Awarding Points For Jumping and Landing - humanoid.StateChanged - OK in Local Script?

My second very rookie question here, and I’ll preface by acknowledging that the answer is probably: “Go learn client vs server / local vs normal script and come back.”

I am working on a scoring system that awards points after a player jumps and lands. I’m also adding a multiplier that awards additional points after landing if the player first touched a part. I have a leaderstat called Experience that is increased by 10 for each landing, unless the player has touched a “tricktoken” which makes the landing worth 20. Again, I only want to award points after landing, but only after a jump has occurred (if you were to run off a building and land, that does not count).

So I have the leaderstat called Experience, and player values for JumpCheck and Multiplier. I’m using the humanoid.StateChanged event to check for the ‘Jumping’ and ‘Landed’ states and doing the following: After a jump, I set the ‘JumpCheck’ value from 0 to 1. After a landing I award 10 points times the JumpCheck value, and the Multiplier value. After awarding the points the JumpCheck goes back to zero and the Trick Multiplier back to 1.

local character = script.Parent
local humanoid = character:WaitForChild("Humanoid")
local player = game.Players:GetPlayerFromCharacter(script.Parent)
local Multiplier = player.Multiplier.Value
local JumpCheck = player.JumpCheck.Value

humanoid.StateChanged:Connect(function(oldState, newState)
    if newState == Enum.HumanoidStateType.Jumping then
        print("Player Just Jumped - Setting JumpCheck to 1")
        JumpCheck = 1
        end
    end)

humanoid.StateChanged:Connect(function(oldState, newState)
    if newState == Enum.HumanoidStateType.Landed then
        print("Player just landed. If JumpCheck was 1, award 10 * the point multiplier, then reset multiplier back to 1 and jumpcheck to 0")
        player.leaderstats.Experience.Value = player.leaderstats.Experience.Value + (10 * JumpCheck * Multiplier)
        Multiplier = 1
        JumpCheck = 0
    end
end)

All of this works well to award the normal points; 10 at a time only, but I’m sure its not optimal, and the multiplier does not work, and I’m guessing these two issues are related.

Q1: This works to award 10 points with each jump in a local script in StarterCharacterScripts. If I use a regular script, the points are only awarded sporadically/infrequently. I believe this is due to the short time that the HumanoidStateType of Jumping and Landing last – perhaps not being picked up server-side. Is having these points awarded via local script in the character bad practice?

Q2: I’ve been unable to increase my point multiplier by touching the part in the game. I’ve tried a Touched event script inside the part in the Workspace, but have been unable to actually grant the multiplied points. My desired outcome is: You hit the part, set player.Multiplier.value to 2, then you jump and set player.JumpCheck.Value to 1, then you landed and awarded 10 * Mutiplier(2) * JumpCheck(1) = 20. I'm again guessing this doesn't work due to being handled on the server (part in the Workspace)?

This is inside the part:

db = false
script.Parent.Touched:Connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") then
        local player = game.Players:GetPlayerFromCharacter(hit.Parent)
        if db == false then
            db = true
            player.Multiplier.Value = 2
            wait(1)
            db = false
        end
    end
end)

If you made it this far, apologies for the length – I’m perfectly fine with the appropriate answer: “You’re out of your depth man – go research client, server, remote events, etc...and come back.”
