Month: December 2019

For our project, we decided to create an iPhone and allow for interactions with some of the apps typical users like to spend time on. Carly created the Snapchat app and added in a few filters that can be changed by hovering over the different circles.Tai recreated a music app where the user can choose different songs to listen to. Jai created the Instagram and Clock apps and also some of the initial images for the home screen. For instagram, the page mimics a person’s profile picture (his own), and for the clock app, each of the locations in different time zones represent their current live time. Putting together the code was difficult, but Carly went over the commenting and formatting, while Tai helped with debugging and combining all of the code.

Although this project was very fun to complete, we had a lot of glitches we weren’t expecting. Having multiple apps that all ran but did not interfere with each other was a bit of a struggle. Coding between three people made the code lengthy and since we had separately used the same functions, when we consolidated our codes, the functions were overriding each other. Also, for the music app, we originally had an entire album to play from, but by the end of the project our code was so long and took a while to load, that we had to cut out a lot of songs and shorten the length of the songs, so there are only 2 short sound clips that play if you click the “1” or “2” key.

tcliu-FINALPROJECT

Welcome to Crossy Chicken, my final project for 15-104! A tribute to the original Frogger, Crossy Chicken involves a chicken trying to reach her beloved egg. But to get there, the chicken must first cross two busy streets as well as a perilous bridge; can you get her back to her egg?

To play, use the WASD keys (W = Up, S = Down, A = Left, D = Right) to direct the chicken and follow the instructions on screen! Make sure you dodge all the cars and don’t let the chicken’s feet touch the water!

I had a fantastic time coding this project, and I’m proud of how I distributed the work. I broke my project down into phases, and I worked through them in the following order:

1. Character movement
2. Introducing cars
3. Adding roads
4. Creating the river and bridge
5. Adding the next 3 rows of cars
6. Losing screen
7. Winning screen
8. Reset button (ENTER)
9. Start button (SPACE)
10. Adding sounds

In the end, I wound up with what I felt was a very polished and complete game. I’m really happy that I was able to build a visually pleasing game with fun and retro graphics while using a multitude of elements from p5js. From objects, to loops, to sound, my game really has a bit of everything in it. The soundtrack (which is actually the original Frogger music!) adds an element of excitement and nostalgia, and the losing and winning sound effects complete the experience for the gamer. I hope you have a great time playing!

(*Note 2: as is typically the case with p5js, the sound is sometimes a bit glitchy on Chrome and certain other browsers. However, the implementation of sound is all correct, as can be seen in my code.)
