How To Make A Transparent Model Follow your Cursor?

Asked Jul 4, 2017308 views2 answers

So here is a script that does several things when you click a text button. BUT... I have a question! So you know how building games have a gui menu and stuff for placing objects and when you click an object, the GUI closes and a partially transparent model of the selected object follows your cursor. How can I do that? I am not looking for a script but just an explanation for how to do this.

partBlueprint = game.ReplicatedStorage.Part
local frame = script.Parent.Parent.Parent:WaitForChild('Items')
script.Parent.MouseButton1Click:connect(function()
frame.Visible = not frame.Visible
script.Parent.GUI.Disabled = false
script.Parent.Parent.Parent.PlacingPart.Visible = true
end)

Lets use the :SetPrimaryPartCFrame() function to move the models

First make sure your model has a PrimaryPart set

For the Button1Down event we will check to see if 1) the mouse.target isnt nil 2) the parent of the mouse.target is a model AND that its PRIMARY PART IS SET and 3) mouse.target.parent.parent == workspace . Then setting the target as the mouse.target's parent. adding that model to the targetfilter, and setting down to true

mouse.Button1Down:connect(function()
    if mouse.Target ~= nil then
        if mouse.Target.Parent:IsA("Model") and mouse.Target.Parent.PrimaryPart~=nil and mouse.target.parent.parent==workspace then
            target = mouse.Target.Parent
			mouse.TargetFilter=target
            down = true
        end
    end
end)

For the move event we will check if target isnt nil and down == true. then we will use :SetPrimaryPartCFrame() to move the model

mouse.Move:connect(function()
    if down == true then
        if target ~= nil then
            target:SetPrimaryPartCFrame(CFrame.new(mouse.Hit.p))
        end
    end
end)

Remember we can rotate the model by adding *CFrame.Angles() at the end of CFrame.new()

finally for the button1up event, we will set down to false, target to nill, and clear out the targetfilter

mouse.Button1Up:connect(function()
    down = false
    target = nil
    mouse.TargetFilter = nil
end)

Final form

local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()
local target = nil
local down = nil
local plr = game.Players.LocalPlayer

mouse.Button1Down:connect(function()
    if mouse.Target ~= nil then
        if mouse.Target.Parent:IsA("Model") and mouse.Target.Parent.PrimaryPart~=nil and mouse.target.parent.parent==workspace then
            target = mouse.Target.Parent
			mouse.TargetFilter=target
            down = true
        end
    end
end)

mouse.Move:connect(function()
    if down == true then
        if target ~= nil then
            target:SetPrimaryPartCFrame(CFrame.new(mouse.Hit.p))
        end
    end
end)

mouse.Button1Up:connect(function()
    down = false
    target = nil
    mouse.TargetFilter = nil
end)

Thank you for answering but I added this and this made the game very laggy.

@BunnyFlims1 I'm guessing your model has many parts?

AnonymousJul 4, 2017#

Before I even loaded in the part, it started lagging the game. And the part has only 1 part. It is a part.

@ BunnyFlims1 This script is for models with primary parts like you asked

I agree with @DanzLua but I think it's best to use RunService while moving objects instead of using mouse.Move

game:GetService("RunService").RenderStepped:connect(function()
    if down == true then
        if target ~= nil then
            target:SetPrimaryPartCFrame(CFrame.new(mouse.Hit.p))
        end
    end
end)

this isn't one of those things where you need to have it run so many times, the event is for efficiency and you wouldn't really see the difference
