| PxReal | contactDistance |

Construct a linear hard limit pair. The lower distance value must be less than the upper distance value.
| [in] | scale | A PxTolerancesScale struct. Should be the same as used when creating the PxPhysics object. |
| [in] | lowerLimit | The lower distance of the limit |
| [in] | upperLimit | The upper distance of the limit |
| [in] | contactDist | The 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) |
