Engine API reference
Verify a symbol exists
Checks that a class, function, or property really exists in your engine version before Dola uses it, to avoid invented APIs.

When to use it
Dola checks names during Blueprint and editor work; ask for it before C++ work or when you doubt an API from elsewhere.
Example prompts
Type requests like these in the Dola chat:
- Does UKismetSystemLibrary have LineTraceSingle?
- Is FVector::DistSquared2D available in 5.7?
What you need
- The Dola desktop app, signed in, with your Unreal project attached
Safety notes
- Read-only: it looks at your project and does not change it.
