Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Access none trying to read property

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" ?

It is a Player Controller class

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 ?

It didn't.
