Run JS function on specific item use (right click)

[fickle smelt]

You can use the ItemUse event to listen for item interactions
also for running functions using commands, you can probably use the ScriptEventReceive event and the /scriptevent command

world.afterEvents.itemUse.subscribe((data) => {
    if (data.itemStack.typeId == "minecraft:stick") {
        data.source.sendMessage("Hello World!");
    };
});

and for the command thing

• Command: /scriptevent test:say hello

system.afterEvents.scriptEventReceive.subscribe((data) => {
    if (data.id == "test:say") {
        world.sendMessage(data.message);
    };
});

Stunning, thanks!

One more thing, I found block placement with JS quite confusing in the docs. Do you have example for that? 🙏

[fickle smelt]

//Gets the overworld dimension
let overworld = world.getDimension("minecraft:overworld");

//Gets the block at X: 1 / Y: 2 / Z: 3 from the overworld
let block = overworld.getBlock({ x: 1, y: 2, z: 3 });

//Sets the block to "minecraft:bedrock"
block.setType("minecraft:bedrock");

I would run a command from JS, but docs say that it's better to run native methods.

[mystic swift]

Perfect! Tyvm. 💙

Is it possible to use relative coordinates here? I need to place some blocks to the place, where player right clicks with custom item in hand.

[fickle smelt]

If you’re trying to set a block where the pkayer is interacting then you can probably use this

world.afterEvents.playerInteractWithBlock.subscribe((data) => {
    if (data.itemStack && data.itemStack.typeId == "minecraft:stick") {
        data.block.setType("minecraft:bedrock");
    };
});

[mystic swift]

Awesome! And there currently isn't native method for spawning in structures, right?

So, I have to call structure command instead.

[fickle smelt]

Yeah, there isn’t one yet

[mystic swift]

It doesn't work as expected the data are apparently undefined.

[Scripting][error]-Plugin [Nogard BP - 1.0.0] - [main.js] ran with error: [TypeError: cannot read property 'subscribe' of undefined    at <anonymous> (main.js:18)
]

[fickle smelt]

Which version of the module are you using?

[mystic swift]

Stable.

        {
              "module_name": "@minecraft/server",
              "version": "1.7.0"
        }

[fickle smelt]

Ah, that's why, the PlayerInteractWithBlock is only in beta currently but we might be able to use the ItemUseOn event

[mystic swift]

But will we be able to tell which block player is facing, when using the item?

[fickle smelt]

I just realised that this might not be possible in stable sadly
the ItemUseOn event only gets triggered when the item gets used on a block

[mystic swift]

So with ItemUseOn we have to specify the block?

Anyway, hmmm, so, it will work in 1.8.0-beta, right?
Okay, on my way to try it.

Okay, that's cool, it replaces the actual block.
Would it be possible to get location of the block player clicked at?

[fickle smelt]

It is possible

data.block.location

[mystic swift]

This returns vector?

[fickle smelt]

it returns Vector3

[fickle smelt]

player.runCommand(`/structure load nogard:start ${data.block.location.x} ${data.block.location.y} ${data.block.location.z} 0_degrees`);
