pawn Код:

if(!strcmp(cmd, "/engine", true) ==0 || strcmp(cmd, "/e", true))

Just use either ! or == 0, not both, since they do the same thing.
And you need to do the same in the second strcmp as well.

pawn Код:

if(!strcmp(cmd, "/engine", true) || !strcmp(cmd, "/e", true))

There's OnPlayerTakeDamage and OnPlayerGiveDamage as well which would be just as good, but it's his decision what he wants.
