How to make character unselectable with F3X?

I am making an F3X Building game but when you join the game you can select yourself with the F3X btools. I don’t want the avatar to be selectable. How can I lock the character so you can’t? I can’t find anything about it online. All replies will be appreciated.

I think you can set the Locked property of the characters’ body parts to true and it should stop it? It depends on how F3X does selection, but if it allows selecting based on the Locked property, think what I mentioned should work

Where do I set it inside of studio, though?

You probably need a script for that, try this code out

local character = script.Parent

for _,part in pairs(character:GetDescendants()) do
	if not part:IsA("BasePart") then
		continue
	end
	part.Locked = true	
end

Put it in a script and put that script into StarterPlayer → StarterCharacterScripts

It didn’t work, sadly. I can still select characters with the F3X.

Did you put it in a local script, or server script? Make sure it is in a server script.

If that isn’t working, there isn’t a solution. F3X might just have it where they make every part non-locked, which you sadly cannot change. You can do a repeat loop, repeatedly setting characters locked, but I don’t know how that would work for you.

Side note: The locked property can be edited by scripts, meaning the object can be edited by scripts even when locked. Therefore, changing the locked property wouldn’t change much.

I did a server script and I do know there is a way since other bigger F3X games have the character locked. Thanks for trying to help, though! :slightly_smiling_face:

If you don’t want the character to be able to be referenced at all, turn archivable off. (I believe) this will fix the problem.
local character = script.Parent

for _,part in pairs(character:GetDescendants()) do
	if not part:IsA("BasePart") then
		continue
	end
	part.Archivable= true	
end

So I recently had to do this for my own game, what I ended up doing was adding an extra check under the Selection.Add() function of the module called Selection which checks if the Item being selected is not a model that has the same name as a player’s username, and if it is then it doesn’t add it to the Items table.

Replace the code in Building Tools > Core > Selection with this:
