I am currently using Unreal Engine 4.26. I have been following this tutorial to make a parkour game in Unreal.
I followed the tutorial exactly, and made a walk/jump/double jump game.
However, when I made the wall climbing system, Unreal started giving an error.
The wall climbing still works, but it shows this error when it ends:
Blueprint Runtime Error: "Accessed None trying to read property CallFunc_BreakHitResult_HitActor". Blueprint: Parkour_BP_Char Function: Execute Ubergraph Parkour BP Char Graph: EventGraph Node: Branch
It has hundreds of copies of that error in the message log.
I would provide my unreal file, but I don't know how.
Here is the double jump blueprint setup; Image 1 Image 2 Image 3
(Sorry about 3 images, it's a large setup.)
Does anyone know how I can solve the error?
Will edit question with more info if needed.
