"illegal operand" error

[Kostatus]

The following code worked perfectly fine until i modified an unrelated part
of the program:
this->dungArea[x][y].mBlocked =
mioS.mio_dungArea[x][y].mFlags & isBlocked;

after that i started getting the error message:
error C2297: '&' : illegal, right operand has type 'bool (__thiscall
cDungeon::*)(int,int)'
Also,
if(this->dungArea[x][y].mBlocked)
mioS.mio_dungArea[x][y].mFlags |= isBlocked;

stopped working with the same kind of error message:
error C2297: '|=' : illegal, right operand has type 'bool (__thiscall
cDungeon::*)(int,int)'

Can anyone help me fix this?

Looks to me like isBlocked has been defined to be a pointer to a member
function of class cDungeon. Evidently, you can't use such pointers in
conjunction with the & operator.

Looks to me like isBlocked is not a variable, but a function, so the
compiler converts it into a pointer to it and gives it to the
operator&. Maybe you wanted to call the function instead? So you
probably wanted:

this->dungArea[x][y].mBlocked =
mioS.mio_dungArea[x][y].mFlags & isBlocked();
