Function TargetBox

* @brief Sets a box as the creature's navigation target. * * Generates a random position within the box boundaries as the target point. * This randomization prevents creatures from always going to the exact same * spot, making movement look more natural. * * Sets LOT->RequiredBox which triggers UpdateLOT to recalculate the path. * * @param LOT Pointer to the creature's LOTInfo. * @param b

 * @param boxNumber The box to target.
