Item entity rotation

[hollow dome]

Hi,
I want to recreate the dragon hearth dropped effect of draconic evolution mod for a minecraft item ritual: I wrote this code but I don't know how to add rotation.
Thanks in advance.

BlockEvents.rightClicked('netherite_block', event => {
    const { level, block, server } = event

    let itemEntity = level.createEntity("item")
    itemEntity.y = block.pos.y + 1
    itemEntity.x = block.pos.x + 0.5
    itemEntity.z = block.pos.z + 0.5
    itemEntity.item = Item.of('netherite_ingot')
    itemEntity.item.count = 1
    itemEntity.noGravity = true
    itemEntity.motionY = 0.04
    // itemEntity.rotate($Rotation.NONE) // I don't see any difference...
    itemEntity.customName = 'Cosmos'
    itemEntity.customNameVisible = true
    server.tell(`Spawned! at ${itemEntity.x} ${itemEntity.y} ${itemEntity.z}`)
    itemEntity.spawn()
})

wdym by rotate like have it spin on the ground?

[hollow dome]

Yes, but with rotation velocity increased.

[humble osprey]

i think you might need pitch and yaw

[hollow dome]

What are those?

[finite sluice]

fancy rotation words

[humble osprey]

minecraft uses them for rotation, https://simple.wikipedia.org/wiki/Pitch,_yaw,_and_roll

[finite sluice]

have you seen any other packs do it?

[humble osprey]

I have a script I found that uses it

ill send it

[hollow dome]

Thanks.

[hollow dome]

No.

@knotty anchor made this a while back

1 sec its too big XD

|function yawdelta(standard,target){
    let ntarget=target
    if(standard>ntarget){ntarget+=360}

not quite sure how he did it, but that might give you somewhat of an idea of how it works. I dont 100% understand i

[hollow dome]

Ok, I'll try with this.

[humble osprey]

im not sure, but ItemEntity might have a pitch, yaw, roll paramater, you can check with probejs

[hollow dome]

Yes, itemEntity has pitch and yaw parameters. I'll try with their.

[humble osprey]

ok

sounds good

[hollow dome]

I check player.yaw using PlayerEvents.tick and it's a value into range [-180, 180]. I tried change yaw to spawned item but I don't see effects.

BlockEvents.rightClicked('netherite_block', event => {
    const { level, block, server } = event

    let itemEntity = level.createEntity("item")
    itemEntity.y = block.pos.y + 1
    itemEntity.x = block.pos.x + 0.5
    itemEntity.z = block.pos.z + 0.5
    itemEntity.item = Item.of('netherite_ingot')
    itemEntity.item.count = 1
    itemEntity.noGravity = true
    itemEntity.motionY = 0.04
    itemEntity.customName = 'Cosmos'
    itemEntity.customNameVisible = true
    server.tell(`Spawned! at ${itemEntity.x} ${itemEntity.y} ${itemEntity.z}`)
    itemEntity.spawn()

    server.scheduleRepeatingInTicks(1, e => {
        let value = 0
        if (itemEntity.yaw == -180) {
            value = 1
        } else {
            value = -1
        }

        itemEntity.yaw = itemEntity.yaw + value
        server.tell(`Yaw ${itemEntity.yaw}`)
    })
})

[humble osprey]

i think it might be because your resetting the value at he beginning of your loop

you let value = 0 then you set it to 1 or -1, thats not much of a noticeable difference on a 360 degree axis

[hollow dome]

Ok, I put the value out.

[hollow dome]

I'll try with 36.

[humble osprey]

i gotta get some sleep soon, i can try to help when i wake up if you still need it

[hollow dome]

Ok, thanks.
