BodyPosition not changing? - roblox

Question

I've been sitting at my laptop for about an hour trying to figure out what's going on. I did this exact same thing yesterday and it worked. Please help.
Explaining the program:
The program takes the object that the mouse is pointing at, if you click the object gravitates toward the mouse.
local player = game.Players.LocalPlayer
local runservice = game:GetService("RunService")
local character = player.Character
local humanoid = character.Humanoid
local camera = workspace.Camera
local mouse = player:GetMouse()
local mousepos = mouse.hit.p
local grabbed = false
local function grabbedobj(obj) --this is the thing i need help on
local bodypos = obj.BodyPosition.Position
local pos = obj.Position
obj.Anchored = false
mouse.Button1Down:Connect(function()
grabbed = true
end)
mouse.Button1Up:Connect(function()
grabbed = false
end)
if grabbed == true then
print(obj.BodyPosition.Position)
bodypos = Vector3.new(mousepos.X, mousepos.Y, mousepos.Z) --really important
end
if grabbed == false then
bodypos = Vector3.new(pos.X, -25, pos.Z)
pos = Vector3.new(bodypos.X, pos.Y, bodypos.Z)
end
end
local function setup()
mousepos = mouse.hit.p
if mouse.Target ~= nil and mouse.Target.Parent == game.Workspace.IntObj then
grabbedobj(mouse.Target) --takes object that the mouse is pointing at
end
end
while wait(.1) do
setup()
end

Lets shuffle the code a little bit so it does what I think you want to do. You might have mixed up some things while trying to debug this. So here:
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local grabbed = false
local obj
mouse.Button1Down:Connect(function()
if mouse.Target ~= nil and mouse.Target.Parent == game.Workspace.IntObj then
obj = mouse.Target
obj.Anchored = false
grabbed = true
end
end)
mouse.Button1Up:Connect(function()
if (grabbed) then
grabbed = false--BodyPosition
obj.BodyPosition.Position = Vector3.new(obj.Position.X, 0.1, obj.Position.Z)
obj.Anchored = true
end
end)
local function move()
if (grabbed) then
local mousepos = mouse.hit.p
obj.BodyPosition.Position = Vector3.new(mousepos.X, mousepos.Y, mousepos.Z)
print(obj.BodyPosition.Position)
end
end
while wait(.1) do
move()
end
When you click the mouse it checks if you click your part that is in IntObj. It will retain a reference to that part and then moves it with the mouse. When you release the button it will drop it at its location.
So this LocalScript should work but it has an issue updating the BodyPosition as you said in the title. The reason for that is that you can only update server parts from your client if you give the client permission from the server for it. You could write a remote function on the server and say:
game.ReplicatedStorage.RemoteFunction.OnServerInvoke = function(plr)
Workspace.IntObj.Part:SetNetworkOwner(plr)
end
If you call this from your local script's initialization, it will work. Note, that your part cannot be anchored for that.
Another way would be to just let the server do the updating. So instead of setting the
obj.BodyPosition.Position on the client you would call the remote function like this:
game.ReplicatedStorage.RemoteFunction:InvokeServer(Vector3.new(mousepos.X, mousepos.Y, mousepos.Z))
and then on the server you set the position:
game.ReplicatedStorage.RemoteFunction.OnServerInvoke = function(plr, bodyPos)
script.Parent.BodyPosition.Position = bodyPos
end
In that case, if you anchor/unanchor the part, do that on the server as well. Otherwise you'll get weird results.
