I was interested and wanted to see how much the animations burn CPU and whatnot, so I cloned the repo and went to try to build the demo but everything went to hell. The build environment is some .net thing written in C#. It comes with a "bootstrap.sh" file to get it going that immediately fails, even after installing the dotnet development environment. I fiddled around with it for some time before giving up because I was hitting an error about a Targeting Pack that was going to require me to hit a Microsoft website to fix.

But the README says the build process it just a couple of files so I figured I could just build it by hand. This involved downloading a couple more repos from the author's repo and setting up some symlinks, includes, and defines that I figured out through trial and error, but in the end I was not successful in getting the demo to build. I tried a combo of SDL2 and OpenGL3 but it bombed out with a C++ error about too many initalizers. The only good news is that I was able to cleanly build the demo_im_app code, but the main requires the ImPlatform which appears to be buggy.

Update: I figured out that you need to run a git submodule update command first. The shell script is supposed to tell you this but it is broken. This does a bunch of work but then dies because g++ doesn't stick the string ".exe" on the end of executibles. Also, the script looks in the wrong place for the output. A few text fixes in the bootstrap.sh and generate_projects.sh files and it gets to a point where the build is dying due to not having "main" or "sharpmake" objects in the current context, whatever that means. I don't know enough about C# to go further, especially for what was supposed to be a quickie 10 minute test. I'm hoping someone else figures this out and updates the repo.

You should be run bootstrap and generate_project script. For ImPlatform I didn't have setup to tests all permutations. For ImPlatform you should try glfw-opengl3 or Win32-dx11 for windows.

bootstrap.sh is buggy. The message about running the git submodule command is never shown because the directory already exists in the repo.

It also looks specifically for .exe files, when a linux compiler won't append that suffix.

It also looks in the x64 directory, which was not created when I ran it.

For some reason even though I have dotnet 8.x installed it compiled with dotnet 6.x and complained about 6.x being obsolete.

The generate_project script also looks for a .exe file, but even when stripped off the process fails with namespace errors for 'main' and 'sharpmake'. These errors occur in a temporary file unfortunately so they're hard to investigate.

		Otherwise if you are already a Dear ImGui user: https://news.ycombinator.com/item?id=46111925 Just add 2 files im_anim.h/cpp in your project and you're done! And if you want the demo add demo_im_anim.cpp and call ImAnimDemoWindow(). Don't over complicate things.

For perf usage the demo for 100+ of anims (clip, tween, stagger, ...) it cost between 2-5 ms depending on your computer (that's not mean a proper benchmarks).
