@ Pip : To complete the command PlaceObject, I looked the commands associated with tiles and I found this command:

//returns the ID of a given pairing of set/tile. -1 means the tile doesn't exist. These are the internal folder/tile names, not the displayed localised names. NOTE: this will not be a constant as game data and custom data changes, so don't rely on it.
GetTileID(set, name)

I understand that it is not displayed localised names. So, where i can find this set/name ? At last, if possible

In the meantime I found an other way to work with tiles:
- I place on precise coordinates the tiles that interest me (offmap).
- And I use in scripts and functions GetTileOnTile and PlaceTile to generate by copying and pasting what I need.

I get to build roads and rivers with a script A first step in creating random maps

The tile names are found in the TILES.TXT file in each folder, and the set name is in fact the folder name.

Like your clever approach - although you can do the same kind of thing using the names, but whatever works best for you

Great thanks

Refer to the text is probably more practical.
