Missing BlueprintReadWrite in FInputActionKeyMapping and FInputAxisKeyMapping

Development Programming & Scripting
1

The struct FInputActionKeyMapping in PlayerInput.h throws a warning when used in blueprint because the property ActionName doesn’t have the BlueprintReadWrite attirbute. Same issue with all properties of FInputAxisKeyMapping.

Steps to reproduce:

  • Create new blueprint
  • Add a variable of type InputActionKeyMapping
  • Fill variable using make InputActionKeyMapping

Is it safe to still use these and just ignore the warnings? So far my workaround to get rid of these warnings is to add C++ wrapper functions that return the action name or create these structs.

Hey DarthWayne-

The warning is there to remind people that the Action Name pin will be removed in the future and to adjust/update their blueprints accordingly. It is still safe to use, just keep in mind that the Action Name pin may not be available in a future engine version.

Cheers
