clean-shapes's Issues

Add pie and ring shapes

Rendering on iPhone SE 2nd Ed. broken (upstream)

Also tested on v2023.6; rendered results are broken for the test project.
Using latest runtime, built with Xcode 15.1.
Target device is iPhone SE 2nd generation, with iOS 16.1.2.

Attached is the result on iOS:

And the expected result rendered on PC:

Add offset to border of shape

Offset value for borders with positive numbers moving outwards and negative numbers moving inwards of the shape.

example:
.Border(thickness, offset, color, alpha)

CleanRing documentation uses radius/thickness when it should be inner/outer radius

CleanConvex wonkiness

Here's another thing I noticed

Border thickness is super inconsistent
Shape can break

Higher rounding and border thickness worsen the effects

Code for the above gif:

var _x = 100, _y = 200, _size = 50, _offset = sin(current_time / 500);
CleanConvex([_x - _size, _y - _size,    _x + _size + (_offset * _size), _y - _size - (_offset * _size),    _x + _size, _y + _size,    _x - _size, _y + _size]).Blend(c_orange, 1.0).Border(10, c_red, 1.0).Rounding(0).Draw();
_x += _size * 3;
CleanConvex([_x - _size, _y - _size,    _x + _size + (_offset * _size), _y - _size - (_offset * _size),    _x + _size, _y + _size,    _x - _size, _y + _size]).Blend(c_orange, 1.0).Border(30, c_red, 1.0).Rounding(0).Draw();
_x += _size * 3;
CleanConvex([_x - _size, _y - _size,    _x + _size + (_offset * _size), _y - _size - (_offset * _size),    _x + _size, _y + _size,    _x - _size, _y + _size]).Blend(c_orange, 1.0).Border(10, c_red, 1.0).Rounding(30).Draw();
_x += _size * 3;
CleanConvex([_x - _size, _y - _size,    _x + _size + (_offset * _size), _y - _size - (_offset * _size),    _x + _size, _y + _size,    _x - _size, _y + _size]).Blend(c_orange, 1.0).Border(30, c_red, 1.0).Rounding(30).Draw();

Rotated rectangles using .Blend4() are coloured incorrectly

Add ellipse drawing

Feather support

Rectangle borders are funky

Setting a border larger than or equal to the rounding value causes problems.

Unintuitive to draw a border-only ellipse

Minor note on CleanShapes, I have to do this to get a border-only ellipse:

    CleanEllipse(focused_node.x, focused_node.y, 120, 80)
        .Blend(c_black, 0)
        .Border(5, focused_color, 1)
        .Draw();

If you remove that Blend it just draws a solid ellipse (using the border color), which isn't what I'd expect. Not sure if this is a bug/fixable, just mentioning it

Add oriented box shape

Will be a wrapper for CleanConvex

Add dashed lines + polylines

Update wiki

Add vertex buffer output function for batches

Convex shapes cannot be drawn without specifying the blend array

Add regular n-gons + stars

Add gradient on Circle shape

It would be useful to be able to add a gradient (radial/four corner) on Circles too.

Add curve drawing functions

Either/both Beziér curves and splines

Dashed lines

.BlendExt() is inconvenient when used with splines

CleanLine thickness error

The .Thickness(pixels) function makes CleanLine much thinner than requested.

Add textured mode

Inspired by https://twitter.com/lucknknock/status/1370321166984962052?s=20

Rectangle rotation currently unsupported in jaggies mode

Add toggleable vertex ordering fix

Triangles and convex polygons require that their coordinate be defined in a clockwise fashion. Clean Shapes should support an "autofix" behaviour that solves this problem for the user.

Fix behaviour with matrices

Defining less colours than segments on a CleanSpline with .BlendExt throws error

I mentioned this in the pull request, the spline test room was crashing due to it.

Assuming x1, y1, etc. are set, the following code would compile:

CleanSpline([x1, y1, x2, y2, x3, y3, x4, y4, x5, y5], 6) // more segments than colours
.BlendExt([c_white, 1.0, c_yellow, 1.0, c_fuchsia, 1.0, c_aqua, 1.0, c_lime, 1.0])
.Draw();

But this would throw an ungraceful error:

CleanSpline([x1, y1, x2, y2, x3, y3, x4, y4, x5, y5], 5) // same amount or less segments than colours
.BlendExt([c_white, 1.0, c_yellow, 1.0, c_fuchsia, 1.0, c_aqua, 1.0, c_lime, 1.0])
.Draw();
