C++ Quick Reference

// Play (simple)
UERP_ImpactStatics::PlayResponse(this, Target, Asset, IntensityOverride);

// Play (full context)
FERP_ImpactContext Ctx = UERP_ImpactStatics::MakeImpactContextFromHit(Hit, Damage);
UERP_ImpactStatics::PlayResponseWithContext(this, Asset, Ctx);

// Stop
UERP_ImpactStatics::StopAllOnActor(this, Target);

// Channel muting
UERP_ImpactStatics::MuteChannel(this, FGameplayTag::RequestGameplayTag("ElysImpact.Channel.Audio"));
UERP_ImpactStatics::UnmuteChannel(this, AudioChannel);
UERP_ImpactStatics::SetChannelIntensity(this, CameraChannel, 0.5f);

// Global intensity
UERP_ImpactStatics::SetGlobalIntensity(this, 0.5f);

// Feel Profile
UERP_ImpactStatics::SetFeelProfile(this, MyProfile);

// Dramatic Intensity
float DI = UERP_ImpactStatics::GetDramaticIntensity(this, Target); // [0..1]
UERP_ImpactStatics::ResetDramaticIntensity(this, Target);

// Subsystem direct access
UERP_ImpactSubsystem* Sub = UERP_ImpactSubsystem::Get(this);

Common Patterns

Hit Response on Character

1. Response Asset with: Camera Shake + Sound Effect + Scale Punch + Material Flash
2. All on channel ElysImpact.Channel.Hit
3. DramaticContribution: 0.5
4. Call from OnTakeAnyDamage with Magnitude = DamageAmount

Explosion Area Response

1. Response Asset with: Camera Shake (Attenuate by Radius) + Chromatic Aberration + Bloom Pulse + Particle Effect
2. Set ChoreographyGroup.GroupTag to Impact.Explosion
3. PrimaryLockDuration: 1.0, MaxSecondaryCount: 3
4. Call on all actors in explosion radius — Choreography handles visual budget

Menu / Pause Profile

1. Create UERP_FeelProfile with:
   • bSuppressAudio: true
   • bSuppressCameraEffects: true
   • bSuppressParticles: true
   • GlobalIntensityScale: 0.0
2. SetFeelProfile(this, PauseProfile) on pause, SetFeelProfile(this, nullptr) on resume

Per-Platform Intensity

// In GameInstance BeginPlay:
float Scale = UGameUserSettings::GetGameUserSettings()->GetOverallScalabilityLevel() / 3.f;
UERP_ImpactStatics::SetChannelIntensity(this, PostProcessChannel, Scale);
UERP_ImpactStatics::SetChannelIntensity(this, ParticleChannel, Scale);
