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.
[b]Note:[/b] 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 [member ProjectSettings.rendering/limits/buffers/canvas_polygon_buffer_size_kb] and [member ProjectSettings.rendering/limits/buffers/canvas_polygon_index_buffer_size_kb].
If [code]true[/code], attempts to perform antialiasing for polygon edges by drawing a thin OpenGL smooth line on the edges.
[b]Note:[/b] 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 [url=https://github.com/godot-extended-libraries/godot-antialiased-line2d]Antialiased Line2D[/url] add-on then create an AntialiasedPolygon2D node. That node relies on a texture with custom mipmaps to perform antialiasing.
The polygon's fill color. If [code]texture[/code] is defined, it will be multiplied by this color. It will also be the default color for vertices not set in [code]vertex_colors[/code].
Amount to offset the polygon's [code]texture[/code]. If [code](0, 0)[/code] the texture's origin (its top-left corner) will be placed at the polygon's [code]position[/code].
Texture coordinates for each vertex of the polygon. There should be one [code]uv[/code] per polygon vertex. If there are fewer, undefined vertices will use [code](0, 0)[/code].
Color for each vertex. Colors are interpolated between vertices, resulting in smooth gradients. There should be one per polygon vertex. If there are fewer, undefined vertices will use [code]color[/code].
