So when it comes to the incredibly complicated and extremely advanced fishing mechanics, you have 2 buttons to press: Left Click and then Right Click. When you’re holding the Fishing Rod, just hold Left Click to see the draw distance circle zooming in. The further it zooms in, the further the cast. BUT, the further the cast, the more stamina you’ll be using.
Once you’ve cast your line, if you notice there are NO fish in the area where your bob is, there’s no point to staying there, cause sometimes you’ll get lucky and fish will come, but others you’ll just stand there for all eternity. All up to you in the end. BUT once that fish finally does come, you’ll see an animation play where the bob will dip into the water, a splash will be made, and that’s when you hit RIGHT click.
Once the fish is hooked, it doesn’t just THROW the fish at you like it does in Minecraft, this part takes HEAPS of Stamina, so make sure you’ve eaten a lot of good stamina meals before Fishing. Holding down Right Click will reel in the fish, using up Stamina all the while. I’ve tried giving the fish some line to gain back some Stamina, but it always ends up escaping, so I figured you just gotta reel it all the way in. Remember, the further your cast, the further it is to reel in and the more Stamina you’ll need.
