Hot Dogs, Horseshoes & Hand Grenades Update 120 Adds Save and Load for Signals
The latest experimental update for Hot Dogs, Horseshoes & Hand Grenades introduces full save and load support for the Gameplanner Signals System, alongside new logic devices and visual wiring indicators.
Experimental Branch players in Hot Dogs, Horseshoes & Hand Grenades can now test persistent circuitry. Update 120 Experimental 13 brings save and load functionality to the Gameplanner Signals System, opening the door for complex contraptions.
Signals System Save and Load Support
Signals system connections now properly save and load across sessions. This update allows players to construct complex automated contraptions and logic circuits without losing their wired configurations when restarting the game.
New Devices and Visual Tools
Three new signals devices have been added to the sandbox: the Laser Sensor, the Signals Sequencer, the Signals Patterner, and the Signals Router. To help manage complex wiring, signals connections are now drawn using 2D symbols that provide clear visual distinction between inputs and outputs. Furthermore, active connections will dim when invalid links are targeted with the Pointer tool.
Why this patch matters
By adding save persistence to the Signals System, H3VR turns into an even more powerful sandbox for mechanical and logical engineering.
