hi,
i wanted to access userdata but in ogre3dbody there is no userdata and when i use getnxactor()
compiler says there is no actor defined , i want to know how can i have my own userdata for a body?

thx

It is used by NxOgre.

If you want to attach your own stuff to the Actor then you should use inheritance.

hi,
i didnt want to spam another topic

where is contactnotify in nxogre
is there any contact callback ?

betajaen

In Bleeding there is.

In Bloody Mess, I've just finished most of the code and it requires testing. It should be up on the Git Repo in a few days.

Can't delete Volumes.

I'll add a deleteScene function to World and publish it in the next commit.

Thx, is NxOgre::Enums::VolumeCollisionType_OnPresence working?
i just test it .. but it seems it dont work!

?? It really dont work

Negative, it DOES work. Just tested it with the commit 5efd6b4246e633f5f2ba1a9574ab34d3a014393f.

void onVolumeEvent(NxOgre::Volume* volume, NxOgre::Shape* volumeShape, NxOgre::RigidBody* rigidBody, NxOgre::Shape* rigidBodyShape, unsigned int collisionEvent)

{

	if(collisionEvent == NxOgre::Enums::VolumeCollisionType_OnPresence)

	{

		Beep(1500, 5);

	}

}

It is correctly "beeping".

thx,i'll check it!

Does it work now for you? I saw your new post before you deleted it. Is it solved?

If not, doublecheck that you really never stop by inside the OnPresence if-statement by setting a breakpoint there.

betajaen

26-08-2009 23:22:19

Actually your meant to compare the flags and enums like this;

if(collisionEvent & NxOgre::Enums::VolumeCollisionType_OnPresence)

{

	Beep(1500, 5);

}

In case you have multiple flags.

spacegaier

Okay, good to know! In case that I needed several events to be handled, I would have checked for multiple flags in one big if-statement...

it didnt work ...
i tested it with Commit http://github.com/betajaen/nxogre/commit/6c7e255c586957e226b286361ad19d8a2ece2783
and now i have these! :oops:

You properly build NxOgre and linked everything for sure?

asvsfs

27-08-2009 13:33:49

yeah i think! i downloaded the (commit) and compiled it and used it...

spacegaier

27-08-2009 13:52:28

I'll test it at home with the latest commit if it works, but I'm rather sure that it does.

asvsfs

28-08-2009 07:19:29

did u test it?

thx,

OnPresence works with the latest commit (I just took my tutorial 4 code and added the OnPresence Statement).

asvsfs

28-08-2009 08:29:07

thx, it worked for me too(for tutorial 4) there must be something wrong with my code because it still dont work there!! but onEnter Works Well!

spacegaier

28-08-2009 08:44:14

Could you show us your onVolumeEvent()?

Do you still get the linker errors or does it at least run now?

asvsfs

28-08-2009 08:56:08

no i dont get any link error now.. but it doesn't work

void onVolumeEvent(NxOgre::Volume* volume, NxOgre::Shape* volumeShape, NxOgre::RigidBody* rigidBody,

								NxOgre::Shape* rigidBodyShape, unsigned int collisionEvent)

	{



			if(collisionEvent == NxOgre::Enums::VolumeCollisionType_OnPresence)

		{

			

			if(mTimer->StopWatch(1))

			{

				MessageBeep(0);

			static_cast<ATower*>(volume->UserData)->Attack(m_pSceneMgr);

			}



		}



	}

And you are sure that you never stop by inside this if statement (checked via setting a breakpoint there):
if(collisionEvent == NxOgre::Enums::VolumeCollisionType_OnPresence){}

If not: You are cretain that your event firing object is in your volume (checked via Visual- or RemoteDebugger)? So, onVolumeEvent() definetly gets called sometime.

asvsfs

28-08-2009 09:15:48

yes it get inside of statement and object is right and even onenter event works well when object enter the volume but OnPresence doesn't work!
it get into OnVolumeEvent Just once.

spacegaier

28-08-2009 17:16:46

yes it get inside of statement
Inside the if-statement = it is checked or are you actually landing in the part inside the curly braces?

it get into OnVolumeEvent Just once
And then?

betajaen

I can confirm Volumes work in the latest Git:

mScene->createVolume(new NxOgre::Box(4), Matrix44_Identity, this);

void CakeApp::onVolumeEvent(Volume*, Shape* volumeShape, RigidBody* rigidBody, Shape* rigidBodyShape, unsigned int collisionEvent)

{

 std::cout << collisionEvent << " vs. " << NxOgre::Enums::VolumeCollisionType_OnPresence << std::endl;

}

Result:
4 vs. 4

The problem is your code. Most likely that nested if statement.

28-08-2009 20:50:04

...! i dont know every thing works well for onenter or onexit...
OnPresence works well in tutorial 4 ... but doesnt work in my code!
there must be something wrong with my code but what ! i'll working on this problem more..
thx for your help

Can't delete Volumes.

I'll add a deleteScene function to World and publish it in the next commit.
