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"

Find Item connected to Try Get Pawn Owner invalid on load

I am using the Find Item node connected to Try Get Pawn Owner in two separate blueprints (one animation blueprint and one character blueprint), which function correctly until the editor is restarted. At this point, an error is thrown up as the Find node 'accessing none' and the Find node must be replaced by pulling from TGPO node.

Everything functions fine after replacing the node, but breaks the BP on load, meaning my pawns are moving around in T-pose or not moving at all. Having to do this every time I open the project is getting slightly tiresome!

(Apologies if this is my mistake)

Have included ss' of both BP issues and which Find Item node type is selected alt textalt textalt text

Hi ElizeSinka,

If you take a look at some of our example AnimBPs (i.e. the Third Person Template Project), you'll see an IsValid check for every "Get Pawn Owner" check that is done. That's because the AnimBP Editor treats the viewport instance as running instance of the AnimBP itself. Because of this "Get Pawn Owner" will return "None" for the viewport instance, which is why you get Accessed None Errors.

These should still work in game just fine, but the IsValid check will keep those errors from occurring while editing.

If that doesn't fully answer your questions, let me know and we'll go from there.

Hi Matt!

Thank you for your reply; I in fact am using the IsValid node, sorry I should have included that in my screenshots, and the GetAllActors and FindItem node etc. are all being executed after the IsValid node has been. The FindItem node works seemingly consistently after replacing it, until I restart the project where it will throw up errors on load.

Hey ElizeSinka,

Can you send an example project showcasing this issue? You can PM me a download link on the UnrealSlackers Discord channel (see epic staff) or on the forums
