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"

  • Have you been able to reproduce this in a clean project?

  • Try looking into the errors that are appearing in your log as well and fixing those up to see if that helps with the crash.

  • If you can reproduce the crash, can you provide steps to reproduce the issue in a clean, blank project?

I know it has something to do with the fact I've made child blueprint classes, of a custom blueprint which is parented to the Actor class, that calls a function of the parent class. I copied and the function from the parent class and when I went to paste any function I copied into one of the child classes the editor crashes and upon reloading the map it crashes as if the map were corrupted or something...

I'll try to reproduce it later in the week I have a vertical slice milestone to turn in tomorrow and I'm having to do the entire project over... Is there such thing as having "nested" blueprints?

If the project is crashing on launch, you can try deleting the Saved and Intermediate folders (make a backup if you'd like to keep the file backups stored in the Saved folder) and opening the project/map again. This may help.

Have you looked into using a child actor component? This basically allows you to add another blueprint to your current blueprint as a component.

I will definitely look into that..I just started using Blueprints. It's easy making references public so I can set them through the details panel but for things like setting the ref of a widget that's not physically in editor or another situation like specifying a particular actor out of 20 from a single class is still a little puzzling to me.

Let me know if the deleting the Saved and Intermediate folders helps.

If you could provide an example of what you are trying to accomplish, I would be able to point you in the right direction, or provide some documentation that will give you a starting point.
