[ISS / KubeJS] Displaying Variable Data for Custom Spell

[pseudo fern]

When registering a custom spell, where do you create the in-game reference of the spells variable data? For example, I'd like to display my spell's radius for the player to see (i.e display finalRadius)

  event.create('taunt')
    .setCastTime(0)
    .setCooldownSeconds(5)
    .setManaCostPerLevel(20)
    .setCastType('instant')
    .setSchool('irons_spellbooks:evocation')
    .setMinRarity('common')
    .setMaxLevel(1)
    .setStartSound('minecraft:entity.ravager.roar')
    .setAllowLooting(true)
    .canBeCraftedBy(player => true)
    .needsLearning(false)
    .onCast(ctx => {
      const player = ctx.entity;
      const level = ctx.level;

      if (!player || !player.getAttributeValue) {
        console.log("Taunt spell cast by non-player or undefined entity.");
        return;
      }

      const exemptEntities = [
        "minecraft:item",
        "labels:label",
        "simplehats:hatdisplay",
        "minecraft:armor_stand",
        "minecraft:item_frame",
        "minecraft:glow_item_frame",
        "corpse:corpse",
        "irons_spellbooks:spectral_steed",
        "irons_spellbooks:summoned_polar_bear",
        "irons_spellbooks:summoned_skeleton",
        "irons_spellbooks:summoned_zombie",
        "irons_spellbooks:summoned_vex",
        "irons_spellbooks:summoned_claymore",
        "irons_spellbooks:summoned_rapier",
        "irons_spellbooks:summoned_sword",
        "irons_spellbooks:spectral_hammer"
      ];

      const baseRadius = 6;
      const spellPower = player.getAttributeValue("irons_spellbooks:spell_power") || 1;
      const evocationSpellPower = player.getAttributeValue("irons_spellbooks:evocation_spell_power") || 1;
      const finalRadius = Math.round(baseRadius * spellPower * evocationSpellPower * 10) / 10;

      const aabb = AABB.of(
        player.x - finalRadius, player.y - finalRadius, player.z - finalRadius,
        player.x + finalRadius, player.y + finalRadius, player.z + finalRadius
      );

      level.getEntitiesWithin(aabb).forEach(entity => {
        if (exemptEntities.includes(entity.getType().toString())) return;

        if (!entity.nbt.contains("Owner") && !entity.nbt.contains("Trusted") && entity.getType().toString() !== "minecraft:player") {
          try {
            entity.setTarget(player);
            level.spawnParticles('minecraft:angry_villager', true, entity.x, entity.y + entity.eyeHeight + 0.25, entity.z, 0.15, 0.15, 0.15, 3, 0);
          } catch (error) {
            console.log(`Error changing target of ${entity.getName()}: ${error}`);
          }
        }
      });
    });
});

Looks like you may need to do a java load class.

@shell flicker another ISS ticket for ya

should be able to get the spell's power by doing this #1258601167550812302 message

.setUniqueInfo((level, caster) => {
            let spellStrength = caster.getPlayerMagicData().getCastingSpell().getSpell().getSpellPower(level + 1, caster)
            return [Component.of(`Damage: ${spellStrength * 20}`), Component.of(`AoE Damage: ${level}`)]
        })

should have this functional now, now I truely understand why level and caster exist, since you can't get the player in the spell registry
