Workspace.Shedletsky.Humanoid:MoveTo(Vector3.new(0,0,0))
The above line allows the character of "Shedletsky" to walk to the position, since the MoveTo method is used onto the Humanoid, not the character. The position is a Vector3 value.
Workspace.Shedletsky.Humanoid:MoveTo(Workspace.Part)
This line is the same thing as the first, except that a Part is used as the argument instead of the Vector3 value. 'Shedletsky' will walk to the Part named.
Workspace.Shedletsky:MoveTo(Vector3.new(0,0,0))
This snip-it of code (above) looks similar to the first example but is different. Because you are using the MoveTo method to the character, not the Humanoid of that character, this line would teleport 'Shedletsky' to the position (which is a Vector3 value).
