UGameplayStatics::CancelAsyncLoading

function Engine Blueprint Since 4.0

#include "Kismet/GameplayStatics.h"

Access: public Specifiers: staticUFUNCTIONBlueprintCallable

Description

Cancels all currently queued asynchronous package loading requests. Used before a hard level transition to clear the async load queue and prevent stale loads from completing into the new world.

Caveats & Gotchas

• Cancellation is best-effort: packages that have already been fully read from disk may still complete loading even after this call. The cancel prevents new decompression and processing but cannot abort I/O already in flight.
• Any callbacks registered via LoadPackageAsync or similar APIs for the cancelled requests may never fire, or may fire with a failed status. Always guard callbacks against this.
• Calling this does not flush streaming levels managed by ULevelStreaming — use FlushLevelStreaming for that. CancelAsyncLoading targets the lower-level async package loader.

Signature
