Sure, dude. There's a working idea with example code posted in this thread that includes pretty much everything you need, and also descriptions of an alternative implementation with quads. You should now try to adapt one of those ideas, and come back when you have more questions.
I already wrote that I tried to create this thing for about four days. I tried several ideas, and upper one i tried too.grump wrote: ↑Tue Sep 12, 2017 3:55 pmSure, dude.

But that isn't really a questionThe most hardest part in my opinion is actually getting these digits work by turn.
For counter wheel I use ImageFont and canvas.
Code: Select all
meter = {}
meter.__index = meter
function meter:new(font, cells, init_value, speed)
local o = {}
o.font = font or love.graphics.newFont(32)
o.width = o.font:getWidth'0'
o.height = o.font:getHeight()
o.cells = cells
o.value = init_value or 0
o.actualValue = o.value
o.speed = speed or 7
o.cell = {}
o.canvas = love.graphics.newCanvas(o.width, o.height * 11)
o.canvass = love.graphics.newCanvas(o.width*o.cells*2, o.height)
love.graphics.setCanvas(o.canvas)
local oldf = love.graphics.getFont()
love.graphics.setFont(o.font)
for i = 0, 10 do
love.graphics.print(i%10, 0, i * o.height)
end
love.graphics.setFont(oldf)
love.graphics.setCanvas()
for i = 1, cells do
o.cell[i] = {value = o.value, shift = o.value*o.height, setted = false}
end
return setmetatable(o, self)
end
function meter:__add(v)
self.value = self.value + v
return self
end
function meter:__sub(v)
self.value = self.value - v
return self
end
function meter:set(v)
self.value = v
return self
end
function meter:update(dt)
if self.actualValue < self.value then
self.actualValue = self.actualValue + self.speed * dt
if self.actualValue >= self.value then self.actualValue = self.value end
elseif self.actualValue > self.value then
self.actualValue = self.actualValue - self.speed * dt
if self.actualValue <= self.value then self.actualValue = self.value end
end
for i, v in ipairs(self.cell) do
local val = self.actualValue/(10^(self.cells - i))
val = math.floor(val)
val = val * self.height
if v.setted == false then
v.shift = val
v.setted = true
end
if val > v.shift then
v.shift = v.shift + self.speed * self.height * dt
if v.shift > val then v.shift = val end
elseif val < v.shift then
v.shift = v.shift - self.speed * self.height * dt
if v.shift < val then v.shift = val end
end
end
love.graphics.setCanvas(self.canvass)
love.graphics.clear()
for i, v in ipairs(self.cell) do
love.graphics.draw(self.canvas, (i-1) * (self.width + 1), -( v.shift % (10 * self.height)))
end
love.graphics.setCanvas()
end
function meter:draw(x, y)
love.graphics.draw(self.canvass, x, y)
end
