sauvegarder un coffre

[grod0026]

Bonjour, j"ai un petit soucis et je l'avoue je ne comprends pas

command /sauvcof:
   trigger:
       if {sauvcof} is false:
           set {sauvcof} to true
           send "sauvegarde des coffres demarre"
       else:
           set {sauvcof} to false
           send "sauvegarde des coffres arrete"
           send "RESTAURATION DES %size of {Chest.location::*}% COFFRES"
           loop {Chest.location::*}:
               send "coffre en %loop-value%"
               set {_pos} to loop-value
               loop {Chest.item.%loop-value%::*}:
                   loop integers between 0 and 26:
                       set {_item} to loop-value
                       send "item : %{_item}%"
                       add {_item} to slot loop-integer of block at {_pos}
           clear {Chest.location::*}


on rightclick on a chest:
   {sauvcof} is true:
       send "nombres de coffres en surveillances : %size of {Chest.location::*}%"
       set {trouve} to 0
       loop {Chest.location::*}:
           if loop-value is location of targeted block:
               send "coffre deja enregistre"
               set {trouve} to 1
       if {trouve} is 0:
           add location of targeted block to {Chest.location::*}
           send "coffre non enregistre"          
           clear {Chest.item.%location of targeted block%::*}
           send "-------  contenu du coffre : -------"
           loop integers between 0 and 26:
               set {_contient} to slot loop-integer of block at location at targeted block
               if {_contient} is not air:
                   send "emplacement %loop-value-1% contient %{_contient}%"
               # add {_contient} to {Chest.item.%loop-value%::*}
               set {_index} to location of targeted block
               add {_contient} to {Chest.item.%{_index}%::*}

j'arrive bien a 'voir' le contenu du coffre mais pas a le restaurer quelqu'un a une idée ?

merci

ps je pense que je bafouille avec les listes ++
