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"

Projectile Going Through Walls

So my projectile, no matter what I do, always goes through walls, I tried to use the "on hit > destroy actor" idea (https://answers.unrealengine.com/sto...ecollision.png) but it didn't work either, while playing, it keeps adding actors when I fire and never destroying them, any ideas?

(I know this question is old, but I'm gonna answer it anyway...)

Have you tried enabling "continuous collision detection" on the projectile?

Continuous collision detection prevents small and/or fast objects from passing through walls.

(To enable it: navigate to the projectile's "details" tab, and under collision: check "Use CCD".)

CCD does not work for me when I tried it.

If the projectile is too fast, it may don't see the wall :

1000 m/s -> ~40m per tick so the wall is too small to be calculated

use linetrace for collision, this will detect your wall ;)
