Projectile.h(50): [C2065] 'UMatineeCameraShake': undeclared identifier

[Marcna1]

I am trying to follow the tutorial that use UE 4.25 in UE5 but then I use this code:

UPROPERTY(EditAnywhere, Category="combat")
TSubclassOf<UMatineeCameraShake> HitCameraShake;

Projectile.h(50): [C2065] 'UMatineeCameraShake': undeclared identifier

you need to forward declare the UMatineeCameraShake.

TSubclassOf< class UMatineeCameraShake > HitCameraShake;
