Overview

RTG Lite is a focused transform gizmo system designed specifically for runtime use in Unity.

It allows you to move, rotate, and scale objects at runtime using familiar editor-style gizmos, without relying on UnityEditor APIs or editor-only workflows.

Core Features

Transform Gizmos

Move / Rotate / Scale (TRS) runtime gizmos
Axis-based manipulation
World and Local space support
Stable and deterministic behavior

Editor-Style View Gizmo

Familiar scene view gizmo for camera orientation
Quickly switch between Top / Front / Side views
Intuitive camera reorientation

Camera Navigation System

Navigate your scene with familiar Unity Editor controls:

Orbit
Focus
Pan
Zoom
Perspective / Orthographic projection switch

Undo / Redo

Built-in undo / redo system for object transformations
Safely experiment and revert changes at runtime

Grid System

Optional visual grid for placement and alignment
Configurable cell size and appearance

Snapping

Position, rotation, and scale snapping
Precision control for runtime editing

Shortcut Configuration

Fully customizable keyboard shortcuts
Configure gizmo modes, snapping, camera controls, and more

RTG Lite is ideal for:

Runtime level editors
In-game building systems
Debug and developer tools
Prototyping and internal tooling
Projects that need runtime manipulation without full editor complexity

🛠️ Fixes & Improvements

ShortcutCategory.FindOrCreateShortcut() now synchronizes the structural definition of an existing shortcut (command and context) when a shortcut with the same name is found.
Added RegisterObjectHierarchies() to RTScene to support batch registration of newly created object hierarchies.
Fixed an issue where ViewGizmo could trigger a projection switch when the mouse button was released over the projection label immediately after dragging a gizmo.
