Tiny Starfield 🌠🖱 Mouseover to change view angle!

u/cantelope

innovative
u/lewdev

Thanks u/cantelope but credit definitely goes to u/KilledByAPixel for making "Tiny Starfield" so tiny (93b)!
u/lewdev

I found a similar amazing use of onmousemove with d/24231 by u/Joachim
u/magna

You can avoid having to initialize X and Y by hijacking existing globals you don't use like T and R.
u/lewdev

Great tip u/magna! I was thinking about that a lot to cut out bytes recently.

I love it!

I plotted (shittily) all 28 unary functions: d/32414
u/lewdev

Thanks u/cantelope I didn't know about that one. u/magna your remix is awesome. I didn't know about all of those single-argument functions in Math. There's so much more JavaScript to learn!
u/magna

u/lewdev thanks for the inspiration!

13attle TanKs #js13k please try my game submission! https://js13kgames.com/2024/games/13attle-ta…

u/lewdev

The tank in my game is blue or orange, but red was all I could manage in 140b! I really squeezed this one to get it to fit!
u/cantelope

fun game. good sounds, and excellent AI stuffs
u/lewdev

I apologize in advance, the game is hard. Move backwards to avoid their shots and then move towards them to take a shot and repeat. I do realize that it's not easy for most people to do this.
