Viewport¶

Inherits: Node < Object

Crea una sub-vista en la pantalla.

Descripción¶

A Viewport creates a different view into the screen, or a sub-view inside another viewport. Children 2D Nodes will display on it, and children Camera 3D nodes will render on it too.

Optionally, a viewport can have its own 2D or 3D world, so they don't share what they draw with other viewports.

If a viewport is a child of a ViewportContainer, it will automatically take up its size, otherwise it must be set manually.

Viewports can also choose to be audio listeners, so they generate positional audio depending on a 2D or 3D camera child of it.

Also, viewports can be assigned to different screens in case the devices have multiple screens.

Finally, viewports can also behave as render targets, in which case they will not be visible unless the associated texture is used to draw.

Note: By default, a newly created Viewport in Godot 3.x will appear to be upside down. Enabling render_target_v_flip will display the Viewport with the correct orientation.

Descripciones de Propiedades¶

bool arvr

Default	`false`
Setter	set_use_arvr(value)
Getter	use_arvr()

If true, the viewport will be used in AR/VR process.

bool audio_listener_enable_2d

Default	`false`
Setter	set_as_audio_listener_2d(value)
Getter	is_audio_listener_2d()

Si true, el viewport procesará streams de audio en 2D.

bool audio_listener_enable_3d

Default	`false`
Setter	set_as_audio_listener(value)
Getter	is_audio_listener()

Si true, el viewport procesará streams de audio en 3D.

Transform2D canvas_transform

Setter	set_canvas_transform(value)
Getter	get_canvas_transform()

La transformada del canvas del viewport, útil para cambiar las posiciones en pantalla de todos los CanvasItems hijos. Esto es relativo a la transformada global del canvas del viewport.

bool debanding

Default	`false`
Setter	set_use_debanding(value)
Getter	get_use_debanding()

If true, uses a fast post-processing filter to make banding significantly less visible. In some cases, debanding may introduce a slightly noticeable dithering pattern. It's recommended to enable debanding only when actually needed since the dithering pattern will make lossless-compressed screenshots larger.

Note: Only available on the GLES3 backend. hdr must also be true for debanding to be effective.

DebugDraw debug_draw

Default	`0`
Setter	set_debug_draw(value)
Getter	get_debug_draw()

El modo de superposición para la prueba renderizó la geometría con fines de depuración.

bool disable_3d

Default	`false`
Setter	set_disable_3d(value)
Getter	is_3d_disabled()

If true, the viewport will disable 3D rendering. For actual disabling use usage.

bool fxaa

Default	`false`
Setter	set_use_fxaa(value)
Getter	get_use_fxaa()

Enables fast approximate antialiasing. FXAA is a popular screen-space antialiasing method, which is fast but will make the image look blurry, especially at lower resolutions. It can still work relatively well at large resolutions such as 1440p and 4K. Some of the lost sharpness can be recovered by enabling contrast-adaptive sharpening (see sharpen_intensity).

Transform2D global_canvas_transform

Setter	set_global_canvas_transform(value)
Getter	get_global_canvas_transform()

La transformación del canvas global del viewport. La transformada del canvas es relativa a esto.

bool gui_disable_input

Default	`false`
Setter	set_disable_input(value)
Getter	is_input_disabled()

If true, the viewport will not receive input events.

bool gui_snap_controls_to_pixels

Default	`true`
Setter	set_snap_controls_to_pixels(value)
Getter	is_snap_controls_to_pixels_enabled()

Si true, los controles GUI en el viewport colocarán los píxeles perfectamente.

bool handle_input_locally

Default	`true`
Setter	set_handle_input_locally(value)
Getter	is_handling_input_locally()

bool hdr

Default	`true`
Setter	set_hdr(value)
Getter	get_hdr()

If true, the viewport rendering will receive benefits from High Dynamic Range algorithm. High Dynamic Range allows the viewport to receive values that are outside the 0-1 range. In Godot HDR uses 16 bits, meaning it does not store the full range of a floating point number.

Note: Requires usage to be set to USAGE_3D or USAGE_3D_NO_EFFECTS, since HDR is not supported for 2D.

bool keep_3d_linear

Default	`false`
Setter	set_keep_3d_linear(value)
Getter	get_keep_3d_linear()

If true, the result after 3D rendering will not have a linear to sRGB color conversion applied. This is important when the viewport is used as a render target where the result is used as a texture on a 3D object rendered in another viewport. It is also important if the viewport is used to create data that is not color based (noise, heightmaps, pickmaps, etc.). Do not enable this when the viewport is used as a texture on a 2D object or if the viewport is your final output. For the GLES2 driver this will convert the sRGB output to linear, this should only be used for VR plugins that require input in linear color space!

MSAA msaa

Default	`0`
Setter	set_msaa(value)
Getter	get_msaa()

El modo antialiasing de multisample. Un número mayor resulta en bordes más suaves a costa de un rendimiento significativamente peor. Un valor de 4 es el mejor a menos que se trate de sistemas de muy alta gama.

bool own_world

Default	`false`
Setter	set_use_own_world(value)
Getter	is_using_own_world()

If true, the viewport will use World defined in world property.

bool physics_object_picking

Default	`false`
Setter	set_physics_object_picking(value)
Getter	get_physics_object_picking()

Si true, los objetos renderizados por viewport se convierten en sujetos del proceso de selección del ratón.

bool render_direct_to_screen

Default	`false`
Setter	set_use_render_direct_to_screen(value)
Getter	is_using_render_direct_to_screen()

If true, renders the Viewport directly to the screen instead of to the root viewport. Only available in GLES2. This is a low-level optimization and should not be used in most cases. If used, reading from the Viewport or from SCREEN_TEXTURE becomes unavailable. For more information see VisualServer.viewport_set_render_direct_to_screen.

ClearMode render_target_clear_mode

Default	`0`
Setter	set_clear_mode(value)
Getter	get_clear_mode()

The clear mode when viewport used as a render target.

Note: This property is intended for 2D usage.

UpdateMode render_target_update_mode

Default	`2`
Setter	set_update_mode(value)
Getter	get_update_mode()

The update mode when viewport used as a render target.

bool render_target_v_flip

Default	`false`
Setter	set_vflip(value)
Getter	get_vflip()

If true, the result of rendering will be flipped vertically. Since Viewports in Godot 3.x render upside-down, it's recommended to set this to true in most situations.

ShadowAtlasQuadrantSubdiv shadow_atlas_quad_0

Default	`2`
Setter	set_shadow_atlas_quadrant_subdiv(value)
Getter	get_shadow_atlas_quadrant_subdiv()

La cantidad de subdivisión del primer cuadrante del atlas de las sombras.

ShadowAtlasQuadrantSubdiv shadow_atlas_quad_1

ShadowAtlasQuadrantSubdiv shadow_atlas_quad_3

Default	`4`
Setter	set_shadow_atlas_quadrant_subdiv(value)
Getter	get_shadow_atlas_quadrant_subdiv()

La cantidad de subdivisión del cuarto cuadrante en el atlas de las sombras.

int shadow_atlas_size

Default	`0`
Setter	set_shadow_atlas_size(value)
Getter	get_shadow_atlas_size()

La resolución del atlas de las sombras (usado para luces omni y spot). El valor se redondeará a la potencia más cercana de 2.

Nota: Si se establece en 0, las sombras no serán visibles. Dado que los viewports creados por el usuario tienen por defecto el valor 0, este valor debe establecerse sobre 0 manualmente.

float sharpen_intensity

Default	`0.0`
Setter	set_sharpen_intensity(value)
Getter	get_sharpen_intensity()

If set to a value greater than 0.0, contrast-adaptive sharpening will be applied to the 3D viewport. This has a low performance cost and can be used to recover some of the sharpness lost from using FXAA. Values around 0.5 generally give the best results. See also fxaa.

Vector2 size

Default	`Vector2( 0, 0 )`
Setter	set_size(value)
Getter	get_size()

Vector2 get_size_override ( ) const

Returns the size override set with set_size_override.

ViewportTexture get_texture ( ) const

Returns the viewport's texture.

Note: Due to the way OpenGL works, the resulting ViewportTexture is flipped vertically. You can use Image.flip_y on the result of Texture.get_data to flip it back, for example:

var img = get_viewport().get_texture().get_data()
img.flip_y()

RID get_viewport_rid ( ) const

Devuelve el RID del viewport del VisualServer.
