Category: Section E

For this project I wanted to create a game, but not one of those kinds where you feel anxious and competitive while playing the game.

So I created this game where you can enjoy the winter scenery and a cute dog running while given a bit of an entertainment of being able to move around the dog and its sled to collect the presents.

 

How to:

Use the left/right arrow keys to move around the dog and its sled.

Use the space bar to generate more presents (will be falling from the sky)

NEVER HOLD THE KEY DOWN!!!

The sliding motion of the presents was to re-enact the real time inertia of the objects.

Anna Gusman and I created a therapeutic garden landscape that grows when it’s sung to. We chose to collaborate on this project because we were both super eager to explore p5’s comprehensive and lauded sound library. We thought that sonic interactions and audiovisual expressions would be great domains to explore by utilizing this tool.

Initially, we brainstormed ways by which people could see themselves “reflected” in a dynamic digital environment. By activating and scaling properties of the internal mic, we could poise the voice of an audience as the actuator of a captivating and therapeutic experience. The scene we designed contains four dynamic elements: recursion, flocking behavior, algorithmic curves and a particle system. Respectively, these would inform the emergence of natural objects like trees, wind, the moon and stars. Each of these dynamic elements are initiated by a singing voice and continue to grow as the viewer continues to sing! While some elements with more exposure to sound multiply, others express continued metamorphosis within themselves.

For my final project, I wanted to create a game with a fun ambiguous character. In a way, the game is like a fight between an organic shape and geometric shapes. It’s slightly different from my proposal but I like the way it turned out. It uses a modified version of the generative landscape functions, making the terrain (falling objects) fall downwards instead of sideways. It was difficult to modify the code so that the shapes would fall in a way that was relatively even, and not in lines or waves. The character is done using a heavily modified version of the soft body code found on the p5.js examples.

The objective of the game is to clear the screen! The rings pop whenever the character touches them, but the character’s own color must match up with the color of the squares to eat them. To change the character’s color, the player must select Q, W or E on their keyboard.

For my project, I decided to stay with the theme I had developed throughout the semester with plane-based projects.

The objective of the game is to fly the plane onto the runway while avoiding mountains and lightning. Instructions for running the game are included.

I had a really hard time with this project. My original concept was perhaps more interesting but I had an extremely hard time executing it, so I pivoted my project to this secondary concept at the last minute. However, I had a lot of fun creating it, as well as working on the styling and themes of the splash screens in particular. I hope you enjoy it!

I decided to create a choose-your-own-adventure game! My initial idea was to focus on having no visuals—using only text and sound to guide the user through the story—but ultimately ended up using both visuals and text together, and just text on its own.

The story was difficult to write in its own right and I don’t claim that it is that good, but the point of this game is that most of the endings the user runs into will build on the story of the game. I decided to focus mainly on using objects (since that was the most difficult part of this class for me and I wanted to make sure I ended this class with the knowledge of how to use them).

Brief summary: Jumping Dots, Turtle, and Turquoise Starfield.

For my final project, I took the advantage of making my canvas a space in which the viewers could momentarily be immersed in. As I believe that the  strength of interactive artworks is their ability to allow the audiences to create unexpected changes, I allowed the environment of my work to be altered by the viewers. Despite the changeable environment, however, I also focused on achieving a sense of visual consistency through the usage of coherent colorations and forms.

Conflicting factors coexist in my work; the space is chaotic yet orderly, inviting yet daunting, random yet systematic. Coexistences such as these were merged in creating this single work. I hope you enjoy momentarily being immersed in this space I created!

I also filmed projections of my work to experience its amplified effects outside of my screen.

and here are screenshots of various possible outcomes:

Here is a video of a slight alteration of the piece. I liked how it looked (and reminded me of Christmas and our imminent winter break!), so I decided to include it.
