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"

crashing with trace bluprint on weapon

Running this blueprint (or blueprints very similar to it as I've had to rebuild it manually a few times). The blueprint runs fine, and the traces execute and hit very cleanly, until I save everything and close the engine. At that time I get an error revolving around the weapon producing the traces. It is attached to a socket on my third person character. The biggest change to this version that has changed is that I am limiting the trace to when the parent says the weapon is being swung. Usually I just standby computer when I walk away, so I don't know which version of the blueprint started crashing on load, but I haven't be able to get a version with the bool from parent to work on loading engine. alt text

link text

A brief summary since the vector lines get a bit out of hand, the top row of traces runs from last_x/3 to current socket location, and the second row of traces runs diagonally from 2 current sockets. Also is there a better way to screenshot larger blueprints? The lines seemed to move as I was panning and matching the 3 together looks like a bit of a hack job.

I'm not sure what other information is relevant to this, let me know and I will add anything.

EDIT: oh, the debug type has been set to duration every time I've saved, closed, and crashed, this was just a quick rebuild for the post.

I should also add this is using blueprints on a c++ project.

Is there any easy work around for this in the mean time? Some way to get the variable status without casting perhaps?

I do not have a workaround for this issue at this time.

Okay, thank you for reply, I will do some fiddling and report back if I find anything.
