This example project uses the Pen extension and the random block to generate and draw Super Simple Scripted Scrolling Scenery. Click to change the scroll speed. Click again to hide the slider. There's a loop in the stage code which continually broadcast the Tick message. Each Tick, the Pen sprite uses information in the Trees and Bushes lists to draw the scenery. If you want to change how things are drawn, this is the sprite to change. Also each Tick, the Trees sprite and the Bushes sprite update their counters, to see if it's time to generate new stuff in the scrolling scenery. The x position, random color and random size of Trees and Bushes are stored in the lists with the same name. If you want to change the frequency of trees or bushes, or the variation of size or color, these are the sprites to change. These sprites also purge the lists of items which have scrolled to the left of the screen. All code by me (@kriblo).
