What is wrong with this collision?

[Sidus]

My objective is to make collide my character on a huge heightmap.
It seems works pretty nice when a zone is flat as in this pic:



But it seems to fly over the terrain if a ground down:



How do i fix it?

Here's my code:

Terrain

Code: Select all

// Create Island
	scene::ITerrainSceneNode* terrain = smgr->addTerrainSceneNode(
    "media/models/heightmaps/island_HM.jpg",
    0,					// parent node
    -1,					// node id
    core::vector3df(-6000.f, -2703.f, -3000.f),	// position
    core::vector3df(0.f, 0.f, 0.f),		// rotation
    core::vector3df(10.f, 15.f, 10.f),	// scale 10,7,10
    video::SColor ( 255, 255, 255, 255 ),	// vertexColor
    4,					// maxLOD
    scene::ETPS_17,		// patchSize
    4					// smoothFactor
    );

	terrain->setMaterialTexture(0,
    driver->getTexture("media/models/heightmaps/island_TX.jpg"));
	terrain->setMaterialTexture(1,
    driver->getTexture("media/data/detail5.bmp"));
	terrain->setMaterialType(video::EMT_DETAIL_MAP);
    terrain->scaleTexture(1.0f, 5000.0f);
    terrain->setMaterialFlag(video::EMF_FOG_ENABLE, true);
    terrain->setMaterialFlag(video::EMF_LIGHTING, false);
    terrain->getMesh()->setHardwareMappingHint(EHM_STATIC);

	scene::CDynamicMeshBuffer* buffer =
	new scene::CDynamicMeshBuffer(video::EVT_2TCOORDS, video::EIT_32BIT);
	terrain->getMeshBufferForLOD(*buffer, 0);
	video::S3DVertex2TCoords* data = (video::S3DVertex2TCoords*)
	buffer->getVertexBuffer().getData();
	buffer->drop();

Player

Code: Select all

	IAnimatedMesh* dmesh = smgr->getMesh("media/models/md2/player.md2");
	if (!dmesh)
	{
		device->drop();
		return 1;
	}
	IAnimatedMeshSceneNode* dnode = smgr->addAnimatedMeshSceneNode( dmesh );

	if (dnode)
	{
		dnode->setMaterialFlag(EMF_LIGHTING, true);
		dnode->setMaterialFlag(video::EMF_FOG_ENABLE, true);
		dnode->setMD2Animation(scene::EMAT_STAND);
		dnode->setAnimationSpeed(15);
		dnode->setMaterialTexture( 0,
        driver->getTexture("media/models/md2/player.jpg"));
		dnode->setPosition(vector3df(-2445,150,5140));
		dnode->setScale(vector3df(0.01,0.01,0.01));
		dnode->setRotation(vector3df(0,90,0));
	}

Selector

Code: Select all

	// Create Triangle Selector for the terrain
	scene::ITriangleSelector* selector
    = smgr->createTerrainTriangleSelector(terrain, 0);
	terrain->setTriangleSelector(selector);

    // Meta Triangle Selector
    scene::IMetaTriangleSelector* metaSelector = smgr->createMetaTriangleSelector();
    metaSelector->addTriangleSelector(selector);

    // Collision
    ISceneNodeAnimatorCollisionResponse* anim1;
    anim1 = smgr->createCollisionResponseAnimator(
    metaSelector, dnode, core::vector3df(25,50,25),
    core::vector3df(0, terrain ? -2.5 : 0.0,0),
    core::vector3df(0,-49.78,0), 0.005f);
    dnode->addAnimator(anim1);
    anim1->drop();

Resolved
had to increase these values:

Code: Select all

   ***metaSelector, dnode, core::vector3df(25,5000,25),
    core::vector3df(0, terrain ? -2.5 : 0.0,0),
    core::vector3df(0,-4999.78,0), 0.005f);***
