IrrNetLite and PhysX Controller Update (All PhysX Updates)

Post by sysgod »

Hi! I need some info about IrrNetLite .

I have server based physics on NVIDIA Physx engine and i need to replicate object updates

but i have a server CRASH even when i update a character O_o

my crash code is here:

//from default packet handler
case EPT_CHAR_UPDATE: // sends when character physics updates //on client

char_update=0;
packet >> char_update;
ServerMessages=" Incoming For ID="+Ogre::StringConverter::toString(char_update);//debug text

player[char_update]->UpdateCharacter(deltatime);// "char_update" is right
// and text tells that packet not lost

break;
player[char_update] exists on server

I have the same packet handlers for input but they work fine.

If somebody worked with physX and irrnetlite? tell me please what are my errors?

:shock:
ServerMessages=" Incoming For ID="+Ogre::StringConverter::toString(char_update);//debug text

BLASPHEMY !!!

These posting a code of Ogre on this forum!
:lol:

Now really, could you post more code? seems to be missing something.

IrrNetLite and PhysX Controller Update (All PhysX Updates)

:roll:

update function:

Code: Select all

           void myPlayer::UpdateCharacter(NxReal deltaTime)
{
          

gworldRay.orig = NxVec3(this->actor->getGlobalPosition().x,this->actor->getGlobalPosition().y,this->actor->getGlobalPosition().z);
gworldRay.dir = NxVec3(0,-1,0);
gworldRay.dir.normalize();
this->actor->getShapes()[0]->setFlag(NX_SF_DISABLE_RAYCASTING, true);
NxShape * s = gScene->raycastClosestShape(gworldRay,NX_ALL_SHAPES, hit, 1, 50000.0f, NX_RAYCAST_SHAPE | NX_RAYCAST_DISTANCE);
this->actor->getShapes()[0]->setFlag(NX_SF_DISABLE_RAYCASTING, false);

	NxVec3 disp = NxVec3(0,-9.8/2,0);

	if (this->PxPushCharacter)
	{
		
		NxVec3 horizontalDisp = this->PxCharacterVec;
		horizontalDisp.y=hit.worldImpact.y;
		
		horizontalDisp.normalize();
		NxVec3 worldVec=this->actor->getGlobalOrientation()*this->PxCharacterVec;
		disp += worldVec * this->Speed * deltaTime;//horizontalDisp
	}

NxF32 height = GetHeight(deltaTime,this->id);
	if (height != hit.worldImpact.y)
	{
		disp.y += height;
	}
	NxU32 collisionFlags;
	this->PxSelectedController->Move(disp, collisionFlags);
	
	if (collisionFlags & NXCC_COLLISION_DOWN )  
		StopJump(this->id);
	
	this->PxManager->updateControllers();
}

Works fine on clients if I use it out of this :?

Code: Select all

virtual void handlePacket(net::SInPacket& packet)
	{
		// The packets will use a single char to store
		// the packet identifier, remember to use the
		// smallest possible datatype for storing your
		// packet identifiers. c8 is a typedef for char.
		c8 packetid;
		packet >> packetid;
        int playerID = packet.getPlayerId();

		// Here we will switch based on the packet id.
		switch((E_PACKET_TYPE)packetid)
		{
		case EPT_ROTATION:
			f32 angle;
			packet >> angle;
			player[playerID]->userInput(angle);
			//
			break;
		
		case EPT_INPUT:
			player[playerID]->userInput(packet);
			break;
		case EPT_CHAR_UPDATE:	
		
			 char_update=0;
			 packet >> char_update;
			 ServerMessages=" Incoming Update For ID="+Ogre::StringConverter::toString(char_update);
			break;
		}
   
	
	}
Idea to Update from player's packet grown in my "broken mind" after attemp to update all controllers in "for" loop as I did with rigid bodies...

second or 3rd idea was to make a loop with "if" searching a Online player slots

somthing like:
for bla..bla..bla
{
if (Online[ind]==1) player[ind]->UpdateCharacter(deltatime);
}
//endfor :)

No one moved....

then I do such a thing ... I added my Update function to the end of input ...and what do u think happens? Players move if I hold a key I can hold "Jump" and player updates but if i unhold key it stacks in air forever..

this is my Input function (for testing only):

Code: Select all

 void myPlayer::userInput(net::SInPacket& packet)
	{
		Real step;
		Vector3 WallRaYDirection;
		Vector3 PlayerOldPosition=this->plNode->getPosition();

			//mouseRay.setDirection(PlayerCamera->getDirection());
	        
            mRaySceneQuery2->setRay(mouseRay);
			
            RaySceneQueryResult &result = mRaySceneQuery2->execute();
            RaySceneQueryResult::iterator itr = result.begin();

           if (itr != result.end() && itr->movable && itr->movable->getName().substr(0, 5) != "tile["&& itr->movable->getName().substr(0, 6) != "Caelum")
