How to Update :GetChildren()

Help and Feedback Scripting Support
#1

So whenever I pick up an Item, I can’t hover over the item.
how would I update the :GetChildren() to check if there’s
a new Item which is inside the Holder?

The issue is, whenever I hover over the New Item it doesn’t show the information I want from print()

I tried adding a while wait(1) do which isn’t even good, but still didn’t work.

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local Fruits = require(ReplicatedStorage:WaitForChild("Fruits"))

local Holder = script.Parent

for Name, Fruit in pairs(Fruits) do
    for _,v in pairs(Holder:GetChildren()) do    
        if v:IsA("ImageLabel") then
            v.MouseEnter:connect(function()
                print("Showing "..Name.." Worth: "..Fruit.Details.Cost)
            end)
                
            v.MouseLeave:connect(function()
                print("Left "..Name)
            end)
        end
        
    end
end

You can simply use the .ChildAdded event, which fires when a child is added to the corresponding object.

I’m not sure, but how would I then get the Name and Fruit.Details
inside that Holder.ChildAdded?

Okay so I tried doing this, and it seems to be doing good.
but now the thing is, I get this error which I’m not sure why and how to fix it at all

[13:31:09.178 - Players.BosOfroblox.PlayerGui.UI.Inventory.Holder.ShowDetails:10: attempt to index upvalue ‘Fruit’ (a nil value)

[13:31:09.911 - Players.BosOfroblox.PlayerGui.UI.Inventory.Holder.ShowDetails:14: attempt to concatenate upvalue ‘Name’ (a nil value)

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local Fruits = require(ReplicatedStorage:WaitForChild("Fruits"))

local Holder = script.Parent

local function NewItemAdded(v, Name, Fruit)
        if v:IsA("ImageLabel") then
            v.MouseEnter:connect(function()
                print("Showing "..Name.." Worth: "..Fruit.Details.Cost)
            end)
                
            v.MouseLeave:connect(function()
                print("Left "..Name)
            end)
        end
end

for Name, Fruit in pairs(Fruits) do
    for _,v in pairs(Holder:GetChildren()) do    
		NewItemAdded(v, Name, Fruit)  
    end
end

Holder.ChildAdded:connect(NewItemAdded)

I tried printing v.Name and I got this when I hit the new Added Item: Nil

Thanks, I’ve played around with it and it seemed to be working

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local Fruits = require(ReplicatedStorage:WaitForChild("Fruits"))

local Holder = script.Parent

local function NewItemAdded(v)
	for Name, Fruit in pairs(Fruits) do 
		if v:IsA("ImageLabel") then
		    v.MouseEnter:connect(function()
				if v.Name == Name then
		    		print("Showing "..Name.." Worth: "..Fruit.Details.Cost)
				end
		    end)
		                
		    v.MouseLeave:connect(function()
		    	print("Left "..Name)
		    end)
	    end
	end
end

for _,v in pairs(Holder:GetChildren()) do  
	NewItemAdded(v)
end

Holder.ChildAdded:connect(NewItemAdded)
