How to make npcs and players not collide

Help and Feedback Scripting Support
#1

I’ve been trying to make my NPCs to stop colliding with the player’s characters in-game.

I’ve tried using physics service, but that didn’t work. Here is the code for the physics service script, please help, and thanks!

local PS = game:GetService("PhysicsService")
PS:CreateCollisionGroup("Player")
PS:CollisionGroupSetCollidable("Player","Player",false)
PS:CreateCollisionGroup("NPC")
PS:CollisionGroupSetCollidable("NPC","NPC",false)

PS:CollisionGroupSetCollidable("NPC","Player",false)

game.Players.PlayerAdded:Connect(function(Player)
Player.CharacterAdded:Connect(function(Character)
	Character:WaitForChild("HumanoidRootPart")
	Character:WaitForChild("Head")
	Character:WaitForChild("Humanoid")
	for i,v in pairs(Character:GetChildren()) do
		if v:IsA("BasePart") then
			PS:SetPartCollisionGroup(v,"Player")
		end
	end
end)
end)
spawn(function()
for i = 1,math.huge do
for _, v in pairs(game.Workspace.NPCS:GetChildren()) do
if v and v:FindFirstChildOfClass("Humanoid") then
	for _,b in pairs(v:GetChildren()) do
		if b:IsA("Part") then
			PS:SetPartCollisionGroup(b,"NPC")
		end
		wait()
	end
end
wait()
end
wait(0.001)
end
end)

Try turning off cancollide in the npc locally on the client.

The can collide just loop sets itself back on

I think he meant literally looping through the descendants of the NPC on a local-sided script and setting the CanCollide value to false.

Still didn’t work, this is the script i used.

local npcs = game.Workspace.NPCS

for i,obj in pairs(npcs:GetDescendants()) do

if obj:IsA("BasePart") then

obj.CanCollide = false

end

end

edit: is local-sided*

Wait the instance NPCS is a folder with all the npc models right? Because that would mean there are no base parts there, just models.

Quickly copied your script then modified it. Might have some errors.

local npcs = game.Workspace.NPCS

for i,obj in pairs(npcs:GetDescendants()) do

if obj:IsA("Model") then

obj.HumanoidRootPart.Cancollide = false

end

end

Im using GetDescendants(), so it does reach the baseparts of the npcs. will try out your script tho, thanks.

Sorry, but it didn’t work. I also forgot to include that the npc is a R6 rig.

Try giving each NPC unique names. I doubt it will help but it would make the script less confusing to think about

you have to use a runservice.Stepped loop on the client in order to make it non collidable; otherwise, it will just set the property right back to true

Didn’t work for me, here’s the script:

local npcs = game.Workspace.NPCS

game:GetService("RunService").Stepped:Connect(function()

for i,obj in pairs(npcs:GetDescendants()) do

if obj:IsA("BasePart") then

obj.HumanoidRootPart.CanCollide = false

end

end

end)

local npcs = game.Workspace.NPCS


for i,obj in pairs(npcs:GetDescendants()) do

if obj:IsA("BasePart") then
game:GetService("RunService").Stepped:Connect(function()

obj.CanCollide = false

end)

end

end

if this doesn’t work, it’s not the scripts fault
