Hello, It’s me again.
I am trying to make a car that drives itself for my upcoming game that needs to follow the roads, interact with players and stop at traffic lights.
All the methods I have tried either
A - Go off course after a bit and get lost
B - Is fixed so all turnings have to be the same size and ends up driving off the map
C - Can’t navigate to it’s marker
D - Don’t move in the first place
(NOTE : All of this work here is only to follow the road)
I have tried to use .Touched to see if it is on a road and whether it needs to turn which lead to result B.
I also tried getting it to run through a series of nodes and either turn left or right a bit to to stay on track which eventually runs off course and gets too far away from the node for the script to mark the destination as reached (Result A) I tried another system more the machine learning side where if it hit a wall, it would leave a marker there and respawn but the issue was that cars don’t have built-in pathfinding and I wasn’t able to produce pathfinding so it couldn’t navigate to it’s point (Result C). Finally as a last resort I tried tweening it (which I really don’t want to do as it doesn’t look real) but that didn’t move at all (Result D) (I would not like help with tweening, I don’t think it is practical for this use)
My code:
Node tracking:
for i,v in pairs(nodes:GetChildren()) do
local mag
repeat
mag = (seat.Position - v.Position).Magnitude
seat.ThrottleFloat = 0.7
--print(mag)
if last then
cf = CFrame.new(last.Position, v.Position)
--print(cf)
print(v.Attachment.WorldPosition.X)
print(last.Attachment.WorldPosition.X)
if v.Attachment.WorldPosition.X > last.Attachment.WorldPosition.X then
seat.SteerFloat = math.abs(cf.Y)*-0.3
else
seat.SteerFloat = cf.Y*0.3
end
end
wait()
until mag > 2 and mag < 7 or mag > 20
--seat.Steer = 0
seat.ThrottleFloat = -0.3
repeat wait() until mag > 2 and mag < 7
seat.Throttle = 0
--print(mag)
last = v
end
Machine Learning:
script.Parent.Hitter.Touched:Connect(function(hit)
if hit.Parent ~= workspace.RoadNodes then
seat.Throttle = -0.2
wait(1)
seat.Throttle = 0
table.insert(points, {script.Parent.NodeCreator.Position.X, script.Parent.NodeCreator.Position.Z})
end
end)
Check to see if it’s on road:
frontWheel.Touched:Connect(function(hit)
if hit.Parent == workspace.Road then
seat.Throttle = 1
if hit.Name == "Left" then
seat.SteerFloat = -0.269067
elseif hit.Name == "Right" then
seat.SteerFloat = 0.269067
else
seat.SteerFloat = 0
end
last = hit
else
seat.Throttle = -2
end
end)
Tweening:
for i,v in pairs(nodes:GetChildren()) do
print(i)
if last then
cf = CFrame.new(last.Position, v.Position)
local distance =(v.Position - seat.Position).Magnitude
print(distance)
tweenService:Create(base, TweenInfo.new(distance,Enum.EasingStyle.Linear), {CFrame = v.CFrame}):Play()
local cr = coroutine.create(function()
print(base.Position)
end)
coroutine.resume(cr)
wait(distance/2)
end
last = v
end
I’ve just about had it with these cars. If anyone could help me with Self-Driving cars it would be very much appreciated. I’ll say it again down here, I’d rather not use the tweening method.
Thanks.
so would my car look like that or should the npc be an entire npc
