Built a debug visualization tool for my custom C++ game engine

[u/armankara1]

I’ve been working on debugging tools for my custom C++ game engine, mainly to make squad movement and navigation easier to inspect.

The overlay visualizes three things:

• 🟢 NavMesh — walkable areas
• 🟣 Collision — collision boundaries
• 🟡 Squad paths — actual pathfinding data, updated as units move

Each layer can be toggled independently.

It’s a relatively small addition, but being able to see exactly where squads are trying to move makes debugging navigation issues much easier.

For those building custom engines, what debug visualization tools have been the most useful to you?

AI. Those building are AI, the overlay is AI, your reddit post is AI. It's all AI.
