我目前正在尝试向我的LWJGL引擎添加物理学。 我使用JBullet库。 一切正常，可以与其他对象碰撞并反弹，但不会旋转。我进行了很多搜索，但找不到任何解决方案。 这是我的代码片段：
public void initPhysics() {
broadphase = new DbvtBroadphase();
collisionConfiguration = new DefaultCollisionConfiguration();
dispatcher = new CollisionDispatcher(collisionConfiguration);
solver = new SequentialImpulseConstraintSolver();
dynamicsWorld = new DiscreteDynamicsWorld(dispatcher, broadphase, solver, collisionConfiguration);
dynamicsWorld.setGravity(new Vector3f(0, -50, 0));
CollisionShape groundShape = new StaticPlaneShape(new Vector3f(0, 1, 0), 1);
DefaultMotionState groundMotionState = new DefaultMotionState(new Transform(new Matrix4f(new Quat4f(0, 0, 0, 1), new Vector3f(0, -1, 0), 1.0f)));
groundShape.calculateLocalInertia(0, new Vector3f(0,0,0));
Vector3f groundInertia = new Vector3f(0f, 0f, 0f);
RigidBodyConstructionInfo groundRigidBodyCI = new RigidBodyConstructionInfo(0, groundMotionState, groundShape, groundInertia);
groundRigidBodyCI.restitution = .25f;
groundRigidBody = new RigidBody(groundRigidBodyCI);
dynamicsWorld.addRigidBody(groundRigidBody);
rigidBodies.add(groundRigidBody);
CollisionShape fallShape = new BoxShape(new Vector3f(3,3,3));
DefaultMotionState fallMotionState = new DefaultMotionState(new Transform(new Matrix4f(new Quat4f(0, 0, 0, 1), new Vector3f(-830, 50,-80), 1.0f)));
Vector3f fallShapeInertia = new Vector3f(0f, 0f, 0f);
fallShape.calculateLocalInertia(1, fallShapeInertia); // mass ve inertia
RigidBodyConstructionInfo fallRigidBodyCI = new RigidBodyConstructionInfo(1, fallMotionState, fallShape, fallShapeInertia);
fallRigidBodyCI.restitution = .25f;
fallRigidBody = new RigidBody(fallRigidBodyCI);
dynamicsWorld.addRigidBody(fallRigidBody);
rigidBodies.add(fallRigidBody);
CollisionShape fallShape2 = new BoxShape(new Vector3f(3,3,3));
DefaultMotionState fallMotionState2 = new DefaultMotionState(new Transform(new Matrix4f(new Quat4f(0, 0, 0, 1), new Vector3f(-834, 70,-80), 1.0f)));
Vector3f fallShape2Inertia = new Vector3f(0f, 0f, 0f);
fallShape2.calculateLocalInertia(1, fallShape2Inertia); // mass ve inertia
RigidBodyConstructionInfo fallRigidBodyCI2 = new RigidBodyConstructionInfo(1, fallMotionState2, fallShape2, fallShape2Inertia);
fallRigidBodyCI2.restitution = .25f;
fallRigidBody2 = new RigidBody(fallRigidBodyCI2);
dynamicsWorld.addRigidBody(fallRigidBody2);
rigidBodies.add(fallRigidBody2);
CollisionShape player = new BoxShape(new Vector3f(3,3,3));
DefaultMotionState playerMotionState = new DefaultMotionState(new Transform(new Matrix4f(new Quat4f(0, 0, 0, 1), new Vector3f(-834, 0, -60), 1.0f)));
Vector3f playerShapeInertia = new Vector3f(0f, 0f, 0f);
player.calculateLocalInertia(1, playerShapeInertia); // mass ve inertia
RigidBodyConstructionInfo playerRigidBodyCI = new RigidBodyConstructionInfo(1, playerMotionState, player, playerShapeInertia);
playerRigidBodyCI.restitution = .25f;
playerRigidBody = new RigidBody(playerRigidBodyCI);
dynamicsWorld.addRigidBody(playerRigidBody);
rigidBodies.add(playerRigidBody);
System.out.println("Fizik objeleri: " + dynamicsWorld.getNumCollisionObjects()); // addObject fonksiyonu saymıyor!
}
public void addObject(Entity entity)
{
Quat4f outRot = new Quat4f();
Vector3f entityPosition = fallRigidBody.getWorldTransform(new Transform()).origin;
Quat4f entityRotation = fallRigidBody.getWorldTransform(new Transform()).getRotation(outRot);
entityRotation.w = 1;
entity.setPositionn(entityPosition.x, entityPosition.y, entityPosition.z);
entity.setRotation (entityRotation.x, entityRotation.y, entityRotation.z);
}
public void addObject2(Entity entity)
{
Quat4f outRot = new Quat4f();
Vector3f entityPosition = fallRigidBody2.getWorldTransform(new Transform()).origin;
Quat4f entityRotation = fallRigidBody2.getWorldTransform(new Transform()).getRotation(outRot);
entityRotation.w = 1;
entity.setPositionn(entityPosition.x, entityPosition.y, entityPosition.z);
entity.setRotation (entityRotation.x, entityRotation.y, entityRotation.z);
}
public void addPlayerObject(Entity entity)
{
Vector3f playerPosition = playerRigidBody.getWorldTransform(new Transform()).origin;
playerPosition.x = entity.getPosition().x;
playerPosition.y = entity.getPosition().y;
playerPosition.z = entity.getPosition().z;
}
public void updatePhysics()
{
dynamicsWorld.stepSimulation(1/60.f, 10);
}
public void cleanUpPhysics()
{
rigidBodies.clear();
}
顺便说一句，我的addPlayerObject（）函数不起作用... 我仍然可以像鬼一样穿过物理对象。有什么问题？
