Jutsu Handler (All-in-One)

Instead of importing each jutsu class separately, you can import CustomNPCJutsuHandler and call everything through it.

var jutsu = Java.type("narutodestination.Mathioks.CNPC.CustomNPCJutsuHandler");

This one import gives you access to all standard jutsus, Magnet Push, and jutsu block breaking.

Standard Jutsus

Every standard jutsu has the same three method patterns. Using fireball as an example:

jutsu.fireball(npc)                      // default damage + cooldown
jutsu.fireball(npc, 50.0)               // custom damage
jutsu.fireball(npc, 50.0, 100)          // custom damage + cooldown (20 ticks = 1 sec)
jutsu.fireballPercent(npc, 5.0, 0.5)    // 5 base + 50% of target's max HP
jutsu.fireballPercent(npc, 5.0, 0.5, 60) // same with custom cooldown

All return boolean — true if the jutsu was cast, false if it was on cooldown.

Magnet Gold Push (Continuous)

Continuous jutsu — fires gold dust repeatedly for a short burst. Needs magnetPushUpdate() called every tick.

magnetPush(npc) / magnetPush(npc, damage) / magnetPush(npc, damage, cooldown)

Start the jutsu.

jutsu.magnetPush(event.npc);
jutsu.magnetPush(event.npc, 8.0);
jutsu.magnetPush(event.npc, 8.0, 60);

magnetPushPercent(npc, base, percent) / magnetPushPercent(npc, base, percent, cooldown)

Start with percentage-based damage.

jutsu.magnetPushPercent(event.npc, 5.0, 0.3); // 5 base + 30% of target max HP

magnetPushUpdate(npc)

Must be called every tick. Without this, the jutsu won't fire.

jutsu.magnetPushUpdate(event.npc);

magnetPushIsActive(npc)

Returns true if the jutsu is currently firing.

magnetPushStop(npc)

Force stop the jutsu.

Jutsu Block Breaking

Same methods as the Jutsu Utilities page, accessible through the handler.

jutsu.breakJutsuBlocks(npc)                          // defaults: radius 5, cooldown 40, effects on
jutsu.breakJutsuBlocks(npc, radius)
jutsu.breakJutsuBlocks(npc, radius, cooldown)
jutsu.breakJutsuBlocks(npc, radius, cooldown, false)  // silent (no effects)
jutsu.breakJutsuBlocksSphere(npc, radius, cooldown)
jutsu.breakJutsuBlocksSphere(npc, radius, cooldown, false)

jutsu.hasJutsuBlocksNearby(npc, radius)   // boolean
jutsu.countJutsuBlocks(npc, radius)       // int

jutsu.isBlockBreakerOnCooldown(npc)       // boolean
jutsu.clearBlockBreakerCooldown(npc)

jutsu.playBlockBreakEffects(npc, x, y, z)
jutsu.playBlockBreakEffectsAtNpc(npc)

---

Example: Multi-Jutsu Boss

Using the handler you only need one import for everything:

var jutsu = Java.type("narutodestination.Mathioks.CNPC.CustomNPCJutsuHandler");

function init(event) {
    event.npc.setStoredData("phase", 1);
}

function tick(event) {
    var npc = event.npc;
    var target = npc.getAttackTarget();
    jutsu.magnetPushUpdate(npc);

    if (target == null) return;

    var hp = npc.getHealth() / npc.getMaxHealth();

    // Phase transition at 50% HP
    if (hp < 0.5 && npc.getStoredData("phase") < 2) {
        npc.setStoredData("phase", 2);
        npc.say("\u00a75You've pushed me this far...");
    }

    // Clear jutsu blocks
    if (jutsu.hasJutsuBlocksNearby(npc, 6)) {
        jutsu.breakJutsuBlocks(npc, 6, 40);
    }

    // Attack based on phase
    var phase = npc.getStoredData("phase");
    var random = Math.random();

    if (phase >= 2) {
        if (random < 0.3) {
            jutsu.meteor(npc, 50.0, 300);
        } else if (random < 0.6) {
            jutsu.fireballPercent(npc, 10.0, 0.3, 60);
        } else {
            jutsu.magnetPush(npc, 8.0, 40);
        }
    } else {
        jutsu.fireball(npc, 25.0, 100);
    }
}

Handler vs Individual Imports

Both approaches work the same. The handler just saves you imports.

Handler (one import):

var jutsu = Java.type("narutodestination.Mathioks.CNPC.CustomNPCJutsuHandler");
jutsu.fireball(event.npc, 30.0);
jutsu.meteor(event.npc, 50.0);

Individual classes (one import per jutsu):

var Fireball = Java.type("narutodestination.Mathioks.CNPC.Jutsus.FireballJutsu");
var Tengai = Java.type("narutodestination.Mathioks.CNPC.Jutsus.TengaiJutsu");
Fireball.cast(event.npc, 30.0);
Tengai.cast(event.npc, 50.0);

Use whichever you prefer. The individual classes use cast() / percent(), the handler uses the jutsu name directly.
