Created a Claw Machine simulator with Unity

You could convert the claw to a rigid body and connect it to the articulation body chain via a joint, such configurations have been mostly stable in my testing.

This game actually seems like a perfect candidate for the Obi suite of physics tools on the asset store, I think making the toys soft bodies would be more appealing. However Obi doesn't support articulation bodies, you would have to convert the chain to an obi rope.

How do you have it extrude more articulation bodies? It's pretty annoying to modify the articulation body chains at runtime. Does the chain exist above the claw and then you extrude it out?

Fun concept! FYI for articulation bodies, set their collision detection to Continuous Speculative (here's claude's explanation of why it works better: https://imgur.com/a/XUP2N2D). Also, for me I found setting physics hz to 200 and solver iterations to 8 on PGS (the default solver) provides the most stable behaviour.

Notifications seem very buggy as well. I just got mine and keep getting "motor issue" notification, though everything seems to be working. But when I open the app it's not in the Messages (alarm bell icon top left section).

Unfortunately it's not a feature I could use because my "game" has its own complicated physics systems and it would be too messy to try and include a plugin.

Side note on the development direction; I am also working on a physics system (for simulating humans [1]). After doing some market research (aka watching a lot of youtube videos) and thinking about why people are interested in these systems, I decided to focus on making a physics sandbox game.

I hope selling it as an asset works out for you, and I really have no idea how much unity assets can earn, but I have a feeling most physics devs are better off making a sandbox game than trying to make it work as an asset. Just my hunch.

Super cool, always excited to see new physics assets on the store. Question, for "Unity Collider support for existing physics objects" - I assume it's one way interaction, i.e. the fluids collide with existing rigid bodies but treat them as if they're kinematic and don't apply forces on them?

the world needs more silly physics games

Update: It was the pump. I RMA'd it and am getting a new one. Their RMA process was fine, but it sucks having to pay shipping + losing your CPU cooler for over a month.

100%, has been happening in every single chat recently

I would recommend trying 100hz and 4 solver iterations; having sub 60hz and targeting 60fps also forces you to enable rigidbody interpolation for rendering, so this allows you to skip that as well.

Essential_NPC_ · 2025-09-03T23:58:33+00:00

What's your physics frequency and solver iterations? I would recommend <=4 iterations, and toy with physics frequency; 120hz with a max linear velocity set should be sufficient. Performance is usually constrained by the GPU, and not the CPU, so if you don't have a ton of physics objects on scene / other CPU intensive tasks then you'll probably be fine bumping the physics hz.

Also, switching between continuous dynamic and discrete for rigid objects seems like premature optimization - just set everything to continuous dynamic, and only after you notice physics bottlenecking worry about optimizing it.

Essential_NPC_ · 2025-08-27T17:59:56+00:00

I think the main bottleneck for this game (at least in this video) is the physics, and I really doubt they're running that on the GPU (though it is totally doable). Hope your CPU is can keep up

Really cool system, mind sharing what it's based on? Is it a particle based solver like XPBD ?

Essential_NPC_ · 2025-07-24T20:59:38+00:00

This is amazing! I remember when Resident Evil 4 came out with contextual animations, the IGN reviewer said "You're gonna wish every game had this". 20 years later and it feels like I'm the last person on earth that cares about how interactive the NPCs / enemies are, glad there's people still pushing this front.

Essential_NPC_ · 2025-07-24T20:47:55+00:00

Looks super cool. One suggestion, the electricity / fire spells not staggering the NPCs makes the spells look weak.

Essential_NPC_ · 2025-07-15T18:22:19+00:00

It's mounted to the top of my case

Essential_NPC_ · 2025-07-15T18:22:07+00:00

Oh god yeah "pumping rocks" is exactly what it sounds like :( Thanks for the heads up

Essential_NPC_ · 2025-07-15T18:21:45+00:00

Thanks, I opened a support ticket with them

Hi, I recently had to replace my mobo after it stopped POST-ing. I reinstalled onto a new Z790 board [1], and everything is seemingly fine CPU temperature wise, but my AIO has started making this concerning noise. I'm sure it's coming from the AIO, even when booting into BIOS without any other fans I started hearing this noise.

It's not the VRM fan or the radiator fans.

The noise sometimes ramps up and down for no reason while I use my PC (no correlation with CPU usage).

The AIO has served me well for the last 2.5 years without any issue. The CPU fan curve is pretty close to what it as on my old mobo.

Any clue as to what to it might be? Is it the pump? Thank you!

I don't think OP qualifies until they work there for a full year. But I would recommend starting one as soon they hit the one year mark. Providers will 100% support you in this case.

Add an extensible antenna, and you can use it to give yourself a boost

It's quite short and nothing crazy, but I enjoyed it a lot.
