Minecraft redstone signal from a locked trap chest

minecraft-commandsminecraft-java-editionminecraft-redstone

I know that when you open a trapped chest, it generates a small redstone signal. So I locked the chest with /blockdata ~ ~-1 ~ {Lock:"Name of chest"}, but when I right click, it doesn't generate a redstone signal. I know this is quite obvious, but I wanted to make a system where if you try and open a trapped chest, it would trigger a command block.

How can I do this?

Are you sure no redstone signal is generated? The strength of the signal is determined by the number of players accessing the chest at any one time, meaning if you are the only person opening it, it will have a strength of one, which is hard to see. Of course, this also means a range of a measly one block, meaning you will have to boost it with a repeater or redstone torch construct.

/execute @p[rm=6] ~ ~ ~ /say The command worked
/execute @p[r=5] ~ ~ ~ /say The command did not work

(both after the /spreadplayers command). The only problem with that is that it will still act as if the command didn't work if a player gets positioned inside the 5 Blocks radius.

EDIT: It is now completely possible with the CommandStat Data Tag:

/blockdataCommand Block Coordinates{CommandStats:{SuccessCountName:"Fake Player Name / Entity / whatever you're gonna use",SuccessCountObjective:"Scoreboard Objective Name"}}

Basically, you can make the SuccessCount output to a scoreboard. See the video below for more info!

EDIT 2: Maybe I should mention that you can then do some sort of execute on the entity if it has a score of at least 1. Also, you should set the score back to 0 at the end of every tick (/cycle of the clock).

When using coordinates, you need to specify a radius so that it knows how far to search from that specific point. Try changing your command to:

/testfor @a[x=-611,y=80,z=714,r=1]

You can also compact it down into:

/testfor @a[-611,80,714,1]

I believe that the reason is that without a radius the selector makes no sense, so it is simply ignored and tests for @a.
