While ( jcv_delauney_next( & delauney, & delauney_edge ))ĭraw_line( delauney_edge. Even In this single script if you change the sides you can draw any polygon shape (Tria. Jcv_delauney_iter delauney = jcv_delauney_begin( & diagram ) In this tutorial you will learn how to draw Square Shape in Scratch. Answer: d) Use the Set Stage Color block. c) Right-click and select Change Background Color.

b) Drag a color from the palette and drop it on the stage. We modify the custom draw square block that we created in the previous video in order to draw any polygon. How can you change the background color of a project in Scratch a) Use the Change Backdrop Color block. This bit of code might be worth re-using in other projects. The polygon is done with a 72 times repeat, and then we restore the turtle to its original state. To center the polygon, however, we start by backstepping by half of that amount. Void draw_delauney( const jcv_diagram * diagram) Scratch - How To Draw Any Polygon With Code. Each side of that polygon will be r0.087 (the circumference of the circle is 2r, and 2/72 is about 0.087). If you want to draw triangles, or relax the diagram, // you can iterate over the sites and get all edges easily const jcv_site * sites = jcv_diagram_get_sites( diagram ) ĭraw_triangle( site -> p, e -> pos, e -> pos) Void draw_cells( const jcv_diagram * diagram) If all you need are the edges const jcv_edge * edge = jcv_diagram_get_edges( diagram ) ĭraw_line( edge -> pos, edge -> pos) Void draw_edges( const jcv_diagram * diagram) Jcv_diagram_generate( count, points, 0, 0, & diagram ) Memset( & diagram, 0, sizeof( jcv_diagram))
