Click the green flag
HOW IT WORKS - When you click the green flag, it wipes out any old pen drawings and sets the pen size to 2 with a black color. Next, it goes into a forever loop where it: Clears all pen drawings to reset the previous frame. Sets up coordinates for eight points (x1, y1, ... x8), with x1-y4 making a square that’s roughly centered at the origin (from -50 to 50 on both axes). Assigns offset values offset_x and offset_y to 30. Calculates the coordinates for points x5-y8 by adding these offsets to the original points x1-y4, which creates a second square that’s shifted diagonally. Draws the first square by moving the pen through points 1 to 4 and back to point 1. Then it connects the corresponding points of the two squares with lines (like the edges of a 3D box): • from point 1 to 5 • from point 2 to 6 • from point 3 to 7 • from point 4 to 8 Finally, it lifts the pen and waits for 1 second before starting over. In short, the code creates a wireframe cube shape by drawing two offset squares that are connected at their corners. The cube gets redrawn every second.
