mmm, looks impresive

Durty auld Morris drums... they're fu*kin' great!!

Excellent work for a first Java applet! Nice one... loads nice and fast too

I managed to bounce mine into the UI... do I win a prize?

nice.

:P yeh hobbes, unfortunatly the balls can move below the bottom of the area they are confined to by (their speed)pixels

gah.

well to fix it would take some code, and i am finished with that applet now, im making my game now :0)

Well that's definitely a good start, nice one. I'm sure you won't have any problem making your game

The shame of it all, I wouldn't know where to start to get that thing going, which is why I would like to know if there is any chance of getting the code from you.

If yes thanks a lot and I'll owe you big, if not no biggie, you'll have my respect always anyway, that is absolutely excellent.

good stuff.

not as l33t as my java scribbling applet, taken line from o reilly's java examples book!

thats lovely - really smooth.

nice one.

i have the applet files on my u:\ drive in college, and on a zip disc, but i have no zip drive at home

) there is very little code to get the applet working

a particle is made up of a point and a vector,

when it hits the side walls the j element of the vetor is multiplied by minus the "bounce", and when it hits the top or bottom the i element is multiplied by minus the bouce.

to get gravity, i assume the particles have a mass of 1g, and simply add a vector g with magnitude 9.8 downwards to it every second (in actuall fact i add 1/50 time 9.8 to it every 1/50 seconds)

Are you people using OpenGL with Java for those applets?? If so, what's the performance like? Does it use hardware acceleration? Can anyone post a link to some sample code? I'd like to see if I can port my engine to java (and how slooooow it would be).
