How can i make a script that changes ClickDetector cursor icon for all ClickDetectors?

Hello Alexeeii,

The function that will be shown below searches everywhere in an entity, including its children, and it's children's children, and so on, for example, workspace. I like to think of it as a "deep search".

function Search(ItemToSearch)
    for i, v in pairs(ItemToSearch:GetChildren()) do
        if v:IsA("Part") then
            v.BrickColor = "Really red"
        end
        Search(v) --This repeats the search on the children of the children so it allows one to infinitely search through children of children, and their children, and their children, and so on.
    end
end)
--This would make every part that exists somewhere inside ItemToSearch turn red.

Then you'd use the function of whatever you'd like to "deep search". For example,

Search(workspace)
--This would make all parts in the workspace red, no matter where they are in the workspace.

In your case, you'd like to do things with all ClickDetectors in the workspace. So, your code would look something like this:

local icon = "rbxassetid://878096274"
local icon2 = "rbxassetid://878076293"
function Search(ItemToSearch)
    for i, v in pairs(ItemToSearch:GetChildren()) do
        if v:IsA("ClickDetector") then
            v.MouseHoverEnter:connect(function(Player)
                local Mouse = Player:GetMouse()
                Mouse.Icon = icon
            end)
            v.MouseHoverLeave:connect(function(Player)
                local Mouse = Player:GetMouse()
                Mouse.Icon = icon2
            end)
        end
        Search(v) 
    end
end

Search(workspace)
