Sandbox++
Released
An open-source, community-driven successor to GMod's Sandbox. Work in progress!
Utility/CameraNoise/CameraNoiseSystem.cs
Camera noise system and base effect class. CameraNoiseSystem tracks BaseCameraNoise instances, updates them in PreSetup, applies modifications in PostSetup, and removes finished effects. BaseCameraNoise provides lifetime tracking, delta helper properties, automatic registration with the system, and virtual Update/ModifyCamera methods.
