New version after 4 months
Nothing particularly new here, just a dozen or so fairly minor tweaks and bugfixes. Perhaps the most noticeable one is that I swapped the position of the copy and paste buttons in the menu. I found myself fat-fingering the 'clear' button on my phone when I meant to 'paste'. Now I try to alternate buttons that don't modify the text with buttons that do, which provides a little more of a buffer for destructive changes. Still doesn't entirely eliminate fat-fingering; I'm tempted sometimes to add confirmation buttons.
Anyways, that hopefully gives you a sense for the scale of changes in this version.
While there's nothing major here, I've been streamlining the code behind the scenes, and enough of that sort of thing accumulated that I started feeling some pressure to put out a new version. So there's some chance I've introduced a regression in this release. Please let me know if you spot anything amiss.
Today's programs to play with are some silly variations on a theme I made a few weeks ago (inspired by a uxn program, IIRC).
Version 1
x, y = 512, 0 color(1,0,1, 0.2) repeat line(x,0, 0,y) x = x-8 y = y+8 until x <= 0
Version 2 (animated)
n = min(Safe_width, Safe_height-Menu_bottom) x1, y1, x2, y2 = n, 0, 0, 0 d = 8 dx1, dy1, dx2, dy2 = -d, 0, 0, d history = {} nlines = 30 function car.draw() color(1,0,1, 0.2) for i=1,#history do local x1, y1, x2, y2 = unpack(history[i]) line(x1,Menu_bottom+y1, x2,Menu_bottom+y2) end end function car.update() x1, y1, x2, y2 = x1+dx1, y1+dy1, x2+dx2, y2+dy2 table.insert(history, {x1, y1, x2, y2}) if #history > nlines then table.remove(history, 1) end if x1 < 0 then dx1, dy1, dx2, dy2 = 0, d, d, 0 x1, y2 = 0, n elseif y1 > n then dx1, dy1, dx2, dy2 = d, 0, 0, -d x2, y1 = n, n elseif x1 > n then dx1, dy1, dx2, dy2 = 0, -d, -d, 0 x1, y2 = n, 0 elseif y1 < 0 then dx1, dy1, dx2, dy2 = -d, 0, 0, d x2, y1 = 0, 0 end end
Version 3 (interactive)
widgets = {} n = Safe_width dx, dy = 8, 8 function dx_slider() local x0,x1 = 104,228 local lo,hi = 4,128 local x = dx+100 local y, w,h = 86, 20,20 local selected = false local draw = function() color(0,0,1) line(x0,y, x1,y) rect('fill', x-w/2, y-h/2, w,h) end local ispress = function(x2,y2) return x2 >= x-w/2 and x2 <= x+w/2 and y2 >= y-h/2 and y2 <= y+h/2 end local press = function() selected = true end local update = function(x2,y2) if selected then x = min(max(x2, x0), x1) dx = x - 100 end end local release = function() selected = false end return {draw=draw, ispress=ispress, press=press, update=update, release=release} end widgets.dx_slider = dx_slider() function dy_slider() local y0, y1 = 104, 228 local lo, hi = 4, 128 local y = dy + 100 local x, w,h = 86, 20,20 local selected = false local draw = function() color(0,0,1) line(x,y0, x,y1) rect('fill', x-w/2, y-h/2, w,h) end local ispress = function(x2,y2) return x2 >= x-w/2 and x2 <= x+w/2 and y2 >= y-h/2 and y2 <= y+h/2 end local press = function() selected = true end local update = function(x2,y2) if selected then y = min(max(y2, y0), y1) dy = y - 100 end end local release = function() selected = false end return {draw=draw, ispress=ispress, press=press, update=update, release=release} end widgets.dy_slider = dy_slider() function car.draw() x, y = n, Menu_bottom color(1,0,1, 0.2) repeat line(x,Menu_bottom, 0,y) x = x - dx y = y + dy until x <= 0 for name,w in pairs(widgets) do w.draw() end end function car.mousepressed(x,y, b) for name,w in pairs(widgets) do if w.ispress(x,y) then return w.press() end end end function car.update(dt) for name,w in pairs(widgets) do if w.update then w.update(App.mouse_x(), App.mouse_y()) end end end function car.mousereleased(x,y, b) for name,w in pairs(widgets) do if w.release then w.release() end end end
If you try pasting any of these programs into Lua Carousel, remember to first run the abbreviations on one of the example screens. Or if you've deleted that screen, here are the abbreviations I used in this post:
g = love.graphics line = g.line rect = g.rectangle color = g.setColor min, max = math.min, math.max
