Casting to a UInterface implemented in native code
One advantage that UInterfaces provides you with as a developer is the ability to treat a collection of heterogeneous objects that implement a common interface as a collection of the same object, using Cast< >
to handle the conversion.
Note
Please note that this won't work if your class implements the interface through a Blueprint.
Getting ready
You should have a UInterface
, and an Actor
implementing the interface ready for this recipe.
Create a new game mode using the wizard within Unreal, or optionally, reuse a project and GameMode
from a previous recipe.
How to do it...
- Open your game mode's declaration, and add a new
UPROPERTY() macro
to it:UPROPERTY() TArray<IMyInterface*>MyInterfaceInstances;
