Hey everyone! 
Just wanted to share a quick solution to a frustrating issue I kept running into as a new UE developer.
Problem: Getting “Accessed None” errors when trying to reference objects in Blueprints, especially when calling functions on actors that might not exist yet.
Simple Solution: Always use “Is Valid” node before accessing any object reference!
Instead of directly calling functions on your object reference, add an “Is Valid” check first. This prevents the crash and makes your code much more stable.
Example:
- Before: PlayerReference → Set Health
- After: PlayerReference → Is Valid → (True) Set Health
This saved me hours of debugging time. Hope it helps other beginners avoid the same headache!
