[Graphics] How about text, polygons, and arcs?

If anyone hasn’t made their own arc function, here’s a deadly simple one.


--# Main
-- arc

-- Use this function to perform your initial setup
function setup()
    ar = arc(WIDTH/2,HEIGHT/2,200,150,0,180)
    et=0
end

function touched(t)
    fill(t.x,(t.y*t.x)/HEIGHT,t.x-t.y)
    et=et+0.05
    ar= arc(WIDTH/2,HEIGHT/2,200,math.sin(et)*80+110,0,(math.deg(math.atan2(t.y-HEIGHT/2,t.x-WIDTH/2))))
end
-- r = radius, mr = radius of inner arc, ang1, ang2 = start/end angles of arc.
function arc(x,y,r,mr,ang1,ang2)
    local arcshader = shader("Patterns:Arc")
    local minr = (mr/r)/2
    local m = mesh()
    m.shader = arcshader
    m.shader.a1 = math.rad(ang1)
    m.shader.a2 = math.rad(ang2)
    local col = color(fill())
    m.shader.color = vec4(col.r/255,col.g/255,col.b/255,col.a/255)
    m.shader.size = minr
    local rct = m:addRect(x,y,r,r,0)
    return m
end
function draw()
    background(40, 40, 50)
    ar:draw()
end
