FMassCommandRemoveElement | Unreal Engine 5.8 Documentation

API > API/Runtime > API/Runtime/MassEntity

Removes a single element type from entities at runtime. Requires PushUniqueCommand — each call creates a separate command instance (no cross-call batching). Supports all element types including shared and const shared fragments.

When to use: when the element type is only known at runtime and you need to remove a single type. Prefer FMassCommandRemoveElements when types are known at compile time (better batching, single entity move).

Example: // Single entity: FMassCommandRemoveElement& Cmd = Context.Defer().PushUniqueCommand(FMyFragment::StaticStruct()); Cmd.Add(EntityHandle); // All entities in chunk: Cmd.Add(Context.GetEntities());

Supported types: all FMassElement subtypes (fragments, tags, shared, const shared, sparse). Breakpoint support: No (runtime types — use FMassCommandRemoveElements for breakpoints).
