I'm creating an open polygon like so:
gfx.drawPolygon(table.unpack({10, 10, 60, 10, 60, 60}))
The documentation states:
If the polygon’s first and last points are coincident, the polygon will be considered closed.
I assumed that this meant the juxtaposition would be true, that non-coincident end points would leave it open, however the polygon is being drawn closed.
Is this my misunderstanding or is this a bug?
I think you're probably right that there is a bug lurking there, as this code:
local poly = playdate.geometry.polygon.new(10, 10, 60, 10, 60, 60)
gfx.drawPolygon(poly)
will produce:
I'll file a bug, but you should be able to use that workaround for now!
The points in the polygon are generated dynamically, so that won't be a workaround for me.
I fell back on generating a series of lines.
You can still create an intermediate polygon object from these dynamically generated points, no?
What do you mean by intermediate polygon? If that different to just drawing lines?
Something like this?
local poly = playdate.geometry.polygon.new(table.unpack({10, 10, 60, 10, 60, 60}))
gfx.drawPolygon(poly)
I see what you mean, I'll try that.
Yeah, my understanding from @dan was that the workaround is creating a polygon object and drawing that, instead of passing individual points directly to drawPolygon.
