Syntax

void MakeNoise
(
    float Loudness,
    APawn * NoiseInstigator,
    FVector NoiseLocation,
    float MaxRange,
    FName Tag
)

Remarks

Trigger a noise caused by a given Pawn, at a given location.

that the NoiseInstigator Pawn MUST have a PawnNoiseEmitterComponent for the noise to be detected by a PawnSensingComponent. Senders of MakeNoise should have an Instigator if they are not pawns, or pass a NoiseInstigator.

not supported for legacy PawnSensingComponent, only for AIPerception)

Parameters

Parameter	Description
Loudness	The relative loudness of this noise. Usual range is 0 (no noise) to 1 (full volume). If MaxRange is used, this scales the max range, otherwise it affects the hearing range specified by the sensor.
NoiseInstigator	Pawn responsible for this noise. Uses the actor's Instigator if NoiseInstigator is null
NoiseLocation	Position of noise source. If zero vector, use the actor's location.
MaxRange	Max range at which the sound may be heard. A value of 0 indicates no max range (though perception may have its own range). Loudness scales the range. (
Tag	Identifier for the noise.
