I can confirm that it was down for that period as i was going to see how nicely a j4k game will play on a eee pc netbook but couldnt

looking like a solid start

do those wall textures have bump maps or is it just a trick of the texture? either way well done.

Well applying pack200 would give a significant saving. You are correct, I think it was only in the 2010 competition that pack 200 was allowed. The 4kjo tool was before that rule was relaxed. I would suggest running pack 200 over the output jar p. however to achieve better gzip compression you will need to extract the gzip stream and use stronger gzip compressor. I think rivers tool when it existed used kip

done. the activation email was flagged as spam

I have a samsung gt-I8150T: FPS ~55 and and ~900+-50 sprites

lets try this then: http://www.divshare.com/download/24005551-d53

<sigh> ok, i cant access google docs from work so it will have to wait until i get home.

found it

I am sure some of my old posts will have more info about how to use it...

I probably have the 4kjo tool at home somewhere, but it was designed for Java 5 and 6... i dont know how compatible it will be for java 7

It seems that I am a hacker! never knew i was so 733t



I came back to work after a long weekend and refreshed the "Show unread posts since last visit" page.

Is this expected behavior? I have not had this occur before... It gave me a chuckle so I am happy for that 

Thanks for all your efforts judges! it took me hours to play each entry and I was not being as diligent as you guys!

I should have seen that! i blame my head cold...

That seems about right, the contest is really only known by members of this forum.

good job for every participant! i did start a game but real-life^tm got in my way.

It is interesting to see what the community's collective taste is. Can we have an idea of how many voted?

well i would suggest the opposite, feedback should be anonymous. What good can come from identifying the owners? the feedback is the same if done anonymously.At least it would protect the feed back owner from being "abused" by others, not necessarily the entry's author but other zealous individuals.

well the easiest way would be to use the standard Random class:



But if you do not want to use the standard Random Class then you can use a Multiply With Carry PRNG... http://en.wikipedia.org/wiki/Multiply-with-carry It even has some C code that you can just port to Java.

whats ChrisM up to these days? perhaps he would like to moonlight as a judge for old times sake?

That is fine, i am sure the authors would appreciate any and all feed back... i know i did when I had participated in the past. I was a little bit worried that my multi-hour effort of playing each entry and giving feedback would have been wasted for those which did not get a points ( I ran out of points )

Any reason that we cant give feed back on any submission? or is my understanding not correct? I gave a few entries 0 score... but that can only be achieved by leaving the score field blank... so how do you determine between a 0 score and a non-score?

I did leave feed back for all entries as i tested all entries.

Yikes has it been that long? it started in 2001 by then Sun employee Chris Melissinos

very impressive and smooth!

You gotta love the effects that noise can give cheaply!

Probably a silly suggestion, especially for a java 4k game, but have you tried promoting the priority of java process running your game? Perhap your OS is being a little to sparing to the process?

Can you give an example of an "older" system that presents the issues? I have started 10 parallel instances and there was no slower frame rates.... but that said, if this is for java 4k then you should really only care about making sure that it will work well with JRE7 and hardware that most people would have... i guess one would look at Steam's statistics for that info.

I think BestUserName is just trying to provide critical opinions. These are the best kind of responses as it allows you to better your game!

just to be sure have you actually done a per pixel comparison to confirm no difference between the two images?

I have taken another approach for minimising the byte count for storing and reading sprites... I have converted my PNG Sprite sheet into an "Uncompressed" PNG using deflate mode 0, adding it as a resource in the JAR , then using ImageIO to read it in.

The tool can be found here: http://pastebin.java-gaming.org/19df7886132

I converted your example 4K applet to use this uncompressed PNG: http://pastebin.java-gaming.org/9df78916237 and after jshrink and pack200 it saved a further 8 bytes over your method (but that is noise level so I am not sure that it will win in most/ all circumstances)

I used PNGGauntlet to optimise the PNG before using my tool.

Well, I use java2d because I am just a hobbiest  that nowerdays only really has time for java4k games.... so java2d meets my needs perfectly.


Sounds like me exactly. I actually do not have some grandiose (or not so grandiose) vision/plan for any games I attempt to make... and instead I learn concepts, techniques that I find interesting and if it progresses enough into a game then fantastic, otherwise i drop the game. You might call that a lack of commitment or determination... but why should I toil to complete a game that I do not have fun making?? To me the game aspect is a by-product of learning and implementing something I find interesting.

And is it any better to have a noob that has issues with another library such as slick or libgdx and posts a question here but gets no answer or wrong answers because the members here are not familiar with these libraries?

I believe all submissions are human vetted so there may be a delay

Like most methods in java, indexes are zero based, so I would imagine you would want to use
      raster.setPixels(0,0,width-1,height-1,endPixels);

well a simple but probably horribly inefficient way is to have an Area for each rectangle and then perform an Area.intersect(other area) see http://docs.oracle.com/javase/6/docs/api/java/awt/geom/Area.html

Looks like you are using the y component twice instead of the x component in your setrot method call
