LineTraceSingleByChannel ECollisionChannel not working as Expected 4.13.2

Apparently using LineTraceSinglebyObject fixes your problems.

LineTraceSingleByChannel filter not working correctly

So, I’m trying to perform a line trace in some C++ code to detect walls, which must have the WorldStatic collision response. However, it seems that LineTraceSingleByChannel is invariably returning a collision with my player actor, despite having the filter set to WorldStatic and the player using Pawn collision response. Here’s the code I’m using: GetWorld()->LineTraceSingleByChannel(wallHit, GetActorLocation(), GetActorLocation() + (direction * 50), ECollisionChannel::ECC_WorldStatic) But thi…

LineTraceSingleByObjectType(TraceHitResult, startPos, endPos, FCollisionObjectQueryParams(collisionChannel), QueryParams);

instead of

LineTraceSingleByChannel(TraceHitResult, startPos, endPos, collisionChannel, QueryParams);

I tried it and it works much better. I’m not hitting my AI actors when I set the collision channel to ECC_WorldStatic
