Hey everyone! So I’ve been working on a game for quite some time now and I wanted to have a cool pop up screen whenever a proximityprompt attached to an object is triggered where the item pops up in a viewport display.
Kind of like Resident Evil 7 and 8 where when you pick up an object you can view it and rotate it whereever you want. But instead I wanted to make it so that there is an arrow button on each side and when you hold it the object rotates towards that direction like the avatar creator in Grand Piece. Everything else works but the issue i’m facing is that when I click on the buttons it doesn’t work.
This is what it looks like:
As you can see the rotation doesn’t work when it’s inside a viewportframe but it works when it’s in workspace:
This is the local script inside each button(the axis is different for each one this is just one of the 6 scripts)
local isHoldingMouse = false
local button = script.Parent
local part = workspace.Part
button.MouseButton1Down:Connect(function()
isHoldingMouse = true
while isHoldingMouse do
task.wait(0.01)
part.CFrame *= CFrame.Angles(0,0,math.rad(3))
end
end)
button.MouseButton1Up:Connect(function()
isHoldingMouse = false
end)
Hey! Viewport frames are pretty neat and personally I haven’t used them much.
However, I think I do recall that every instance must be a child of the ViewportFrame to be rendered, right? Your call here is on local part = workspace.Part and is not actually fetching the model within the frame.
I am going to go test what I said to make sure I am not just talking nonsense ( ͡° ͜ʖ ͡°), but I figure this is the issue
Oh shoot that’s the wrong script, the one i posted above was in the workspace one but this is the one in the game
local isHoldingMouse = false
local button = script.Parent
local part = game.Players.LocalPlayer.PlayerGui:WaitForChild("ScreenGui3").ViewportFrame.Part
button.MouseButton1Down:Connect(function()
isHoldingMouse = true
while isHoldingMouse do
task.wait(0.01)
part.CFrame *= CFrame.Angles(0,math.rad(3),0)
end
end)
button.MouseButton1Up:Connect(function()
isHoldingMouse = false
end)
Hmm, I tested this new script you just sent and it worked perfectly fine for me. I just used the default ViewportFrame GUI tutorial script provided by Roblox to make the viewport during runtime.
In my opinion, it seems that it would be better in this scenario to manage each button in a single script. That way you can change stuff easily and see if it is connecting properly.
Here is my world if you would like to compare and see what has gone wrong (must run the game): ViewportButtonTest.rbxl (35.3 KB)
If you want a 2D rotation, you can change the rotation property in the viewport frame:
while isHoldingMouse do
task.wait(0.01)
ViewPortFrame.Rotation += 1
end
However if you want a 3D you might need to either weld the entire gun first, there are great youtube tutorials on how to use WeldConstraints to do this, and then just change the CFrame of the primary part of the gun like this (Your method is a bit wrong and might result in that the gun gets positioned wrong). I would also suggest trying to rotate Z first and if it doesn’t work try rotate X:
Ok so, I made a model with 2 children. One is called Part which acts as a rootpart and is the primarypart of the model, and the other one is the gun who is welded to the other part. I did the first one, and it still didn’t work and I also tried the second method you sent and it also didn’t work
Are you able to just get a part moving in there? Just a part?
→ If you cannot, then your connections (like why the output is screaming at us) is the problem
Is the script that is being referenced in the output one of the button scripts?
Have you updated your script connections to be
local part = game.Players.LocalPlayer.PlayerGui:WaitForChild("ScreenGui3").ViewportFrame.Model.Part
or do it like this so its easier to reference
local VP = game.Players.LocalPlayer.PlayerGui:WaitForChild("ScreenGui3").ViewportFrame
local Model = VP.Model
local part = Model.Part
ok so i changed the script to this, it didn’t have any output errors but it also didn’t move and I also changed the script to a local script to see if it’d work as a local script
local isHoldingMouse = false
local button = script.Parent
local part = game.Players.LocalPlayer.PlayerGui:WaitForChild("ScreenGui3").ViewportFrame.Model.Part
button.MouseButton1Down:Connect(function()
isHoldingMouse = true
while isHoldingMouse do
task.wait(0.01)
part.CFrame *= CFrame.Angles(0,0,math.rad(-3))
end
end)
button.MouseButton1Up:Connect(function()
isHoldingMouse = false
end)
You will need to rotate the mesh gun part itself. Put the gun back under the viewport, remove the model and part and then alter your script to move just the Gun part. It might be wonky rotation but we’ll just need to see if it rotates for now
Ok so i messed with some things and it worked now!
local isHoldingMouse = false
local button = script.Parent
local Gun = game.Players.LocalPlayer.PlayerGui.ScreenGui3.ViewportFrame.Gun
button.MouseButton1Down:Connect(function()
isHoldingMouse = true
while isHoldingMouse do
task.wait(0.01)
Gun.CFrame *= CFrame.Angles(0,math.rad(3),0)
end
end)
button.MouseButton1Up:Connect(function()
isHoldingMouse = false
end)
idk what I did but this is the new script that works
By setting the CFrame of a primary part in a model the entire model should follow the CFrame.
Another problem is the while loop you have, you kind of initiate a new while loop every time the muse button is down. Instead try to move the while loop outside of the mouse button down event and put it in the very bottom of the script so it doesn’t interfere with anything, alternatively create a new task with task.spawn so that the while loop won’t block other processes in the script.
The error message is basically saying that the player object is nil. The playerGui is a member of the player so if it says that you are trying to index nil with playerGui that would mean that the player object is nil
