No.. You check 'if (pointer)' which checks if the value of the pointer is
or is not null.
If you clear the mob, the pointer would still point to memory, but the
memory pointed to be would be null, the check for that would be
if (*pointer)
Which dereferences the pointer, and checks the value pointed to by
pointer.
