Installation Guide

To integrate AI Level Scatter into your project, follow this installation guide.

[!IMPORTANT] Commercial License Notice: This asset is a premium commercial utility and must be purchased exclusively through the Unity Asset Store. Downloading code from GitHub repositories or third-party distribution channels without a valid purchase license is illegal, breaks compiler dependencies, and voids all support.

Technical Requirements

Before importing the package, ensure your project environment meets the following specifications:

Requirement Specification
Unity Version Unity 2020.3 LTS, 2021.3 LTS, 2022.3 LTS, or newer.
Render Pipeline Compatible with Built-in RP, Universal Render Pipeline (URP), and High Definition Render Pipeline (HDRP).
Scripting Backend Compatible with both Mono and IL2CPP.
Physics Unity Physics (PhysX) with 3D Physics enabled (required for surface raycasts and collision filtering).

Step 1: Purchasing and Importing the Asset

  1. Open the Unity Asset Store in your web browser and purchase AI Level Scatter.
  2. Open your Unity Project.
  3. Open the Package Manager window (Window -> Package Manager).
  4. Select Packages: My Assets from the dropdown menu in the top-left.
  5. Search for AI Level Scatter and click Download, then click Import.
  6. In the Import window, ensure all files under Assets/Decnet are checked, and click Import.

Step 2: Verifying Assembly Definitions

To keep editor code isolated from your game runtime builds, the package is structured using Unity Assembly Definitions (.asmdef).

  1. After importing, verify that the assembly definition file Decnet.LevelScatter.Editor.asmdef exists under Assets/Decnet/AI Level Scatter/Editor/Assembly/.
  2. This editor assembly has references configured to Unity.Editor assemblies.
  3. If you have custom scripts that call the ScatterProfile ScriptableObject at runtime, ensure your runtime assemblies reference the core ScriptableObject profile, but do not reference the Editor assembly.

Step 3: Initializing Presets

To ensure the placement samplers have working demo prefabs and templates:

  1. Open the Unity menu: Tools -> Decnet -> Setup Default Presets.
  2. A dialog will confirm that three premium presets (Forest Floor, Rock Fall, and Debris & Clutter) along with procedural tree, rock, and grass demo prefabs have been initialized in your project.
  3. This creates the folders:
    • Assets/Decnet/AI Level Scatter/Presets/
    • Assets/Decnet/AI Level Scatter/DemoAssets/

Now that the asset is imported and default assets are configured, you are ready to proceed to the Quick Start Guide!
