2D Enemy Spawner System

2D Enemy Spawner System is a modular and extensible spawning framework for Unity designed for developers who want to build enemy wave systems quickly without sacrificing flexibility or performance.

Perfect for:

• Roguelikes
• Survivors-like games
• Arena shooters
• Bullet hell games
• Tower defense games
• Arcade projects
• Prototypes and game jams

This asset allows you to create reusable enemy spawning behaviors using customizable spawn patterns and ScriptableObjects, making wave creation fast, scalable, and easy to maintain.

Key Features

✅ Modular spawn system architecture

✅ Multiple built-in spawn patterns

✅ ScriptableObject workflow

✅ Integrated Object Pooling system

✅ Easy wave configuration

✅ Optimized for performance

✅ Gizmo visualization in Scene View

✅ Extensible architecture for custom patterns

✅ Beginner-friendly setup

✅ Lightweight and reusable across projects

Included Spawn Patterns

• Random
• Line
• Circle
• Square
• Spiral
• Cross
• Sides
• Sine Wave
• Heart
• Star

Built for Reusability

This asset was designed with reusability and scalability in mind.

Instead of hardcoding enemy behavior directly into the spawner, the system separates:

• wave data
• spawn logic
• pooling
• spawn patterns

This allows developers to easily integrate the system into existing projects and extend it with custom gameplay mechanics.

Object Pooling Included

The system includes an integrated Object Pooling solution to reduce unnecessary instantiation and destruction calls.

Benefits:

• Better runtime performance
• Reduced garbage collection spikes
• Smoother gameplay
• Better scalability for large enemy counts

Easy Setup

1. Import the package
2. Add the WaveManager to the scene
3. Create WaveData assets
4. Assign enemy prefabs
5. Press Play

You can have a complete enemy wave system running within minutes.

Custom Spawn Pattern Support

Developers can easily create their own spawn patterns by inheriting from the base SpawnPattern class.

Perfect for custom formations and unique gameplay scenarios.
