Roblox Scripting Tutorial: Path Finding Service

Introduction

• Presenter: Defconn Gear
• Topic: Path Finding Service in Roblox

What is Path Finding Service?

• Allows a character to navigate a calculated path.
• Example demonstrated: Character moves along a path to a specified point.

Setting Up

1. Create a Baseplate
   • Insert a character to move around.
2. Inserting a Character
   • Use Roblox Toolbox to find a free NPC or use the "Load Character" plugin.
   • Ensure the character has a humanoid to utilize movement functions.

Scripting the Path Finding

Steps to Script

1. Insert a Script
   • Name it "Pathfinding Script".
2. Get Path Finding Service local pathFindingService = game:GetService("PathfindingService")
3. Define Humanoid and Torso local human = script.Parent:WaitForChild("Humanoid") local torso = script.Parent:WaitForChild("Torso")
4. Creating the Path local path = pathFindingService:CreatePath()

Computing the Path

• Use ComputeAsync to define start and end points. path:ComputeAsync(torso.Position, game.Workspace.EndingPart.Position)

Moving the Character Along the Path

1. Get Waypoints local waypoints = path:GetWaypoints()
2. Loop Through Each Waypoint for i, waypoint in ipairs(waypoints) do human:MoveTo(waypoint.Position) human.MoveToFinished:Wait() end

Handling Obstacles

• If the path encounters a wall, it will get stuck unless it calculates the new path.
• Handle blocked paths using path.Status and PathBlocked.

Testing and Improvements

• Ensure the character can jump over obstacles by checking the waypoint action. if waypoint.Action == Enum.PathWaypointAction.Jump then human:ChangeState(Enum.HumanoidStateType.Jumping) end

Visualizing the Path

• Create visual indicators for waypoints as spheres or blocks using loops: local part = Instance.new("Part") part.Size = Vector3.new(1, 1, 1) part.Material = Enum.Material.Neon part.Position = waypoint.Position + Vector3.new(0, 2, 0) part.Parent = game.Workspace
