Random functions/classes #3: Cool text effect

Created a text effect that you sometimes see in movies (I don’t know if it has a name)

--# Main

function setup() 
    num = {"1","2","3","4","5","6","7","8","9"}
    start = false
    parameter.text("string", function(n) txt=n end)
    parameter.action("Start_Effect",function() e=Effect(txt) end)
end

function draw()
    background(0)
    if start then
        e:draw()
    end
end


--# Effect
Effect = class()

function Effect:init(txt)
    start=true
    self.t = string.upper(txt)
    self.letters = {}
    self.timer = 0
    for i=1,string.len(self.t) do
        self.letters[i] = string.sub(self.t,i,i)
    end
end

function Effect:draw()
    fill(42, 78, 31, 255)
    font("AmericanTypewriter-Bold")
    fontSize(20)
    self.timer = self.timer + 1
    for a,b in pairs(self.letters) do
        if self.timer>15*a then
            text(b,a*18+200,HEIGHT/2)
        elseif b~=" " then
            text(num[math.random(#num)],a*18+200,HEIGHT/2)
        end
    end
end

Neat. I believe this is the same effect as in CoD Black Ops :slight_smile:
