Hi! I’m trying to make a simple character just to test the input system and I’ve ran into some problems. Here’s what I’ve got.

PlayerCharacter.h

PlayerCharacter.cpp

The compiler error I get:

My findings:  
After I remove line 36 from PlayerCharacter.cpp the character compiles so my wild guess would be that that’s what causing issues but I’m unable to figure out why.

I found this thread that should be of use to you: [Why does BindKey cause Link error? - #2 by Pierdek](https://forums.unrealengine.com/t/why-does-bindkey-cause-link-error/35447/2).

It seems that you need to include some dependencies in your project.build.cs file, which is labeled as [YourProjectName.Build.cs] and should be found in your project’s root source folder.

In this file, there should be a section called PublicDependencyModuleNames.AddRange(new string[] {}); in this you should add ‘SlateCore’ and ‘Slate’ based on what this thread is saying. Here is an example of what mine looks like, as a reference.

```
  PublicDependencyModuleNames.AddRange(new string[] { "GameplayAbilities", "GameplayTags", "GameplayTasks", "Core", "CoreUObject", "Engine", "InputCore", "HeadMountedDisplay", "UMG", "Slate", "SlateCore", "AIModule"});

```

I hope this helps, and good luck 🙂
