It is very easy to be intimidated by the apparent complexity of some of the builds, especially if one were to examine the wiring diagrams such as the diagram to the computer/converter linked above. Those diagrams are more likely to make you go cross-eyed than glean anything useful from them. I used to be one of those individuals who would be easily intimidated and discouraged from engineering - when I'd examine wiring diagrams posted in various threads in the guides forum more than a year ago, I'd move right along since most of that stuff was too opaque for me to decipher. I'd enjoy watching the contraptions in action in the videos, but as far as understanding their internal workings, that was a different matter.What really turned things around was starting with the basics and working my way up. I'd experiment with wiring and with hoiks, building very basic mechanisms. For instance, it was quite a feat to build something as simple as a hoik loop which could propel the player endlessly around. Pretty soon I moved up to building hoik junctions - a hoik tooth in the middle of the junction can control whether a player or NPC will move in one direction or another depending on the actuation state of that tooth - very basic, but the foundation of much of the logic in Terraria engineering. I then found myself building increasingly complex mechanisms because once I understood the logic behind how those contraptions operated, the wiring became a straightforward consequence of that logic. I also noticed that many of the complex contraptions revolved around a few very basic mechanisms, such as hoik junctions and controlling paths that NPCs take.So I'd recommend three things for any budding engineers:1) Start by building basic mechanisms! Learn about hoiks and how they propel NPCs and players down hoik tracks, and then add some wires into the mix and experiment with hoik junctions. Put some pressure plates down on the hoik tracks and connect those pressure plates to various outputs (lights, teleporters etc.) and observe how it all works. To learn all about hoik basics, ZeorGravitas has posted a few excellent starter guides, the most important of which is the introduction to hoiks along with an exhaustive list of all possible basic hoik set-ups:I used this guide a lot when starting out!2) Download the worlds ZeroGravitas and I have offered (and that other engineers have offered as well) to get a first hand look at the more complex contraptions and how they function. Don't be put off by the wiring! Instead, it is much more important to focus on the logic behind the mechanisms - once the logic is understood, it becomes much easier to figure out the wiring. Watch our tutorial videos as well explaining the logic of the constructions. I personally have started recording a series of lengthy tutorial videos explaining my more complicated hoiktronics builds in an effort to make engineering less intimidating, and ZeroGravitas has already released several tutorial videos explaining in detail the fundamental hoiktronics components.3) Get involved on the T-MEC forums! We have some experienced engineers that can address any of your questions or concerns, and help out with your projects. T-MEC has a massive number of guides and other resources as well, and we add to the knowledge pool periodically via new threads once something new is discovered.With the wealth of resources at the budding engineer's disposal in the form of videos, written guides, world downloads, and forums dedicated to engineering, coupled with the massive design space opened up by the discovery of hoiks, Terraria engineering has never been more exciting to get into than right now!
