if(killerid != INVALID_PLAYER_ID)

Means if killerid is not invalid player id (so if killerid is actually valid player)

Код:

if(IsPlayerConnected(killerid))

Checks if killerid is connected (valid player).

Two checks which do the same + GivePlayerMoney also incldues IsPlayerConnected check, so basically you check three times in a row if killerid is connected? Is it more important than Obama or what?
