Opis
RuntimeCoordAxis is a complete in-game runtime transform editing & viewport auxiliary tool built for Unreal Engine 5, fully developed with Blueprints, no editor-only dependencies, fully available in PIE and packaged projects.
Perfect for custom runtime editors, BIM digital twin, industrial simulation, 3D scene browsing and independent viewport interaction systems.
Core Features
1. Four Transform Editing Modes
Integrated full-process object transformation logic, switchable by shortcut keys：
Select Only Mode（Key 1）
Move Translation Mode（Key 2）
Rotation Mode（Key 3）
Scale Mode（Key 4）
Single Selection：Left Mouse Button
Additive Selection：Ctrul + Left Mouse Button
Subtractive Selection：Alt + Left Mouse Button
2. Space Coordinate System Switch
Support World Space / Local Space switching
Adapt to directional offset and attitude rotation of complex components and models
3. Complete Grid Snap System
Dual space snapping：World Grid / Relative Grid
Support Move Grid Snap, Rotation Angle Snap, and Scale Step Snap
4. Free Flying Camera Control
Standard 3D viewport camera operation：
Move Forward / Backward：W、S
Move Left / Right：A、D
Move Up / Down：E、Q
Adjustable camera movement speed, support fast browsing and fine inspection
5. One-Click Viewport Auto Fit
Shortcut F to auto-fit all selected Actors
Calculate camera safe distance based on FOV perspective formula
6. Runtime Widget Transform Panel
Built-in independent UI widget：
Real-time display Actor Location / Rotation / Scale data
Directly edit transform parameters through UI input
Control selected actors’ transform values visually
7. Undo & Redo Function
Undo：Ctrl + Z
Redo：Alt + Z
Record transform operation stack, realize rollback and recovery of editing behavior
8. High-Performance Runtime Axis Gizmo
Red/Green/Blue standard three-axis display, dynamic follow selected actors, lightweight rendering, low performance cost, stable operation for long-time use.
9. Orbit Camera Around Selected Actor
When an Actor is selected: Press Alt + Right Mouse Button to orbit the viewport around the selected object, enabling intuitive inspection of the object from all angles.
