[EXPLANATION]
xpos = the X position of the co-ordinates of the interior
ypos = the Y position of the co-ordinates of the interior
zpos = the Z position of the co-ordinates of the interior
int = the interior of the co-ordinates
[---------------------------------------------------------]
the explanation is just to show u... you have to put the co-ordinates of the interior u want there..
replace zpos,xpos,ypos and int with the co-ords as said..
use this on a command or pickup
SetPlayerInterior(playerid,int);
SetPlayerPos(playerid,xpos,ypos,zpos);
quite simple...
