Could probably cut the time in half too with some small changes to the shaders. Some other issues need to be ironed out then I need to update mesh re/building and implement temperature followed by updating the overall sim logic and cell data model

[sweenus987 @sweenus987]

Slowly moving the fluid sim to GPU and dayum it's so much faster! Full active sim area (3x3 world chunks) with 4 sim steps per run is only ~0.33 ms compared to hitting +10ms with a single full world chunk active and a single sim step #ue5 #indiegamedev #indiegame

@Pirat_Nation Reminds me of Folding@Home. Biggest issue though is paying enough, for example the UK has ridiculous energy prices compared to many other nations

@xmmiraa @grok Man if AI could respond with something like "iDK" then we know we've hit intelligent AI

Very quick implementation of conversion of water to ice using a "spell". Water doesn't support flowing over it so I think the next step is to rebuild a few things so water can flow and adding temperature for dynamic phase changing #ue5 #indiegame #indiegamedev

[sweenus987 @sweenus987]

@WizardRobin8046 On normal actors yes though the freeze I'm talking about is more turning the water to ice which will be a simple case of getting the effect area sim data, seeing what's there and changing the simulation element

[sweenus987 @sweenus987]

Narrowing down the feel for the gameplay, I quite like this so far. Also added basic UI, grenades and direct interaction with animated stamps, gonna add some basic magic casting next, a basic freeze I think #UE5 #indiegame #indiedev

@UTCompiler Does it run as a post-process pass?

[sweenus987 @sweenus987]

@threejs Would make a great dynamic wallpaper

@Pirat_Nation Aren't the boats Newells and not owned by Valve?

@dbagrat @60 Looking through the comments, what data is stored for the cloud, is just depth and then the NN handles the rest?

[sweenus987 @sweenus987]

@guycalledfrank @quinnfiddy The width is vastly different, are you zoomed in?

[sweenus987 @sweenus987]

@solana_bandit Ahhh, many thanks! Too many variations of shallow water simulations😅 But this looks great and the method sounds like it fits my current setup. Would you spawn particles if flow rate gets high enough, to kind of emulate spray?

[sweenus987 @sweenus987]

@solana_bandit Is there a any specific name for the method? I'm currently using a method that just stores height and uses vertical velocity for spreading waves but my current implementation is slow and doesn't work as well as I'd like

[sweenus987 @sweenus987]

Or find ways to really trim the amount of work I'm doing down

[sweenus987 @sweenus987]

And this is what I mean by a slow fluid sim - 10ms - despite parallelisation on the CPU, as more chunks process water, the time it uses grows massively. I either need to find a much better algorithm or push fluid sim to GPU which I think I'll try first

[sweenus987 @sweenus987]

Added the start of some actual gameplay, a bit of shooting, some particles and fluid interaction. Changed camera from ortho to persp so you can still see depth. Def going to need a different approach for fluid, it's too slow #UE5 #IndieGameDev #gamedev

[sweenus987 @sweenus987]

@shun_webdesign Give it some soft body physics and you have Cushion Simulator

[sweenus987 @sweenus987]

Updated the visuals, now uses a rough implementation of voxels (data is a 2D heightfield), a bit slow when the fluid starts to spread so I might need either a dedicated plugin or different solution #UE5 #IndieGameDev #gamedev
