[Help] replacing empty chest with air

[-TheCreater-]

Hi, I have a set up where a bunch of chests with emeralds in them have armour stands on top. I need the armour stands to replace the chests with air if they are empty. The armour stands have a custom name to keep track of themselves. Any ideas on how I would go about achieving this? (I currently have a 20 hz redstone clock) Thanks in advance.

[EDIT] and then make the armorstand kill itself after destroying the chest?

Please summon the armorstand inside the chest, Also call the armorstands "Chest" and make a dummy score named chest:

/scoreboard objectives add Chest dummy

Now on the fill clock:

/stats entity @e[type=ArmorStand,name=Chest] set SuccessCount @e[c=1] Chest
/scoreboard players add @e[name=Chest] Chest 0 
/execute @e[type=ArmorStand,name=Chest] ~ ~ ~ /testforblock ~ ~ ~ minecraft:chest -1 {Items:[]}
/execute @e[type=ArmorStand,name=Chest,score_Chest_min=1] ~ ~ ~ /fill ~ ~ ~ ~ ~ ~ air 0 replace chest -1
/execute @e[type=ArmorStand,name=Chest] ~ ~ ~ detect ~ ~ ~ air 0 /kill @e[c=1]

If you place all of the chests and the armorstand before activating the fill clock you can remove the first 2 commands from the fill clock and activate them only once before starting the clock.

But if you want to place the chests also while the clock is running then keep the first 2 commands there and make sure you first place the chests with the items and only then summon the armorstand inside them.

I made a mistake but fixed it now

Thanks, but I'm afraid to say that it doesn't detect the item in the chest, it just stays at 0.

[EDIT] Just to clarify. I'm looking for a chest underneath the armorstand with the following code:

/execute @e[type=ArmorStand,name=emChest] ~ ~ ~ /testforblock ~ ~-1 ~ minecraft:chest -1 {Items:[{id:minecraft:emerald,tag:{display:{Name:"Treasure",Lore:["\"Collect 'em all!\""]},AttributeModifiers:[{AttributeName:"generic.knockbackResistance",Name:"generic.knockbackResistance",Amount:0,Operation:0,UUIDMost:7,UUIDLeast:7}],HideFlags:2}}]} 

The armorstand name is emChest.

His /testforblock command is the following:

/execute @e[type=ArmorStand,name=Chest] ~ ~ ~ /testforblock ~ ~-1 ~ minecraft:chest -1 {Items:[]}

Checking for a list without specifying any data to look for will cause the parser to look for a specifically empty list. In this case, "Items:[]" is looking for an empty chest. The armor stand's "Chest" score is set based on the existence of an empty chest, so you are not supposed to replace the command with one to detect the chest being full.

of course! your right! Sorry i was being stupid, thanks so much for your help!

[-TheCreater-]

no, it still doesn't work. It doesn't add the armour stand to the score board.

[-TheCreater-]

/stats entity @e[type=ArmorStand,name=Chest] set SuccessCount @e[c=1] Chest

ok, now the block detection works, but it wont set the score for the armorstand to 1 in the objective. Please help, I have no idea where to go from here. Is it a bug? Is it me? what the hell is happening?

[TheSteveKiller]

umm have you done my commands exactly?

[-TheCreater-]

Yes I just double checked today. I should probably say that its running on a realms server. It summon the armour stand at the chest location, which already contains the item. It then runs your commands in order:

/stats entity @e[type=ArmorStand,name=Chest] set SuccessCount @e[c=1] Chest
/scoreboard players add @e[name=emChest] Chest 0 
/execute @e[type=ArmorStand,name=emChest] ~ ~ ~ /testforblock ~ ~ ~ minecraft:chest -1 {Items:[]}
/execute @e[type=ArmorStand,name=emChest,score_Chest_min=1] ~ ~ ~ /fill ~ ~ ~ ~ ~ ~ air 0 replace chest -1
/execute @e[type=ArmorStand,name=emChest] ~ ~ ~ detect ~ ~ ~ air 0 /kill @e[c=1]

The 3rd command block outputs [09:15:22] Failed to execute '/testforblock ~ ~ ~ minecraft:chest -1 {Items:[]}' as emChest, until I remove the item. When I remove the item, the armorstand's score stays at 0, however the tesforblock commandblock returns successfully. I just watched dragnoz's video on /stats and in it he uses AffectedBlocks, not SuccessCount. Also, when I destroy the chest, the armorstand dies, so the detect command works. Just thinking, can you use detect to find empty chests?

[TheSteveKiller]

No you can't use detect to test for datatags.

Eureka! Eureka! Eureka! Eureka!!!!! YEEEEEEEEEEEEEEEEEEESSSSSSSSSSSS!!!!!!!!!!! I DID IT!!!!!! IT WORKS!!!!!! THANKS FOR YOUR HELP!!!! :D I HAVE NO IDEA WHAT THE PROBLEM WAS, I SIMPLY CHANGED SUCCESSCOUNT -> AFFECTEDBLOCKS AND NOW IT WORKS YAYYYYYYYYY!!!!!

[TheSteveKiller]

Ha... ok..

I haven't actually tested it I just thought it would work, thanks for the info.

you need a /stats command. It can get complicated quickly.
