FMassCommandSwapTagsInternal

API > API/Runtime > API/Runtime/MassEntity

Atomically swaps one tag for another on entities. Removes TOld and adds TNew in a single composition change. Uses PushCommand for cross-chunk batching.

Example: // All entities in chunk: Context.Defer().SwapTags(Context.GetEntities()); // Single entity: Context.Defer().SwapTags(EntityHandle);

Supported types: FMassTag subtypes only (compile-time static_assert). Breakpoint support: No. Entity moves: 1 move (both tag changes applied together).
