| value | Base half-life in seconds. Default is 0.25. |
Sets the base half-life for the heuristic per-axis decay constant calculation.
The half-life h for each axis is computed as: h = Clamp(halfLifeBase * D / V, halfLifeMin, halfLifeMax), where D is the distance to target and V is the velocity. The decay constant c is then ln(2) / h. A larger half-life produces slower convergence.
