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"

If you check that the return value from Load Game from Slot is valid (just plug it into an Is Valid node) before casting it do you still get the crash. The The debug notes make me think a null reference is being returned by the load function, which causes a crash when you try to access it for the cast function.

I did that. Still get the same crash. so i think the game slot is valid alt text

Hello vyzor,

I have a few questions that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Can you reproduce this issue in a clean project?

  2. If so, could you provide a detailed list of steps to reproduce this issue on our end?

  3. Could you provide screen shots of all the blueprints involved?

  4. Was the a project that has been upgraded from an older version of the engine?

sorry for the delay on the answer.. the problem was not in that BP. but on the Spawn BP. alt text

in the picture you can see that the Spawn Actor is getting witch actor to spawn from an Array. now. this is the weird part. if i unplug the array it crashes. if i leave the array everything is okay! even though the array only has 1 Bp in it. But thanks for the help!
