Something that could help

I was working on a FPS game. Had a fast startup but then some "more important" thing catched up. Well, so far so good. Here is what i got finished:

A basic physic environement based on newton. I like the design pretty much, could be a good starting point for any application that will use Irrlicht and a physic engine. I had a problem with the OnDestroy event and joints are not implemented. The OnDestroy event sould be solved with a quick post in the newton forum, the joints stuff is something i will work if i get some sparetime

.

Some cool SceneNodes a explosion node (you may want to add a SizeAnimator here, will look much better). Furthermore some other things, that may be good for a look at.

The last thing i was working on was the player class with its armament but the design i used to have was bad. Ill do something better (in my sparetime

).

So how is all the stuff supposed to work. Well, you can have a look at the docu directory there is a doxygen generated documentation.

Short explantion:

There is a physic manager and some nodes. Each node can un/register itself to the physic manager and is now affected by physics and receives all the events coming from the physic manager. There is also a nice material setup you might want to have a read through, its quite powerful.

If you have any questions about the source send me a mail Friedrich.Schick@web.de or post it as a answer to that thread.

Be sure to have the newton and the irrlicht sdk installed.

Here is the download http://www.bluffel.de.vu/files

It will probably take 30 minutes from my post until you can download the file, due t-online my provider.

very interesting!!!

Newton seems like a nice and easy to integrate physics engine. I am reading some tutorials right now.

Is it open source?

I see there's a free version (old) 1.22. Unfortunately there's no link to download it. Do you know where I can get it?

The latest version 1.51 is being used in 3dgamestudio.

interesting, thanks for pointing it out.

ps. I'll download your files when they're ready.

Hi schick, i'm happy that you still working on coengines.
I found your work very useful. I saw the classes in helpfile, and can to say, that there many useful things.
Unfortunately I use devcpp and have not MSVS net.
I'll try to compile your sources with devcpp. You said, that usually not uses MFC

afecelis, here is the link for newton sdk, but only v 1.2 is free /not sure/

Hi schick,
I've trying to compile your sample with devCpp an MSVisualC++6, but always get linker errors with co classes.
Can you explain, how to setup your classes?

The problem was solved.
I forgot to include some files in project.
Now coEngines runs with VC++6 and DevCPP.
And now is time for me for reading of help file

etcaptor:

there's no active link for downloading it. Have you got a copy?

thnx!!!

I think thats schick's link is still active:

http://jens.schick.bei.t-online.de/file ... source.rar

He uses MSVStudio net.
I hope, that he will continue your work.

Schick,
Something about 3th person camera with your classes?

By the way for ICoFireExplosionSceneNode, I get 'ICoFireExplosionSceneNode' : undeclared identifier,

Schick,
I found that ICoOctTreeSceneNode not works properly with q3bsp compiled map. When testmap->registerCoNode() is started, application crach.

I assume that is some related with function create CoStaticMeshNode() in IcollisionNode.cpp. Any comments?

I found that this happend when some bsp texture are missing, or any bsp texture folder is missing

heya schick, very impressive, a neat idea making the character themself be affected by physics.
I had to make one small change to get it to compile with the latest version of the Newton SDK available from newton's site.

in ICollisionNode.cpp i had to change this:

Code: Select all

//i think what this is meant to do is to remove the object from simulation if it stis still too long, im guessing 60 frames sitting still is enough (1-2 seconds??)
		//i had to cerrect this function call because the interface for this feature seems to have changed since whichever release of newton the original guy was using
		NewtonBodySetFreezeTreshold( CoBody, /*freeze_accel_mag, freeze_alpha_mag,*/ freeze_speed_mag, freeze_omega_mag, 60); //60 is a guess

after that it compiled and worked normally (i t//hink anyway....seemed to)

thought that might be somewhat useful...

"a neat idea making the character themself be affected by physics"

woah

hmm...as the x blender exporter gets a bit better, I PERHAPS will be able to rig my arena model there and export as x weighted. For the whole comunity.

yesterday I made another test, using the wonderful "paint weights" feature of Blender.

physics in characters...is it ragdoll? or newton physics..

Irrlicht Engine
