I’m trying to make an auto drive system, I’m detecting when the vehicle has reached the destination by checking if the distance to the destination is less than 30, then I’d call a function to calculate the next destination for the vehicle to go to.
The problem is, when the vehicle is in that distance, it runs the calculation more than once, which causes it to set the destination to the 4th destination after that, instead of that one.
How can I stop it from doing this?
local function onStepped(_, deltaTime: number)
-- Calculate the direction to the target
local targetOffset = chassis.CFrame:PointToObjectSpace(target)
-- Calculate the distance to the target
local distance = targetOffset.Magnitude
if distance < 30 then driveCar() return end
local function driveCar()
local path = pathfinder:FindPath(start, goal)
if (path) then
table.insert(path, 1, start)
table.insert(path, goal)
for i = num,num do -- Chooses the next destination after the last, every thing driveCar() is called
if num <= #path then -- Checks if number has gone over the amount of destinations
local p1 = path[i - 1]
local p2 = path[i]
target = p2 -- Sets the target variable to p2, which the renderstepped uses to make the car drive to p2.
end
end
num = num + 1
else
warn("Failed to find Path.")
end
end
local debounce = false
local function onStepped(_, deltaTime: number)
-- Calculate the direction to the target
local targetOffset = chassis.CFrame:PointToObjectSpace(target)
-- Calculate the distance to the target
local distance = targetOffset.Magnitude
if distance < 30 and debounce == false then
debounce = true
driveCar()
return
end
Turns out it’s not running multiple times, but it still skips destinations?? I’ve checked with running the driveCar() function every second and it didn’t skip anything, what’s different here?
Fixed it. The start position would constantly update because it is inside the driveCar() function. That’s why the distance between the paths seemed to increase exponentially. It shouldn’t be like that. Simply place the start and goal variable outside the driveCar() function and it should work just fine.
local start = Vector3.new(chassis.Position.X, chassis.Position.Y, chassis.Position.Z)
local goal = game.ReplicatedStorage.WaypointParts.End.Position
local function driveCar()
--local nodes = workspace:WaitForChild("NodeList")
--local nodeArray = nodes:GetChildren()
--local randomNode = nodeArray[math.random(1, #nodeArray)]
--local goal = randomNode.Value
local path = pathfinder:FindPath(start, goal)
if (path) then
local pathfolder = Instance.new("Folder", workspace)
pathfolder.Name = "VisualPath"
print(num)
for i = num,num do -- Chooses the next destination after the last, every thing driveCar() is called
if num <= #path then
local p1 = path[i - 1]
local p2 = path[i]
local p = Instance.new("Part", pathfolder)
p.CanCollide = false
p.Anchored = true
p.TopSurface, p.BottomSurface = Enum.SurfaceType.Smooth, Enum.SurfaceType.Smooth
p.Color = Color3.fromRGB(255, 208, 90)
p.Size = Vector3.new(pathwidth,1, (p2 - p1).Magnitude)
p.CFrame = CFrame.new(p1:Lerp(p2, 0.5), p2)
p.Transparency = .1
target = p2
end
end
num = num + 1
--driveCar()
else
warn("Failed to find Path.")
end
end
No problem. Glad to help you out. Also, if the start and goal variables would be outside the driveCar() function, wouldn’t it be more optimized if the path variable is also outside since it doesn’t need to constantly update. In that way, the script won’t have to calculate a new path for a constant start and goal position, thus making it more optimized.
local start = Vector3.new(chassis.Position.X, chassis.Position.Y, chassis.Position.Z)
local goal = game.ReplicatedStorage.WaypointParts.End.Position
local path = pathfinder:FindPath(start, goal)
local function driveCar()
--local nodes = workspace:WaitForChild("NodeList")
--local nodeArray = nodes:GetChildren()
--local randomNode = nodeArray[math.random(1, #nodeArray)]
--local goal = randomNode.Value
if (path) then
local pathfolder = Instance.new("Folder", workspace)
pathfolder.Name = "VisualPath"
print(num)
for i = num,num do -- Chooses the next destination after the last, every thing driveCar() is called
if num <= #path then
local p1 = path[i - 1]
local p2 = path[i]
local p = Instance.new("Part", pathfolder)
p.CanCollide = false
p.Anchored = true
p.TopSurface, p.BottomSurface = Enum.SurfaceType.Smooth, Enum.SurfaceType.Smooth
p.Color = Color3.fromRGB(255, 208, 90)
p.Size = Vector3.new(pathwidth,1, (p2 - p1).Magnitude)
p.CFrame = CFrame.new(p1:Lerp(p2, 0.5), p2)
p.Transparency = .1
target = p2
end
end
num = num + 1
--driveCar()
else
warn("Failed to find Path.")
end
end
