PlayerLookAtCallback not working

[Frontcannon]

I want to trigger a function when the player looks at a corpse, but the script doesn't want to compile and always puts out the 'Expected data type' error..

Code: (Select All)

void LookAtCorpses(string &in entity, 1)
{
    PlaySoundAtEntity("", "04_break02.snt", "Player", 3.0f, true);
}

The PlaySoundAt.. is just a filler to see if the Callback worked, but it doesn't.

The func name is in the PlayerLookAtCallback field in the editor's entity tab, the callback syntax is correct afaik. Now what is wrong?
