Just wanted to advertise this pack I released. It helps with the issue of melee traces missing some times.
What is happening is when you use any form of collision detection it is performed per-frame. So when an object, like a sword, is swung very fast it potentially moves over a distance greater than its own size in a frame. This leads to teleporting and skipping through objects without collision.
(This image shows the enhanced trace in action. The red traces are performed all in one frame due to the sword moving far in this frame.)
That is what this pack solves as it will fill the gap with traces of the same type, and will interpolate the position and rotation as well to be more accurate. So just use this pack, which is entirely blueprint made for easy modification, and now you can easily have more accurate melee collision.
(This is the same problem when a projectile flies too fast. This pack was designed with melee in mind but may work on projectiles as well if set up properly in the projectile BP.)
This pack is BP based and Trace based, opposed to collider volume based, to allow for more customization if needed and more available data since colliders don’t return hit data in most cases.
