Invalid 'String' passed as container index of type 'Number'

How is x defined?

If it's a member variable, try something like this (change Number to whatever your actual value type is):

var x as Dictionary<String, Number> = { "a" => 1, "b" => 2 } as Dictionary<String, Number>;

If it's a local variable, try this:

var x = { "a" => 1, "b" => 2 } as Dictionary<String, Number>;

Thanks.

Type inference and checking in Monkey C seems quite incomplete and buggy.

This code fails to type check: `dc.fillPolygon([[dotX - 3, dotY], [dotX, dotY + 4], [dotX + 3, dotY]])` with this error: `Invalid '$.Toybox.Lang.Array<Any>' passed as parameter 1 of type '$.Toybox.Lang.Array<$.Toybox.Lang.Array<$.Toybox.Lang.Double or $.Toybox.Lang.Float or $.Toybox.Lang.Long or $.Toybox.Lang.Number>>'`.

and adding `as Lang.Array<Lang.Array<Lang.Numeric> >` does not fix it. I guess I have to add `as` to each element of the outer array?

I will just disable type checking again until it's implemented better.

Yep it's a pain.

It's worse than that as types nested more than 1 deep (e.g. Array<Array<Number>>) aren't recognized by the compiler/parser (although they're required for stuff like this). The workaround is to do a typedef. See my comment here.

    typedef ArrayOfNumbers as Array<Number>;
    function testFill(dc as Dc) {
        var hrx = 5;
        var y = 2;
        dc.fillPolygon(
            [
                [hrx - 3, y + 2] as Array<Number>,
                [hrx, y] as Array<Number>,
                [hrx + 3, y + 2] as Array<Number>,
                [hrx - 3, y + 2] as Array<Number>
            ] as Array<ArrayOfNumbers>
        );
    }
