Camera2D

Camera node for 2D scenes.

Camera node for 2D scenes. It forces the screen (current layer) to scroll following this node. This makes it easier (and faster) to program scrollable scenes than manually changing the position of -based nodes.

This node is intended to be a simple helper to get things going quickly and it may happen that more functionality is desired to change how the camera works. To make your own custom camera node, inherit from Node2D and change the transform of the canvas by setting in Viewport (you can obtain the current by using Node.get_viewport).

Note that the node’s position doesn’t represent the actual position of the screen, which may differ due to applied smoothing or limits. You can use to get the real position.

enum AnchorMode:

ANCHOR_MODE_FIXED_TOP_LEFT = 0 —- The camera’s position is fixed so that the top-left corner is always at the origin.
ANCHOR_MODE_DRAG_CENTER = 1 —- The camera’s position takes into account vertical/horizontal offsets and the screen size.

enum Camera2DProcessMode:

CAMERA2D_PROCESS_PHYSICS = 0 —- The camera updates with the _physics_process callback.
CAMERA2D_PROCESS_IDLE = 1 —- The camera updates with the _process callback.

Property Descriptions

AnchorMode anchor_mode

Default	`1`
Setter	set_anchor_mode(value)
Getter	get_anchor_mode()

The Camera2D’s anchor point. See constants.

bool current

Default	`false`
Getter	is_current()

If true, the camera is the active camera for the current scene. Only one camera can be current, so setting a different camera current will disable this one.

Setter	set_custom_viewport(value)
Getter	get_custom_viewport()

The custom node attached to the Camera2D. If null or not a Viewport, uses the default viewport instead.

drag_margin_bottom

Default	`0.2`
Setter	set_drag_margin(value)
Getter	get_drag_margin()

Bottom margin needed to drag the camera. A value of 1 makes the camera move only when reaching the edge of the screen.

bool drag_margin_h_enabled

Default	`false`
Setter	set_h_drag_enabled(value)
Getter	is_h_drag_enabled()

If true, the camera only moves when reaching the horizontal drag margins. If false, the camera moves horizontally regardless of margins.

drag_margin_left

Default	`0.2`
Setter	set_drag_margin(value)
Getter	get_drag_margin()

Left margin needed to drag the camera. A value of 1 makes the camera move only when reaching the edge of the screen.

float drag_margin_right

Default	`0.2`
Setter	set_drag_margin(value)
Getter	get_drag_margin()

Right margin needed to drag the camera. A value of 1 makes the camera move only when reaching the edge of the screen.

drag_margin_top

Top margin needed to drag the camera. A value of 1 makes the camera move only when reaching the edge of the screen.

bool drag_margin_v_enabled

Default	`false`
Setter	set_v_drag_enabled(value)
Getter	is_v_drag_enabled()

editor_draw_drag_margin

Default	`false`
Setter	set_margin_drawing_enabled(value)
Getter	is_margin_drawing_enabled()

If true, draws the camera’s drag margin rectangle in the editor.

bool editor_draw_limits

Default
Setter	set_limit_drawing_enabled(value)
Getter	is_limit_drawing_enabled()

If true, draws the camera’s limits rectangle in the editor.

editor_draw_screen

Default	`true`
Setter	set_screen_drawing_enabled(value)
Getter	is_screen_drawing_enabled()

If true, draws the camera’s screen rectangle in the editor.

int limit_bottom

Default	`10000000`
Setter	set_limit(value)
Getter	get_limit()

Bottom scroll limit in pixels. The camera stops moving when reaching this value.

limit_left

Default	`-10000000`
Setter	set_limit(value)
Getter	get_limit()

Left scroll limit in pixels. The camera stops moving when reaching this value.

int limit_right

Default	`10000000`
Setter	set_limit(value)
Getter	get_limit()

Right scroll limit in pixels. The camera stops moving when reaching this value.

limit_smoothed

Default	`false`
Setter	set_limit_smoothing_enabled(value)
Getter	is_limit_smoothing_enabled()

If true, the camera smoothly stops when reaches its limits.

int limit_top

Top scroll limit in pixels. The camera stops moving when reaching this value.

offset

Default	`Vector2( 0, 0 )`
Setter	set_offset(value)
Getter	get_offset()

The camera’s offset, useful for looking around or camera shake animations.

float offset_h

Default	`0.0`
Setter	set_h_offset(value)
Getter	get_h_offset()

The horizontal offset of the camera, relative to the drag margins.

Note: Offset H is used only to force offset relative to margins. It’s not updated in any way if drag margins are enabled and can be used to set initial offset.

Default	`0.0`
Setter	set_v_offset(value)
Getter	get_v_offset()

The vertical offset of the camera, relative to the drag margins.

Note: Used the same as .

Camera2DProcessMode process_mode

Default	`1`
Setter	set_process_mode(value)
Getter	get_process_mode()

The camera’s process callback. See .

bool rotating

Default	`false`
Setter	set_rotating(value)
Getter	is_rotating()

smoothing_enabled

Default	`false`
Setter	set_enable_follow_smoothing(value)
Getter	is_follow_smoothing_enabled()

If true, the camera smoothly moves towards the target at smoothing_speed.

smoothing_speed

Default	`5.0`
Setter	set_follow_smoothing(value)
Getter	get_follow_smoothing()

Speed in pixels per second of the camera’s smoothing effect when smoothing_enabled is true.

zoom

Default	`Vector2( 1, 1 )`
Setter	set_zoom(value)
Getter	get_zoom()

The camera’s zoom relative to the viewport. Values larger than Vector2(1, 1) zoom out and smaller values zoom in. For an example, use Vector2(0.5, 0.5) for a 2× zoom-in, and Vector2(4, 4) for a 4× zoom-out.
