Confused about function parameter

[Grim_1 (Grim ヤ)]

Like if I have a function that is defined to take an int you cannot type foo(int) as a valid argument. I guess what you are saying is… because of the enum parameter something magical is happening to initialize a value.

Nothing magical at all. An enum is basically a type wrapped around an int but the type itself is ECollisionChannel and the value is ECollisionChannel::ECC_PhysicsBody. It is like calling foo(1) or foo(2) not like calling foo(int). Maybe read up on enums and it will all make sense.
