TSoftObjectPtr::ResetWeakPtr

function CoreUObject Since 4.17

#include "UObject/SoftObjectPtr.h"

Access: public Specifiers: inline

Description

Clears only the internal weak object pointer cache without touching the stored soft object path, forcing the next Get() call to re-resolve the path from scratch.

Caveats & Gotchas

• The path is preserved — IsPending() returns true after this call if the path is non-empty and the object is not currently in memory, making it useful for invalidation without data loss.
• In a PIE (Play-In-Editor) session, Get() bypasses the cache entirely and always resolves via the path, so calling ResetWeakPtr in PIE has no observable effect on Get() behavior.

Signature

UE_FORCEINLINE_HINT void ResetWeakPtr()

Return Type

void

Example

Forcing a re-resolve after a rename C++

// Object was renamed/redirected; path still valid but cached ptr is stale
for (TSoftObjectPtr<UDataAsset>& Ref : AllDataAssets)
{
    Ref.ResetWeakPtr();
    // Next call to Ref.Get() will resolve fresh from the path
}
