It seems like most narrative games have some kind of drudgery built in. You know, some tedious and repetitious task that you absolutely must do if you want to succeed. In Stardew Valley, that thing is gift giving, which earns you friendship points just like in real life. More important than the giving itself is that each villager has preferences — things they love, like, and hate to receive as gifts. It’s a lot to remember, and most people don’t bother trying and just look it up in the wiki. Well, except for Abigail, who seems to like certain gemstones so much that she must be eating them. She’s hard to forget.
[kutluhan_aktar]’s villager gift preferences bot is a fun and fantastic use of OpenCV. This bot uses a LattePanda Alpha 864s, which is a single-board computer with an Arduino Leonardo built in. It works using template matching, which is basically a game of Where’s Waldo? for computers.
Given a screenshot of each villager in various positions, the LattePanda recognizes them among a given game scene, then does a lookup of their birthday and preferences which the Leonardo prints on a 3.5″ LCD screen. At the same time, it alerts the player with a buzz and big green LED. Be sure to check it out in action after the break.
In Animal Crossing, the drudgery amounts to pressing the A button while catching shooting stars. That’s not a huge problem for a Teensy.
