VG_POLYGON(3) Library Functions Manual VG_POLYGON(3) NAME VG_Polygon -- agar-vg polygon entity SYNOPSIS #include <agar/core.h> #include <agar/gui.h> #include <agar/vg.h> DESCRIPTION VG_Polygon is a VG(3) node class which describes a filled polygon with VG_Point(3) entities as its vertices. INTERFACE VG_Polygon * VG_PolygonNew(VG_Node *parent) Uint VG_PolygonVertex(VG_Polygon *P, VG_Point *pt) void VG_PolygonDelVertex(VG_Polygon *P, Uint vtx) The VG_PolygonNew() function creates a new polygon entity attached to parent, without any vertices. VG_PolygonVertex() creates a new vertex using the existing VG_Point(3) pt. The index of the new vertex is returned. VG_PolygonDelVertex() removes the specified vertex vtx from the polygon. The function is a no-op if vtx is an invalid index. VG_PolygonSetOutline() disables filling of the polygon such that only its outline is displayed. Default behavior is to display a filled polygon. SEE ALSO VG(3), VG_Point(3) HISTORY The VG_Polygon class first appeared in Agar 1.3.3. Agar 1.7 December 21, 2022 VG_POLYGON(3)
