Very Happy

this has to be the best one you've done yet. Very very impresive...

come on PrInCe_, let Catalyst do what he does best. He's awesome at programming and we all can learn a lot from him.

What is your will master? Rolling Eyes

Seriously though, this is incredible. The turing comunity benefits from you.

Just curious, where'd you learn how to program?

You should try to make the falling pixels reflect at the angle that they hit the ground. Nice work though Very Happy

i learned to program at BRDHS in essex, illl try the falling pixels, i have an idea hwo to do it

Post subject: 

That's cool, wish ya luck...I'd just check the pixels to the left and right of it...oh, and make the bouncing pixels bounce a bit too Surprised

Post subject: 

they have the capabilty to bounce more (they have a life span) but i cut it off so i could have a constant stream of particles

i owudltn mind seeing the code for that Very Happy

here a modded version of the one i posted
i call it rain,
ull need to pics from the first post but here the exe....

left click to make that area impassable, then right click to make passable gain

Hmmm, Nice work, what about making a version called snow?....perhaps the snow could stay on the ground forever, and pile up....then it would really be a canadian program,...... Eh... (sorry, couldn't help myself.)

No but seriously, I wouldn't mind seeing a snow version, if its not too much work.

wont be much work, changing the first one to rain only took like 5 lines
ill give it a shot

Author:  Catalyst [ Mon Apr 14, 2003 8:22 pm ]
Post subject: 

woo!
i did it, snow
20min
it is completely inefficient and eventually slow to a halt but it works
i know a btter way to do but it takes too much time to debug

did you inlcude all the files? it did not run on my computer Confused

Author:  Catalyst [ Mon Apr 14, 2003 8:35 pm ]
Post subject: 

you have to use the files from the first post with it

Thats wicked....does tend to eat a bit of cpu, and memory, lol.

98% cpu right now
14mb of memory...

thats only after 3 minutes of running

well dont i look dum, lol.

any way that is one of the most impresive things i have see in truing. you got some good skills there Wink .

wow, very nice catalyst Very Happy

Post subject: 

i fixed it!!!

it is stable now, altho the moon erases itself....

Author:  octopi [ Mon Apr 14, 2003 10:46 pm ]
Post subject: 

NICE, no more memory problems, ....who cares about the moon anyways, lol.


for those interested in pointless facts:
it took 1 minute, and 47 seconds for the moon to completely disappear.

Still runs at 98-100% cpu (but what turing program doesn't)
And it stays at a constant 12,740K of memory.

nice work!

wher r u gettin this info from octopi

Author:  octopi [ Tue Apr 15, 2003 3:29 pm ]
Post subject: 

The cpu, and memory?

From taskmanager (windows nt,2000, xp)
Press control-alt-del, and then the arrow key right 4 times, then press enter, or just click where it says "Task Manager", you then want to click on the "Processes" tab, and then look for snow2.exe, or what ever program you want to know about, and then just look at the information it shows about it.

just taking a look at some old programs and this is the most amazing!
hey, i'm new here

Post subject: 

hmmmm... nice work...
but one thing... there's a change u could make in yer bouncing:
no mather where the particle hits it bounces the same way, for example if it hits a perfectly flat surface or a verysteep surface it will bounce back the same way =/

i know
i decided to take the lazy way out and not do real collision physics
