Enumerations

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
CAMERA2D_PROCESS_IDLE = 1

Description

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 CanvasItem based nodes.

This node is intended to be a simple helper to get things going quickly and it may happen often that more functionality is desired to change how the camera works. To make your own custom camera node, simply inherit from Node2D and change the transform of the canvas by calling get_viewport().set_canvas_transform(m) in Viewport.

Property Descriptions

AnchorMode anchor_mode

Setter	set_anchor_mode(value)
Getter	get_anchor_mode()

The Camera2D’s anchor point. See ANCHOR_MODE_* constants.

bool current

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.

Node custom_viewport

Setter	set_custom_viewport(value)
Getter	get_custom_viewport()

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

float drag_margin_bottom

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

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. Default value: true.

float drag_margin_left

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

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.

float drag_margin_top

Setter	set_drag_margin(value)
Getter	get_drag_margin()

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

Setter	set_v_drag_enabled(value)
Getter	is_v_drag_enabled()

If true, the camera only moves when reaching the vertical drag margins. If false, the camera moves vertically regardless of margins. Default value: true.

bool editor_draw_drag_margin

Setter	set_margin_drawing_enabled(value)
Getter	is_margin_drawing_enabled()

If true, draws the camera’s drag margin rectangle in the editor. Default value: false

bool editor_draw_limits

Setter	set_limit_drawing_enabled(value)
Getter	is_limit_drawing_enabled()

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

bool editor_draw_screen

Setter	set_screen_drawing_enabled(value)
Getter	is_screen_drawing_enabled()

If true, draws the camera’s screen rectangle in the editor. Default value: false

int limit_bottom

Setter	set_limit(value)
Getter	get_limit()

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

int limit_left

Setter	set_limit(value)
Getter	get_limit()

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

int limit_right

Setter	set_limit(value)
Getter	get_limit()

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

bool limit_smoothed

Setter	set_limit_smoothing_enabled(value)
Getter	is_limit_smoothing_enabled()

If true, the camera smoothly stops when reaches its limits. Default value: false

int limit_top

Setter	set_limit(value)
Getter	get_limit()

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

Vector2 offset

Setter	set_offset(value)
Getter	get_offset()

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

float offset_h

Setter	set_h_offset(value)
Getter	get_h_offset()

The horizontal offset of the camera, relative to the drag margins. Default value: 0

float offset_v

Setter	set_v_offset(value)
Getter	get_v_offset()

The vertical offset of the camera, relative to the drag margins. Default value: 0

Camera2DProcessMode process_mode

Setter	set_process_mode(value)
Getter	get_process_mode()

bool rotating

Setter	set_rotating(value)
Getter	is_rotating()

If true, the camera rotates with the target. Default value: false

bool smoothing_enabled

Setter	set_enable_follow_smoothing(value)
Getter	is_follow_smoothing_enabled()

If true, the camera smoothly moves towards the target at smoothing_speed. Default value: false

float smoothing_speed

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

Vector2 zoom

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 2x zoom in, and Vector2(4, 4) for a 4x zoom out.
