Unity 6 "empty" web build file sizesThis short post by Defold people about "empty project build size" comparison between Defold, Unity and Godot(twitter,mastodon) sparked my interest.
It is curious that Godot builds seem to belarger than Unity? Would not have expected that! Anyway.
Away more extensive Unity "web" build comparison and analysics is over athttps://github.com/JohannesDeml/UnityWebGL-LoadingTestbut here are just my short notes in trying out Unity 6 (6.0.23 - Oct 2024).

Apple Metal Shader Compiler Cache locationAs pergfx-rs/gfx#3716 (comment) :
macOS has a system shader cache at $(getconf DARWIN_USER_CACHE_DIR)/com.apple.metal
On my MacBookPro that is under/var/folders/52/l9z1nqld5yg99tb_s3q6nyhh0000gn/C
- System shaders:
/var/folders/52/l9z1nqld5yg99tb_s3q6nyhh0000gn/C/com.apple.metal - Blender shaders:
/var/folders/52/l9z1nqld5yg99tb_s3q6nyhh0000gn/C/org.blenderfoundation
Delete all the folders in there to clear the cache.

| I get changes from version control, about a dozen files changed (1 commit), then I open Unity. | |
| It takes about one minute to open the project. The project Assets is 23GB (143k files), it also references | |
| some local packages which is 8GB (63k files). Large part of project assets folder is custom data not used | |
| by Unity's import pipeline ("baked" files for game, under StreamingAssets folder, 13GB, 47k files). | |

| // just going through Data/Managed/UnityEngine.xml in Unity 2023.1.0a22, letters A to C, | |
| // searching for "[]" finds these public APIs that take arrays as parameters. Then next to | |
| // them I looked whether they have a List<> or NativeArray<> variants. Some do have List<>, | |
| // very few have native array. Most of them would be good candidates to take a Span<T>, | |
| // in some cases that might reduce the need for also having "an integer offset and number of items" | |
| // arguments that some (minority) of them do. | |
| // | |
| // This is only A..C so far, or maybe like 10% of the UnityEngine.xml API. UnityEditor.xml probably | |
| // has a ton of similar ones :) |
