itemStack data

[steady ermine]

I can't put water bottle on the type id, but the minecraft:potion works but all potions got trigger

[modest smelt]

use testfor command

[modest smelt]

function isWaterBottle(player) {
    const testfor = player.runCommand('testfor @s[hasitem={item=potion,location=slot.weapon.mainhand,data=0}]').successCount;
    if (testfor > 0) return true;
    else return false;
}```

Where to put in?

@modest smelt

[modest smelt]

just call the function.

world.afterEvents.playerInteractWithEntity.subscribe(({ target, player, beforeItemStack, itemStack }) => {
   if (target.typeId === 'minecraft:creeper' && isWaterBottle(player)) {}
});```
