Render Targets

Smooth-scrolling render-target

Here we have switched from 1-pixel-wide solids to lines.   In order to avoid re-drawing dozens of lines, we first draw the entire playfield onto a render-target which is 3-screens wide, then we treat that render-target as a sprite, rendering a subset 1-screen wide and offset by our imaginary X position
