PathVisualizer – Lightweight Pathfinding Visualization Module
Hey everyone! I made a small module that lets you visualize pathfinding routes in your game. Figured I’d share it since I couldn’t really find anything clean for this.
Basically, you give it a target, could be a Part, Model, Attachment, or just a Vector3, and it draws a live-updating path from the player’s character to that target. The path recomputes as the player moves so it stays accurate, and the visuals scale down as you get closer so it doesn’t look weird when you’re right on top of the destination.
How to use it:
Drop the module into ReplicatedStorage and require it from any client script. The API is pretty straightforward:
local PathVisualizer = require(ReplicatedStorage.PathVisualizer)
local vis = PathVisualizer.new()
-- point it at anything
vis:SetTarget(workspace.SomePart)
vis:SetTarget(someModel)
vis:SetTarget(Vector3.new(50, 0, 100))
-- swap targets whenever
vis:SetTarget(workspace.SomeOtherThing)
-- done with it
vis:ClearTarget()
-- check state
vis:IsActive() -- true/false
vis:GetTarget() -- returns current target
-- full cleanup
vis:Destroy()
There’s no UI or input handling baked into the module itself so you can hook it up however you want, a button, a keybind, proximity triggers, quest systems, whatever works for your game.
One thing worth noting: pathfinding relies on the navmesh, so really thin or small parts (or stuff that’s sunk into the ground) might not register as obstacles. That’s just how PathfindingService works. If you run into that you can slap a PathfindingModifier on those parts with PassThrough set to false and it’ll fix it.
The whole thing runs client-side, all the visuals are parented under the camera so nothing replicates. Should work in pretty much any game without needing to touch anything else.
Let me know if you have any questions or suggestions, always open to feedback!
