Camera2D¶

Inherits: Node2D < CanvasItem < Node < Object

Camera node for 2D scenes.

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.

Cameras register themselves in the nearest Viewport node (when ascending the tree). Only one camera can be active per viewport. If no viewport is available ascending the tree, the camera will register in the global viewport.

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

Note that the Camera2D node's position doesn't represent the actual position of the screen, which may differ due to applied smoothing or limits. You can use get_screen_center_position to get the real position.

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 Camera2DProcessCallback:

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 AnchorMode constants.

bool current

Default	`false`
Setter	set_current(value)
Getter	is_current()

If true, the camera acts as the active camera for its Viewport ancestor. Only one camera can be current in a given viewport, so setting a different camera in the same viewport current will disable whatever camera was already active in that viewport.

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_bottom_margin

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 bottom edge of the screen.

bool drag_horizontal_enabled

Default	`false`
Setter	set_drag_horizontal_enabled(value)
Getter	is_drag_horizontal_enabled()

If true, the camera only moves when reaching the horizontal (left and right) drag margins. If false, the camera moves horizontally regardless of margins.

float drag_horizontal_offset

Default	`0.0`
Setter	set_drag_horizontal_offset(value)
Getter	get_drag_horizontal_offset()

The relative horizontal drag offset of the camera between the right (-1) and left (1) drag margins.

Note: Used to set the initial horizontal drag offset; determine the current offset; or force the current offset. It's not automatically updated when drag_horizontal_enabled is true or the drag margins are changed.

float drag_left_margin

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 left edge of the screen.

float drag_right_margin

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 right edge of the screen.

float drag_top_margin

Default	`0.2`
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 top edge of the screen.

bool drag_vertical_enabled

Default	`false`
Setter	set_drag_vertical_enabled(value)
Getter	is_drag_vertical_enabled()

If true, the camera only moves when reaching the vertical (top and bottom) drag margins. If false, the camera moves vertically regardless of the drag margins.

float drag_vertical_offset

Default	`0.0`
Setter	set_drag_vertical_offset(value)
Getter	get_drag_vertical_offset()

The relative vertical drag offset of the camera between the bottom (-1) and top (1) drag margins.

Note: Used to set the initial vertical drag offset; determine the current offset; or force the current offset. It's not automatically updated when drag_vertical_enabled is true or the drag margins are changed.

bool 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	`false`
Setter	set_limit_drawing_enabled(value)
Getter	is_limit_drawing_enabled()

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

bool 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, but offset can push the view past the limit.

int limit_left

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

Left scroll limit in pixels. The camera stops moving when reaching this value, but offset can push the view past the limit.

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, but offset can push the view past the limit.

bool 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.

This property has no effect if smoothing_enabled is false.

Note: To immediately update the camera's position to be within limits without smoothing, even with this setting enabled, invoke reset_smoothing.

int limit_top

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

Top scroll limit in pixels. The camera stops moving when reaching this value, but offset can push the view past the limit.

Vector2 offset

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

The camera's relative offset. Useful for looking around or camera shake animations. The offsetted camera can go past the limits defined in limit_top, limit_bottom, limit_left and limit_right.

Camera2DProcessCallback process_callback

Default	`1`
Setter	set_process_callback(value)
Getter	get_process_callback()

The camera's process callback. See Camera2DProcessCallback.

bool rotating

Getter	is_rotating()

If true, the camera view rotates with the target.

bool 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.

float 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.

Method Descriptions¶

void align ( )

Aligns the camera to the tracked node.

void force_update_scroll ( )

Forces the camera to update scroll immediately.

float get_drag_margin ( Side margin ) const

Returns the specified Side's margin. See also drag_bottom_margin, drag_top_margin, drag_left_margin, and drag_right_margin.

int get_limit ( Side margin ) const

Returns the camera limit for the specified Side. See also limit_bottom, limit_top, limit_left, and limit_right.

Vector2 get_screen_center_position ( ) const
