Fun fact, I tackled this very challenge about a month ago, wanted to make a simple pool game for my kids. I thought Unity's physics would have things covered, but nope -- what a fail that was. I applaud your patience, I stopped working on it half-way.

Yeah it's a slog for very mediocre results 😂

i can't wait to use this fact!

Got to love the cue ball going full force into the unstoppable wall that was the, uhm, other balls? Not too well versed in the language of pool…

Decreasing the physics update time, as well as changing the physics materials would help you get a better result and people would actually learn something by watching :)

Hello, have you ever worked on a billiards project with unity? We have a problem with physics, it's not realistic

@b3agz!!! Good to see you again! ❤

Change the collider at the end of the cue to be a long capsule along the length of the cue rather than a sphere collider, as well as use continuous dynamic on the rigid bodies. You could alternatively, instead of a collider, use a ray cast so that the end of the cue always measures it’s displacement each physics update and then ray casts along this displacement (or sphere cast) and then applies a force to the cue ball proportional to the displacement/physics update time (velocity that frame)

Interesting, because the most popular 8 ball pool mobile game now was made using Unity.

It's not impossible that they used built-in physics but I would be very surprised if they didn't build something custom inside of Unity.

man, background music's the same as in Escapist's Cold Take series, threw me off a bit ) cool video, yeah )

Cool little video. I know the physics seems janky, but it could have been the settings on the rigid bodies. Default values uses discrete collision detection which is great for a rigidbody hitting a static item, but not so great for multiple rigidbody collisions. In this case Continuous Dynamic would have been a great choice and change the interpolate mode to interpolate. Making sure the mass/drag/angular drag of the items resembles real world, then the behavior is typically fairly close as well. The only thing that I have to change sometimes that isn't really a "default" option is the physics time step. With fast moving objects, sometimes the time step is too large and needs to be decreased for smoother movement. But this is kind of a rare occurrence.

Do you think it's possible to use default physics for poool game?

@@mikhailhumphries I would think so.

How would you go about implementing more realistic physics?

Essentially by faking it. Write specific code to move the balls realistically. Realistic physics across a whole game would be too expensive to process so the core physics engine is just kind of a rough sketch of real world physics. For a super specific small situation like pool balls (or golf or tennis or football) you can do more realistic physics

No syntax-heighlight..? :D crazy dude.. :P

Poker game next 😁
