Keyboard Localization Issue in Unreal Engine
Hello,
I have an issue that’s driving me crazy, and its keyboard localization for input handling.
I am a beginner in Unreal Engine (love it so far), so please go easy on me.
The Problem
Some countries have different keyboard layouts.
Problematic layouts are for example: QWERTZ, AZERTY, QZERTY, Dvorak, Colemak and more
Let’s take the number keys on top of the keyboard as an example. Here is a list of how the 1-0 keys are localized in some countries:
| Country | Key Layout |
|---|---|
| Czech | +ěščřžýáíé=´ |
| Slovak | +ľščťžýáíé=´ |
| Hungarian | 0'-.,§!"+%/= |
| Slovenian | +čščđžqwertz |
| Croatian | +čćžđšđžćč-' |
When using these localizations, Unreal Engine mappings for 1-0 keys stop working as expected.
Blueprint with Enhanced Input
- You have InputActions for your actions.
- You have an InputMappingContext with these actions set to keys.
- If you set an input action within the context to a key like
1, it does not work on localized keyboards.
C++ Key Binding
The same issue occurs with C++ key bindings. For example:
InputComponent->BindKey(EKeys::One, IE_Pressed, this, &AGamePlayerController::LogNumKey<1>());
This works with English keyboards but not with the localized variants mentioned above.
Possible (but not ideal) solution
There is an easy way to fix this using a plugin called Loonyware - Keyboard Layout-Independent Input. However, this is a paid plugin and adds another dependency to your project. I wish to avoid using it and fix it via native Unreal Engine functionality.
I have tried finding a solution for this issue, but I could not find any useful resources or information on the matter.
Please help me out. I am sure there must be a easy way to do this that I am missing.
Thank you
