 *
 * <p>If an intersection with any block or entity was found, a RaytraceResult representing the intersection
 * that is closest to {@code startLocation} will be returned. If no such intersection was found, this
 * method will return null.</p>
 *
 * <p>Entities included in {@code entitiesToExclude} and dropped item entities will be ignored by
 * the raytrace.</p>
 *
 * @param startLocation The location from which the raytrace will start
 * @param vector The direction and maximum distance of the raytrace
 * @param entitiesToExclude An array of entities that will be ignored by this raytrace, may contain null
 * @return A RaytraceResult for the nearest intersection, or null if no intersection was found
