No Clip [Car Help!]

[Ur_Dadeyyyyyy (Kanye_North)]

Hello guys!

I am trying to make it so that the player has to press “E” to enter the vehicle, rather than walking through.
… and yes, I tried enabling Can Collide, but the car just didn’t move…

Thanks!

Proximity prompts, Disable the car seat so players can’t get into it by walking into it

local proximityPrompt= --Just get a reference to your proximity prompt here
local seat= --The seat you're gonna have to enable later in the script

proximityPrompt.Trigerred:Connect(function(player)
local character=player.Character
if not character then return end --Just incase, likely not needed
seat.Disabled=false
seat:Sit(character.Humanoid)
end)

seat:GetPropertyChangedSignal("Occupant"):Connect(function()
if seat.Occupant then return end --Player got in by the prompt
seat.Disabled=true
end)

Yeah, but players can still walk through the car… How can I fix that?

You can use collisiongroups to make only a select of objects to be able to collide/not collide with the said object

local PhysicsService = game:GetService("PhysicsService")
 
-- Create two collision groups
PhysicsService:CreateCollisionGroup("Cars")
PhysicsService:CreateCollisionGroup("Players")

-- Make the groups collide with each other
PhysicsService:CollisionGroupSetCollidable("Cars", "Players", true)

then loop through player’s character and set all their limbs collisiongroup to players like this:

for i,v in pairs(player.Character:GetDescendants()) do
    if v:IsA("BasePart") then
          PhysicsService:SetPartCollisionGroup(v, "Players")
    end
end

do the same for the car but set their collision group to “Cars” instead

I am having issues…

This script is in the character

local player = script.Parent
local PhysicsService = game:GetService("PhysicsService")

for i,v in pairs(player:GetDescendants()) do
	if v:IsA("MeshPart") then
		PhysicsService:SetPartCollisionGroup(v, "Players")
		print("f")
	end
end

[uriel_Gamer444 (Uri)]

BasePart and MeshPart are not the same

[Ur_Dadeyyyyyy (Kanye_North)]

When I use BasePart, nothing happens, it doesn’t change anything

[uriel_Gamer444 (Uri)]

That’s bizzare, MeshParts fall under BaseParts

[Frostholl (Frost)]

make sure you set the “Cars” collision group to car parts or it wont work

[Ur_Dadeyyyyyy (Kanye_North)]

@uriel_Gamer444 @Frostholl

local player = script.Parent
local PhysicsService = game:GetService("PhysicsService")

for i,v in pairs(player:GetDescendants()) do
	if v:IsA("BasePart") then
		PhysicsService:SetPartCollisionGroup(v, "Players")
		print("f")
	end
end

What am I doing wrong?

[uriel_Gamer444 (Uri)]

It could be running before the character actually loads in,so when it gets decendants the character still has no instances in it

[Frostholl (Frost)]

It’s supposed to be a server script, also i’d suggest you use characteradded for that instead of whatever you’re doing right now…

[Ur_Dadeyyyyyy (Kanye_North)]

So everything seems to be working… but I can still collide with it… is it something to do with the car’s cancolide being false?

local PhysicsService = game:GetService("PhysicsService")
local part = script.Parent

	local function setCollisionGroup(object)
		if object:IsA("BasePart") then
		object.CollisionGroup = "Cars"
	end
	end

local function loopDescendants(parent)
	for _, child in ipairs(parent:GetDescendants()) do
		setCollisionGroup(child)
	end
end

loopDescendants(part)

…

local PhysicsService = game:GetService("PhysicsService")
local Players = game:GetService("Players")

PhysicsService:RegisterCollisionGroup("Players")
PhysicsService:RegisterCollisionGroup("Cars") --
PhysicsService:CollisionGroupSetCollidable("Cars", "Players", false)

local function onDescendantAdded(descendant)
	if descendant:IsA("BasePart") then
		descendant.CollisionGroup = "Players"
	end
end

local function onCharacterAdded(character)
	for _, descendant in character:GetDescendants() do
		onDescendantAdded(descendant)
	end
	character.DescendantAdded:Connect(onDescendantAdded)
end

Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(onCharacterAdded)
end)

@Frostholl @uriel_Gamer444

Ideas?

[uriel_Gamer444 (Uri)]

If your character collides with the car when CanCollide is set to false then something us messed up, But I’m really not sure what you may be doing wrong

[Vvshenok]

run this script on the server

local PhysicsService = game:GetService("PhysicsService")

local function setCollisionGroupForModel(model, collisionGroup)
    for _, descendant in pairs(model:GetDescendants()) do
        if descendant:IsA("BasePart") then
            PhysicsService:SetPartCollisionGroup(descendant, collisionGroup)
        end
    end
end

local function setCollisionGroupForAllPlayers(collisionGroup)
    for _, player in pairs(game.Players:GetPlayers()) do
        local character = player.Character
        if character then
            setCollisionGroupForModel(character, collisionGroup)
        end
    end
end

setCollisionGroupForAllPlayers("Players")

This will run for all players.

I modified your script a bit.

local PhysicsService = game:GetService("PhysicsService")
local part = script.Parent

local function setCollisionGroup(object)
	if object:IsA("BasePart") then
		object.CollisionGroup = "Cars"
	end
end

local function loopDescendants(parent)
	for _, child in ipairs(parent:GetDescendants()) do
		setCollisionGroup(child)
	end
end

loopDescendants(part)

part.DescendantAdded:Connect(function(descendant)
	setCollisionGroup(descendant)
end)
