Description
|
|
-----------
|
|
|
|
A Polygon2D is defined by a set of points. Each point is connected to the next, with the final point being connected to the first, resulting in a closed polygon. Polygon2Ds can be filled with color (solid or gradient) or filled with a given texture.
|
|
|
|
\ **Note:** By default, Godot can only draw up to 4,096 polygon points at a time. To increase this limit, open the Project Settings and increase :ref:`ProjectSettings.rendering/limits/buffers/canvas_polygon_buffer_size_kb<class_ProjectSettings_property_rendering/limits/buffers/canvas_polygon_buffer_size_kb>` and :ref:`ProjectSettings.rendering/limits/buffers/canvas_polygon_index_buffer_size_kb<class_ProjectSettings_property_rendering/limits/buffers/canvas_polygon_index_buffer_size_kb>`.

- void **set_antialiased** **(** :ref:`bool<class_bool>` value **)**
|
|
- :ref:`bool<class_bool>` **get_antialiased** **(** **)**
|
|
|
|
If ``true``, attempts to perform antialiasing for polygon edges by drawing a thin OpenGL smooth line on the edges.
|
|
|
|
\ **Note:** Due to how it works, built-in antialiasing will not look correct for translucent polygons and may not work on certain platforms. As a workaround, install the `Antialiased Line2D <https://github.com/godot-extended-libraries/godot-antialiased-line2d>`__ add-on then create an AntialiasedPolygon2D node. That node relies on a texture with custom mipmaps to perform antialiasing.
