Delete les blocks que j'ai fais spawn avec mon skript

[AISsBenji]

Bonjour, dans mon skript :

on rightclick with packed ice:
   if name of player's tool is "&b&lCage de Glace":
       set {_wait} to difference between {killer.%player%.lastused} and now
   if {_wait} is less than {@cooldown}:
       message "&d[&7IriEffect&d]&7 Vous devez attendre 12 secondes"
   else:
       if targeted entity is a player:
           message "&d[&7IriEffect&d]&7 Vous avez créer une cage de glace"
           apply slowness 1000 to targeted player for 5 seconds
           set {_loc} to location of targeted player
           add 2 to y-coordinate of {_loc}
           loop blocks in radius {@radius-max} of location of {_loc}:
               if loop-block is air:
                   set loop-block to packed ice
           loop blocks in radius {@radius-min} of location of {_loc}:
               if loop-block is packed ice:
                   set loop-block to air
           set {killer.%player%.lastused} to now
           stop
       else:
           message "&d[&7IriEffect&d]&7 Aucun joueur ciblé" to player
           stop

J'aimerais supprimer après 5 secondes les blocks du :

set {_loc} to location of targeted player
           add 2 to y-coordinate of {_loc}
           loop blocks in radius {@radius-max} of location of {_loc}:
               if loop-block is air:
                   set loop-block to packed ice
           loop blocks in radius {@radius-min} of location of {_loc}:
               if loop-block is packed ice:
                   set loop-block to air

Merci d'avance. (oui c'est la troisième fois en 3 jours que je demande de l'aide mais je suis amateur, vous moquer pas (:)
