These settings can be found under Project Settings in the Edit dropdown menu. - We will need an Action Mapping to set up our particle-system toggle, two Axis Mappings to move our Pawn, and one more Axis Mapping to turn our Pawn. image  - // Make sure that everything is still valid, and that we are allowed to move. if (!PawnOwner || !UpdatedComponent || ShouldSkipUpdate(DeltaTime)) { return; } - There are more features included in Pawn Movement Components that are worthy of examination, but they are not needed for the scope of this tutorial. Looking at other classes, such as Floating Pawn Movement, Spectator Pawn Movement, or Character Movement Component, could provide additional usage examples and ideas. - Be sure that the last header file included is the one ending with "generated.h"; you can encounter compiler errors if it is not.
