how do i make it so that a player cant collide with an unanchored part? I know I have to use collision groups, but I don’t know how to use them.

They’re pretty simple, you just have to make a no collision constraint in every part of the character and have Part0 as the part and Part1 as the player; Part0 and Part1 can be switched around and you can modify the script to make it just one player instead of all of them by replacing the variable g with the character and attaching :GetChildren() to it. I made a script like this a while ago so here it is.

-- Put this in the ServerScriptService or wherever it works for you.

while true do

walls = {game.Workspace.Wall, game.Workspace.Wall2} -- These parts are examples, put the walls you want in the table.

c = game.Players:GetChildren()

for i = 1, #c do
	if c[i].Character ~= nil and c[i].ClassName == "Player" then
		
		g = c[i].Character:GetChildren()
		
		for h = 1, #g do
			if g[h]:IsA("BasePart") then
				for x,l in ipairs(walls) do
				if g[h]:FindFirstChildOfClass("NoCollisionConstraint") and g[h]:FindFirstChildOfClass("NoCollisionConstraint").Part1 == l then return end -- if they already have a "NoCollisionConstraint" for this wall.
				local NoCollision = Instance.new("NoCollisionConstraint")
				NoCollision.Part0 = g[h]
				NoCollision.Part1 = l
				NoCollision.Parent = g[h]
					end
				end
			end
		end
	end
	wait(0.1)
end
