How to generate random numbers in egui?

[gravit22]

I tried to use rand library, but it seems like egui doesn't support it. What can I use instead?

I'm curious, can you elaborate a bit on what you tried to reach the conclusion that egui doesn't support rand? I'm not an expert but I don't see how that would work.

No. Only Egui project. When I compile it locally it works fine.
I don't use wasm for any other projects.

[lunabunn]

Right. Quick skim through the doc page I linked reveals wasm32-unknown-unknown w/ JS needs the js feature to be set. I imagine you didn't set this correctly?

[gravit22]

I have no idea.

Either way, AFAICT this has nothing to do with egui. It's just that getrandom doesn't support wasm32-unknown-unknown out of the box.

When I added this line to dependencies, everything works.
getrandom = { version = "0.2", features = ["js"] }
