| − | + | This routine searches for a new destination for a unit around its point of origin. | |

| − | + | This routine set Targetable grid (0x80192dd8) byte 0x02 to 0x01 if There is a unit on the panel | |
| − | + | ----------------------------------------------------------------- | |

| − | + | Returns r2 = 0x00 if Tile to relocated is found and set | |

This routine searches for a new destination for a unit around its point of origin.
(For example to relocate the body of a dead rider around is chocobo)
This routine set Targetable grid (0x80192dd8) byte 0x02 to 0x01 if There is a unit on the panel
-----------------------------------------------------------------
Parameters r4 = Unit Raw ID (Unit data 0x18a)
Returns r2 = 0x00 if Tile to relocated is found and set
r2 = -0x01 if No destination has been found
----------------------------------------------------------------

Notes
The word at 0x8019f4f4 seems to be the counter of relocated unit (waiting for something i guess since it's reseted after the next action) The Table at 0x80193880 store the coordinates of this relocated units. 0x00 is X coordinates 0x01 is Y coordinates 0x02 is Elevation
