Detailed Description

Describes a two-sided limit.

Constructor & Destructor Documentation

PxJointLinearLimitPair::PxJointLinearLimitPair ( const PxTolerancesScale scale,
PxReal  lowerLimit,
PxReal  upperLimit,
PxReal  contactDist = -1 
)
inline

Construct a linear hard limit pair. The lower distance value must be less than the upper distance value.

Parameters
[in]scalea PxTolerancesScale struct. Should be the same as used when creating the PxPhysics object.
[in]lowerLimitthe lower distance of the limit
[in]upperLimitthe upper distance of the limit
[in]contactDistthe distance from the limit at which it becomes active. Default is the lesser of 0.01f scaled by the tolerance length scale, and 0.49 * (upperLimit - lowerLimit)
