This is insane how one person can simulate water physics on a cpu based game better than most modern day games can.

[@nocturne6320]

He's using an old NVidia library that's doing the simulation, the hard work from his side is actually integrating it with GMod. The reason why pretty much no games use this tech is because it's very expensive and the physics isn't 100% stable. GWater is capped at 100k particles and you can see that it isn't enough to even fill up that small area he walled off, sure, you can increase the limit to 1 mil, but only better hardware can handle those values. So if you wanted to use this in an actual game you would be very limited by the scale of the simulation, because either you'd use small, but realistic particle size and be constrained to only using the sim in very small areas, eg. A single pool, or you'd have to blow up the particle size, which would look bad and you'd still only fill up a small pond at best. It's simply not usable for anything cool

[@clownintraining5944]

@@nocturne6320 it's usable for small bodies of water, so if your game takes place in an urban environment, you could have bathtubs filled, or crates, or you could have a small pipe puzzle. you definitely *can* work with this.

[@nocturne6320]

@@clownintraining5944 In short, it's not worth the performance hit. While FleX, the NVidia library GWater uses is not strictly NVidia cards only, it does rely on CUDA (and probably has a different implementation for AMD), which is not available on AMD cards and that could mean that the physics behaves slightly differently, which can be a big deal for gameplay. Another is that physics cannot have a "quality" slider. With graphics, you can add in expensive stuff like raytracing into your game, because if someones hardware cannot run it, they can just disable it with no impact on the gameplay, this is not possible for physics, if some hardware wasn't powerful enough to run the simulation, then the game might not even be playable on that system (especially a bad scenario for console development). And finally the performance. For what small details you can do with this, it's not worth it. Why have a realistic water sim of a duck pond when you could instead use that performance to render at overall higher quality, or fit more stuff on the screen.

[@plinyvicgames]

games used to do this. the only game in recent history i even remember that simulated fluids was borderlands 2, and it was still locked to nvidia GPUs

@@iga.P For me its more about the huge amount of real time water, there are only two others games that come to mind that do this at some capacity and very little... Trine 2 and Worms Revolution, from 2011 and 2012 respectively (Surely there are more, but i personally only know these two) I remember playing these years ago and thinking how cool future games would be, lol poor kid.. if only games had continued to experiment and BEING GOOD :(

you can already make pirate ship wars in Gmod, there's a tool to edit buoyancy. you can use wooden breakable parts and when parts gets destroyed the ship loses buoyancy and ends up sinking

It's really coming along, seeing far how it's come from GWater 1 to GWater 2 has been really cool, "night and day" doesn't even come close to describing it.

[@NoSyntax3]

A few years ago I saw a discord mod in the Fun With Ragdolls discord say that real time fluid simulation would be impossible. This is incredible.

[@StiekemeHenk]

Okay, we need some voiceover of this. There's no way you didn't have a TON of issues while getting this to work.

[@pennyjim5671]

The description does say it was reused from gwater1. So while I don't doubt there were some _fun_ bugs to fix, I'm sure it wasn't that hard. Still not *easy*, just not that hard.

[@Gaood.]

No shit Sherlock

[@StiekemeHenk]

@@Gaood. I literally shit every day Sherlock

[@Meetric1]

it was actually pretty easy since it was mostly just reused code. The hardest part was getting the server Lua instance from the client (to avoid networking / exploitation unlike gwater1), which did take a bit

[@StiekemeHenk]

@@Meetric1 I'm a software development student (apps/sites/servers) so client/server problems on this level aren't something I deal with often. I'd love to hear more about it!

you did it now just sound and a more cooler looking underwater effect and thats it
