Godot Engine 3D grid pathfinding - progress update

Further work on my 3D grid pathfinding. Added enemies, camera rotation and the pillars are getting transparent when obstructing the camera view.
I'm using rays projected from the camera to the player and the enemies to check for obstacles. If the ray hits a pillar, I make it transparent and project another ray from the collision point (after adding exceptions) in case there's more than one pillar in a line.

I've uploaded the code: github.com/Yatchanek/Grid3D It's a total mess with lots of irrelevant garbage as it was just a test project that I abandoned. But maybe you'll be able to figure it out. The main scene should run just fine. It's made in Godot 3.5. I don't have a decent mic nor recording software, and I hate listening to my own voice recorded (even more so in a foreign language), so I'd probably not live through editing the video :)
