I'm working on a way to display more information about all machines in-game, to reduce trial and error when coding. For example, just by looking at a conveyor belt, it is not immediately clear which direction is forward and which is backward.
Now, once you select a machine and zoom in a bit, a minimalistic, diegetic HUD element will appear and provide such information at a glance. Once you zoom out or deselect the machine, the HUD element subtly disappears.
Now you see immediately in which direction the conveyor will go, depending on positive or negative control values. Thus reducing the need for trial and error in your code. For other machines, it might be even more helpful. Here is a short sneak peak.
Happy Coding!
