Could you expand on that? You also have a box collision on the enemy character and can’t get it triggered? If so, would you mind sharing a screenshot showcasing how you handle that as well? If you don’t handle it yet, you’ll need to get the On Component Begin Overlap (Box) node and check if it overlaps the player character the same way.
Btw, if the two characters cannot go through each other, their capsule components will never overlap. You can use the On Component Hit node to check if they hit each other tho. (Keep in mind that in order for that to work, both components should generate hit events.)
Or, you can keep your current setup and add a collision (sphere, box, capsule) to the player character that extends out if its capsule component, and that way the enemy will be able to detect the player.
