CollisionObject2D is the base class for 2D physics collisionables. They can hold any number of 2D collision shapes. Usually, they are edited by placing CollisionBody2D and CollisionPolygon2D nodes as children. Such nodes are for reference ant not present outside the editor, so code should use the regular shape API.

Set the array of points forming the polygon.
|
||||
When editing the point list via the editor, depending on [method get_build_mode], it has to be a list of points (for [code]build_mode[/code]=0), or a list of lines (for [code]build_mode[/code]=1). In the second case, the even elements of the array define the start point of the line, and the odd elements the end point.

Return the index of the first shape generated by the editor.

When [code]build_mode[/code] is set to generate convex polygons, the shape shown in the editor may be decomopsed into many convex polygons. In that case, a range of indexes is needed to directly access the [Shape2D]s.
|
||||
When [code]build_mode[/code] is set to generate concave polygons, there is only one [Shape2D] generated, so the start index and the end index are the same.

Concave polygon 2D shape resource for physics. It is made out of segments and is very optimal for complex polygonal concave collisions. It is really not advised to use for RigidBody nodes. A CollisionPolygon2D in convex decomposition mode (solids) or several convex objects are advised for that instead. Otherwise, a concave polygon 2D shape is better for static collisions.
|
||||
The main difference between a [ConvexPolygonShape2D] and a [ConcavePolygonShape2D] is that a concave polygon assumes it is concave and uses a more complex method of collision detection, and a convex one forces itself to be convex in order to speed up collision detection.

Convex Polygon Shape for 2D physics. A convex polygon, whatever its shape, is internally decomposed into as many convex polygons as needed to ensure all collision checks against it are always done on convex polygons (which are faster to check).
