Watchmaker scroll text lua script

V1.11

(changes: scrolls smoother)

This script will scroll text. It returns a string that consists of the scrolled text.  It can scroll any number of texts just call it from the text field.

Call with:

var_textScroll("texthere", integer space to use, integer scroll rate,{dss})

E. G.

var_textScroll("some long bit of text", 6,1,{dss})

The {dss} at the end makes watchmaker update it each tick.

1 is the speed of scrolling. It will scroll faster in the wm emulator than the watch.  Higher is faster. 0.5 is slower

6 is how many characters to use


--text scroller: put this function in your main watchface script

--text scroller
var_runTime = {}

function var_textScroll(myText,space,interval)

var_runTime[myText] = var_runTime[myText] or 0
var_runTime[myText] = var_runTime[myText] + 1

local start
local myEnd

if not interval then interval = 1 end

local length= string.len(myText)

--dont scroll
if length <= space then return myText end

local runningTime = var_runTime[myText]

start = ((runningTime) % (length/interval)) * interval

myEnd = start + space

local text = string.sub(myText, start, myEnd)

if myEnd > length then
text = string.sub(text.."..."..myText, 1,space)
end

return text

 end
