Thank you.

Hi,
I must be stupid, but i can only download PhysX SDK 3.1.2 and 3.2...
And i don't find nxCharacter.dll
How can i test the examples physx-samples without that ?
Thanks for advance
Greg

You need the 2.8.4.6 SDK.
I just logged in to the NVIDIA dev support site, and I can download the 2.8.4.6 SDK for Windows.

by **benicourt81** » Sat May 19, 2012 5:22 am

Thank you, but i don't find this SDK anywhere.

The adress is : http://developer.nvidia.com/rdp/physx-downloads
And there is only SDK for PhysX 3.2 (beta 3) and PhysX 3.1.2.

I'm also logged as a developper...
Could you help me ?

Is there a flag to disable a character controllers gravity, if so can you please post it.

There is no such flag. We use the default implementation for the stepping algorithm, and automatically apply the scene's gravity.

Well do you know how i could make the character controller climb a ladder?

by **enn0x** » Mon May 21, 2012 8:10 am

Good question. I didn't think about this before.

1.) One idea would be to remove the controller from the simulation while the player is climbing a ladder, and replace it with a plain kinematic actor.

2.) Another idea would be to use an invisible support below the character, which is moved up and down while the character climbs.

3.) A third option would be to store a "custom gravity" vector as member on the character controller, and if this custom gravity is set we use this one (and not the gravity we get from the scene). Would not be much effort, but I don't know if this approch really works.

Perhaps you start with the first idea, and if it fails we try the thrid one.

by **Pataua101** » Tue May 22, 2012 4:52 am

I wrote a gravity member and a set gravity function and built myself and it works well.

Thanks for help.

Is it normal ?
Thanks,

by **enn0x** » Fri May 25, 2012 3:38 am

It seems this question has been asked a lot, so they (AGEIA/NVIDIA) have placed a FAQ right on the page you have posted (http://devsupport.ageia.com/ics/support/default.asp?deptID=1949).

Look for "FAQ's" on this page, then "How to download binaries and tools?".
I don't think I could describe it in a better way than in this FAQ.

by **benicourt81** » Sat May 26, 2012 12:12 pm

Ok, thank you for your efforts
i don't find it, and the FAQ don't help me. I think they haven't activate my downloads... i've posted the same question on their forum. We'll see.
Somebody has perhaps another link to ?
Greg

by **enn0x** » Sat May 26, 2012 5:45 pm

Hmmm... the FAQ mentions several steps to follow. Where exactly do you get lost?

by **benicourt81** » Sun May 27, 2012 1:38 am

"Expand +Download" but nothing about the SDK here

by **enn0x** » Sun May 27, 2012 5:33 pm

But it does expand from "+Downloads" to "-Downloads"? And there are no items below it, or are there? If so, list them.

Please answer all of my questions.

On the left side, below "Support Downloads", are you able to expand "+Downloads" to "-Downloads", and what items do you see listed below "-Downloads"?

by **benicourt81** » Wed May 30, 2012 10:56 am

Sorry, i can see :

Support Downloads
- Downloads
* PhysX Testing Guide

Thats all, no other download !

by **enn0x** » Wed May 30, 2012 2:46 pm

Ok, then you are looking at the right place, and you have javascript enabled. There should be more items on the same level as "PhysX Testing Guide", amgong the the download folders for "PhysX SDK 2.8.4", "PhysX SDK 3.1" and "PhysX SDK 3.2". Looks like a case for the NVIDIA guys.

by **benicourt81** » Thu May 31, 2012 3:14 am

ok, thank you. I abandon physics with panda - too difficult to get the good sdk...
bullet seems to be a better alternative.

if u sign into the old support centre "you have to be signed in".
1.click online support
2.click downloads next toknowledge base.
3.click downloads in left hand bar
4.select version to download.

@Pataua101: thank you,
but look at this :

It looks like you haven't been granted the appropriate access by NVIDIA. For me, the list under "Downloads" also lists various SDK-related options.

Yes, and since i've asked with other identities, and i've the same results.. probably they don't want to distribute the old sdk to new users...
if somebody could give me a link for download in PM... it would be very nice.

by **enn0x** » Tue Jun 05, 2012 4:25 am

It is - accoring to the NVIDIA license - not allowed to re-distribute the PhysX SDK.
This is why we require users to download the SDK themselves.
Sorry.

Yes, i know that,but it's ridiculous in this case, and it's why i'm talking of PM (i'm not a NIVIA vicious guy, my panda3D account is not new

)

by **rdb** » Fri Jun 08, 2012 2:58 am

Distribution of the SDK outside the accepted NVIDIA license will not be discussed on these forums.

Hello,

If I use Physx with Panda3d, does my python code is always multiplatform (Linux, windows, mac...) ?

by **enn0x** » Thu Nov 15, 2012 4:50 pm

Yes, in theory.
But I don't know if we still provide builds with PhysX for Linux or OSX. You might have to compile yourself.
