Simple. Approved.
Beside that, why do you do SetEventInt with "index" ? That's not even in the
event itself according to the wiki ?
Also, concerning your "conflict" problem, you could try creating a public forward, to call just before you fire your event, or try to set the "attacker" value to something like -1337 (untested, just general ideas).
And if you were to update your plugin, I'd remove FCVAR_REPLICATED from the version ConVar, as this can produce error in the client's console.
