PathFindingService

Een dienst die paden berekent.

Kernbegrippen	Details
PathfindingService	Een dienst die paden berekent.
Path	Een object dat een berekend pad vertegenwoordigt.
Waypoints	Punten langs het pad die het personage zal volgen.
Agent Parameters	Parameters die de bewegingsmogelijkheden en beperkingen van het personage definiëren (bijv. radius, hoogte, spronghoogte).
Blocked Event	Een gebeurtenis die wordt geactiveerd wanneer het pad wordt geblokkeerd.
StatusChanged Event	Een gebeurtenis die wordt geactiveerd wanneer de status van het pad verandert.

Definieer Startpunt en Eindpunt

Roblox Studio

local PathfindingService = game:GetService("PathfindingService")
local character = workspace:WaitForChild("NPC")
local humanoid = character:WaitForChild("Humanoid")
local humanoidRootPart = character:WaitForChild("HumanoidRootPart")
humanoidRootPart.Anchored = false

-- Get the NPC's start position
local startPoint
if character.PrimaryPart then
	startPoint = character.PrimaryPart.Position
elseif character:FindFirstChild("HumanoidRootPart") then
	startPoint = character.HumanoidRootPart.Position
else
	error("No valid part found to determine the NPC's position")
end

local endPoint = workspace.End.Position

Een Pad Creëren

-- Create a path object
local path = PathfindingService:CreatePath({
	AgentRadius = 2,
	AgentHeight = 5,
	AgentCanJump = true,
	AgentJumpHeight = 10,
	AgentMaxSlope = 45,
})

Een Pad Berekenen

-- Compute the path
path:ComputeAsync(startPoint, endPoint)

-- Check the path's status
if path.Status == Enum.PathStatus.Success then
	print("Path successfully computed.")
elseif path.Status == Enum.PathStatus.NoPath then
	print("No path could be found.")
elseif path.Status == Enum.PathStatus.Fail then
	print("Path computation failed.")
end

Het Pad Visualiseren

-- Visualize the path
local waypoints = path:GetWaypoints()

for _, waypoint in ipairs(waypoints) do
	local part = Instance.new("Part")
	part.Shape = Enum.PartType.Ball
	part.Material = Enum.Material.Neon
	part.Color = Color3.fromRGB(0, 255, 0)
	part.Size = Vector3.new(0.5, 0.5, 0.5)
	part.Position = waypoint.Position
	part.Anchored = true
	part.CanCollide = false
	part.Parent = workspace
end

Verplaats NPC Langs Het Pad

-- Move the character along the path
for _, waypoint in ipairs(waypoints) do
	print(waypoint.Position)
	print(humanoid)
	humanoid:MoveTo(waypoint.Position)
	humanoid.MoveToFinished:Wait()
end

print("Character has followed the path.")
