When i was scrolling the gooey dynamic list, text variables are scrolled successfully but the images not scrolled successfully.


please help me ,

local LISTITEM_SELECTED = hash("blue_button04")
local LISTITEM_PRESSED = hash("blue_button04")
local LISTITEM = hash("blue_button04")

local function update_listitem(list, item)
local pos = gui.get_position(item.root)
if item.index == list.selected_item then
	pos.x = 0
	gui.play_flipbook(item.root, LISTITEM)
elseif item.index == list.pressed_item then
	pos.x = 0
	gui.play_flipbook(item.root, LISTITEM)
elseif item.index == list.over_item_now then
	pos.x = 0
	gui.play_flipbook(item.root, LISTITEM)
elseif item.index == list.out_item_now then
	pos.x = 0
	gui.play_flipbook(item.root, LISTITEM)
elseif item.index ~= list.over_item then
	pos.x = 0
	gui.play_flipbook(item.root, LISTITEM)
end
  gui.set_position(item.root, pos)
end

local function update_dynamic_list(list)
for _,item in ipairs(list.items) do
	update_listitem(list, item)
	local tempData = item.data; 
	
	local imgurl = tempData.player_photo;
	if imgurl then		
		gui.set_text(item.nodes[hash(list.id .. "/listitem_text")], tostring(tempData.player_name or "-"))	
		gui.set_text(item.nodes[hash(list.id .. "/place")], tostring(tempData.rank or "-"))
		gui.set_text(item.nodes[hash(list.id .. "/points")], tostring(tempData.score or "-"))
		load_and_set_texture(imgurl, item.nodes[hash(list.id .. "/profilepic")])
	else

		gui.set_texture(node, texture_id)
	else
		print("Unable to create texture",url)

The dynamic list reuses nodes. Do you update the images when the list is scrolled?

Iā€™m thinking that the problem is that you load the images asynchronously over http and if you do this while scrolling then the loaded image is likely not set on the correct listitem.
