AS3 Fisix Engine

Up until now I kept this one in the physics forums but since my physics engine (The Fisix Engine) is nearing alpha release, I wanted to let all of you flash game coders know about it. The engine is built for speed and games and uses verlet physics. When released, it will be free for all

Here's the latest demo
http://www.fisixengine.com/demos/demo5.html

and the official site
http://www.fisixengine.com

I'm still in development stages so it'd be great if you could let me know how well the demos are running on your machine

Woah! That's cool man!

Just a thing though.. was it realy needed (speed wise) to use AS3 for this? Or wouldn't it matter too much?

that's... very impressive!

Definitely. AS3 can be up to 20 times faster.
...I should post some demos of the as2 engine to show how ridiculously faster player 9 is

Very nice, good speed, no problems at all running it :)

kinda reminds me of this thing i saw at YugoP i think similar concept... Very cool stuff it ran 20-28fps on my comp ran very smoothly. the semi-automatic version on his site can keep me entertained for hours it seems...

That is preaty darn nice... I was running preaty close to 26- 28 consistantly.

I had 28 - 30 fps consistanyl, geez that are good

Alright SaphuA, I dug up an as2 demo that was posted here a while back
http://studio.fileitup.com:88//Fisix...collision.html
(press ctrl, shift, and alt)

Now compare that to any of the demos in as3, you can definitely see the speed improvements done for player 9

knowledge is power :)

Thanks a lot mate ;)
Finaly some actual prove..

Thats incredible, although it was running at about 20fps it seemed really smooth. Sure beats 1 fps in the other example :) Very nice work

release date

I'm very glad to hear that you guys are getting smooth simulations on your computers with this. I've also been thinking about a release date, and it would be ideal for me to release an alpha version by the end of this month

I really want to add two more things to the engine though: wheels and friction

so that's my target date, it also involves writing some documentation and getting started tutorials

I'm also debating whether to go with verlet integration or not... right now i'm using verlet but it wouldn't be too difficult to switch to euler. I'd like to know what you experts here think. remember that I'm going more for speed than accuracy, but I still want it to look good

I won't be releasing the source for this, so there might be a problem with using the library in flash 9 authoring (because it doesn't allow the use of .swc files in the beta)
for those of you who don't know yet, swc files are a little like java .jar files--they are packaged code or components

swc's can be easily integrated into flex, so I'm also wondering what you guys are using for compiling as3 code-- flash 9 beta, flex, or maybe good old command-line ;)

I appriciate all the help

Not sure if I am expert, still building my own verlet engine, but what exactly could be wrong with verlet integration?

pretty much friction and collision reaction

it would be easier to do with explicit velocity values
...still debating :)

Very very well done! :smoov: :thumbsup:
It's also a great benchmark for the FP9 and it's nice to see that it's finally handling quite complex physics so smoothly.

Keep up the very good work

Flash 9... Too bad I won't be able to try this out then :(

I'll do my best to find a way to get it to work on flash 9, cause that's what I like using better too :)
but you can always try it out on flex, and when the real version of flash 9 comes out swc support should be availalbe

Then why don't you make a compiled swf out of it, so we can add that to a project (either in the library or using Loader)? I'm not sure if it would work, but it might.
