--DESCRIPTION: calculates total distance travelled by player
--DESCRIPTION: [@Mode=1(1=Total_Distance,2=From_Start)] changes between any movement adding to the total movement
--DESCRIPTION: or only calculating how far the player moves away from the starting location
--DESCRIPTION: [IgnoreY!=0] will allow you to ignore altitude changes and jumping etc
--DESCRIPTION: which is handy for a flat map or where you only care about the birds-eye distance
