Hi,

why does the following code set the invisible flag of the me entitiy?

my.emask |= ENABLE_SCAN; // that is the right syntax, is also in the manual.

INVISIBLE and ENABLE_SCAN set one bit of a long (32bit integer). In this case it is the 8. bit. This long have a name as every var, flags is one name and emask the other. There is also a flag2.

With set(my,ENABLE_SCAN) you set the 8. bit from the "flags" and not from "eflags", and that is the INVISIBLE one. Have a look at the define from set():
#define set(obj,flag) obj.flags |= (flag)

All because the "set(...)" function only changes the flags in
the 'my.flags' property, and ENABLE_SCAN belongs in the 'my.emask' property.

Ah thank you.
Someone should correct the line in the manual where stands:

my.ENABLE_DETECT = ON;

Because of this line I thought it's the flag var

my.ENABLE_DETECT = ON;
that is the old language c-script, all red marked lines in the manual is c-script,
my.emask |= ENABLE_DETECT;
all green marked is lite-c
