public float getCcdSquareMotionThreshold() {
        return rBody.getCcdSquareMotionThreshold();
    }
Sets the amount of motion that has to happen in one physics tick to trigger the continuous motion detection<br>
This avoids the problem of fast objects moving through other objects, set to zero to disable (default)

@param threshold the desired minimum distance per timestep to trigger CCD
(in physics-space units, &gt;0) or zero to disable CCD (default=0)
