Crouch and prone mechanics

So I’m trying to make crouch and prone mechanics in ue 5.6 cpp.I looked on the internet and couldn’t find any good tutorial about this topic especially for cpp. I made something like this but this code doesn’t work for switching from crouch to prone.

void APlayerCharacter::SetStance(EStanceState NewStance)

{

if (CurrentStance == NewStance) return;



switch (CurrentStance)

{

case EStanceState::Crouch:

   UnCrouch();

   break;

case EStanceState::Prone:

   UnProne();

   break;

}

CurrentStance = NewStance;

   

switch (CurrentStance)

{

case EStanceState::Stand:

   GetCharacterMovement()->MaxWalkSpeed = MovementSpeed;

   break;

case EStanceState::Crouch:

   Crouch();

   GetCharacterMovement()->MaxWalkSpeed = CrouchSpeed;

   break;

case EStanceState::Prone:

   Prone();

   break;

}

}

void APlayerCharacter::OnCrouchPressed()

{

const EStanceState Target = (CurrentStance == EStanceState::Crouch) ? EStanceState::Stand : EStanceState::Crouch;

SetStance(Target);

}

void APlayerCharacter::OnPronePressed()

{

if (CurrentStance != EStanceState::Stand && !CanStand())

{

   UE_LOG(LogTemp, Warning, TEXT("Can't stand!!"));

   return;

}



const EStanceState Target = (CurrentStance == EStanceState::Prone) ? EStanceState::Stand : EStanceState::Prone;

SetStance(Target);

}

bool APlayerCharacter::CanStand() const

{

FVector Start = GetActorLocation();

FVector End = Start + FVector(0.0f, 0.0f, 190.f);

FHitResult Hit;

FCollisionQueryParams CollisionParams;

CollisionParams.AddIgnoredActor(this);



return !GetWorld()->LineTraceSingleByChannel(Hit, Start, End, ECollisionChannel::ECC_Visibility, CollisionParams);

}

void APlayerCharacter::Prone()

{

UE_LOG(LogTemp, Warning, TEXT("Character Height: %f"), GetCapsuleComponent()->GetUnscaledCapsuleHalfHeight());

GetCapsuleComponent()->SetCapsuleHalfHeight(30.f, true);

GetMesh()->SetRelativeLocation(FVector(0.f, 0.f, -35.f));



GetCharacterMovement()->MaxWalkSpeed = ProneSpeed;

UE_LOG(LogTemp, Warning, TEXT("Proning!!"));

UE_LOG(LogTemp, Warning, TEXT("Character Height: %f"), GetCapsuleComponent()->GetUnscaledCapsuleHalfHeight());

}

void APlayerCharacter::UnProne()

{

GetCapsuleComponent()->SetCapsuleHalfHeight(93.f);

GetMesh()->SetRelativeLocation(FVector(0.f, 0.f, -95.f));

UE_LOG(LogTemp, Warning, TEXT("Unproning!!"));

}

Is there any other way to do it?
