Accessed None trying to read property. How can I solve this?

Thats because you’re playing in editor. Run the project in Standalone and you wont get those errors. This is a normal function and wont mess up your project.

Weeks ago I managed to get an AI working so that it would hear my footsteps and investigate, by following [this][1] tutorial. Earlier today I tried to add a door opening mechanic to the same AI and inadvertently messed up most of the AI’s code. I was able to revive most of the AI’s functionality but the hearing mechanic is broken. Not only that but for every step the player takes an Accessed None error.

Any idea how to stop these errors? It says it has something to do with the “Set Value As Vector” node but I can’t seem to see why. I followed the tutorial exactly. I’m still relatively new to UE4, so it may be (and hopefully is) something small, simple, and stupid.

Thanks in advance.

Oh Jesus, thank you so much! I feel so idiotic now.

No worries! I’ve been there. lol
