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"

[Bug] Debug trace lines never disappear from viewport

Build CL1627304 - K:/TURE/Rocket_CL1627304

Specs Windows 7 Professional English, i7-3770K, 32GB RAM, GTX670 4GB driver 306.23 , UAC off

Description I added a capsule trace and enabled Draw Debug. That got me some red and green spheres, but upon moving the blue print actor in the level it kept drawing more spheres. Disconnecting/deleting the trace did not remove the spheres from the viewport. I had to restart the editor to get rid of them. Likewise with line traces. Also, after disabling Draw Debug, it often still continues to draw debug lines anyhow.

Repro Add a trace to BP, enable debug, place in level, move it around some. (I've been using user construction for it).alt text

Results Get spammed with ever lasting debug lines

Expected Some way of getting rid of the lines/time limit.

You can use 'flushpersistentdebuglines' in console to clear them

That works in the console (in 4.18) but not if you "exec console command" in a blueprint for some reason.

Hi Sjoerd,

I am attempting to reproduce this issue, but having some difficulties. Could you please show me a screenshot of the blueprint's script? This will help greatly.

Thank you,

Alexander

Any news? I can still do this in 4.11 preview 7. I have a trace in the consturct with debug on persistent, so of course it won't go away, but there should be a way to make them go away since they can get out of hand (move the actor around and I have a ton of red and green lines everywhere) and the only way I know how to remove them is to change the map.

Now you're probably going to say "well then don't put it on persistent" but I do want to see them... and putting it on For Duration may not be enough time to look at them all and do what I need to do.
