So I made a macOS thing. It's a fidget spinner, but with a twist.

@grishka @samhenrigold "but with a twist"

[rmasoni@mastodon.social]

@grishka @samhenrigold How’s that even possible? lmao

[grishka@mastodon.social]

@rmasoni @samhenrigold the private API is CGSSetWindowTransform. It allows you to set an arbitrary affine transform on a window. There's also CGSSetWindowWarp that takes a mesh, this is the one Sam is experimenting with, it's used by the system for that genie animation when you minimize a window.

@[email protected] @[email protected] is the title bar still completely functional?

[rmasoni@mastodon.social]

@grishka @samhenrigold Ooh! That makes sense! Thanks for the explanation.

[grishka@mastodon.social]

@georgemoody @samhenrigold unfortunately not *completely*. The hit testing seems to be broken for dragging, and if you do manage to start dragging it, it would jump like 100 pixels. The buttons do work.

[grishka@mastodon.social]

@Crates @samhenrigold should be easy, didn't think of that, heh

[samhenrigold@hachyderm.io]

@grishka @Crates take it a step further, prevent the center from spinning but spin the rest of the screen around it

[samhenrigold@hachyderm.io]

@grishka @Crates (this might force you to disable SIP like I had to do today to hook into the global drag and drop manager)

[samhenrigold@hachyderm.io]

@grishka @Crates bad experience, can’t recommend it

[grishka@mastodon.social]

@samhenrigold @Crates oh this was me today trying to set up censorship bypass tools on my new router

Now available on Github! And the center part does not rotate. And the momentum now feels more like the real thing.

While it does run on older macOS versions, it glitches a lot on anything 10.x. Not sure why this happens but it might be related to how the window server draws shadows.

[grishka@mastodon.social]

Anyway, now that I'm done with this, I'm gonna go back to photo albums in Smithereen

[avali@social.avali.zone]

@grishka @samhenrigold omfg it's so cursed... I love it

Why does this API even exist? What uses it?

[grishka@mastodon.social]

@avali @samhenrigold the rotation I'm not sure anything uses (which is why it's glitchy on older OSes), but scaling is used plenty for spaces/expose. The mesh warp is used for the genie animation when minimizing windows and was used for modal sheets in 10.x when the sheet is wider than its parent window.

[theoparis@mastodon.social]

@grishka @samhenrigold This is so cool! I didn't even realize this was possible until now lol
