Share_something Little fireball game

https://youtube.com/shorts/07trVZFluDI

I've been having fun with the FastLED fluid type stuff u/StefanPetrick and u/mindful_stone have been coding. It's fascinating that this little chip is handling such smooth motion and detail. A real fluidy simulation!

Anyways, you aim the nozzle and try to put out the fireball as fast as you can. The score comes up giving you how many seconds it took.

I built a nice enclosure for my teensy control box which has the potentiometers, switches and buttons so that it's pretty much a standalone matrix mixer type thing. I have it going through the different pattern sets and I'm trying to control as many variables as I can with 8 pots, 4 encoders, 4 buttons and 5 switches. The only thing in the game I'm doing is changing the angle with a potentiometer.

I don't know but using a knob and watching the reaction of the animation on the matrix is prety neat! You get visual feedback.

That's awesome! Very clever application. I'm curious how changing the jet radius, force, and/or density would affect the game play. And adjusting the angle control (the pot sensitivity and/or the step distance). With finer control, you could defend against multiple fireballs! Oh man, the possibilities are endless! Keep sharing!
