I fixed it! it was just little mistake. here's fixed code :

Code:

void CVehiclePlayer::Update(float fTimeElapsed, btDiscreteDynamicsWorld* pbtDynamicsWorld, DWORD dwBehave){switch (dwBehave){case DIR_LEFT:{m_gVehicleSteering += m_steeringIncrement * fTimeElapsed;if (m_gVehicleSteering > m_steeringClamp)m_gVehicleSteering = m_steeringClamp;for (int i = 0; i < 2; ++i){m_pWheel[i]->getHinge()->setTargetVelocity(5, m_gVehicleSteering);}break;}case DIR_RIGHT:{m_gVehicleSteering -= m_steeringIncrement * fTimeElapsed;if (m_gVehicleSteering < -m_steeringClamp)m_gVehicleSteering = -m_steeringClamp;for (int i = 0; i < 2; ++i){m_pWheel[i]->getHinge()->setTargetVelocity(5, m_gVehicleSteering);}break;}case DIR_FORWARD:{m_gEngineForce += m_EngineForceIncrement * fTimeElapsed;m_gBreakingForce = 0.f;for (int i = 0; i < 2; ++i){m_pWheel[i]->getHinge()->setTargetVelocity(3, m_gEngineForce);}break;}case DIR_BACKWARD:{m_gEngineForce -= m_EngineForceIncrement * fTimeElapsed;m_gBreakingForce = 0.f;for (int i = 0; i < 2; ++i){m_pWheel[i]->getHinge()->setTargetVelocity(3, m_gEngineForce);}break;}}}

How can I control Throttle and Steering of Hinge2Vehicle?

2021-07-18T04:42:28+00:00

first, sorry for bad english

I follow some example about Hinge2Vehicle, than I realized that Hinge2Vehicle doesn't have any Control of Throttle
So I guess that pHinge2->setTargetVelocity is might be solution of this, and this is result

Code:

switch (dwBehave){case DIR_LEFT:{m_gVehicleSteering += m_steeringIncrement;if (m_gVehicleSteering > m_steeringClamp)m_gVehicleSteering = m_steeringClamp;for (int i = 0; i < 2; ++i){m_pWheel[i]->getHinge()->setTargetVelocity(5, m_gVehicleSteering);}break;}case DIR_RIGHT:{m_gVehicleSteering -= m_steeringIncrement;if (m_gVehicleSteering < -m_steeringClamp)m_gVehicleSteering = -m_steeringClamp;for (int i = 0; i < 2; ++i){m_pWheel[i]->getHinge()->setTargetVelocity(5, m_gVehicleSteering);}break;}case DIR_FORWARD:{m_gEngineForce = m_maxEngineForce;m_gBreakingForce = 0.f;for (int i = 0; i < 2; ++i){m_pWheel[i]->getHinge()->setTargetVelocity(3, m_gEngineForce);}break;}case DIR_BACKWARD:{m_gEngineForce = -m_maxEngineForce;m_gBreakingForce = 0.f;for (int i = 0; i < 2; ++i){m_pWheel[i]->getHinge()->setTargetVelocity(3, m_gEngineForce);}break;}}

but result is very wrong - wheels are not rotates it self, but it revolution with pBodyA - chassis of the car
how can i fix this? i can't find what is wrong
