Minecraft – Right click detection on a block (No item on hand) Minecraft

minecraft-commandsminecraft-java-edition

How can I modify this code to detect a right click when right-clicking a specific block only, without any item in a player hand? This is not like others, for I am not using an Item or I am not right-clicking any object. Just a specific one like a torch, to act like a button. I can use scorebords with this though.

/scoreboard players set @e[type=ArmorStand,name=Activated] action 1 {Equipment:[{},{},{},{},{}]}
/scoreboard players set @e[type=ArmorStand,name=Activated] action 0 {Equipment:[{id:"minecraft:carpet"},{},{},{},{}]}
/execute @e[name=Activated,score_action_min=1] ~ ~ ~ /setblock XYZ-Coordinates redstone_block
/execute @e[name=Activated,score_action=0] ~ ~ ~ /setblock Same XYZ-Coordinates air

You can do this using a villager with no trades and a stat.talkedToVillager objective. This is because a villager without trades doesn't show the trade interface at all.

Summon an invisible ArmorStand with an invisible, silent Villager as it's passenger, like this:

/summon ArmorStand <x> <y> <z> {
  Invisible:1b,
  Marker:1b,
  NoGravity:1b,
  Passengers:[{
    id:Villager,
    Silent:1b,
    NoAI:1b,
    Invulnerable:1b,
    Career:1,
    CareerLevel:6,
    Offers:{Recipes:[]},
    ActiveEffects:[{
      Id:14b,
      Amplifier:0b,
      ShowParticles:0b,
      Duration:2147483647
    }]
  }]
}

Copy-paste version of the command:

/summon ArmorStand <x> <y> <z> {Invisible:1b,Marker:1b,NoGravity:1b,Passengers:[{id:Villager,Silent:1b,NoAI:1b,Invulnerable:1b,Career:1,CareerLevel:6,Offers:{Recipes:[]},ActiveEffects:[{Id:14b,Amplifier:0b,ShowParticles:0b,Duration:2147483647}]}]}

The armor stand serves purely as a way to hold the villager in place. Play around with <x> <y> <z> until you find a good position for the villager. I suggest temporarily removing the villager's invisibility effect for "alignment" by replacing 2147483647 with 0.

Now, create your objective

/scoreboard objectives add torchLever stat.talkedToVillager

Use a repeat/chain command block line to run the following commands:

/execute @a[x=X,y=Y,z=Z,r=R,score_torchLever_min=1] ~ ~ ~ <your command>
/scoreboard players set @a torchLever 0

Replace X, Y, Z and R with appropriate values. This is to prevent triggering your torch lever when interacting with any villagers.

Context:

In the Minecraft 14w08a, a snapshot between 1.8 and 1.7, you can now test for an item in a player's inventory by clearing 0 items of that type, as in the snapshot, it added the ability to specify the number of items to remove.

/clear [Player] [Item] [Data] [Count] [NBT Tags]

Except, it means that we have to identify the person and there is no way that you can capture the person in this. So, we need to give the player an identifier.

How do we do it?

enter image description here
This is a module. Repeat this contraption as many times as the number of players you want to track. So, 50 players means making this 50 times, but substituting the playerID for a different number, preferably plus one to the previous one.

Step 1: Create an identifier.
Using command blocks, you'll have to assign each player you want to test a value in a dummy score. Let's make a score called playerID that is a dummy value.

/scoreboard objectives add playerID dummy playerID

So, whenever you want to test for a player (if it's a PvP/command-block related map, all players have to be assigned a number when the connect/join the game; not spectating).

Step 1b.

Create a gate. All players have to go onto it when the game starts. When the first player steps on it, they are assigned a scoreboard value in the objective "playerID". This is what we'll be using to identify each player.

/scoreboard players set @p playerID 1

Now, the next player should either have to go onto another pressure plate, or you can make that same pressure plate give a different number (more complicated, not going to say how).
Based on your comments, make a second gate for the second player and so on.

This gate should have /scoreboard players set @p playerID 2 and so on.

Step 2: Now, we'll have to a /testfor for each player.

Place a fast clock (at about 10Hz; turns on 10 times a second). You may go faster - But it will not work with repeaters/comparitors etc. That pulse goes into a command block with this command:

/clear @p[score_playerID=1,score_playerID_min=1] minecraft:Skull 0 0

This will clear the player with the playerID score of 1 zero Skulls.
If the player has a Skull in their inventory, it'll clear none of it and output 'true'.
If the player doesn't have a Skull in their inventory... (Although it's trying to clear no skulls, it checks if there are skulls. /clear commands output false if the item is not found, reguardless of how many needs to be removed.)

So, place a comparitor facing out of that /clear [blah blah blah] command block outputting to another command block. Now, let's put the "Oh, this guy fits this citeria."

/scoreboard objectives create hasSkull dummy hasSkull
/scoreboard players set @p[score_playerID=1,score_playerID_min=1] hasSkull 1

If you want the score to automatically revert to 0 when the player loses the skull, just make a flip-flop gate (one that outputs to the left if the input is on, and to the right if the input is off etc.), with when the input is false, it outputs a signal to a command block that does:

/scoreboard players set @p[score_playerID=1,score_playerID_min=1] hasSkull 0

Step 3: The annoying bit.
Now, repeat as many modules as you need for players. This time, change the score you're testing for, for example: /clear @p[score_playerID=2,score_playerID_min=2] minecraft:Skull 0 0 instead of /clear @p[score_playerID=1,score_playerID_min=1] minecraft:Skull 0 0 etcra.

Step 4: Doing something with them.
Now that you have an objective that gives a score of '1' to anyone with a skull in their inventory... Or '0' to those without one, you can just make a command block which does things to the players with the score of 1.

Create a command block that tests for this, on a 20Hz clock (refreshes 20 times a second, the fastest possible clock)... Or slower if you wish.

/[something] @p[score_hasSkull=1,score_hasSkull_min=1] [more parameters]

For example: /kill @a[score_hasSkull=1,score_hasSkull_min=1] (Kills everyone who has a skull)

Minecraft item right/left click detection

In the video you linked from sethbling, he is actually just detecting the snowballs that are thrown, as snowballs are throw able. He's not detecting right clicks.

If you want to detect when an item is right clicked, the simplest method is to have an armor stand teleported exactly to you, and when you click the item, it the item will actually be put in to the armor stand's hand, which can then be detected. Once that's detected, you give the player another item, and set the armor stand's hand to empty. Rinse and repeat.

More info and commands can be found in this video:

and many others.
