TEntityRange | Unreal Engine 5.7 Documentation

API > API/Runtime > API/Runtime/MovieScene

Variadic template representing a contiguous range of entities with a specific set of components

The template parameters define each component type by index, whose constness should match the read/write semantics of the accessor. For example, an entity with a float, int and bool component, accessed read-only should be represented by a TEntityRange. If one wished to write to all the float components, we would require a TEntityRange etc
