Swapping 2 players health

Help and Feedback Scripting Support
#1

Im trying to make a tool that when player 1 hits player 2 with the tool, their health gets swapped, so if player 1 had 30, and player 2 had 90, it would swap to player 1 having 90 and player 2 having 30, Ive searched online for tips on this but havent found anything explaining it.

Using a touch function, and some stored data you can achieve this. I would start on making the touch function and then I can guide you from there, Reply to this response if you want me to guide you through it

#3

Let me rephrase that, Using a touch function to connect a remote event, that fires to the server. Then after that in the server-sided script, you can get the player who got touched Health, and the player that was touching Health. Once you have those two data points, you can just swap them out with another.

This just applies if you’re using a local script

You can achieve that using BasePart | Roblox Creator Documentation

local player = script:FindFirstAncestorWhichIsA("Player") or game:GetService("Players"):GetPlayerFromCharacter(script.Parent.Parent)
local Part = script.Parent.Part
local Debounce = false

Part.Touched:Connect(function(hit)
	if not Debounce then
		Debounce = true
		local HumanoidTouched = hit.Parent:FindFirstChild("Humanoid")
		local HumanoidPlayer = player.Character:FindFirstChild("Humanoid")
		if HumanoidTouched and HumanoidPlayer then
			local playerTouched = game.Players:GetPlayerFromCharacter(hit.Parent)
			if playerTouched ~= player then
				if HumanoidTouched.Health > 0 and HumanoidPlayer.Health > 0 then
					local playerHealth = HumanoidPlayer.Health
					local touchedHealth = HumanoidTouched.Health
					HumanoidPlayer.Health = touchedHealth
					HumanoidTouched.Health = playerHealth
					task.wait(1)
					Debounce = false
				end
			end
		end
	end
end)

Very simple tool swapping the health of the player that gets clicked:
Script:

local Tool = script.Parent 
local Signal = Tool:WaitForChild("Signal")

function HealthSwap(player1, player2)
	local character1 = player1.Character 
	local character2 = player2.Character
	if not character1 or not character2 then return end 
	local humanoid1 = character1:FindFirstChildWhichIsA("Humanoid")
	local humanoid2 = character2:FindFirstChildWhichIsA("Humanoid")
	if not humanoid1 or not humanoid2 then return end 
	--swapping health
	local old = humanoid1.Health --storing old value
	humanoid1.Health = humanoid2.Health
	humanoid2.Health = old 
end

--if the player has equipped the tool, the request is valid
function Validate(player)
	if Tool.Parent == player.Character then 
		return true 
	else 
		return false 
	end
end

Signal.OnServerEvent:Connect(function(player, target)
	if Validate(player) then 
		HealthSwap(player, target)
	end
end)

LocalScript:

local Players = game:GetService("Players")

local Player = Players.LocalPlayer 
local Mouse = Player:GetMouse()

local Tool = script.Parent 
local Signal = Tool:WaitForChild("Signal")

Tool.Activated:Connect(function()
	local target = Mouse.Target 
	if not target then return end 
	local player2 = Players:GetPlayerFromCharacter(target.Parent)
	if player2 then 
		Signal:FireServer(player2)
	end
end)

The tool should look like this:
