Smooth mixed 1st + 3rd Person Camera Scene Node (for RPG)

[m3ltd0wn]

thus the camera works like a charm, seems i can't get IrrNewt to make the character to collide with other stuff in the world i haven't sleep all night trying to figure out how to add phisycs to the actor mesh and in the same time to use this camera ...


here is my code:

Code: Select all

p_world = createPhysicsWorld(device);
	
	// add terrain scene node
	scene::ITerrainSceneNode* terrain = smgr->addTerrainSceneNode( 
		"media/terrain-heightmap.bmp");
	terrain->setScale(core::vector3df(10, 1.1f, 10));

	terrain->setMaterialFlag(video::EMF_LIGHTING, false);
	terrain->setMaterialTexture(0, driver->getTexture("media/terrain-texture.jpg"));
	terrain->setMaterialTexture(1, driver->getTexture("media/detailmap3.jpg"));
	terrain->setMaterialFlag(video::EMF_BACK_FACE_CULLING,false);
	terrain->setMaterialType(video::EMT_DETAIL_MAP);
	terrain->scaleTexture(1.0f, 30.0f);
	
	//create terrain body
	irr::newton::SBodyFromNode terrainData;
	terrainData.Node=terrain;
	terrainData.Type = newton::EBT_AUTODETECT;
	terrainData.TerrainLOD = 1;
	terrain_body = p_world->createBody(terrainData);
	terrain_body->setMass(5.9736*1000000000000); //earth's mass
	terrain_body->addForceContinuous(vector3df(0,-9.81,0));	
	terrain_material=p_world->createMaterial();
	terrain_body->setMaterial(terrain_material);

	//create an actor to test the rpg camera
	scene::IAnimatedMeshSceneNode *actor = smgr->addAnimatedMeshSceneNode(smgr->getMesh("media/sydney.md2"),0,-1);
	actor->setMaterialTexture(0, driver->getTexture("media/sydney.bmp"));
	actor->setPosition(vector3df(280,56,693));
	actor->setMaterialFlag(video::EMF_LIGHTING, false);
	actor->setLoopMode(true);
	actor->setMD2Animation(scene::EMAT_STAND);

	//create actor body
	irr::newton::SBodyFromNode actorData;
	actorData.Type = newton::EBT_AUTODETECT;
	actorData.Node = actor;
	actor_body = p_world->createBody(actorData);
	actor_body->setMass(56.f);
	actor_body->setCentreOfMass(vector3df(0,-1,0));
	  //actor_body->addForceContinuous(vector3df(0,-9.81*actor_body->getMass(),0));
	actor_body->setContinuousCollisionMode(true);
	actor_material=p_world->createMaterial();
	actor_body->setMaterial(actor_material);
	actor_material->setFriction(terrain_material, 0, 0);
	actor_material->setCollidable(terrain_material, true);

	//terrain triangle selector, used for camera
	scene::ITriangleSelector* selector = 0; 	
	selector = smgr->createTerrainTriangleSelector(terrain, 0); 
	terrain->setTriangleSelector(selector);
	selector->drop();

	scene::ISceneNodeAnimator * anim = smgr->createCollisionResponseAnimator( selector, actor, core::vector3df(10,24.5,10),	core::vector3df(0,-9.81,0), core::vector3df(0,-0.1,0));
	actor->addAnimator(anim);
	anim->drop();

	//camera RPG (test)
	irr::scene::CCameraRPGSceneNode* camera = new irr::scene::CCameraRPGSceneNode(actor, smgr, 1, device, selector); 
	camera->configure("cam.xml");
	smgr->setActiveCamera(camera);
    camera->drop();

and i can't bind the camera to actor_body ...

any help is appreciated.

now i can go to sleep

Is it possible to re-write this camera so that it inherits from CCameraSceneNode instead of having to copy it from irrlicht source folder every time a new version of irrlicht comes out?

I've tried a couple of time and failed. I may try again with v1.5 of irrlicht.

That can seems to live longer than I expected !

Well, I would like to update the first post of this thread with the link of the current source code of this camera. Anybody has a link of can someone can seend me the cam files ?

Xter.

Huh? Are you asking for someone to send you a link to the old camera files? Don't you still have it?

Anyway, I tried with 1.5 irrlicht and failed (trying to make it inherit instead of copying CCameraSceneNode).

Hey, cool. If you use opera 10 alpha, it underlines your typos for you.

Update:

ssexton posted the whole source a page or so back.

The suggested way of creating a new camera for Irrlicht 1.5 is to make a new camera animator!

Hmmm...I'll look into it, thanks hybrid. Camera and animator doesn't seem like it should be in the same sentence.

Anyway, would some mod move this to the 'project announcement' thread? xterminhate posted in the wrong forum and it's been stuck here since.

If I can get a 'new camera animator' version working, I'll post it here for everyone to use. But it might take some time. I probably end up butchering it to pieces then it won't build or nothing any more.

I'll move it to code snippets

Thanks, hybrid!
