Can you provide the IL code for the original method? Not necessarily the whole but mainly like +/- 10 lines around the calling for GetNodeBuilding to compare the IL code that Harmony spits out with the original IL code. Almost all problem can be examined by comparing the original IL code with the final Harmony result that is in the debug log.
Because currently, Harmony does not support TRY/CATCH on the IL level. And even if the decompiled code does not have a try/catch statement, the IL code can actually have it and right now, Harmony cannot handle the meta data of try/catch ranges and thus the corresponding IL codes will not work as expected. As a side result, a finally handler is not executed.

Hi @pardeike
Any luck with this?
Thanks,

I only had a quick look but could not spot the problem right away. The thing is that this error is at a place where Harmony does not interface with the IL code much. It just copies it from the original. The only thing that might be unusual here is that it seems to be a ref this.
I have to look more into this. Meanwhile, would you be able to create a minimal test case to reproduce this? The method here is a bit too big to handle.
I am actively working on the next release that fixes a few things so the timing is right.
Thanks
from harmony.

I have no idea why the IL code at 0007 is illegal. It is the call to your prefix method. That method is static and takes two parameters: NetNode __instance and ushort nodeID and both are loaded onto the stack with the IL commands before: L_0000: ldarg.0 and L_0001: ldarg 1. That makes sense if the original method is an instance method of NetNode. Because the 0th argument is the instance (NetNode) and the 1st argument will be the argument to the method, in this case the nodeID.
Could it be that the nodeID of the original is not the same type as in your patch? I can see of the debug log that Harmony says uint16 but you are using a ushort.

On a second thought, I think it has to do with the type of NetNode. Can you post the definition?

Humm, I just created a new console app and using the skylines dll (and your sample without the struct) it works fine.
There is either something to do with my project settings or how skylines calls the mod dll I guess?

I have tried several iterations and they all work in the console app and not from the game...
Eventually I tried something simple and this didn't work in game but did in the app:
`
public class Node
{
public static void Hook()
{
FileLog.logPath = "E:\error.txt";
NetNode2 node2 = new NetNode2();
node2.CalculateNode( 1234 );
var harmony = HarmonyInstance.Create( "test" );
harmony.PatchAll( typeof( Node ).Assembly );
node2.CalculateNode( 5678 );
}
}
public struct NetNode2
{
public void CalculateNode( ushort nodeID )
{
FileLog.Log( "CalculateNode " + nodeID );
}
}
[HarmonyPatch( typeof( NetNode2 ) )]
[HarmonyPatch( "CalculateNode" )]
static class Patch2
{
[HarmonyPrefix]
public static void CalculateNode_Prefix( NetNode2 __instance, ushort nodeID )
{
FileLog.Log( "CalculateNode Prefix " + nodeID );
}
}
`
Same error.
The project looks identical apart from one being a DLL and one being a EXE.
In morning I will create a new project and see if I can get that working, I can only assume its something I am doing (using a ThreadingExtension and hooking on OnCreated).
Thanks for the help, will get back to you tomorrow.

Unfortunately, I don't have Cities Skylines.
Can you try with simpler versions of the Prefix? Like this:
public static void CalculateNode_Prefix( ushort nodeID );
// or
public static void CalculateNode_Prefix( );I just cannot see why it fails ont the CALL at loc 0007. Maybe I have to add Boxing but I never had to do this so far.

Looks like its because NetNode2 is a struct. It does not work in game but does in the console app.
As you can see below the first 3 tests succeed.
If you need a copy of the game to test with I can get you one if that helps?
