Find out what could cause C2440 when building to IL2CPP

[Hertzole]

Hello

I’m trying to build my game using IL2CPP but I get a C2440: 'type cast': cannot convert from 'Type_XXX *' to 'Type_YYY' exception. Now, this might just be a Unity thing but most likely not. I’m doing code weaving in this project and it will be incredibly difficult to track down exactly where this issue occurs. Is there some way I could track this down better than just removing parts of my very interconnected weaving and hope for the best?

EDIT: I should add that I’m using Unity 2020.3.10 and the very undocumented ILPostProcessor + Mono.Cecil for my weaving.

Hello @Hertzole ,
I’m getting the same error message during build on Unity 2022.3.10f. Did you find a solution to this issue?

Many thanks
