how do i give certain teams different walk speeds and other features? [closed]

Whatever script you use for them to change teams, add the lines to change their walkspeed. It’s kinda hard to tell you exactly what you do if you haven’t posted any scripts you use. Do you use a script for them to change teams?

Here's a script I wrote that should do what you want. I'll break down each step of it and what it does.

--Configuration for the teams, change the stuff in quotation marks to your team names
local Teams = {
    ["Red Team"] = {
        WalkSpeed = 20
    },
    ["Blue Team"] = {
        WalkSpeed = 24
    }
}

--A player joined the game
game:GetService("Players").PlayerAdded:Connect(function(player)
    player.CharacterAdded:Connect(function(character)
        --The player's character loaded, let's check what team they're on
        local Humanoid = character:WaitForChild("Humanoid") --Wait for the character's humanoid to load
        if not Teams[player.Team.Name] then
            --The player was on an unknown team, let's write a warning in the console
            warn(player.Name .. " was on a team that was not set up! (" .. player.Team.Name ..")")
        end
        Humanoid.WalkSpeed = Teams[player.Team.Name].WalkSpeed --Update the player's WalkSpeed
    end)
end)
