Spear Spawner Enemy Setup

This setup provides a guide for setting up a ranged Spear Spawner Enemy using the Boss AI Toolkit in Unity. It covers model setup, configuration cloning, custom animation registration, projectile spawner setup, and projectile prefab configuration.

1. Initial Setup

Steps

  1. Drag the 3D spear spawner model into the scene hierarchy.
  2. Right-click the GameObject and select Prefab > Unpack Prefab Completely.
  3. Rename the GameObject to Spear Spawner Enemy New.
  4. Assign the required character material to the model mesh.

2. Cloning Enemy Configuration

Duplicate configuration settings from the existing Spear Spawner Enemy template prefab.

Steps

  1. Navigate to Tools > Boss AI Toolkit > Duplicate Enemy.
  2. Configure cloning settings:
  3. Source Boss: Drag in the template Spear Spawner Enemy prefab.
  4. Target Boss: Drag in the newly prepared Spear Spawner Enemy New GameObject.
  5. New Boss Name: Set to Spear Spawner Enemy New.
  6. Avatar: Drag and drop the model's target Avatar asset.
  7. Create New Animator Controller: Uncheck (reuses the base template's existing animation controller asset).
  8. Weapon: Uncheck.
  9. Click Start Cloning Configuration and close the window.

3. Global Settings & Rotation Animations

Configure turning behaviors and register turning clips.

Steps

  1. Select Spear Spawner Enemy New and expand Enemy Ability System > Global Settings:
  2. Use Rotation Animations: Checked.
  3. Rotate Spine: Unchecked.
  4. Under Rotation Animations, add two direction entries:
  5. Left: Choose the left turning clip (turn left), enable Apply Root Motion, and click Auto Get Length.
  6. Right: Choose the right turning clip (turn right), enable Apply Root Motion, and click Auto Get Length.

Note: If rotation animation clips are missing, add the Animation Setup Tool component to the enemy. Assign the Animator Controller, register the clips with parameter names, click Add to Animator Controller, and select them from the rotation animation dropdown.

4. Health UI & Hit Reactions

Configure health UI, death modes, and hit response timings.

Settings

  • Health & UI:
  • Spawn Health Bar Prefab: Enabled (spawns an health bar).
  • Death Mode: Set to Die Using Animations. Add a dying animation clip and check Apply Root Motion. (Or set to Die Using Ragdoll Physics).
  • Hit Reactions:
  • Time To Destroy Spawn Impact Effect: 0.5 seconds.
  • Min / Max Hit Interval: 1 second.

5. Ranged Spawner Ability Configuration

Step 5.1: Distance Group & Ability Setup

  1. Under Combat Attack System, set Phase 0 Health Range (0 - 100) and Initial Attack Delay to 1 second.
  2. Create/edit a distance group with range 5 to 200 meters.
  3. Add an ability and set Ability Type to Projectile Attack.
  4. Set power-up duration and assign the Magic animation clip to play while spawning.

Step 5.2: Spawn Point Setup

  1. Create an empty child GameObject under Spear Spawner Enemy New named Spear Spawn Point.
  2. Position Spear Spawn Point in front of the enemy (copy transform from the template prefab).
  3. In the Projectile Attack settings panel:
  4. Spawn Point: Assign the Spear Spawn Point transform.
  5. Projectile Parent: Assign the Spear Spawn Point transform.
    • Purpose: Parenting ensures the spawned spear rotates and stays aligned with the enemy while targeting before it is thrown.

6. Spear Projectile Prefab Configuration

Set up the projectile object and collision components.

Projectile Alignment & Components

  1. Mesh Orientation: Ensure the spear model's +Z axis (forward) points in the direction of movement.
  2. Team Member: Assign the Team Member component with the same team name as the enemy.
  3. Capsule Collider: Add a Capsule Collider and check Is Trigger.
  4. Hitbox Component:
  5. Set Owner to the spear itself and check Compare Enemy (assigning the spear's Team Member script).
  6. Auto Activate On Start: Checked.
  7. Deactivate Hitbox On Hit: Checked.
  8. Deactivate Hitbox After Time: Checked (5 seconds).
  9. Destroy Mode On Hit: Set to Destroy Owner (destroys the spear upon impacting the player).

Projectile Script Settings

Parameter Value Description
Moving Delay 0 Delay before movement begins.
Move Speed 20 Forward travel velocity.
Rotation Mode None Disables spinning/facing changes during flight.
Move Forward Only Checked Forces the spear to fly straight ahead instead of tracking the player dynamically.
Unparent On Move Checked Detaches the spear from Spear Spawn Point as soon as movement begins.
  1. Apply changes to the Projectile Prefab asset and assign it to the Projectile Prefab field on the enemy's attack ability.

7. Verification Checklist

Before running tests in Play Mode, check the following configuration settings:

  • [ ] Rotation Animations: Turn left and turn right parameters linked with root motion enabled.
  • [ ] UI & Hits: Spawn health bar enabled and hit impact effect destroy delay set to 0.5s.
  • [ ] Spawn Transforms: Spear Spawn Point assigned as both Spawn Point and Projectile Parent.
  • [ ] Projectile Alignment: Spear mesh Z-axis oriented forward.
  • [ ] Projectile Script Options: Move Forward Only and Unparent On Move checked on the spear prefab.
