Unreal Engine 4 Scripting with C++ Cookbook

Implementing a UInterface on an object

Ensure that you've followed the previous recipe in order to have a UInterface ready to be implemented.

How to do it...

1. Create a new Actor class using the Unreal Wizard, called SingleInterfaceActor.
2. Add IInterface—in this case, IMyInterface—to the public inheritance list for our new Actor class:

   class UE4COOKBOOK_API ASingleInterfaceActor : public AActor, public IMyInterface

3. Add an override declaration to the class for the IInterface function(s) that we wish to override:

   FStringGetTestName() override;

4. Implement the overridden function in the implementation file by adding the following code:

   FStringASingleInterfaceActor::GetTestName()
   {
     return IMyInterface::GetTestName();
   }

How it works...

1. C++ uses multiple inheritance ...
