Python: move_to in dungeons e.g. fgw

Hey,

Update:
Sorry, I already figured it out myself…
I just need to use the last 3 values. But now I still have the question, what the first parameter is used for (e.g. -32750).

got a question about the move_to python function:
It takes 3 parameters for walking: x,y,z
If I take a look at recorded walking scripts in FGW, they have 4 parameters.
E.g.:
walk,-32750,-20097,-547,169
Anyone knows how I can convert the values from the recorded FGW scripts to work with the move_to method?

move_to_region(region, x, y, z)
