(Unreal Engine 5.7.1)  
Motion Controller Component has blueprint useable “Get” methods inaccessible (protected) in C++

`UMotionControllerComponent* pMotionController;`  
`FVector linearVelocity;`  
`FRotator angularVelocity;`  
`pMotionController->GetLinearVelocity(linearVelocity);`  
`pMotionController->GetAngularVelocity(angularVelocity);`

> ‘UMotionControllerComponent::GetLinearVelocity’: cannot access protected member declared in class ‘UMotionControllerComponent’  
> ‘UMotionControllerComponent::GetAngularVelocity’: cannot access protected member declared in class ‘UMotionControllerComponent’

I can think of no reason these functions, which we can use freely in blueprints, can’t be used as  
public methods in C++.

There are a bunch of random functions that aren’t public for no discernable reason, or classes like AInfo which are explicitly disabled either in blueprints or in C++, so forums are full of obtuse solutions where we have to create redundant “Ex” or “My” classes to inherit an existing, otherwise perfectly fine class, to expose a single function or enable the class in blueprints, e.g.

`class UMotionControllerComponentEx : public UMotionControllerComponent {`  
`public:`  
` // No need to make BlueprintCallable since blueprints can just call GetLinearVelocity or GetRadialVelocity()`  
` void GetVelocities(FVector& linearVelocity, FRotator& angularVelocity)`  
` {`  
` // Now we can call protected methods.`  
` GetLinearVelocity(linearVelocity);`  
` GetAngularVelocity(angularVelocity);`  
` }`  
`};`

`// ... or `  
`UCLASS(Blueprintable) class AInfoActorEx : public AInfo {};`
