Sandbox++
Released
An open-source, community-driven successor to GMod's Sandbox. Work in progress!
Utility/CameraNoise/Shake.cs
Camera noise component that applies a perlin-based shake to the camera while active. It stores lifetime and intensity, decays over time using deathTime, and modifies the camera rotation each frame by perlin noise multiplied by the remaining life and user screenshake preference.
