 There is still a problem with this function: It can only have a single argument, otherwise we can not register
 it as a sweep at the time loop since we additionally need the BlockDataID of our field.
 One possibility would be to have a global variable where the BlockDataID is stored (very bad design, do not do that!),

+or we could use a construct from the standard library called std::bind().
 The last can transform a function pointer of a two-argument function to a function pointer of a one-argument function
 by keeping the second argument constant: It "binds" the second argument to a fixed value.
