How to pass player parameter from function to function in a server script?

hello all, I am trying to make my own stamina module for my games in the future, and im running into a few problems. number one I get an error right away because “passed value is not not” which I have marked as being an error below. I believe it is because of the parentheses next to the function call which fire it before the player is in, which I tried to fix with a few if statements, but I know that doesn’t stop the error from happening. The only problem is I don’t know how to pass the parameter of “player” without the parentheses. I have had this problem before, I would love to know a work around or if im doing something completely wrong. Also I know a lot of this script is probably very wrong but I haven’t even been able to test it because it breaks before I even get to that point.

local staminaScript = {}

local Players = game:GetService("Players")

local maxStamina = 100
local takeStamina = 25
local recoverStamina = 1
local maxRecovery = 5

local function recoveryLoop(player)
	if player then
		if player.recoveryTimer.Value > 0 then
		repeat 
				player.recoveryTimer.Value -= 1
				wait(1)
		until player.recoveryTimer.Value == 0
			player:WaitForChild("recovering").Value = false
		end
	end
end

local function takeStamina(player)
	if player then
		player.stamina.Value -= takeStamina
		print(player.stamina.Value) 
		player.recovering = true
		player.recoveryTimer = maxRecovery
		recoveryLoop(player)
	end
end

local function recoverStamina(player)
	if player then
		while wait(.1) do
			if player.recovering then return end
			player.Stamina.Value += recoverStamina
		end
	end
end

local function playerJumped(player, active)
	if player and active then 	
		player.recovering = true
		takeStamina(player)		
	end
end

local function func(player)
	local stamina = Instance.new("IntValue")
	stamina.Value = maxStamina
	stamina.Name = "Stamina"
	stamina.Parent = player
	local recoveryTimer = Instance.new("IntValue")
	recoveryTimer.Value = 5
	recoveryTimer.Name = "recoveryTimer"
	recoveryTimer.Parent = player
	local recovering = Instance.new("BoolValue")
	recovering.Value = true
	recovering.Name = "recovering"
	recovering.Parent = player
	
	recoverStamina(player)
	recoveryLoop(player)
	
	local char = player.Character or player.CharacterAdded:Wait()
-- passed value is not a function? VVVVVV
char:WaitForChild("Humanoid").Jumping:Connect(playerJumped(player))
--^^^^^^^^^^^^^^^^^^^^^
end

Players.PlayerAdded:Connect(func)

return staminaScript
#2

The only way I know to do it is changing that to:

char:WaitForChild("Humanoid").Jumping:Connect(function()
    func(player)
end)
#3

The error is saying that the result of playerJumped(player) is not a function. This is because the function is being called, not passed.

The only solution for this issue is what @domboss37 said
