How to disable collision to npc

Help and Feedback Scripting Support

i tried others with using setpartcollisiongroup but it seems its not working and i tried like using v:IsA("BasePart’) script Can i make that script like disabling player collision?

There might be another better solution, but here’s mine.
Serverscript in ServerScriptService:

game.Players.PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		for _, part in pairs(char:GetDescendants) do
			if part:IsA("BasePart") or part:IsA("MeshPart")
				part.CanCollide = false
			end
		end
	end)
end)

im not meaning that i mean how to disable collision includes players and npcs

You can use collision groups for this. Cant
make a script right now but this might help: Collision Filtering | Roblox Creator Documentation

local db = true
local part = script.Parent

function NotHuman(hit)
	local human = true
	if hit.Parent       :FindFirstChild("Humanoid") ~= nil then human = false end  
	if hit.Parent.Parent:FindFirstChild("Humanoid") ~= nil then human = false end  
	return human
end

part.Touched:Connect(function(hit)
	if db then db = false
		if NotHuman(hit) then
			print("not human")
--		else print("is human")
		end db = true
	end
end)

Edit: Added a debounce so it doesn’t over test.
It gets tricky as a part within a part on a human can touch.
Also you’re not asking for only players. So a double test is needed …
(this is untested)

This may still give false readings and considering you’re looking for not players
you may want to go with Collision Filtering.
