VisualServer¶
Inherits: Object
Server for anything visible.
Description¶
Server for anything visible. The visual server is the API backend for everything visible. The whole scene system mounts on it to display.
The visual server is completely opaque, the internals are entirely implementation specific and cannot be accessed.
The visual server can be used to bypass the scene system entirely.
Resources are created using the *_create functions.
All objects are drawn to a viewport. You can use the Viewport attached to the SceneTree or you can create one yourself with viewport_create. When using a custom scenario or canvas, the scenario or canvas needs to be attached to the viewport using viewport_set_scenario or viewport_attach_canvas.
In 3D, all visual objects must be associated with a scenario. The scenario is a visual representation of the world. If accessing the visual server from a running game, the scenario can be accessed from the scene tree from any Spatial node with Spatial.get_world. Otherwise, a scenario can be created with scenario_create.
Similarly, in 2D, a canvas is needed to draw all canvas items.
In 3D, all visible objects are comprised of a resource and an instance. A resource can be a mesh, a particle system, a light, or any other 3D object. In order to be visible resources must be attached to an instance using instance_set_base. The instance must also be attached to the scenario using instance_set_scenario in order to be visible.
In 2D, all visible objects are some form of canvas item. In order to be visible, a canvas item needs to be the child of a canvas attached to a viewport, or it needs to be the child of another canvas item that is eventually attached to the canvas.

Sets a viewport's camera.
Sets a viewport's canvas.
Copies viewport to a region of the screen specified by rect. If Viewport.render_direct_to_screen is true, then viewport does not use a framebuffer and the contents of the viewport are rendered directly to screen. However, note that the root viewport is drawn last, therefore it will draw over the screen. Accordingly, you must set the root viewport to an area that does not cover the area that you have attached this viewport to.
For example, you can set the root viewport to not render at all with the following code:
func _ready():
get_viewport().set_attach_to_screen_rect(Rect2())
$Viewport.set_attach_to_screen_rect(Rect2(0, 0, 600, 600))
Using this can result in significant optimization, especially on lower-end devices. However, it comes at the cost of having to manage your viewports manually. For a further optimization see, viewport_set_render_direct_to_screen.

void viewport_set_msaa ( RID viewport, ViewportMSAA msaa )
Sets the anti-aliasing mode. See ViewportMSAA for options.
Sets the viewport's parent to another viewport.
If true, render the contents of the viewport directly to screen. This allows a low-level optimization where you can skip drawing a viewport to the root viewport. While this optimization can result in a significant increase in speed (especially on older devices), it comes at a cost of usability. When this is enabled, you cannot read from the viewport or from the SCREEN_TEXTURE. You also lose the benefit of certain window settings, such as the various stretch modes. Another consequence to be aware of is that in 2D the rendering happens in window coordinates, so if you have a viewport that is double the size of the window, and you set this, then only the portion that fits within the window will be drawn, no automatic scaling is possible, even if your game scene is significantly larger than the window size.
Sets a viewport's scenario.
The scenario contains information about the ScenarioDebugMode, environment information, reflection atlas etc.
Sets the shadow atlas quadrant's subdivision.
Sets the size of the shadow atlas's images (used for omni and spot lights). The value will be rounded up to the nearest power of 2.
Sets the sharpening intensity for the viewport. 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 viewport_set_use_fxaa.
Sets the viewport's width and height.
If true, the viewport renders its background as transparent.
void viewport_set_update_mode ( RID viewport, ViewportUpdateMode update_mode )
Sets when the viewport should be updated. See ViewportUpdateMode constants for options.
void viewport_set_usage ( RID viewport, ViewportUsage usage )
Sets the viewport's 2D/3D mode. See ViewportUsage constants for options.
If true, the viewport uses augmented or virtual reality technologies. See ARVRInterface.
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. Viewport.hdr must also be true for debanding to be effective.
Enables fast approximate antialiasing for this viewport. 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 viewport_set_sharpen_intensity).
If true, the viewport's rendering is flipped vertically.
