Access none trying to read property

KittehBiscuit · July 25, 2016, 3:37pm

I am trying to make a mouselook top down view shooter. I have created this to make the player character look at the crosshair to shoot. Every single time i move the mouse at all, this error pops up. Any help will be greatly appreciated and I will upload my blueprint and the error code. The full error code is; “Blueprint Runtime Error: Accessed Non trying to read property CallFunc_K2_GetPawn_ReturnValue from Function 'ExecuteUberGraph_RotationControl”

The result is probably an easy fix but any help is appreciated massively. I am brand-new to using this engine.

Is this the pawns BP? If so try pulling a pin off target on rot and typing “self” ?

hi there. can you tell me what kind of classe is that blue print? is it a player controller, a pawn or otherthing?

Player Controller

I sometimes get this with a pawn, does it only happen at the start of play (the error). Pull off a pin from controlled pawn and type “is valid” then set it to rotate if valid. Did this work ?
