We have two view mode our my game:
1-Perspective
2-TopView
moving camera will be different in each mode so we decide to change between two input mapping contexts:
1-CameraPerspective_IMC
2-CameraTopView_IMC
we did it though this function:
void AVehicleController::EnableCameraTopViewEnhancedInput(bool bEnable)
{
if (UEnhancedInputLocalPlayerSubsystem* Subsystem = ULocalPlayer::GetSubsystem<UEnhancedInputLocalPlayerSubsystem>(this->GetLocalPlayer()))
{
if (InputComponent != nullptr)
{
if (!EnhancedInputManager)
{
EnhancedInputManager = NewObject<UNasirEnhancedInputManager>();
}
if (!EnhancedInputManager)
{
UE_LOG(LogNasir, Error, TEXT("EnhancedInputManager Is Null"));
}
else
{
{
if (bEnable)
{
Subsystem->RemoveMappingContext(EnhancedInputManager->CameraPerspective_IMC);
Subsystem->AddMappingContext(EnhancedInputManager->CameraTopView_IMC, 0);
}
else
{
Subsystem->RemoveMappingContext(EnhancedInputManager->CameraTopView_IMC);;
Subsystem->AddMappingContext(EnhancedInputManager->CameraPerspective_IMC, 0);
}
}
}
}
}
}
it only works well at the first 50-60 second and after that changing the IMC will cause this crash:

any idea?
