- Public Attributes inherited from WheelSettings
Vec3 mPosition { 0, 0, 0 }
 Attachment point of wheel suspension in local space of the body. More...
 
Vec3 mSuspensionForcePoint { 0, 0, 0 }
 Where tire forces (suspension and traction) are applied, in local space of the body. A good default is the center of the wheel in its neutral pose. See mEnableSuspensionForcePoint. More...
 
Vec3 mSuspensionDirection { 0, -1, 0 }
 Direction of the suspension in local space of the body, should point down. More...
 
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) More...
 
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) More...
 
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) More...
 
float mSuspensionMinLength = 0.3f
 How long the suspension is in max raised position relative to the attachment point (m) More...
 
float mSuspensionMaxLength = 0.5f
 How long the suspension is in max droop position relative to the attachment point (m) More...
 
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. More...
 
SpringSettings mSuspensionSpring { ESpringMode::FrequencyAndDamping, 1.5f, 0.5f }
 Settings for the suspension spring. More...
 
float mRadius = 0.3f
 Radius of the wheel (m) More...
 
float mWidth = 0.1f
 Width of the wheel (m) More...
 
bool mEnableSuspensionForcePoint = false
 Enables mSuspensionForcePoint, if disabled, the forces are applied at the collision contact point. This leads to a more accurate simulation when interacting with dynamic objects but makes the vehicle less stable. When setting this to true, all forces will be applied to a fixed point on the vehicle body. More...
