Snap Grid Manager is a powerful and intuitive editor+runtime prefab placement system designed for Unity developers building RTS, simulation, or sandbox-style games.

It includes:

  •  Snap-to-Grid Placement: Click anywhere on the terrain and place prefabs snapped to a customizable grid.
  •  Rotation & Preview: Rotate prefabs with one key and preview placements live using a transparent ghost system.
  •  Path-Based Placement: Use mouse clicks to define a curved or straight path, then automatically place prefabs along that path using Catmull-Rom or linear interpolation.
  •  Terrain Flattening: Auto-flattens terrain before placing structures to prevent clipping.
  •  Editor & Play Mode Support: All features work both inside the Editor and during runtime (ideal for custom level editors or God Mode debug tools).
  •  Randomizer: Apply random rotation, scale, and materials for natural variation.

Parts of this tool were initially prototyped using AI-assisted scripting (ChatGPT by OpenAI).
All code was manually reviewed, optimized, and extended by the developer to ensure real-world usability, bug-free performance, and editor integration.

No AI-generated assets (textures, models, audio) are included — only custom code and prefabs created specifically for this package.

The final system has been playtested, structured for maintainability, and packaged by hand.
