How would i make the players character change on textbutton click?

How would I make the players character change on textbutton click? I mean I have an idea but it doesnt work. I thought it would be somethin like

script.Parent.MouseButton1Click:Connect(function()
	local player = game.Players.LocalPlayer
	local char = game:WaitForChild('ServerStorage').CustomCharacter
	player.Character = char

how would I do it?

Don't try to access Server Storage via LocalScript as it will not work. Bcz Server Storage is accessable by server only.

This is not going to be a simple thing..

First, Local script in TextButton.

script.Parent.MouseButton1Click:Connect(function()
	game.ReplicatedStorage.YOUR_REMOTE_EVENT_NAME:FireServer()
end

Then, the Server script in ServerScriptService.

local function applyBodyColors(player, item, RigType)
	local char = player.Character
	item.Parent = char --Here, item is Body Color of the character
end

local function applyBodyPart(player, item, RigType)
	if RigType == "R15" then
		local replace = player.Character:FindFirstChild(item.Name)
	
		if replace then
			item.Parent = player.Character
			replace:Destroy()
		end

		player.Character.Humanoid:BuildRigFromAttachments()

	else -- If, the Rig type isn't R15

		for _, oldPart in ipairs(player.Character:GetChildren()) do
			if oldPart.ClassName == "CharacterMesh" then
				if oldPart.Name == item.BodyPart.Name then
					oldPart:Destroy()
				end
			end
		end
		item.Name = item.BodyPart.Name 
		item.Parent = player.Character
	end
end

local function AddItemToCharacter(player, item, rigType)
	local Type = item.ClassName

	if Type == "Accessory" or Type == "Shirt" or Type == "Pants" or Type == "Hats" then
		item.Parent = player.Character
	elseif Type == "Tool" then
		item.Parent = player.Backpack

	elseif item.Name == "Head" then
		player.Character.Head.Mesh:Destroy()
		item.Mesh.Parent = player.Character.Head
		player.Character.Head.face:Destroy()
		item.face.Parent = player.Character.Head
		player.Character.Head.Color = item.Color

	elseif Type == "MeshPart" then
		applyBodyPart(player, item, rigType)

	elseif Type == "BodyColors" then
		applyBodyColors(player, item, rigType)
	end
end

local function loadCharacter(player)
	local Character = player.Character or player.CharacterAdded:Wait()
	local RigType = Character.Humanoid.RigType == Enum.HumanoidRigType.R15 and "R15" or "R6"
	
	local ReplicatedStorage = game:GetService("ReplicatedStorage")
	local NewCharacter = ReplicatedStorage:WaitForChild("Character")

	if NewCharacter then
		if player:HasAppearanceLoaded() == false then
			repeat until player:HasAppearanceLoaded() == true
		end
	
		player:ClearCharacterAppearance()

		local EquipCharacter = NewCharacter:Clone()
		for _, item in pairs(EquipCharacter:GetChildren()) do
			AddItemToCharacter(player, item, RigType)
		end
	end
end

game.ReplicatedStorage.YOUR_REMOTE_EVENT_NAME.OnServerEvent:Connect(loadCharacter)

It's too long I know and just don't copy/paste. Try to understand the script first.

Make sure to add Remote Event in ReplicatedStorage and rename it to that you will be using in the script.

Also, add the character u want to give the player in ReplicatedStorage.

Lemme know if it helps! Please do give an Upvote if it helped you bcz the script took really long time to write.

You need to (locally) clone CustomCharacter to game.StarterPlayer And then name it “StarterCharacter” and do Player:LoadCharacter()

script 1: (localscript inside button)

script.Parent.MouseButton1Click:Connect(function()
	game.ReplicatedStorage.changecharacter:FireServer()
end)

script2(script inside serverscriptservice)

game.ReplicatedStorage.changecharacter.OnServerEvent:Connect(function(player)
		local ServerStorage = game:GetService("ServerStorage")
		ServerStorage.StarterCharacter:Clone().Parent = game.StarterPlayer
		player:LoadCharacter()
end)

Works! Thanks iOwn_You and BestCreativeBoy
