Press CTRL+F and type there: "OnPlayerText"
You should find it.
Put this part there:
if( strcmp( text, "!website", true ) == 0 ) {
SendClientMessageToAll( 0xFFFF00, "www.blahblahblah.com" );
return 1;
}
Don't forget, you must have just one " if ( ... ( ... ) ... ) { " , the rest will be " else if ( ... ( ... ) ... ) { " .
Example:
public OnPlayerText(player, text[])
{
if( ... ( ... ) ... ) {
//your code
return 1;
}
else if ( ... ( ... ) ... ) {
//your code
return 1;
}
else if ( ... ( ... ) ... ) {
//your code
return 1;
}
return 1;
}
