Trouble with serverside/clientside

[YT0674 (justa)]

So I got a LocalScript which removes the hp of a crystal:

local tool = script.Parent.Parent
local playersInZone = require(game.ReplicatedStorage:WaitForChild("Zones").Crystals.Crystal1second)
local re = game.ReplicatedStorage:WaitForChild("Zones").Crystals.SwingSound
local re2 = game.ReplicatedStorage:WaitForChild("Zones").Crystals.HitSound
local re3 = game.ReplicatedStorage:WaitForChild("Zones").Crystals.BreakSound
local PickaxeDamageBoost = game.Players.LocalPlayer.Stats.PickaxeDamageBoost
local playergui = game.Players.LocalPlayer.PlayerGui
local red =	playergui.CrystalButtons.ScreenGui.HPs.HP1.Red
local regenerate = playergui.CrystalButtons.ScreenGui.HPs.HP1.Regenerate
local isActivated = false
local PickaxeSpeed = game.Players.LocalPlayer.Stats.PickaxeSpeed
local PickaxeDmg = game.Players.LocalPlayer.Stats.PickaxeDmg.Value
local waittime = 0.54 - (0.54*PickaxeSpeed.Value*0.03)
local speedtime = 0.65 + (0.65*PickaxeSpeed.Value*0.03)

tool.Activated:Connect(function()
	for _, player in pairs(playersInZone) do
		local HP = game.Workspace.Crystals.HPs.HP1
		if HP.Value >= 1 then
			if not isActivated then
				isActivated = true
				local animationId = "rbxassetid://13862469344"
				local Humanoid = script.Parent.Parent.Parent.Humanoid
				local animation = Instance.new("Animation", Humanoid)
				animation.AnimationId = animationId
				local Animation = Humanoid.Animator:LoadAnimation(animation)
				Animation.Looped = false
				re:FireServer()
				Animation:Play()
				Animation:AdjustSpeed(speedtime)
				wait(waittime)
				Animation:Stop()
				if PickaxeDmg < HP.Value then
					re2:FireServer()
				end
				HP.Value -= PickaxeDmg --Removing the HP
				if HP.Value < 1 then
					red.Visible = false
					regenerate.Visible = true
					re3:FireServer()
				end
				isActivated = false
			end
		end
	end
end)

And I got a ServerScript that gives a pickaxe more damage (it’s a serverscript so datasave can save the value):

local RS = game:GetService("ReplicatedStorage")
local PickaxeDamageButton = RS.UpgradeButtons.Crystal:WaitForChild("PickaxeDamageButton")

PickaxeDamageButton.OnServerEvent:Connect(function(player)
	local Crystal = player.Stats.Crystal
	local PickaxeDamageBoost = player.Stats.PickaxeDamageBoost
	local PickaxeDmg = player.Stats.PickaxeDmg
	if PickaxeDamageBoost.Value >= 0 and PickaxeDamageBoost.Value < 2 then
		if Crystal.Value >= 10 then
			Crystal.Value -=10
			PickaxeDamageBoost.Value +=1
			PickaxeDmg.Value +=1 --Adding damage
		end
	elseif PickaxeDamageBoost.Value >= 2 and PickaxeDamageBoost.Value < 10 then
		if Crystal.Value >= 15 then
			Crystal.Value -=15
			PickaxeDamageBoost.Value +=1
			PickaxeDmg.Value +=1 --Adding damage
		end
	elseif PickaxeDamageBoost.Value >= 10 and PickaxeDamageBoost.Value < 12 then
		if Crystal.Value >= 100 then
			Crystal.Value -=100
			PickaxeDamageBoost.Value +=1
			PickaxeDmg.Value +=6 --Adding damage
		end
	elseif PickaxeDamageBoost.Value >= 12 and PickaxeDamageBoost.Value < 20 then
		if Crystal.Value >= 150 then
			Crystal.Value -=150
			PickaxeDamageBoost.Value +=1
			PickaxeDmg.Value +=6 --Adding damage
		end
	end
end)

The problem is when the PickaxeDmg value increases I still do the same amount of damage to a crystal. If I rejoin then it works. How can I fix this?

The problem you are facing is probably related to LocalScript and ServerScript not being properly synchronized when the pickaxe damage value is updated. When you rejoin the game, the values are reset and synchronized correctly, which is why it works after rejoining

Yes, thank you for your information. In the end all I had to do is destroy the pickaxe and put it back to the player’s backpack so it gets updated.
