 You can do the same with the ground by replacing OBJECT_FLAG.WATER by OBJECT_FLAG.GROUND
-If the water (or the ground) is not found (for instance when the _globalPosition out of the map) then a warning is edited in the logs, and the code return the Y of the _globalPosition.
+If the water (or the ground) is not found (for instance when the ''_globalPosition'' out of the map) then a warning is edited in the logs, and the code returns the Y of the ''_globalPosition''.
+This can be used, for instance, when moving an object on the ground or water whatever the slope (the water HAVEN'T the same elevation anywhere on a vanilla map !).
