newest good game would be read dead redemption on the ps3, brilliant game, other good games going back in time would be... tir-na-nog on the spectrum, ik+ on the amiga, syndicate wars on the ps1, civ 1 on the pc. it seems to me as graphics became better they seem to forget about the gameplay, oh and startrek armada on the pc  ,... c&c tiberium sun on the pc |

YES exactly like that , now to sift through your program to pick out the maths bit, thank you !! update.. typical..it wasnt the maths after all, i was that thing when you get variable interference from somewhere else in the program, i was zeroing out a 2d array just before my loop started i put it after the array had found a pixels and hey presto it worked, btw thats some weird for loop you use, that form scares me because i dont understand it..haha 1

hey everyone, i am stuck and rapidly running out of ideas with my maths problem, any pointers would be great.. consider the following... a screen is filled with random pixels the following code only half works and i have tried everything i can think of to get it working but i am at a loss. the pixels on the left hand side move outwards at an angle from the center of the screen,,,perfect just what i am looking for.. but the pixels on the right hand side when i alter the code do the following go in to the center...dont move at all(code on show) or dont even show  1

I once made a game with fps creator and made it so you had to shoot a portable toilet through a hole in the scenery, you only had limited amounts of ammo, and the objects were super light weight as the levels increased the holes got smaller..haha great game shame it wont install on my new computer

Game Development / Newbie & Debugging Questions / Re: applet downloading media
|
on: 2010-04-28 17:31:15
|

I may be off the mark when i say this but from my experience i used the approach... players run the applet on thier computers then if its signed you can create a directory for your game and download what you like into it(images,music etc).my sprites were massive 10mb each and i didnt want a player to download them every time they ran it. you can check the date of file creation so if its newer then it will download it off the server if not it skips it, of course all this is done in the background at a time when performance doesnt matter.

LOL it was a belkin router it always played up sometimes it would let me login, other times it wouldnt i thought it was because i was running my web server but it was just a rubbish router i have setup my new netgear router and the test code is working perfect again But it wont add a port (invalidAction error)theres too many parameters for the netgear on netgear you need... Whats it called ? what type ? start port ? end port? local address ? going to have a look at the docs see if i can work it out. EDITi took out these lines.. 1

Its only a waste if you personally think its a waste.
I have enjoyed my little journey into the world of java and games programming, although i was addicted to it i have learned to keep things more balanced.
I now spend quality time with my wife when i am not working, but i cant help but thinking of how i could improve my methods and speed up certain parts of my game which i have totally ripped apart ready for round 2 in march (when wife goes back to work and she stops moaning that i spend every single second programming and learning..lol).
Have i wasted all my time learning java ?...No i am a little wiser and i learned how to do things in moderation.
No matter what you do in life, even if nothing comes from it other than entertainment its never a waste of time :O)

Game Development / Newbie & Debugging Questions / Re: Java read/write to a text file on my site for highscores
|
on: 2009-10-08 17:30:47
|
|
I dont know if this is the best way to do things but it worked for me.
i have a plain text file on my server for highscores, clients(applets and applications) can access this file(readonly).
they either do it directly using the http protocol or they can do it by passing a message to the java server application requesting the highscore data.
when it comes to updating the highscore they pass another message to the server application,the server application verifies the username and password and will update the file(i acually update a mysql database and get the server to periodically overwrite the text file).
so the clients access the file on the server by requesting the data from a java application on the server.
to display the data on the website i used php to read from the text file and display it.
I never let my clients alter files on my server directly they always have to verify themselves to a java application.
Word of warning if you try to do too many http calls too quickly your server will think its under a denial of service attack and you wont be able to read anything.

Add your game by posting it in the WIP section,
or publish it in Showcase.
The first screenshot will be displayed as a thumbnail.

, may be i will experiment next year with it , as im too wrapped up in the understandings of adding user defined classes into linkedlists and manipulating the contents..so much to learn !!
