Hello,

I am new to OpenSCAD and functional programming, so bear with me.

Is it possible to pass a parameter to a module using the children() feature?

module test(which)
{
echo(which);
}

module main()
{
children(0)(1);  // error here
children(0,2);    // and here
}

main()
{
test();
}

This doesn’t work, but should illustrate what I’m trying to do. An alternate approach that does work, but isn’t quite what I want:

module test(which)
{
echo(which);
}

module main()
{
children(0);
children(1);
}

main()
{
test(0);
test(1);
}

Thanks,
Mark

Thanks for the tip.  I expanded your example slightly to do what I needed.

module foo() {
if ($i == 1)
echo("This is foo() level 1.");
else
echo("This is foo() not level one.");
}

module bar() {
echo(str("bar ", $i));
}

module main() {
children(0, $i = 1);
children(0, $i = 2);
children(1, $i = 1);
children(1, $i = 2);
}

main() {
foo();
bar();
}
