You should use 120 Hz, this gives more accuracy. go to Options (the gear at the upper left corner) , then Simulation, find the frequency slider and crank it up at 120 Hz. If you use more the scene will give a horrendous lag (ESPECIALLY on scenes with more objects)

Also try spawning only one ball big enough to cover the entire chamber, and USE VERY HIGH DENSITY ON EVERYTHING! like 250-500 kg/m2! This will make everything even better and it will give you 100x the power you have there

Use this script:

(e)=>{
scene.addcircle({
pos := pos;
radius := 0.09375;
restitution := 0;
friction := 0;
color := [1, 0, 0, 1];
density := 200;
collideset := 10;
timetolive := 0.2;
vel := entity.vel
})
}

You may need a killer to delete the balls, but try to figure out by yourself. Feel free to get inspiration from my own spawn engines! (most are on page 2 - 3)

The Linkage- Thanks, I'm glad to have some feedback on this! I was worried about getting a lot of hate for this, what with all the frustration about low quality scenes spamming algobox. I'll try the things you suggested and see what happens. Thanks!

Don't worry, the problem is with kids that post 15 scenes per day and get angry when you tell them not to.

Another little suggestion: use the grid ALL the time! And when you can, use simple shapes as boxes or circles, avoid polygons at all costs (even if you make boxes woth the polygon tool, that already is a polygon and it will have less accuracy and more lag)

I see, thanks for the tips!
