Welding a part to a character. Primary parts to a player model?

Help and Feedback Scripting Support
#1

For the past 2 days i’ve been making a dash system. I’m almost done, and just need to get over this one hitch. A part is supposed to be welded to the player to act as a hitbox of sorts. Whenever I run the script, it says I need a primary part. The character model isn’t capable of having primary parts, though.

game.Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(char)
		local RP = char.HumanoidRootPart
		local T = char.LowerTorso
		local LT = Instance.new("Part", workspace)
		char.PrimaryPart = T
		LT.Size = Vector3.new(1.4, 1.8, 0.85)
		LT.Name = "PlayerHitBox"
		LT.Position = Vector3.new(187, 8.5, 122)	
		local partA = RP
		while true do
			RP.Parent = char
			wait(0.01)
		end
--local partB = char.HumanoidRootPart
local partB = LT


--partA.Position = Vector3.new(0, 10, 0)
--partB.Position = Vector3.new(0, 10, 10)
partA.Parent = workspace
partB.Parent = workspace

wait(0.01)
local weld = Instance.new("WeldConstraint")
weld.Parent = workspace
weld.Part0 = partA
weld.Part1 = partB
	end)
end)

any help is appreciated

Lua reads code from top to bottom, so it gets stuck in the while loop. Instead, you would want to do this:

spawn(function()
  while true do
		RP.Parent = char
		wait(0.01)
	end
end)

Spawn basically runs code inside of it on the side, while it runs the rest after.

Thanks for trying to help! The problem wasn’t in the loop, but rather because I was setting the lower torso as my primary part. It’s working fine now that I swapped it to lower torso being the weld in the HRP being the primary part. (Although the lower torso lost its shape. Is there a way to fix that?)

I don’t think so, but you shouldn’t have to worry about it.

I did it! Here’s the entire script.

   game.Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(char)
	
local RP = char.HumanoidRootPart
local T = char.LowerTorso
		local LT = Instance.new("Part", workspace)
		char.PrimaryPart = RP
		T.Size = Vector3.new(1, 0.4, 1) 
		LT.Size = Vector3.new(2.5, 5, 0.5) -- dont alter. It's perfect tbh
		LT.Transparency = 0.4 -- set this to 0. it's 0.4 for visual representation of hitbox
		LT.BrickColor = BrickColor.new("Bright green")
		LT.CanCollide = false -- biggie. Cant have it dicate our non dash movement
		LT.Name = "PlayerHitBox"
		LT.Position = Vector3.new(171.75, 5.996, 105.25)	-- should be 1.5 studs away on z axis. This position should change with the actual spawn
		LT.Massless = true -- also a biggie. If its off we go flying
		local partA = T
		spawn(function()
  while true do
				RP.Parent = char
				--pos is 171.75, 3.996, 105.25
		wait(0.01)
	end
end)
--local partB = char.HumanoidRootPart
local partB = LT


--partA.Position = Vector3.new(0, 10, 0)
--partB.Position = Vector3.new(0, 10, 10)
partA.Parent = workspace
partB.Parent = workspace
T.Transparency = 1
wait(0.01)
local weld = Instance.new("WeldConstraint")
weld.Parent = workspace
weld.Part0 = partA
weld.Part1 = partB


end)
end)
