The c++ component is not visible

Kimbab · February 12, 2024, 7:52am

I’ve added a c++ component, but I can’t see it through Add. Why?

Both grabber and mover belong to the Unreal Engine folder I ran. Why isn’t it coming out? It came out well at first, but it started not coming out at some point.

DanM · February 12, 2024, 1:33pm

Could you show the Mover files please?

Could you show CryptRaiderCharacter.cpp and highlight line 14, please?

Kimbab · February 13, 2024, 10:34am

DanM · February 13, 2024, 11:13am

What files do you have in Public/Private?

Kimbab · February 13, 2024, 11:32am

There is nothing in Public and Private.

DanM · February 13, 2024, 11:34am

Could you do a CTRL + F and search for LogTemplateCharacter and show the results?

Kimbab · February 13, 2024, 11:36am

DanM · February 13, 2024, 11:59am

Sorry, use Ctrl + Shift + F to search your whole workspace. The error says that log category is defined twice, so you have it defined once in that character.cpp and presumably somewhere else.

(You’ve also added that text to line 8 which you would need to remove)

Kimbab · February 13, 2024, 12:04pm

I deleted line 8.

DanM · February 13, 2024, 12:34pm

I didn’t mean delete line 8, I meant delete the LogTemplateCharacter bit you had at the end.

There doesn’t appear to be multiple definitions by the looks of. Have you tried a rebuild? You can do that by deleting the Binaries and Intermediate folders and then attempting to open the project.

Kimbab · February 13, 2024, 12:37pm

Are you saying to delete LogTemplateCharacter after line 8? I will delete it.

DanM · February 13, 2024, 12:40pm

In the screenshot I mentioned you had

#include "..."
#include "header.h"LogTemplateCharacter
#include "..."
....

I’m saying to remove that extraneous bit at the end.

Kimbab · February 13, 2024, 12:43pm

Delete Binaries and Intermediate folders. I’ll try that, too

Kimbab · February 13, 2024, 2:29pm

The issue has been resolved. Thank you so much. I’m curious about how this error occurred in addition, could you please let me know?

DanM · February 13, 2024, 5:20pm

Usually when you build you only compile files that have changed and reuse previous compiled code for what didn’t. Deleting those folders deletes all compiled and generated code so you can build from scratch.

So it was likely a result from reusing an old compiled file which should have been recompiled.
