I am trying to use it in a project, but I cannot figure out how to place a touch event listener to each of the icons/objects in the carousel, If someone could provide a quick example of how to do that I’d appreciate it.
Thank you

local NUM_ITEMS=20;
local radiusX= 200;
local radiusY= 40;
local centerX = 240;
local centerY = 160;
local speed = 0.05;
local perspective = 3;
local carousel = display.newGroup()
local icons = {}
local function zSort(myTable, myGroup)
table.sort(myTable,
function(a, b)
return a.depth < b.depth – depth is your custom field
end
)
for i = 1, #myTable do
myGroup:insert(myTable[i].img)
end
end
function Icon(i)
local this = {}
local icon = display.newImage(carousel, “images/icon”…i…".png")
this.angle = (i-1) * math.rad(360/NUM_ITEMS);
this.img = icon
return this
end
function update(event)
local icon
local sin = math.sin
local cos = math.cos
for i=1, NUM_ITEMS, 1 do

local img = icon.img
img.x = cos(icon.angle) * radiusX + centerX
img.y = sin(icon.angle) * radiusY + centerY
local s = (img.y - perspective) / (centerX + radiusY - perspective)
img.xScale = s*0.25
img.yScale = s*0.25
icon.angle = (icon.angle + speed) --%math.rad(360)
icon.depth = s
end
zSort(icons, carousel)
end
for i=1, NUM_ITEMS, 1 do
local icon = Icon(i)
icons[i] = icon
end
function onTouch(event)
if(event.phase==“moved”) then
speed = (event.x - centerX) / 2000;
end
end
Runtime:addEventListener(“enterFrame”,update)
Runtime:addEventListener(“touch”, onTouch)
