How do I make a script that puts a tool in your inventory based on a leaderstat?

Hello,

I have a leaderstat for kills, and I was wondering how I can have it give you a sword if you have a certain amount of kills. How could I do this?

Thank you, KreativleV2

This is not that hard to make and achieve

First to make this easier you should make a reward dictionaries for example:

local rewards = {
	[100] = "Your sword name here",
	[500] = "Your sword name here"
	
	-- you can add as many as you want
}

After that you want to reward the player with :GetPropertyChangedSignal. If you use DataStore this script will also work because upon loading data your value will get change if I am not wrong

local SS = game:GetService("ServerStorage")
local rewards = {
	[100] = "Part",
	[500] = "Your sword name here"
	
	-- you can add as many as you want
}

local function giveTool(player)
    for requirement, reward in pairs(rewards) do
	    if tonumber(requirement) <= kills.Value then
	        local hasSword
	        hasSword = player.Backpack:FindFirstChild(reward)

	        if hasSword then
		        return
	        else
		        local newSword = SS:WaitForChild(reward):Clone()
		        newSword.Parent = player.Backpack
	        end
	    end
    end
end

game.Players.PlayerAdded:Connect(function(player)
	-- your simple leaderstats script here
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player
	
	local kills = Instance.new("IntValue")
	kills.Name = "kills"
	kills.Parent = leaderstats
	
	kills:GetPropertyChangedSignal("Value"):Connect(function()
        giveTool(player)
	end)
    
    player.Character.CharacterAdded:Connect(function()
        giveTool(player)
    end)
end)

Note: You might need to check if player is holding a sword to prevent multiple rewards Edit: As elyz said below, I edited it so it gives you the sword after dying. Just look at my answer as a sequel for multiple rewards.

like AntoninFearless said, you can use the .Changed event to detect when a player reaches a certain amount of kills and give them the sword

keep in mind that the player's backpack is cleared when they die, so you'll need to give them the sword when they respawn too

local swordKillRequirement = someNumberHere -- you should probably use a table for this if you're going to add lots of different swords, but for just one sword a variable is enough
local sword = path.to.Tool

Players.PlayerAdded:Connect(function(player)

	-- blablabla leaderstats stuff goes here
	
	leaderstats.Kills.Changed:Connect(function(kills) -- for Values, the .Changed event only fires when the value changes, unlike other types of instances where it fires for every property change
		local tool = player.Backpack:FindFirstChild(sword.Name) or player.Character:FindFirstChild(sword.Name) -- tools get parented to the character when they're equipped, so we need to check in the character too
		if kills >= swordKillRequirement and not tool then
			sword:Clone().Parent = player.Backpack
		end
	end)

	-- add the sword when the player respawns
	player.CharacterAdded:Connect(function()
		if leaderstats.Kills.Value >= swordKillRequirement then
			sword:Clone().Parent = player.Backpack
		end
	end)

	-- datastore stuff goes here, if you have it

end)
