How do you stop OgreBullet Capsule from falling over?
- by Nathan Baggs
I've just started implementing bullet into my Ogre project. I followed the install instructions here: http://www.ogre3d.org/tikiwiki/OgreBullet+Tutorial+1
And the rest if the tutorial here:
http://www.ogre3d.org/tikiwiki/OgreBullet+Tutorial+2
I got that to work fine however now I wanted to extend it to a handle a first person camera. I created a CapsuleShape and a Rigid Body (like the tutorial did for the boxes) however when I run the game the capsule falls over and rolls around on the floor, causing the camera swing wildly around.
I need a way to fix the capsule to always stay upright, but I have no idea how
Below is the code I'm using.
(part of) Header File
OgreBulletDynamics::DynamicsWorld *mWorld; // OgreBullet World
OgreBulletCollisions::DebugDrawer *debugDrawer;
std::deque<OgreBulletDynamics::RigidBody *> mBodies;
std::deque<OgreBulletCollisions::CollisionShape *> mShapes;
OgreBulletCollisions::CollisionShape *character;
OgreBulletDynamics::RigidBody *characterBody;
Ogre::SceneNode *charNode;
Ogre::Camera* mCamera;
Ogre::SceneManager* mSceneMgr;
Ogre::RenderWindow* mWindow;
main file
bool MinimalOgre::go(void)
{
...
mCamera = mSceneMgr->createCamera("PlayerCam");
mCamera->setPosition(Vector3(0,0,0));
mCamera->lookAt(Vector3(0,0,300));
mCamera->setNearClipDistance(5);
mCameraMan = new OgreBites::SdkCameraMan(mCamera);
OgreBulletCollisions::CollisionShape *Shape;
Shape = new OgreBulletCollisions::StaticPlaneCollisionShape(Vector3(0,1,0), 0); // (normal vector, distance)
OgreBulletDynamics::RigidBody *defaultPlaneBody = new OgreBulletDynamics::RigidBody(
"BasePlane",
mWorld);
defaultPlaneBody->setStaticShape(Shape, 0.1, 0.8); // (shape, restitution, friction)
// push the created objects to the deques
mShapes.push_back(Shape);
mBodies.push_back(defaultPlaneBody);
character = new OgreBulletCollisions::CapsuleCollisionShape(1.0f, 1.0f, Vector3(0, 1, 0));
charNode = mSceneMgr->getRootSceneNode()->createChildSceneNode();
charNode->attachObject(mCamera);
charNode->setPosition(mCamera->getPosition());
characterBody = new OgreBulletDynamics::RigidBody("character", mWorld);
characterBody->setShape( charNode,
character,
0.0f, // dynamic body restitution
10.0f, // dynamic body friction
10.0f, // dynamic bodymass
Vector3(0,0,0),
Quaternion(0, 0, 1, 0));
mShapes.push_back(character);
mBodies.push_back(characterBody);
...
}
