How do I have this work with more than one player?

So, I made like a NPC basketball defender once you touch the brick, which is z1. The script is in z1. Now, this script works, but I think and it seems it only works for the first person who enters the server, or who touches z1. How do I allow it to work with every player rather than just 1, and efficiently? The other variables are for later on, like NPC defense. I've been on this problem for a week and it is rather frustrating and I'm falling behind on my deadline of when I wish to finish this.

LW = game.Workspace.zone.LW
Mid = game.Workspace.zone.Mid
OPG = game.Workspace.zone.OPG
RW = game.Workspace.zone.RW
opg1 = false
lw1 = false
mid1 = false
rw1 = false
v = game.Players:GetPlayers()
f = game.Players:GetFullName()
LeftArm = game.Workspace.zone.OPG["Left Arm"]
LeftLeg = game.Workspace.zone.OPG["Left Leg"]
RightArm = game.Workspace.zone.OPG["Right Arm"]
RightLeg = game.Workspace.zone.OPG["Right Leg"]
Head = game.Workspace.zone.OPG.Head
HumanoidRootPart = game.Workspace.zone.OPG.HumanoidRootPart
Torso = game.Workspace.zone.OPG.Torso
z1 = game.Workspace.zone.Zones.z1
z2 = game.Workspace.zone.Zones.z2
z3 = game.Workspace.zone.Zones.z3
z4 = game.Workspace.zone.Zones.z4
z5 = game.Workspace.zone.Zones.z5


 

game.Players.PlayerAdded:connect(function()
    local plr = game.Players:GetPlayers()
    local f=    game.Players:GetChildren()
        for i = 1, #f do
            print(f[i])
    end
end)
z1.Touched:connect(function(hit)
        local hum = hit.Parent:FindFirstChild("Humanoid")
                if opg1 == false and hit.Parent:FindFirstChild("Basketball") then
                        opg1 = true
                        print("Found Player")
        local plr = game.Players:GetPlayers()
        local f=    game.Players:GetChildren()
for i = 1, #f do
	if f[i].Character then
		playerinGame = f[i].Character
	end
	while opg1 == true do
           wait(0.5)
            OPG.Humanoid:MoveTo(playerinGame.Basketball.Handle.Position - Vector3.new(2,0,0))
        end
end
        
        else
            print("Did not find player")
    end

end)
 

 

z5.Touched:connect(function(hit)
    local hum = hit.Parent:FindFirstChild("Humanoid")
    if opg1 == true and hum and lw1 == false and rw1 == false and mid1 == false then
        opg1 = false
		lw1 = false
		rw1 = false
		mid1 = false
        game.Workspace.zone.Zones.z1:Destroy()
        OPG.Humanoid.WalkToPoint = Vector3.new(-1.344, 13.419, -26.512)
        wait(3)

		s.Parent = game.Workspace.zone.Zones
        z1.Parent = game.Workspace.zone.Zones
