Cameras
Camera2D renders an orthographic view from the node's 2D transform. Only cameras with Active on render.
Zoom and scaling
Zoom is pixels per world unit; the default is 64. Larger values show a smaller part of the world.
Scale decides how the view follows the window size:
| Mode | Behaviour |
|---|---|
| free | the visible area grows with the window |
| pixelPerfect | keeps whole-pixel scaling of the Virtual resolution |
| fitVirtual | fits the Virtual resolution into the window |
Several cameras
Viewport is the part of the screen the camera draws into, in normalized coordinates; (0, 0, 1, 1) is the whole screen. Cameras render by Order, lower first. Mask selects visibility layers, -1 renders all of them. A camera drawn over another one usually turns Clear off; otherwise it fills its viewport with ClearColor first.
