Probably should have also asked for the PlayerControllerBase.cpp as well, sorry. Could you show that?

#23

sure

#include "PlayerControllerBase.h"




void APlayerControllerBase::SetPlayerEnabledState(bool SetPlayerEnabled)
{
    if (SetPlayerEnabled)
    {
        GetPawn()->EnableInput(this);
    }
    else
    {
        GetPawn()->DisableInput(this);
    }
    bShowMouseCursor = SetPlayerEnabled;

}
#24

Is line 11 of the PlayerControllerBase this?

GetPawn()->EnableInput(this);

Well that is implying GetPawn is returning nullptr which is odd. Or maybe it’s an old build and you previously did GetOwner by mistake (suggesting as more than one person did that)?

Could you try rebuilding?

#25

How should I rebuild it sorry

#26

Sorry I thought that was covered. In VS Code with Unreal closed

Ctrl + Shift + B > ProjectNameEditor Platform Development Rebuild.

Where platform is the platform you’re building for e.g. Win64. Be sure to choose the editor version.

I do that and it only brings up C/C++: cl.exe build active file. I can’t search for any others

#28

Are you sure you have the workspace open?

#29

Yeah I’m pretty sure Although I may have opened it differently

Doesn’t look like it. You should have

As well as the .code-workspace which I forgot to highlight. Do you not have that in your project directory?

#31

I think I managed to turn it into a workspace
Capture

#32

Well I see that you have a solution file. So if you open the solution in Community you can rebuild through that via Build > Rebuild.

#33

Ok right I’ll give it a go.

#34

Visual studio community?

#35

Double click the .sln file i n File Explorer.

#36

oh ok

#37

Alright, I rebuilt the .sln file

#38

And?

#39

Here is the log sorry for taking so long
