Service de Recherche de Chemin

Un service qui calcule des chemins.
Concepts ClésDétails
PathfindingServiceUn service qui calcule des chemins.
PathUn objet représentant un chemin calculé.
WaypointsPoints le long du chemin que le personnage suivra.
Agent ParametersParamètres définissant les capacités de mouvement et les limitations du personnage (par exemple, rayon, hauteur, hauteur de saut).
Blocked EventUn événement qui se déclenche lorsque le chemin est bloqué.
StatusChanged EventUn événement qui se déclenche lorsque l'état du chemin change.

Créer un Chemin

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

Calculer un Chemin

-- 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

Visualiser le Chemin

-- 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

Déplacer un PNJ le Long du Chemin

-- 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.")
