Group Experiment Project 1

[robertlong]

During our meeting on February 2nd we decided to run an experiment as a group to help explore what possible APIs we could specify for exposing simple scripting operations. People are invited to create their own project using their tech/engine of choice to implement a demo of their WASM ABI design. Alternately you can submit code that defines this WASM ABI and examples of how it might be used.

Requirements

For the ABI requirements we settled on 1 input and 3 outputs to the WASM environment.

Input

• Collision event / state This could be a boolean property or means of setting/exposing a callback function that handles collision events. You should define a means of determining if an object is colliding with another object or not. If you are creating a demo, you need a way of showcasing collision events. This could be a player colliding with a collision volume or a rigid body falling and colliding with a collision volume. Whatever method you'd like to highlight this property changing and the change in outputs.

Output

• Audio clip playing/paused state This could be a boolean property or function for setting the state of an audio clip's playing/paused state. If you are creating a demo you need a way of playing back audio and responding to this playing/paused state.
• *Material color This could be a vec3 (RGB) or vec4 (RGBA) property or a function for setting the color of a specific material.
• Transform This could be a set of functions, a struct, or anything else you can think of for defining the position / rotation / scale / parent / children of a node in a scene graph. You should design an ABI that showcases how you might represent and mutate transforms

Important Dates

We'll run this experiment until we decide as a group that we have gained the knowledge we needed, however there will be check-in's / milestones at the weekly WASM group meetings.

• 1st Check-in (Tuesday Feb 8th)
• 1st Milestone (Tuesday Feb 15th)

At check-ins you can give us a quick update on how your project is going and ask a few questions if needed. During milestones we'd like to see a quick presentation (slides, a screenshare of your code editor, or a demo) showcasing your work.
