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"

Can Line trace hit a particle?

the particles (custom mesh, ring shaped and scaling up over time) are emitted by the player's pawn (spawn attached), and I need to determine if one of those particles is present at a specific point. I have tried line trace by channel and by object with all the combination of settings I could, but they seem to not be able to detect a hit against a particle. It works detecting a hit against a static mesh component, but it doesnt seem to be able to spot particles. alt text I also tried to change the particles material to opaque (they are supposed to be additive) and I tried to add a collision to the particle mesh, and made sure particles collisions are active

can anyone think at a solution?

alternatively: could a blueprint sample the color value of a texture at a specific UV coord?
