Danger of LoadSynchronous

Example of why LoadSynchronous is very bad and shouldn’t be used in shipped builds (Thanks to Northstar)

Northstar

“Let’s say you’re loading a map async. It’s a big map and it’s taking a while. Then you call LoadSynchronous on a DA or something. Map load gets cancelled, DA blocks game thread to load, Map starts loading all over again but blocking the game thread”

In other words: “LoadSync halts all requests in the queue. They can’t resume async so SM handles this by sync loading them”

Filtering PDAs using tags Thanks to Snaps

• On PDA
  • Override GetAssetRegistryTags(Context)
  • Add tag to Context
• When searching:

FAssetRegistryModule& AssetRegistryModule = FModulemanager::LoadModuleChecked<FAssetRegistryModule>("AssetRegistry");
AssetRegistryModule.Get().GetAssetsByTagValues(Tags, OutArray);
