Well, it causes moving forward to be on the negative Z-axis instead of the positive, which isn’t intuitive.
Also, when we’re looking at the front of our model in the editor, the positive Z-axis faces away from us and the positive X-axis is on the left. Kinda backwards.
Maybe there’s something I’m missing, but that’s the point of this thread.
Not if you think of forward as “towards you.” It comes from Math. X is right, Y is up, and then when doing 3D, Z is out of the page, bc that’s easiest to draw.
Well, in 2D, one would expect x and y to map to camera up/down and camera left/right in some way, depending on where we decide the origin goes on the screen. In the game world, gravity might be +/- y; it’s kind of irrelevant. In any case, z has to map to the axis the camera is looking down.
But IIRC you can just apply a global transformation and use any coordinate system you like.

I haven’t used Godot, but from the info you gave, it seems like they started as a 2D game engine.
For something started as 3D, I would expect x and y to be on the floor and +z to be against gravity.
