I’m at the end of the “Dependency Injection” lesson, I pick up the gargoyle, place it in the secret nook and nothing happens. I don’t know how to troubleshoot this, this project has been incredibly difficult and way over my head, sorry in advance. Here’s what I’ve tried and I’ll post relevant info below:
- Refreshing VSC in UE
- Rebuilding in VSC and relaunching UE
- Crying
- Reviewing the lesson resource code and ensuring they match.
My gargoyle and BP_SecretWall Trigger have the Acceptable Actor Tag ‘Unlock1’, I’ve tried removing and re-adding these, not sure how these are supposed to be configured.
