Anyone using Java here?

[relsoft]

I'm a little over 3 weeks into learning the java language (need to since a publisher wanted to publish one of my  games to android).

At first I hated it, but after a few hours I learned to like it. 

The way a approach my learning is to make a game (weird) but it helps me to learn the language in a faster pace and I used Java2D (instead of OpenGL) to do the GFX in order to force me to learn the intricacies of the language.

So far, here's what I've done:

Notes:

BTW, Does this thing stutter on your setup? If it does, how about the no sound version?  Does the no sound version still stutter?

Comments on code are welcome.

I used to do Java years ago when I was at college but I hate it as I was struggling with it...

Java2D could be interesting and I guess it is easier than C++ but not sure about C++ with game library(Such Allergo, SDL and So on) thought

holly mother!!!

lol your bullet hell engine is incredible (eyegasms to be had). i've not run it in years but its come on a long long way.

how do you find java 2d?! i done a course on java about three years back but it was all focused on the language itself. by the end of the course i vowed id never touch it again lol. looking at this defo has me interested again though.

awsome stuff as usual rel.
esp as its in java.

I salute anyone who can code in Java - I find the development kit to be confusing.

Either I'm missing something simple or you guys are geniuses.

I use Java in work as the real time pricing rules that sit between our broker software, web services and comparison sites are written in a rather unusual combination of Java and Drools..  Because of the strange combination, Eclipse does not generate any compile errors, it's used purely as a text editor! The rules are compiled using Apache Ant and the only way to debug code is to be very, very careful when writing it and then use loggers in the code to trace through and see where it fell over if it crashes in the test environment.  I've done this for the last 2 years now, it's not too difficult but it was a steep learning curve at first... As for graphics in Java, I wouldn't know where to start!

lol that sounds like fun Sw... do you find your self doing the one eye closed one eye half open as your testing code out?

I've never actually put a catastrophic bug live into the system but the potential for harm is really high so putting new pricing rules is a very, very scary thing knowing that there are thousands of requests an hour hitting our web services I could blow a lot of money in one go!

Thanks guys!!!
I've updated the engine and decided to make a little game out of it(WIP)

I also used a "recycling" technique so that there would be no heap allocs in-game.  GC should not kick in while in-play.

Please tell me if it still stutters.

See first post.

hey rell thats awsome mate!

i do get stuttering however, its happening at periodic times maybe every 10 seconds im on an i7 3.4 cpu so its not that.. at a guess it feels like the vm is doing some processes thats conflicting with your game at those periods.

top stuff though!

Nice. Very Cave-like.

I'm using Java2D to re-create basic demo techniques as well.
