Without an idea of your knowledge of blueprint, guess a generic way could be: 1. One of the characters or a third class is needed to have a reference to all actors with the data to merge. 2. Iterate the references to [append](https://www.youtube.com/watch?v=OIngYuNKYc8) each to a new array or an existing one. 3. swap the indexes using [your favorite sorting algorithm](https://forums.unrealengine.com/t/sorting-algorithms-in-blueprints/1135992). And of course do all this inside a function. * * * If a third class is used there is also the option to get the array using an interface to avoid the include of the character class. * * * Here are some useful links: - [https://www.youtube.com/watch?v=RwbkvUEgCls](https://www.youtube.com/watch?v=RwbkvUEgCls) - [Array Nodes | Unreal Engine 4.27 Documentation](https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/Blueprints/UserGuide/Arrays/ArrayNodes/) - [Optimizing TArray Usage for Performance - Unreal Engine](https://www.unrealengine.com/en-US/blog/optimizing-tarray-usage-for-performance) * * * Hope it helps.
