Im getting this errors and I have no idea how to solve them.
This occurred when I inserted the InputComponent line, but even when I erased the line the error still persists. This is awkward because I did the last lesson without any problems.
Any solutions? Because I’m Stuck 
.
Edit: I’m using the 4.17.2 version.
change line 31 and 33 to the following:
class UPhysicsComponent *PhysicsHandler = nullptr;
class UInputComponent *InputComponent = nullptr;
The “failed to produce item Project.dll”-error typcially means that you used something you haven’t included.
Normally you would have to include …/InputComponent.h, but it’s bad practice to use includes in headers,
so you can just “forward declare” them like I showed above.
It works, thank you for your help and attention.
