I can't for the life of me figure out how to build a zig-zagging (Z-shaped) staircase using the half-width stairs blocks to create a path that allows one to walk up and down to different floors. I have normal grated walkway blocks that they need to connect to. I can't figure out how they're supposed to be pieced together. Can someone share some screenshots?

Here's a screenshot of my multi-floor building. I have grated catwalks at each level where there are doors. The red lines indicate the zig-zag design the staircase needs to have. I have a 1x2 block space for the stair system.
