I get “Accessed None trying to read property of CallFunc_BreakHitResult_HitActor” Node: Branch Graph" even with a branch off the line trace node for my door blueprint. When you click on the magnifying glass on the error message the rightmost branch shows up in the BP_ThirdPersonCharacter blueprint e…

Ah. You’re doing this trace from inside the player? Have you tinkered with the player character at all?

Besides adding the T key open door functionality, and the E key functionality to enter and exit a vehicle no changes to the default unreal third person blueprint.

Yup, no idea, sorry. Love to know when you find out though…

I’m just setting this up with the default 3rd person char. And the only thing I can say so far, is it’s basically impossible to hit the door with the line trace, because the player’s in the way! :slight_smile:

Put a collision box on the door [image] and set it to ‘ignore only pawn’ [image]

I think the line trace begins from the follow camera and ignores the player because it never shows BP_ThirdPersonCharacter in the string you had me make earlier rather whats in front of the character. [doorerror5]

Correct. But I couldn’t get my door to work until I put that box around it to block the trace.

Yeah the door requires collision to open. My door has a simple box collision set up and ignore only pawn is now set. (Was set to block all previously) Still get the error though. [doorerror6]

The door frame is using use Complex as Simple collision not sure if that affects it in any way since both the frame and door are part of the same Door_BP blueprint.

Now I remember. That default door ( I had ) has no collision, duh… You’ll need to set that back to what it was. I’m out of ideas, sorry :frowning:

Custom door accessed none error and invisible in viewport but not in game
