Getting Started
Runtime Spawner is a flexible, modular system for spawning enemies, NPCs, and objects at runtime - with support for pooling, progression, and multiplayer.
Version 2.0 introduces a package-based architecture and a new sample-driven onboarding flow to help you get up and running quickly.
1. Install the Package
Open Window → Package Manager
In My Assets, locate Runtime Spawner
Click Install
Once installed, the core package and any included modules will be available in your project.
Note: Runtime Spawner 2.x is designed around a modular architecture. Each addon is a separate Unity package (UPM) that creates clear boundaries for functionality and dependencies.
2. Open the Setup Window
After installation, open the Runtime Spawner setup tool:
Tools → Runtime Spawner → Setup
The Setup Window is your main entry point for:
Installing samples
Browsing available modules
Opening documentation for each setup
Note: you can install all of the samples via the Unity Package Manager window the same as normal, this window simply provides a shortcut / unified interface for installing them.
3. Install the Base Samples (Recommended)
We strongly recommend starting with the Core samples.
From the Setup Window:
Locate the Core / Base Samples
Click Install
Open the included scene(s)
Each sample includes a readme file with:
Setup instructions
Explanation of the components used
Suggested ways to experiment with the system
4. Explore Additional Samples
Depending on your needs, you can install additional samples:
Addon Samples
Global Spawner
Local Area Spawner
Waves
Spawnpoints (authored placement)
Networking Samples
Photon PUN
Photon Fusion
Each sample demonstrates a focused use case and builds on the core concepts.
5. Open the Sample Readmes
Every sample includes a readme file in the root folder of the installed sample.
From the Setup Window, you can:
Select a sample
Click Open Readme
These readmes explain:
What the sample demonstrates
How it is configured
How to adapt it to your own project
6. TextMesh Pro Essentials
Some sample scenes use a simple TextMesh Pro UI.
If prompted when opening a sample:
Click Import TMP Essentials
7. Understanding the System
Runtime Spawner 2.0 is built from:
Core Runtime Spawner (execution engine)
Spawn Director (pacing & intensity)
Addons (Global, Local Area, Waves, Spawnpoints)
Factories (pooling and networking)
You don’t need to understand everything upfront - the samples are designed to introduce these systems incrementally.
For a deeper overview, see: → Core Concepts → Designing Scenarios
8. Object Pooling
All spawning uses the integrated Object Pool system:
Objects are reused instead of instantiated/destroyed
Pools are created automatically
Fully compatible with networking
This ensures:
Better performance
Stable runtime behavior
Scalable spawning systems
9. Next Steps
Once you’ve run the base samples:
Explore addon samples (Waves, Local Area, Spawnpoints)
Review the Designing Scenarios guide
Set up your own spawner using a sample as a starting point
If you’re using multiplayer:
Install the PUN or Fusion samples
Follow their readme guides for setup
Recommended Approach
Start simple:
Run the Core sample
Add a single addon (e.g., Waves or Local Area)
Layer in additional systems as needed
This flow will help you understand how the pieces fit together without getting overwhelmed.
