Checking for collision when not moving.

Development Programming & Scripting C++

Hey, so I have this movement system for my top-down character.

		FHitResult Hit(1.f);
		RootComponent->MoveComponent(Movement, TargetRotation, true, &Hit);

		if (Hit.IsValidBlockingHit())
		{
			const FVector Normal2D = Hit.Normal.GetSafeNormal2D();
			const FVector Deflection = FVector::VectorPlaneProject(Movement, Normal2D) * (1.f - Hit.Time);
			RootComponent->MoveComponent(Deflection, TargetRotation, true);
		}

Which works great!

However, I also need to do a similar collision check like while the player is not moving.

Basically the player can be on a moving platform (through attachment, which doesn’t count as moving for the code above).
So I wish to do this type of deflection movement when the player is on a platform as well.
But I’m at a loss where to start to get a suitable vector. Any suggestions?
