Syntax

UCLASS (Blueprintable, BlueprintType)  
class UFollowPathMode : public UBaseMovementMode

Remarks

FollowPathMode: This mode performs simple movement of the associated actor, attempting to interpolate through a series of locations. There are variety of settings that affect behavior, such as speed and looping.
