1  Games Center / 4K Game Competition - 2011 / Re: Bike 4K on: 2011-03-02 23:33:20
What was the issue on osx. It ran very smoothly on my mac mini. Is it maybe the keyboard handling. I noticed that on some machices PC or mac when space is hit to jump whilst the right arrow key is down the right arrow key gets a key release event. Does any one have a solution to this. So for example I get right arrow down, space down, space up, right arrow up even though the right arrow key has not been released. The work around for now is to release and repress the arrow key but if this is the problem reported by Kevin it is very anoying.

Glad you liked the graphics. Yes the coins can be above the screen if the terrain is close to the top of the screen. You can watch the scrolling intro to see where they are located.

Just posted my game. You can play it at:
http://www.java4k.com/index.php?action=games&method=view&gid=344
Much thanks to the Java4k site organizers and the compile N shrink service. It was almost too easy to shrink and submit a game. I had many left over bytes this year.

Awesome. I found all 50 before you put the map in. I thought the search was the point of the game. Just a small nit pic the ferns are a side on view but the rest looks to be a top down view. However it still looks great. A contender for sure.
5  Games Center / 4K Game Competition - 2009 / Re: Q*Bert4K on: 2009-02-05 00:02:46
Just updated the game. Fixed the death on last square and added a bunch of new levels. Let me know if there are any issues. Also added faster balls and a green gremlin that turns the squares back to the original color. Also squares that must be hit twice. The format of a level is as follows:

1  
2  
3  
4  
5  
6  
7  
                       "      p      "+
                       "     * *     "+
                       "    * * *    "+
                       " l * * * * r "+
                       "  * + + * *  "+
                       " * * * * * * "+
                       "- - - - - - -",

a 13X7 grid
Where
p = player start square
* = normal square
- = snake spawn point
l,r = left and right flying disk
+ = double hit square
space = empty square

If any one wants to send me an interesting level I still have room to include it.

I just posted a version with yield replaced by sleep. See if this fixes your key board issue.
7  Games Center / 4K Game Competition - 2009 / Re: Bio Wars 4K on: 2009-02-02 19:25:25
I tested on my work computer which is very slow and has a poor graphics card. It ran at 20 frames/sec but still played very smoothly. So I now think it is something to do with either the threading or how keyboard events are delivered on your system. You are getting 50 frames/sec which is a pretty good rate. The only thing left that I could try would be to replace the yield call with a sleep call. Maybe that would force the event thread to kick in and register the key board presses.
8  Games Center / 4K Game Competition - 2009 / Re: Bio Wars 4K on: 2009-02-01 19:45:02
Ok I just uploaded a version with a frame rate counter in the upper right corner. I limit the frame rate to 60 so let me know what frame rate you are getting on your system.
9  Games Center / 4K Game Competition - 2009 / Re: Bio Wars 4K on: 2009-02-01 19:27:23
The last fix does a yield every frame draw so if you are only getting key events every 1/2 sec either your frame rate is only 2 frames a second or for some reason your system is reporting key events at a very slow rate. I will try and put a frame rate counter in so you can see what frame rate you are getting.
10  Games Center / 4K Game Competition - 2009 / Re: Q*Bert4K on: 2009-02-01 16:21:20
I found the problem. I had a while loop to maintain the frame rate but on slow systems there was never any free time left over so the while loop was never entered. The result was yield was never called so the event thread was starved hence the key press was missed. I changed to a do while so yield will be called on every render loop.

I saw the bug on the die on the last square too. I will look into it as soon as I can until then don't die on the last sqaure  Smiley.

Try now and it should work on your system.

Thanks for the feed back.
12  Games Center / 4K Game Competition - 2009 / Re: Bio Wars 4K on: 2009-01-30 21:13:11
Can you describe the key behaviour. Does the player move too fast or too slow.
13  Games Center / 4K Game Competition - 2009 / Re: Q*Bert4K on: 2009-01-30 21:03:44
I replaced the jar with a version that uses nanoTime instead of currentTimeMillis. So hopefully this will maintain a better frame and key checking rate. Was it running slowly on your machine.
I am just overiding the processKeyEvent() method to store the key press and then checking for the key in the game loop. So if you are missing events the only thing i can think of is that the game loop is running too slow. If it is still a problem I will look and decoupling the logic loop from the draw loop.

Not sure what the issue with the gray screen is, any exception. I also now get and dispose of the graphics context each frame so this may fix the gray screen issue. Refresh and let me know if it helps.

16  Game Development / Newbie & Debugging Questions / Re: constant FPS on: 2007-09-25 14:52:44
You could try moving the System.out.println(startTime) to after the endTime = statement, as the way you have it coded you are measuring the print time as well as the sleep time.

17  Games Center / 4K Game Competition - 2007 / Re: 4K 2007 Results! on: 2007-07-30 14:09:31
I am very pleased with how my game did, and I certainly enjoyed playing all the games. I did not know about any prizes. I would be happy to try out Tribal Trouble. Does fourth quallify me for any of the prizes.

Woops!  Embarrassed Please ignore my previous comments about Vball4k. I did not realize there was another vball game. Sorry for the confusion. Looking foward to the review of mine. But I guess I will need to wait a bit as it looks like you are reviewing in the order on the javaunlimited site and mine is very close to the end.

Keep up the good work.
19  Games Center / 4K Game Competition - 2007 / Re: Inofficial Feedback on: 2007-04-04 21:16:48
Thanks for offering feed back on the games. You are to be commended for stepping in and making a positive contribution instead of just complaining and flaming as is happening in other threads. I enjoyed reading the comments on my VBall4k entry. Just thought I would point out that the direction of the ball can be controlled by moving the target spot before hitting the ball.  This is controlled with the mouse not the left/right keys. In this way you can pass the ball and achieve a set up for a spike. Not quite sure how you were able to play the game if you were not using this feature. The speed of the ball is also controlled by the timeing of the hit. The higher the ball is hit the harder it will go. Thus let it fall low for a soft set or jump and hit it high for a hard spike.

Thanks once again.
20  Game Development / Newbie & Debugging Questions / Directory listing of directory in a jar on: 2007-04-02 20:51:50

Is it possible to use the String[] File.list() method to get the files in a directory once the directory is put into a jar file. I have some code that uses this to get a list of resources (for example a list of image files). I would like to convert the application so it is web startable and put the resource in the jar file. Can I do this if I use the File(URI) constructor or should I do it manually with the ZipFile class?
21  Games Center / 4K Game Competition - 2007 / Re: aichess on: 2007-01-06 15:33:28
Great job. One suggestion the black  pieces on the black squares are hard to see on my monitor, maybe red on black or black on red would be eaiser to see.

22  Games Center / 4K Game Competition - 2007 / Re: Starship Invaders (4k) on: 2006-12-18 22:57:54
Nice game. I noticed that the phaser disappears after the first game but you can still kill the warbirds. For some reason the phaser line is not drawn. Your ship also jitters like crazy if you try to leave Federation space.

What about instead of radar. The eyes looked in the direction of the next baby.
24  Games Center / 4K Game Competition - 2007 / Re: 4K V-Ball on: 2006-12-07 00:20:37
I was waiting for feed back to see how hard it was. I thought it was too easy. Of course once you play it over and over whilst developing I guess it does tend to get easy. I was even thinking of increasing the opponent speed on the fly to keep the game even. I could lower the speed if the opponent gets too far ahead, they take it easy. Or increase the speed if the opponent falls behind, they fight back.

Ok here are some hints to beat the game. 

You need to set up the ball for a spike like in the real game. To do this when receiving the ball place the yellow target between the two front players. I usually place it between the two front right players. The closer player will go for the ball. do not move the target just pass the ball straight up. This will result in a high set. The other player will then move in for the ball. Now move the target to an open spot on the oponents court. I usually pick the corner just inside the 10 foot line.  Click to jump and either click again at the top of the jump or just keep the mouse down This should result in a nice hard spike and with any luck should win the point. If the opponent manages to return the spike just try again the ball needs to get to the spot before the opponent can run it down. Once you get the right technique you should be unbeatable.

One other hint is to watch the blue shadow of the ball and click the mouse when the shadow is just in front of the player. You will never hit the ball if the shadow gets past you.

The sound takes 266 compressed bytes. This is I built and compressed with all the sound code removed the difference is 266 bytes.
26  Games Center / 4K Game Competition - 2007 / Re: 4K V-Ball on: 2006-12-06 06:16:08
I updated the target movement so it is now closer to the cursor. It is still not 100% on but better than before. I did not have room to hide the cursor or do a full inverse function to get it eactly right. See if you think it's any better.
27  Games Center / 4K Game Competition - 2007 / Re: Goop on: 2006-12-05 03:18:16
Great game as usual.

It would be good if there was some indication as to which direction the next babie is. I found myself lost a few times.

Edit: Yay I scored a point. I think I figured out how the yellow dot works. You have some vertical rectangle as the input area and you just ran out of space to translate that to the angled field I guess?

The Yellow dot is the target that the ball will travel towards when it is hit. It slides along the floor of the court. The court is in 3D but the mouse is in 2D. So the translation means the mouse and target can not stay in sync. If you move the mouse left and right the target moves left and right on the court. If you move the mouse up and down the target moves up and down the court.

If someone has any suggestions on how this could be improved I would love to hear.

Thanks for the positive comments.

PS. I do not know if you noticed bu the game has some sound effects as well.

Thanks to all the judges your comments were great. The entries were outstanding this year.

ChrisM, thanks for the comment on my Ladybug game.  I was ok with the position that it placed in the competition, tied for 10th in score but 11th in postion. Guess I will need to make games that sort higher in the alphabet. Smiley

But I was surprized at what games beat it, and at what games it beat. It looks like there is no consideration as to how much was squezeed into a game. Some very simple games made it to the top, while some very complex games were way down. Looks like you need a game that has very simple controls and that gives a game over in about 30 secs. This way it becomes what the judges call "addictive", That is, I surely can do better than 30 secs.

Of course none of these comments apply to Miner a great example of what a 4K game should be. I certainly thought it deserved to win.

Congrats to all the entries. The best J4K  yet. Can't wait till next year.
