UNITY EDITOR TOOLING
House ScatterTool
A custom Unity Editor extension for fast prefab placement with live preview, snapping, rotation and raycast-based surface detection.
EDITOR WORKFLOW TOOL
01 / PURPOSE
Faster level placement
The tool was created to remove repetitive manual prefab placement from a level-design workflow.
A designer can choose a prefab, preview it directly in the scene, rotate it in fixed steps and place it while snapping to valid geometry.
02 / WORKFLOW
Editor-side features
Surface snapping
Raycasts detect placement surfaces and align the object to the intended position.
90° increments
Quick rotation controls make common architectural placement predictable.
Prefab selection
A lightweight editor interface lets the user swap the active prefab without leaving the placement flow.
03 / IMPLEMENTATION
Tool mechanics
- Raycasting: Determines valid placement locations in the scene.
- Preview lifecycle: Maintains a temporary representation without permanently modifying the scene.
- Placement: Instantiates the selected prefab only after user confirmation.
- Rotation state: Stores and applies deterministic orientation before placement.
