所以我想了这么久，我只是不知道从哪里开始。我是这门语言的新手，我一直在学习，但对我来说有点难。但是我已经建立了自己的自定义角色，这对我来说花了 2 周时间。无论如何，对于我的问题。一个例子是，如果我有一个按钮并单击它，一个模型将被克隆，我可以拖动该模型并将其放在附近的任何地方。我可以使用什么方法来实现这一目标？

首先，我建议对于未来的任何问题，您可以前往https://scriptinghelpers.org/
现在，关于你的问题，为了克隆模型，你应该在我的函数库中使用 mouse.Target.Parent:Clone() 或 GetTopParent(mouse.Target) 函数（你可以在这里找到；http://www. roblox.com/item.aspx?id=244244638）
然后将模型存入工作区和 MakeJoints()
下一步是移动模型，这可能很棘手，但最简单的方法是 model:MoveTo(mouse.Hit.p) on mouse.Moved （但这有点麻烦）
另一种移动方法是使用 Handles 类，但我对它不是很熟悉，所以你必须自己弄清楚。
为了使第一种方法不那么容易出错，我建议一些类似的东西
model:MoveTo(mouse.Hit.p.X, mouse.Target.Position.Y + (model:GetExtentsSize().Y / 2), mouse.Hit.p.Z)
但是您必须设置鼠标以忽略模型，我对此无能为力。

一个非常好的起点是在 Studio Toolbox 中的免费模型中搜索“拖动工具”或“模型拖动工具”，然后使用里面的脚本开始创建您自己的。通过这样做，我学会了创建自己的自定义拖动器，这比您最初想象的要容易得多。一旦你找到了一个好的拖拽工具来借用代码，如果你需要增强它，你可以在 Roblox Wiki 中找到拖拽 api 来帮助你进一步定制它以满足你的特定需求。
http://wiki.roblox.com/index.php?title=API:Class/Dragger
编辑：所以这是我搜索时显示的第一个拖动脚本。它将拖动模型和零件，但您必须使用拖动器 api 对其进行编辑以满足您的要求。在 player.BackPack 中创建一个工具，然后在该工具中创建一个 LocalScript，然后将下面的代码复制并粘贴到 LocalScript 中，这样您就可以开始了。
local Tool = script.Parent
enabled = true
local origTexture = Tool.TextureId
game:GetService("ContentProvider"):Preload("rbxasset://icons/freemove_sel.png")
local selectionBox
local currentSelection
local currentSelectionColors = {}
local selectionLasso
local inGui = false
local inPalette = false
local lockTime = 0
function canSelectObject(part)
return part and not (part.Locked) and (part.Position - script.Parent.Parent.Head.Position).Magnitude < 60
end
function findModel(part)
while part ~= nil do
if part.className == "Model" then
return part
end
part = part.Parent
end
return nil
end
function startDrag(mousePart, hitPoint, collection)
dragger = Instance.new("Dragger")
pcall(function() dragger:MouseDown(mousePart, hitPoint, collection) end)
end
function collectBaseParts(object, collection)
if object:IsA("BasePart") then
collection[#collection+1] = object
end
for index,child in pairs(object:GetChildren()) do
collectBaseParts(child, collection)
end
end
function onMouseDown(mouse)
mouse.Icon ="rbxasset://textures\\GrabRotateCursor.png"
local part = mouse.Target

local hitPoint = mouse.Hit:toObjectSpace(part.CFrame).p
if trySelection(part) then
local instances = {}
collectBaseParts(currentSelection, instances)
startDrag(part, hitPoint, instances)
return
