The Y coordinate is used for "up", though for most objects that need
alignment (like lights, cameras, capsule collider, vehicle, etc.), the Z
axis is used as a "pointing towards" direction. This convention roughly
means that:
The Y coordinate is used for "up". As for the horizontal X/Z axes, Godot uses a
**right-handed** coordinate system. This means that for most objects that need
alignment (such as lights or cameras), the Z axis is used as a "pointing
towards" direction. This convention roughly means that:
- **X** is sides
- **Y** is up/down
- **Z** is front/back
