What causes character to load? Round Script

while true do

    print('bruuuh new loop')

    repeat wait() until #PlayersService:GetPlayers() >= 2 

    for i,v in pairs(PlayersService:GetPlayers()) do
        if not v.Character then
            v.CharacterAdded:Wait()
        end

        local HumanoidRootPart =v.Character.HumanoidRootPart
        print(HumanoidRootPart:GetChildren())
        --Move the HumanoidRootPart to Somewhere else


    end


    wait(120)

end

This is my round script

I basically want to move the humanoid when the character loads

But I am afraid that a exploiter can delay their character loading time somehow

or someone with bad wifi can delay their loading time

what does loading time depend on?
