I added a small toast notification that activates when you score in training, like bakkesmod used to add it to text chat. It also activates when you hit the crossbar so you can feel even more remorseful that your beautiful musty didn’t go in :)

I actually got the program to segfault while making it. egui’s external viewport api is kinda funky… there are two modes, immediate and deferred, and immediate is supposed to be easier to use. However, when I tried to use immediate mode, it panicked saying that the egui backend was implemented incorrectly. So I switched to deferred, and it gave me the segfault. There were 3 things I had to do:

1. I stored all active toasts in a Vec, and render them in the external viewport every frame. When one should disappear, it uses Vec::retain to remove old ones. However, this doesn’t do any cleanup, meaning the viewport would go bonkers and crash the application. So, I had to close the viewport first.

2. Calling ui.ctx() from the viewport made a segfault, probably my fault but I couldn’t figure out how to resolve it so I ended up just sending Viewport::Close from the main loop.

3. Even if I sent Viewport::Close from the main loop, it still gave the weird error. So, I resolved it by adding a small delay from after it should close, which is when it sends the Viewport::Close command, and when it’s actually removed from the Vec of toasts.

Well, I did all that, and it was working, but there was a really weird bug where it would lag the whole system while opening/closing. So, I switched from immediate to deferred viewport mode, and it stopped happening!

I hit my first powerful airdribble musty with it on, it was around 105kph, and a total fluke. I wish I had gotten it on recording.
