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"

Pin connections silently break.

In case you change a variable type from one class ref to another class ref blueprint pin connections working on this class ref variable. This will lead to silent bugs which are not catched by the blueprint compiler. Those disconnected bugs are hard to detect.

The expected behavior would be to not break pins and instead issue compiler errors which have to be fixed.

If you change a variable type to a non compatible one it will break because it can't connect in the first place.

I know this and this is exactly the point. It should simply not break and instead issue compiler errors

You get a compile error where the pins are broken though.

This is not true in any case. It would only be true for reference pins. And another disadvantage is that you have to figure out on your own which pins broke and what is the output->input relation.
