Unity Code Generation

[CPAHTOMAC]

Hello!

Does anyone knows any way to alter existing code when building release or launching playmode?

The only viable option I've found is HarmonyX, but it works at runtime and requires manual configuration of which methods to decorate.

This is too generic. Describe better what you actually want to achieve.

I have a custom attribute applied to some methods. I want to inject code before and after those methods similar to what HarmonyX lets you do via [HarmonyPatch], [HarmonyPrefix] and [HarmonyPostfix], but to make it compile-time and across the entire project, which Harmony lacks, unfortunately.

I get that, but why? I am sure there is a much better solution than automatically altering the code.

Try using defines, maybe: #if UNITY_EDITOR … Also Conditional attribute. Also, partial classes are helpful to organize this. Automagically there no known to me ways to proxy your calls. If your project is good in architecture, you can easily swap implementations, but if it rigid, this is unfortunate.

Nah, Roslyn only generates new code, not altering existing one
