Public Attributes | |
| Vec3 | mPosition { 0, 0, 0 } |
| Attachment point of wheel suspension in local space of the body. | |
| Vec3 | mSuspensionDirection { 0, -1, 0 } |
| Direction of the suspension in local space of the body, should point down. | |
| Vec3 | mSteeringAxis { 0, 1, 0 } |
| Direction of the steering axis in local space of the body, should point up (e.g. for a bike would be -mSuspensionDirection) | |
| Vec3 | mWheelUp { 0, 1, 0 } |
| Up direction when the wheel is in the neutral steering position (usually VehicleConstraintSettings::mUp but can be used to give the wheel camber or for a bike would be -mSuspensionDirection) | |
| Vec3 | mWheelForward { 0, 0, 1 } |
| Forward direction when the wheel is in the neutral steering position (usually VehicleConstraintSettings::mForward but can be used to give the wheel toe, does not need to be perpendicular to mWheelUp) | |
| float | mSuspensionMinLength = 0.3f |
| How long the suspension is in max raised position relative to the attachment point (m) | |
| float | mSuspensionMaxLength = 0.5f |
| How long the suspension is in max droop position relative to the attachment point (m) | |
| float | mSuspensionPreloadLength = 0.0f |
| The natural length (m) of the suspension spring is defined as mSuspensionMaxLength + mSuspensionPreloadLength. Can be used to preload the suspension as the spring is compressed by mSuspensionPreloadLength when the suspension is in max droop position. Note that this means when the vehicle touches the ground there is a discontinuity so it will also make the vehicle more bouncy as we're updating with discrete time steps. | |
| float | mSuspensionFrequency = 1.5f |
| Natural frequency of the suspension spring (Hz) | |
| float | mSuspensionDamping = 0.5f |
| Damping factor of the suspension spring (0 = no damping, 1 = critical damping) | |
| float | mRadius = 0.3f |
| Radius of the wheel (m) | |
| float | mWidth = 0.1f |
| Width of the wheel (m) | |
