Play My java Game - Debug

Hi there, you can download my game at :
http://www.hypercreative.co.nz/Space%20Walker.zip
I am having problems with it, for some reason, if the game doesnt play sound, the animation becomes waaay slower.
And also, I have tried to add more asteriods in to make the game more challenging but the animation lags aswell.
Also, the game speed is variable, everytime you run it goes at a different speed
wtf!

Mate no one here wants to donwload your game... if you have a problem with coding we can help you.

Using Firefox to play yahoo! games.........

I am trying to play some games that Yahoo! has to offer. When I click on a game to play a window pops open and says, "Wait 3 minutes for applet to load... Click here if applet fails to load." So I wait 3 minutes and nothing loads and when I click on the link nothing happens.
Does anyone else have these problems? Probably not many of you play Yahoo! games, but maybe you know something about "applets" and what I need to have installed on my computer to load one.
Thanks in advance for any help.

The games on the website are typically Java applets or quick Flash games, but there are others which require a download. Many of the games that require a download contain TryMedia Adware (According to McAfee SiteAdvisor).

I wonder if you have to sign up to play?
Do you have a particular game this happens with?

The ever so savvy "creating a java game" post

Hey, I'm creating a java game, and I did research, and found that this question has been asked many, many times. But my question unfortunately did not match up with any of these posts :( So here goes...
Im creating a java game, which will run as....kind of a mix between a 2d game, and 3d game (no i am not insane). I dont want the original zelda look, and i dont want the first person shooter look, I want my character to be viewed from an angle, like tibia - if anyone has ever played that. And I also want to leave open the door to changing the view within the game. I figured I can just get my graphics friends to draw things in 3-d, (draw a house [draw the 4 sides and the roof]), and then somehow skew these images to accomodate for a different view.
I am more than willing to code some kind of graphics engine if what I need is not available, I have looked at a couple and found no such luck.
So what is the most efficient way to create this game? By just sortof getting all the graphics to be from a certain percpective, and then somehow modifying them with java.....
or by using some kind of graphics engine that allows me to change views? If so any recomendations?
Thanks a lot - wow this was long, oh yea a couple Dukes for this too thanks again

you don't need to do any skewing. Here's what I'd do. I'd store all the tile information in a matrix (Object[][]) with a custom tile class that has the information it needs to retrieve its appropriate image, and certain game related data like slow down factor when a person walks over a certain type of tile, and whether it can be collided with. I'd draw them based on however you decide to angle your tiles. But the important part is you go in this order:
[0, 0], [0, 1], [1, 0], [0, 2], [1, 1], [2, 0], etc., etc....
The idea is if you're turning the floor 45 degrees clockwise, to give the correct illusion of depth, you'll want to draw the furthest back tile first, and the furthest tile forward last. Whether you start on the left or right depends on what angle you decide to work with. At a 45 degree angle, it obviously doesn't matter whether you start on the left or right. But if you guess wrong with your rendering, it will show because tiles that are closer to the "camera" will be overlapped by tiles further from the "camera".
for (int i = 0; i < tiles.length; i++) {
for (int j = 0; j < tiles.length; j++) {
graphics2D.drawImage(tiles[i].getImage(), i*horizontalSpacing - camera.getX(), j*verticalSpacing, camera.getY(), null);
}horizontalSpacing and verticalSpacing will be determined by the angle of your tiles. Set those to match however you make your art.
Drawing moving sprites will be a bit trickier because you'll have to decide which set of axes to follow... meaning, do you follow the axes of the screen, or the axes of your "rotated world." Give that some thought and once you understand what's happening with the perspective here you'll be able to see which is easiest.
So there's your engine ;)
Now, as for the art itself, make them in png format, so that you can have the base of your images be diamond shape, but of course tiles for players and walls and stuff will extend above that diamond. Just don't let them get below the base of their diamond otherwise the tile that gets drawn below them will cut them off. And you don't want a character's feet cut off by the "floor" as he runs ;)
For your final question, don't let java skew the sprite. The only possible way to make it decent is if when you pick an angle, a 3D render takes your 3D world and it's 3D models and re-renders them at that angle; skewing is simply not capable of creating that illusion. The closest you could get is to simply squish the hight of your art to give the illusion that the camera is moving up, but since you can't expose things higher, like the top of your character's head (since the data doesn't exist in the "lower" version), it will be obviously funny looking.
Hope that answers your questions, and good luck! I would definitely like to see what you come up with.

Playing online card games such as euchre or spades

All right here is my problem: I want to play card games online with other users. I'm new to Mac and so far this is my only problem. On my old PC I could go online to pogo.com or anywhere and play a card game no problem. Now I get the room loaded for the game but it's only the outline. There are no users and no tables. Everything is blank. I thought it could be something to do with java, but I'm not sure. I have done software updates, downloaded adobe shockwave and tried numerous different java settings. Any ideas? Am I missing another piece of software?

Rank in a java game

Hi ppl,
I'm newbie in this forum, I'm development a java game and now I would like to implements a rank for players.
Basically, I have some players that play to the game and then (at game finish) game will write a .txt file with date, score and name player.
How I can implements it?
Thanks, regards.
Michael.

then need help in how implements...such as write in a txt file and then apply a bubble sort algorithm?What? You are thinking about it all wrong. Why would you write to a file and then sort?
One thing at a time. Split your problem up into smaller pieces. Sorting your data is a completely different issue than writing to a file, and for that I'd recommend googling comparators and looking up the sort functions of the Collections and Arrays classes in the API (since links don't work for you, go ahead and google those too).

I can't download java games

Hi,
I'm trying to download some cell-phone java games off the internet onto my laptop but a window pops up that says "Java Virtual Machine, Fail to load Main-Class manifest attribute from C:/Documents and Settings..... .jar". I have installed "J2SE Runtime Enviroment 5.0 Update 6". What can I do? PLEASE HELP!

Search the App Store for "Java Browsers".
Therw a re a few there, though support is not 100%, you might be able to find one that can play the games.

N95 Java Games

I've installed some Java games on my N95. The installation went smoothly and they run ok. One problem though, sound doesn't work on any of them. I get sound in all the other apps on the N95 and from Symbian games so it seems to be a Java related issue. Anyone any ideas how I can get the Java on my phone playing audio (I tried another N95 and it worked fine on there so there must be an options somehwre to change it).

I've got Java games that work with audio. Make sure you've got "warning tones" enabled in the profile. If that doesn't help, then it is probably the game's fault.

Java game AI

Hi there, I am currently creating a battleship game which allows you to play against a computer or a human or run the game as a spectator watching the computer battle its own AI. I am having trouble finding an efficient way to program the AI when I hit a ship on the opponents map.
Current logic: I hit an enemy ship and add all the possible directions into a queue and resolve them in order, up down left right. If there is an 'o' (miss) or 'x' (hit), currently in one of the suggested directions, it will be removed (since it has already been searched) and move on to the next coordinate.
Problem: The AI is extensive in it's checking. It finds a long ship, 10 char long, and checkes all around the the ship making sure nothing else is there. Although this method is very accurate, it takes too many turns to verify that it has found the whole ship, therefore losing almost all the time.
Any ideas?
-Thanks in advance
EDIT: Sample from AI vs AI.
x = hit
o = miss

I think you are not putting enough into it.
AI is hard, no matter how simple the game may seem. I have written about 16 games (I might have missed one or two in a hasty count) and worked on a couple open source game projects. Of those 16, 2 of them include an option to play against the computer, i.e. they have a good enough AI. The rest are all strictly multiplayer or single player with no opponents (simulations). Of those two, both are also and where first multiplayer games. That is because until I can play a game enough to fully understand it strategically (even though I wrote it), it is impossible to write a working AI.
So here is my advice, play a few dozen games against other players, the more different people you play against the better. Jot down your strategies in every situation, and ask you opponent if they would be kind enough to do likewise (it helps to tell them it is for writing an AI, otherwise they think you are just trying to learn their secrets for the next time you play). Then try out some of the strategies you get from others and see if you understand it, when it is best to use that strategy, and how well it works.
At this point, you should try to code several of those strategies and see how well the computer does with it. Then code a way for the computer to weigh the possible effectives of the different strategies and randomly choose between them based on the weighted scale. As in, if start A is 5 times more likely to succeed than strat B in situation X then the computer should have 5 times more likelihood of choosing strat A over strat B for situation X.
As a starting point, here is my strat for battleship in a way that should help with how to code it. I always look at which direction has the longest distance to where I have previously fired. But I also limit it to 4 spaces as that is the length of the longest ship (plus the one hit). So if I choose say F6 (isn't it letters across the top?) and get a hit, then I look around F6. Looking down I have already gotten a miss on F9 leaving 2 blank spaces. Looking left I have recorded a miss on A6, leaving 4 spaces that way. Looking up I have a miss on F5, so there is definately not one that way and this makes it less likely the boat runs north and south (up and down). To the right the nearest shot was a hit on a boat I already sunk but it is 7 spaces away, so I exceed the limit and reduce it to 4 spaces. So what do we have, 2 spaces down, no spaces up and 4 spaces to both the left and the right. At this point I am just going to randomly choose to go left or right and keep going that way until I get a miss or my opponent announces I sunk a ship, if a miss with no sinking I go the other way until said declaration. Should I get a miss on both sides without an additional hit then I will re-evaluate and since the only way left to go in that case would be down, that is how I would go. If I got a hit going either way but missed on both sides then I know I have two ships and I simply put the new hit on the back burner until I have sunk the first.
Now this should all be relatively easy to code and should make the AI much more formidable. But there is actually far more I do when playing that game. For example, if the 5 length ship has already been sunk and the longest left is 4 length, then I only go 3 blank spaces each way in weighing my options. Similarly if the 2 length ship and both 3 length ships are sunk then I first check to ensure there is a total of at least 4 spaces along either axes (there must be on at least one of them). This will be a little more coding work, but will make the computer AI even more robust and formidable.
If I was playing against your AI I would always place my ships from left to right, because I know the AI is then always going to waste at least 2 shots whenever it gets a hit. In AI the more unpredictable the AI is the better, this is why it is important to keep things random, and give the computer as many strategy choices as possible to weigh and then semi-randomly choose from.
Also, this is the wrong place on these forums for this question, there is actually a java games section here, I think it is under other. Also there is actually a fairly active java game forum, but I don't recall the url for it atm. You will have far better chances of getting a response in one of those more appropriate places.

I updated my firefox and now am unable to play ANY pogo games

I updated my firefox browser and now am unable to play ANY pogo games. and yes my java is up to date

Hi..
If you are referring to video streamed on YouTube or other sites that require the Flash plugin, try troubleshooting.
Quit Safari.
Open System Preferences > Flash Player then select the Storage tab. Click: Delete All
Now uninstall the Flash plugin then reinstall new > Troubleshoot Flash Player | Mac OS
Very important to uninstall the currently installed Flash plugin first.
Relaunch Safari. From your Safari menu bar click Safari > Empty Cache
Now try a video.
BTW... if you have the ClickToFlash extension installed, that can prevent Flash based video from streaming. It can also be installed as a plugin in /Library/Internet-Plug-Ins.
And check to see if Safari is running in 32 bit mode. Right or control click the Safari icon in your Applications folder then click Get Info. If the box next to: Open in 32 bit mode is selected, deselect, quit then relaunch Safari.
Tip... when you post for help, please tell us which Mac OS X you have installed

Why does my iPad Mini Retina Display battery drain so quickly? I will be playing some 3d games and it says the battery is 90% but I'll turn off and turn in back on it about 30 minutes and the battery is only 70%. Why is the reading so inaccurate?

I will be playing some 3d games and it says the battery is 90% but I'll turn off and turn in back on it about 30 minutes and the battery is only 70%. Why is the reading so inaccurate? I understand that 3d games on high brightness will drain my battery quickly, but why doesn't it tell be how low it is to begin with? The other night it said it was around 35% and I turned it on in the morning and it was only 3%?

Sorry there are some typos above, but you should be able to figure out what I'm asking. Let me know if you have tha same problem, know how to fix it, or know if apple is aware of the problem and is adressing it in a future update.
