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"

Line trace through a character always returns false

Hi, I'm trying to use line trace by visibility channel through a character but the result is always false. See the screenshot.

Obviously the line pierces through the left character. Below is the collision preset for capsule componet of that character.

The "Line Trace by Channel" has the following set:

  • Trace Channel: Visibility

  • Trace Complex: false

  • Ignore Self: true

What am I doing wrong?

Hi Mate

Is this collision setup on Mesh or Collision capsule?

Like I stated above this is the collision preset for the capsule componet of the character.

hello trace visibility should be checked in the pawn collision presets. if you trace for visibility channel the other Actor need to block visibility channel :)

Update: sometimes editor bug when changing collision channels in Blueprint for actors already inside world try delete and drop again .

Have fun

You were right, I deleted my character from the level and added it again and it worked. Thank you.

It would be great if this is fixed.
