Some KubeJS notes about Minecraft
ServerEvents.tick((event) => {
const { server } = event;
if (server.tickCount % 2) return;
server.entities.filterSelector("@e[type=item]").forEach(
/** @param {Internal.ItemEntity_} itemEntity */
(itemEntity) => {
/** @type {{Item: { Count: Internal.ByteTag_, id: string }, Age: Internal.ShortTag_}} nbt */
const { Item: item, Age } = itemEntity.nbt;
const { descriptionId, rarity } = Item.of(item.id);
itemEntity.customName = [
Text.gold(`${item.Count}x`),
" ",
Text.translate(descriptionId).color(rarity.color),
" ",
Text.gray(
`(${Age == -32768 ? "∞" : ((6000 - Age) / 20).toFixed(1)}s left)`
),
];
itemEntity.customNameVisible = true;
}
);
});Kubejs has a feature known as beans which allows you to make scripts a tad more readable.
Anything getXy() can be gotten with xy, anything setXy(value) can be set with xy = value and anything isXy() can be checked with just xy.
You can use preprocess arguments at the beginning of your script, as follows:
| Name | Purpose | Parameter Type | Description | Default Value |
|---|---|---|---|---|
priority |
Load Priority | Integer(Number) | The higher the number, the earlier it loads | 0 |
ignored |
Ignore Load | Boolean | If true, it skips loading | false |
packmode |
Module Pack Mode | String | If the module pack mode is not equal to the input value, it skips loading | default |
requires |
Namespace Requirement | String | If the namespace is not loaded, it skips loading | (none) |
