Description

Editor-only class. This is not present when running the game. It’s used in the editor to properly edit and position collision shapes in CollisionObject2D. This is not accessible from regular code. This class is for editing custom shape polygons.

Member Function Description

int get_build_mode ( ) const

Return whether the polygon is a ConvexPolygonShape2D (build_mode==0), or a ConcavePolygonShape2D (build_mode==1).

int get_collision_object_first_shape ( ) const

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

When build_mode is set to generate convex polygons, the shape shown in the editor may be decomposed into many convex polygons. In that case, a range of indexes is needed to directly access the Shape2D.

When build_mode is set to generate concave polygons, there is only one Shape2D generated, so the start index and the end index are the same.

int get_collision_object_last_shape ( ) const

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

Vector2Array get_polygon ( ) const

Return the list of points that define the polygon.

bool is_trigger ( ) const

Return whether this polygon is a trigger.

void set_build_mode ( int build_mode )

Set whether the polygon is to be a ConvexPolygonShape2D (build_mode==0), or a ConcavePolygonShape2D (build_mode==1).

void set_polygon ( Vector2Array polygon )

Set the array of points forming the polygon.

When editing the point list via the editor, depending on get_build_mode, it has to be a list of points (for build_mode==0), or a list of lines (for build_mode==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.

void set_trigger ( bool trigger )

Set whether this polygon is a trigger. A trigger polygon detects collisions, but is otherwise unaffected by physics (i.e. colliding objects will not get blocked).
