Make WebAssembly vector games using AssemblyScript

This is a tutorial video for making old-school vector based arcade games for WebAssembly. This is an intro tutorial, where I am using AssemblyScript and VectorEngine to create a simple vector animation in this tutorial.

Very cool Vector engine! I am a huge fan of vector games, and I go way back to the Atari days of the late 70s into the 80s, putting quarters into Asteroids, Tempest, Star War, Space Duel, Black Widow, etc. I have owned a full-size arcade Tempest cabinet since 1983. I would love to see a port of Atari classic vector games.

Thanks for making this! It worked for me. I changed the expression for scale to this so that it made more mathy sense, at least to me:
const minSize: f32 = 0.2;
const beatSizeChange: f32 = 0.02
const beatSpeed: f32 = 7;

const scale: f32 = (Mathf.sin(timeChange * beatSpeed) + 1) * beatSizeChange + minSize;

Amazing! Please create more videos like this using Assemblyscript!

It sounds quite promising, I haven't seen anyone write AS so it would be hard for me to start, shame there are no more videos here...

The reason why smaller numbers are faster is because a CPU typically has to load a set amount of bits (64 nowadays). For a 64bit cache line in the CPU you can load both numbers at once in one cycle, without wasting space.

Writing something in wasm only makes it faster if it's the part that performs computations (not I/O or HTML manipulation), and if you move to manual memory management in AS.
