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"

Using arrays, "is pending kill" error after i have removed element :/

So im trying to create a system where a varying amount of objects "orbitals" will rotate around another object "orbit tester 2". Orbit tester 2 has an array or orbitals.

alt text pressing the "E" key creates a new orbital and puts it in the array. pressing the "Q" key removes an orbital from the array and destroys it.

alt text the event tick function goes through the array and operates their movement accordingly.

alt text visually, when running everything is fine, nothing looks out of place and the behavior seems to work well. but, when i stop running im greeting with a whole bunch of errors regarding a "pending kill" :/

I cant work out how my logic has failed, is there something i should know about how arrays are handled in ue4?

At first i thought there was a problem with the logic attached to the "Q" key, but changing the order of the remove + destroy nodes just causes everything to break, and the orbitals to hang in the air and stop working :/

Did you happen to find a solution? I'm having a similar problem.

You should add a is valid node (Standard macro) when you try to acces something in the array. So after a get node use this macro and everything should work without any errors. :D
