Studying a Class on Fish

https://editor.p5js.org/Inkreas/sketches/c3c5g0BDQ

I successfully turned my fish into a class, so I feel satisfied for this week. I also used the sin movement that my teacher suggested, but after successfully teaching my fish to swim, I still want to have my fish move as if they are migrating or wander their own directions. I think I can try to solve this problem over time.

One solution to the movement problem I'm thinking of is coding a function that changes the angle of the first circle by 1 degree of rotation randomly. that way there will be slight adjustment in the direction of the fishes movement.

Other than that I have a lot of scattered thoughts on my project which include the following:

1. I feel that my code is too messy and too long. I want to clean it up, but I feel like I can't do so until I have all the code settled. I'm constantly changing, adding, and subtracting ideas to try to make an experience that I'm satisfied with.

2. I also worry about the processing ability for my sketch to run. It already started lagging with 10 fish, and I want to run about 100 fish.

3. I think my next goal might be to add images to each section of the fish. I think I'll put the image after each circle using the same x & y positions.

4. I really want to find a way to make the construction of the fish body a loop rather than hard code the entire process.

On an emotional level, I wonder if it's a natural feeling to want to rush the learning process, because I have a vision for the project, but feeling incompetent.
