在 Roblox Studio 中制作多阶段选择器

Question

我正在制作一个阶段选择器，您可以在我的 Roblox 游戏中前进和后退阶段， 但它不起作用，这是代码：

local trasferHandler = {}

local TOTAL_STAGES_IN_GAME = 10

for _, stage in pairs(workspace.Checkpoints:GetChildren()) do
    if tonumber(stage.Name) > TOTAL_STAGES_IN_GAME then
        TOTAL_STAGES_IN_GAME = tonumber(stage.Name)
    end
end

function trasferHandler.up(plr, direction)
    local tpStage = plr.TeleportedStage
    if tpStage.Value < plr.leaderstats.Stage.Value then
        tpStage.Value += 1
        plr.Character.HumanoidRootPart.CFrame = workspace.Checkpoints[plr.TeleportedStage.Value].CFrame + Vector3.new(0,3.25,0)
    elseif tpStage.Value == plr.leaderstats.Stage.Value then
        tpStage.Value = 0
        plr.Character.HumanoidRootPart.CFrame = workspace.Checkpoints["0"].CFrame + Vector3.new(0,3.25,0)
    end
end

function trasferHandler.up2(plr, direction)
    local tpStage = plr.TeleportedStage
    if tpStage.Value < plr.leaderstats.Stage.Value then
        tpStage.Value += 10
        plr.Character.HumanoidRootPart.CFrame = workspace.Checkpoints[plr.TeleportedStage.Value].CFrame + Vector3.new(0,3.25,0)
    elseif tpStage.Value == plr.leaderstats.Stage.Value then
        tpStage.Value = 0
        plr.Character.HumanoidRootPart.CFrame = workspace.Checkpoints["0"].CFrame + Vector3.new(0,3.25,0)
    end
end



function trasferHandler.down2(plr, direction)
    local tpStage = plr.TeleportedStage
    if tpStage.Value > 10 then
        tpStage.Value -= 10
        plr.Character.HumanoidRootPart.CFrame = workspace.Checkpoints[tpStage.Value].CFrame + Vector3.new(0,3.25,0)
    elseif tpStage.Value == 0 then
        tpStage.Value = plr.leaderstats.Stage.Value
        plr.Character.HumanoidRootPart.CFrame = workspace.Checkpoints[plr.leaderstats.Stage.Value].CFrame + Vector3.new(0,3.25,0)
    end
end

return trasferHandler

我本以为它会改变我所处的阶段，但不知何故，它也打破了我倒退的能力。

local checkpoints=workspace.Checkpoints
local TOTAL_STAGES_IN_GAME=#checkpoints:children()
local function tp(player,x)
    local val=Instance.new"DoubleConstrainedValue"
    val.MaxValue=TOTAL_STAGES_IN_GAME-(checkpoints:FindFirstChild"0"and 1 or 0)
    val.MinValue=checkpoints:FindFirstChild"0"and 0 or 1
    local stage=player.leaderstats.Stage
    val.Value=stage.Value
    val.Value+=x
    stage.Value=val.Value
    local char=player.Character 
    char=char and char:move(checkpoints[stage.Value].Position)
    --player.TeleportedStage=stage.Value
end
return {
    up=function(player)
        tp(player,1)
    end,
    up2=function(player)
        tp(player,10)
    end,
    down2=function(player)
        tp(player,-10)
    end
}
