I am trying to make an obby where you must finish before the walking NPC touches you. I have attached a kill brick at the front of the NPC to kill the players on touch.
Some of the jumps in the obby don’t let the NPC walk over it and it just falls off the map. Is there an efficient way to do this? I’ve tried making a bridge that covers the whole obby with a LocalScript inside it to check if the thing touching it is an NPC and then to turn CanCollide on only for the NPC and not the players but it does not seem to work.
I even added a Print command att the very start to verify that the script it working but it’s not, even though the LocalScipt is inside of Workspace.
In simpler terms, I am trying to make a part that can only be walked on by the NPC not the players.
Below is the picture of the obby with the red bit being the bridge for the NPC, it will be transparent .
I’ve heard of using something like CollisionGroups but I’m not sure if that will be the best option in this case.
This is the code inside the LocalScript inside the bridge part.
--Variables--
local Brick = script.Parent
local Workspace = game.Workspace
--End--
--Code--
Brick.Touched:Connect(function(hit)
local player = hit.Parent:GetPlayerFromCharacter()
if player.Name == "Noob" then
Brick.CanCollide = false
end
end)
Is there an alternative way of doing this and why is the script not working?
Many thanks.
You could add a BoolValue and name it isNpc then check for if it exists inside the object probably not the best way though. Here’s an example:
Brick.Touched:Connect(function(hit)
local player = hit.Parent:GetPlayerFromCharacter(hit.Parent)
if player:FindFirstChild("isNpc") then
Brick.CanCollide = false
end
end)
Use this in a server sided script and not a local script.
LocalScripts can’t run in workspace, you need to put it somewhere else
This is definitely the best option, you can do something like this:
--script in ServerScriptService
local bricks = {game.Workspace.Brick} -- insert all of the bricks that can only be walked through by the NPC
local NPC = workspace.NPC -- change to NPC's location
local PhysicsService = game:GetService("PhysicsService")
PhysicsService:RegisterCollisionGroup("Characters")
PhysicsService:RegisterCollisionGroup("NPCParts")
PhysicsService:CollisionGroupSetCollidable("Characters", "NPCParts", false) -- set characters not collidible with NPCParts
local function SetCollisionGroup(char) -- sets character's collision group
for i,v in pairs(char:GetDescendants()) do
if v:IsA("BasePart") then
v.CollisionGroup = "Characters"
end
end
end
game.Players.PlayerAdded:Connect(function(plr)
if player.Character then SetCollisionGroup(player.Character) end
player.CharacterAdded:Connect(SetCollisionGroup)
end)
for i,v in pairs(NPC:GetDescendants()) do -- set npc's collision groups
if v:IsA("BasePart") then
v.CollisionGroup = "NPCParts"
end
end
for i,v in pairs(bricks) do -- set bricks collision groups
v.CollisionGroup = "NPCParts"
end
Now the NPC can walk over the bricks and the players can’t, however the NPC will not collide with players
Don’t set the bricks’ CanCollide to false by the way.
local wps = game.Workspace
local bricks = {
wps.Ladder,
} -- insert all of the bricks that can only be walked through by the NPC
local NPC = workspace.Noob -- change to NPC's location
local PhysicsService = game:GetService("PhysicsService")
PhysicsService:RegisterCollisionGroup("Characters")
PhysicsService:RegisterCollisionGroup("NPCParts")
PhysicsService:CollisionGroupSetCollidable("Characters", "NPCParts", false) -- set characters not collidible with NPCParts
local function SetCollisionGroup(char) -- sets character's collision group
for i,v in pairs(char:GetDescendants()) do
if v:IsA("BasePart") then
v.CollisionGroup = "Characters"
end
end
end
game.Players.PlayerAdded:Connect(function(plr)
if plr.Character then SetCollisionGroup(plr.Character) end
plr.CharacterAdded:Connect(SetCollisionGroup)
end)
for i,v in pairs(NPC:GetDescendants()) do -- set npc's collision groups
if v:IsA("BasePart") then
v.CollisionGroup = "Characters"
end
end
for i,v in pairs(bricks) do -- set bricks collision groups
v.CollisionGroup = "Characters"
end```
He just walks right into the part, and I have checked it is the only part in workspace called Ladder.
#1 Instead of falling right through the part for the player it juts makes me float, I think it the humanoidRootPart that’s not letting it fall through.
#2 The NPC just stops here in the running animation, and I’m not sure why.
Maybe the parts just get added after the charAdded runs? You can do this
local wps = game.Workspace
local bricks = {
wps.Ladder,
} -- insert all of the bricks that can only be walked through by the NPC
local NPC = workspace.Noob -- change to NPC's location
local PhysicsService = game:GetService("PhysicsService")
PhysicsService:RegisterCollisionGroup("Characters")
PhysicsService:RegisterCollisionGroup("NPCParts")
PhysicsService:CollisionGroupSetCollidable("Characters", "NPCParts", false) -- set characters not collidible with NPCParts
local function DescendantAdded(descendant) -- descendant added
if descendant:IsA("BasePart") then
descendant.CollisionGroup = "Characters"
end
end
local function SetCollisionGroup(char) -- sets character's collision group
for i,v in pairs(char:GetDescendants()) do
DescendantAdded(v)
end
end
game.Players.PlayerAdded:Connect(function(plr)
if plr.Character then SetCollisionGroup(plr.Character) end
local DescAdded
plr.CharacterAdded:Connect(function(char)
SetCollisionGroup(char)
DescAdded = char.DescendantAdded:Connect(DescendantAdded) -- connects descendant added
plr.CharacterAdded:Once(function() -- disconnects event when player respawns to prevent leaks
DescAdded:Disconnect()
return
end)
end)
end)
for i,v in pairs(NPC:GetDescendants()) do -- set npc's collision groups
if v:IsA("BasePart") then
v.CollisionGroup = "NPCParts"
end
end
for i,v in pairs(bricks) do -- set bricks collision groups
v.CollisionGroup = "Characters"
end
I don’t think this is relevant to the problem, can you tell me how it’s related?
Also is the NPC cloned somewhere else or it already exists in workspace?
The NPC already exists in workspace. It’s related because even though cancollide is on on the bridge part, the NPC just stops and does not seem to want to walk on it. I use the Humanoid:MoveTo command to go to an invisible part at the end but the NPC just stops, and this Script is also located in ServerScriptService. Anyway thanks for the edited script ill try it soon.
Here is the code for moving the NPC if it helps:
local points = game.Workspace.Point--points is a folder in workspace
function noobWalk ()
noob.HumanoidRootPart.Anchored = false
noob.Humanoid:MoveTo(points.Finish.Position)
noob.Humanoid.MoveToFinished:Wait()
end
wait (8)
noobWalk()
