
It seems that we should somehow divide big nice finished game projects from smaller and totally novice ones.

My name is Max and I'm interested in game development for two months already  Undecided. It messes up with my scientific career, but I just can't help thinking about the games.

17  Game Development / Newbie & Debugging Questions / [SOLVED] Problems with executables on: 2012-02-29 17:28:47
Hello once again!
I'm working in Eclipse with LibGDX.
I can't transform my Game into an Executable jar. Actually it does exports the jar. But I have a black screen and it quickly goes away. All three export options do not work (Packing libraries, attaching libraries and so on.) I don't have any errors or warnings during Export.
Googling hints that I might have problems with META-INF. But playing with it resulted in nothing so far.

-What should I do?
-Can you also suggest some infromation on applets.

Thanks in advance.

19  Game Development / Networking & Multiplayer / Re: Starting point for multiplayer development needed! on: 2012-02-29 15:34:57
Something like this.
I want to learn common methods for network programming. What language, packages are used? Where can I find the introduction, manuals and so on to finally implement my knowledge into multiplayer game?
20  Game Development / Networking & Multiplayer / Starting point for multiplayer development needed! on: 2012-02-29 14:34:16
Can Someone suggest me how can I introduce multiplayer in my game. Somehow I can't find anything to start with.
I NEED SOME NICE OVERVIEW with routes to follow.
Does LibGDX have anything to do with it?

Thank you in advance!
