Setting a Decal

Help and Feedback Scripting Support
#1

I’ve been making a command to set a block’s decal. I’ve came across an issue that I’ve never encountered. The decal would not appear as the image I set in the args[1] (238316631), but when I set the image to my username, it appears. Can anyone help me with this issue?

function module.init(player, args)
        -- just imagine args[1] being a player's username OR a decal ID

I tried testing you script, but it still had the same outcome. It didn’t show the decal image. But when I change the decal to the id, it changes…

Try this with something like the decal argument:

Because look

whether args[1] is a numeric asset ID or a username. Here are the changed lines:

Original: yours

local imageProperty = "rbxassetid://" .. args[1]

Updated: to see this

local imageProperty = nil
if tonumber(args[1]) then
    local ProductInfo = MarketPlaceService:GetProductInfo(tonumber(args[1]))
    if ProductInfo and ProductInfo.AssetTypeId == 13 then
        imageProperty = "rbxassetid://" .. args[1]
    end
else
    local userId = game.Players:GetUserIdFromNameAsync(args[1])
    if userId then
        local imageContent = game.Players:GetUserThumbnailAsync(userId, Enum.ThumbnailType.AvatarBust, Enum.ThumbnailSize.Size420x420)
        imageProperty = imageContent
    end
end

That still did not work unfortunately.
