Lanes, Path or whatever it's called

Hi folks,

I am thinking about making some game for over a year now, picked Godot as engine as it works so well on Linux. And now I am here and need to ask stupid questions. Already sorry for that. I my head I have some idea but it needs traffic. Nothing fancy, especially not as Godot noob. I would be happy already if at one side of my floor some item would appear and go to the other side, following a path. Imagine like a road or rail. I started with 2D and played around with the PathFollow2D and a sprite walking along that, that worked fine. I know there is a PathFollow for 3D, but is it the way to go for Godot?

I've found lot of tutorials for shooters, RPG and car (self driving) race games. Nothing yet about having something like a transportion game or anything.

Thanks for reading and like to hear from you.

Maybe astar is a good place to start?

Thanks for the video. Maybe I am too new to Godot but I don't see the link here. The video seems over the top for me currently. Or do you have to make something like the red cubes just in a straight line to follow a road or track?

Hi,

Probably path follow could be good enough if you want your object to follow some already defined paths (when you know already exactly how you want movement to look like), but in most cases when you have some characters/vechicles etc. you don't know exactly when they will be at the moment of movement start and you don't know where they may go (for example player can select that), so defining paths for all possible cases is impossible.

That's why another and probably more often used idea is to use Navigation node. With Navigation node you define some meshes as "ground" you want to allow moving on and then you can obtain path from one position to another using Navigation node. To do that you need to add Navigation to your scene and add some NavigationMeshInstance nodes as children. That will define area you want allow your objects (characters/vechicles?) moving on. Then you can find path by myNavigationNode.get_simple_path(startPoint, endPoint) and you need to make object follow it to move from start to end point.

That sounds useful and interesting, I will dig deeper on topic Navigation. Thank you for pointing me the direction!
