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"

It seems your ball is affecting navmesh, and it doesn't sound like it's what you need. Just go to your ball BP, select static mesh component and tick of Can Ever Affect Navigation. This should do it :)

Movement or affecting navmesh problem? Screenshots always help. Or a repro project.

I am having the same problem. I followed some AI tutorials, but the enemy AI ball never seems to want to move. I followed your tip and unchecked the Can Ever Effect Navigation and that seemed to fix the navmesh problem, but the Enemy AI ball still won't move. Everything is straight from the template. In my enemy blueprint attached, when running the project, the OnSeePawn even triggers everything right, just no movement.alt text
