How to clone and drag a model when a button is clicked?

Question

So I thought of having this for so long, I just don't know where to start. I am new to this language and I keep learning, but kind of hard for me. But I have built my very own custom character which took 2 weeks for me. Anyway, For my question. An example is if I have a button and I click it, a model will be clone and I can drag that model and put it anywhere nearby. What possible method I can use to achieve this?

Answer 1

A really good place to start is to search the free models in Studio Toolbox for a 'Dragger Tool' or 'Model Dragger Tool' and then use the script inside to get started creating your own. I have learned to create my own custom draggers by doing this and it is way easier than you may think at first. Once you find a good dragger tool to borrow code from, if you need to enhance it, you can find the dragger api in the Roblox Wiki to help you further customize it to your specific needs.

http://wiki.roblox.com/index.php?title=API:Class/Dragger

EDIT: So here's the first dragger script that showed when I searched. It will drag models and parts but you will have to edit it to meet your requirements using the dragger api. Create a Tool in player.BackPack then create a LocalScript inside the Tool then copy and paste the code below into the LocalScript, and that will get you started.

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

Answer 2

First things first, I suggest for any future questions, you head over to https://scriptinghelpers.org/

now, on to your question, for cloning the model, you should use mouse.Target.Parent:Clone() or the GetTopParent(mouse.Target) function in my function library (which you can get here; http://www.roblox.com/item.aspx?id=244244638)

then deposit the model into workspace and MakeJoints()

the next step is to move the model, this can be tricky, but the simplest method is model:MoveTo(mouse.Hit.p) on mouse.Moved (but that's a little buggy)

Another method for movement would be to use the Handles class, but I'm not really familiar with it, so you'd have to figure that one out on your own.

To make the first method less buggy, I'd suggest something along the lines of

model:MoveTo(mouse.Hit.p.X, mouse.Target.Position.Y + (model:GetExtentsSize().Y / 2), mouse.Hit.p.Z) 

but you'd have to set up the mouse to ignore the model, which I can't really help with.
