the title is self explanatory, i’m working on a game that is about 2 teams capturing eachothers land and sword fighting to eliminate other players. here’s the source code help is appreciated!

local part = script.Parent
local siegetime = 5

local sieging = false

local ogcolor = part.BrickColor

local ss = game.ReplicatedStorage
local values = ss.Values
local redcaps = values.RedCaptures
local bluecaps = values.BlueCaptures


part.Touched:Connect(function(hit)
	local rs = game:GetService("ReplicatedStorage")
	local capture = rs.CaptureEvent
	
	local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
	local hum = plr.Character:WaitForChild("Humanoid")
	
	hum.Died:Connect(function()
		sieging = false
	end)

	local pgui = plr:WaitForChild("PlayerGui")
	local siegegui = pgui.SiegeGui
	
	if sieging == true or part.BrickColor == plr.Team.TeamColor then 
		 return
	else
		sieging = true
		
		hum.Died:Connect(function()
			sieging = false
			part.BrickColor = ogcolor
		end)
		
		plr.Character:WaitForChild("Humanoid").WalkSpeed = 0
		siegegui.Enabled = true
		
		for i = 1,5 do
			
			siegetime = siegetime-1
			siegegui.Main.Countdown.Text = "Sieging " .. siegetime .. " seconds left."
			
			if siegetime <= 0 then
				
				siegetime = 5
				siegegui.Main.Countdown.Text = "Siege Concluded!"
				
				if plr.Team.TeamColor == BrickColor.new("Really red") then
					
					redcaps.Value = redcaps.Value + 1
					bluecaps.Value = bluecaps.Value - 1
					
				elseif plr.Team.TeamColor == BrickColor.new("Dark blue") then
					
					bluecaps.Value = bluecaps.Value + 1
					redcaps.Value = redcaps.Value - 1
				end
			end
			task.wait(1)
		end

		part.BrickColor = plr.Team.TeamColor
		sieging = false
		plr.Character:WaitForChild("Humanoid").WalkSpeed = 16
		siegegui.Enabled = false
	end
	
end)

Check if plr is a Player (not nil)
