the class RayTraceFactory method rayTrace.

/**
 * Performs the SmartRaytrace.
 * A res value of >= 1.0 means that just the middle
 * of the block will be traced, a value <= 0 means
 * that the 4 corners and the middle will be traced
 * and other values set the step width for many raytraces.
 * A value of -1.0 is recommended.
 *
 * @param from the entity from whose eyes to trace.
 * @param on the position to trace to.
 * @param facing the offset to the position.
 * @param access BlockAccess
 * @param state the state at the position
 * @param res the resolution as explained above
 * @return a Ray, never null.
