Regression

No

Stable type hash for the Component breaks when managed component data containing a Compute Buffer and Graphics Buffer is used

Package: Entity Component System (ECS)

-

How to reproduce:
1. Open the attached user project “DotsComputerBuffer.zip“
2. Open Scene “SampleScene“ (Assets/Scenes)
3. Enable the “SubScene“ SubScene in the Hierarchy
4. Build And Run (File > Build And Run)

Expected result: The Build has no errors in Log
Actual result: Error in Log: "ArgumentException: Cannot find TypeIndex for type hash 9622449259180854178. Check in the debug file ExportedTypes.log of your project Logs folder (<projectName>/Logs) the corresponding Component type name for the type hash 9622449259180854178."

Reproducible with: 1.0.0-pre.15 (2022.2.2f1, 2023.1.0a24)
Can’t test with: 1.0.0-pre.12, 1.0.0-pre.15 (2020.3.43f1, 2021.3.16f1), 1.0.0-pre.12 (2022.2.2f1, 2023.1.0a24) (Errors in the Console)

Reproduced on: macOS 13.0.1 (Intel)

Notes:
- The type hash is different from the error, this is because the type hash is not stable with a compute buffer element in the component
- Issue is not reproducible in Play Mode

  1. Resolution Note:

    Issue resolved as noted by customer. Issue was sorted out on Discord and the type mismatch is due to ifdefs in the type making it inappropriate for baking

    If anyone has this similar problem, there will not be any fix (hidden ifdef located in Compute/Graphics Buffer breaks editor-build type cache).

    There is a workaround: don't bake the component containing the buffer. Instead add it at start of runtime when all relevant entities are loaded in.
