if(sscanf(params, "us", ID, Type)) ( you forgot the "s" )

Also if(strcmp(Type, "on", true) == 0)
change to :

Код:

if(!strcmp(Type, "on", false))

and the off one to :

Код:

if(!strcmp(Type, "off", false))

Little edit : SetPlayerHealth(playerid, 100000000); change to : SetPlayerHealth(playerid, 0x7F800000); because 1000000000000000000000 isn't gonna save you from fall damage.
