"Gravity" in the terrain example?

[NexusInteractive]

Hello. I'm using the terrain example to try out different things for irrlicht and stuff, but I don't like how the camera just "flys" around. I would like the player to stay on the ground instead of going wherever the cursor points.

I'm really new to Irrlicht, so could you please explain where the codes go in the example and such?

Thanks!

check out the quake3 map example (i think its example 3) at the tutorials..it is used there too.

I'm really new to Irrlicht and C++ so i have no idea what does what in that code... (and i think it's tut #6 that has the gravity)

try something like this:

Code: Select all

// set the camera scenenode...
scene::ICameraSceneNode* camera;

camera = smgr->addCameraSceneNodeFPS(0,100.0f,300.0f);
camera->setPosition(core::vector3df(10,100,10));


// load the "gravity"-animator...
scene::ISceneNodeAnimator* animator = smgr->createCollisionResponseAnimator(
		selector, camera, core::vector3df(30,50,30),
		core::vector3df(0,-100,0), // 100.0f, 
		core::vector3df(0,50,0));

camera->addAnimator(animator); // <- gravity (!!)
animator->drop();

hope that helps..

Well, I tried and nothing happens. I don't get any errors and there isn't any gravity... Here's what I have:

Code: Select all

// add camera
	scene::ICameraSceneNode* camera = 
		smgr->addCameraSceneNodeFPS(0,100.0f,1200.0f);

	camera->setPosition(core::vector3df(1900*2,255*2,3700*2));
	camera->setTarget(core::vector3df(2397*2,343*2,2700*2));
	camera->setFarValue(12000.0f);

	// load the "gravity"-animator...
	scene::ISceneNodeAnimator* animator = smgr->createCollisionResponseAnimator(
      selector, camera, core::vector3df(30,50,30),
      core::vector3df(0,-100,0), // 100.0f,
      core::vector3df(0,50,0));

      camera->addAnimator(animator); // <- gravity (!!)
      animator->drop();

Any ideas?

Okay, I put it in the wrong place. It works okay now. I also had to change core::vector3df(0,50,0)); to core::vector3df(0,100,0)); becuase the camera kept bouncing up and down. But now, when I go up a hill, the camera bounces slightly and i slide back down. Would it be possible to make it not do that?
