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 to recompile a parent class every time I open unreal

Hello there !

A random bug just appears in our project and we didn't find any solution yet :

alt text

Error This blueprint (self) is not a TRASHCLASS_BaseWeapon_182, therefore ' Target ' must have a connection.

This error disappears if I recompile the parent class but come over with the next start of the engine. I can provide you my project if you need it. I'm in 4.12.5

Thanks in advance for any help !

Product Version: UE 4.12

Can you handle this event without calling Parent event? As much I can remember event overrides in blueprints automatically calls parent's event. At least it described in properties on this event node.
Specifically about this error: I have no idea why is this happening, when this error was bothering me I haven't found any solution, it's just gone by itself as I updated to 4.12.
