Perlin on GS_Play Gameplay Framework

Camera Noise Configurations

Mon, 01 Jan 0001 00:00:00 +0000

Camera shake comes in two flavors, both as Noise additives on a Phantom Camera’s stage list: PerlinNoise for continuous handheld sway and ImpulseNoise for event-triggered ADSR-gated bursts. Both consume the same .camnoiseprofile asset and the same six-axis Perlin layer model; they stack freely.

For the concept, the preset library, and how to trigger impulses from gameplay code, see The Basics: Noise & Impulse. For the underlying asset format, see Noise Profiles (Framework API).

Noise

The Noise namespace (GS_Core::Noise) provides a project-owned, stateless, deterministic, thread-safe Perlin noise toolkit. It backs every continuous-noise subsystem in the framework — PhantomCam Noise Profiles and the PerlinNoise / ImpulseNoise additive stages — plus any future UI wobble, unit idle-jitter, or VFX parameter modulation consumer that needs smooth time-varying values.

The same NoiseLayer struct documented below is what CameraNoiseProfile stores in its six per-axis vectors — no duplication. The utility is intentionally outside PhantomCam so non-camera consumers can adopt it without pulling a camera dependency.

Noise & Impulse

Mon, 01 Jan 0001 00:00:00 +0000

Camera shake comes in two flavors, both as Noise additives on a Phantom Camera’s stage list:

PerlinNoise — continuous Perlin-noise displacement. Use for handheld feel, idle sway, low-frequency wobble. Always sampling.
ImpulseNoise — event-triggered burst, gated by an ADSR envelope. Use for explosions, foot-stomps, gun kicks. Stays silent until you fire it.

Both consume the same .camnoiseprofile asset and the same six-axis Perlin layer model. Stack freely on the same cam — a baseline handheld profile plus an event-triggered impact profile is the canonical combination.

Noise Profiles

A Camera Noise Profile is a .camnoiseprofile data asset that defines a layered Perlin-noise shape. It is consumed by the PerlinNoise (continuous) and ImpulseNoise (event-triggered) additive stages. Profiles are reusable — one “Handheld_subtle” profile can drive both a baseline sway and a triggered impact burst at different intensities by adjusting per-stage gains.

Profiles are registered through PhantomCamDataAssetsSystemComponent alongside .camblendprofile and .camorbit. The asset reflects with EnableForAssetEditor so the Asset Editor opens it directly.
