It has nothing to do with the parameters, its the 'engine_open' function itself.

This is a 'PInvokeStackImbalance', a much more serious error which will corrupt the statck leading to all kinds of problems.

The problem is due to that the managed signature/method name does not match the unmanaged function in acknex.dll, upsetting the stack.

The weird thing is, is that this is handled by the wrapper with the P/Invoke declaration / mashalling stuff. I've never experiences this exception before whilst using the wrapper and so I'm not sure of the cause.

What version is the acknex.dll you are using?

My acknex.dll is version 7.8.4.2 (8,0,0,1) .
I'm using the latest A7 release (7.86 pro).

[edit] also, when trying to start my compiled exe, i get these errors:


I never included default.c, nor do i know what MZ is

hmm this is really strange, why does it even use default.fx?

@BoH_Havoc
Sorry, I was/am kind of busy lately, I unfortunately didn't look at this thread for a while !

I also experienced the error you mentioned under VS 2010, i uploaded a fix for VS 2010 on the acknexwrapper.matthias-auer.net homepage !

I also hope to upload a beta version of the new wrapper (only for 7.8x atm) in the next days (hopefully not weeks) - if i find enough time !

The new wrapper won't use unsafe code anymore, the usage of strings will be improved and won't use a var object, only normal doubles and ints, and the engine objects like ENTITY will have class methods which are the corresponding functions in lite-c like ent_create (although I'm not quite sure whether this will prove to be handy in practice - as it's not always intuitive where to find a function that one searches)..

Hi, when I use "yield return ScheduleMethod.PROC_EARLY;" the engine (A7) crashes. Do I have to consider something when using PROC_... or is this a bug?

Thanks in advance!

hmmm this should work afaik, did you add “A7_WRAPPER” to Project Properties > Build > Conditional compilation symbols ?

Yes I did add "A7_WRAPPER" before. I readded it but still it won't work.
If I comment the PROC_... lines everything is working fine.
I tried the same code snippet in A7 without the wrapper - there it works.
btw: I use Visual C# Express 2010

Debugging: http://img266.imageshack.us/img266/4423/62305807i.jpg

I am using A8, but find if i do not add
yield return 1;
somewhere before
yield return ScheduleMethod.PROC_LATE;
it also crashes.

I have this in my camera method and it stops the jagged panning,which returns when i remove PROC_LATE, so it seems to work.

I've installed A7.866 but can't reproduce the error !
could you create a small example and post the code here or send me the small example project ?

EDIT :
thanks pararealist now i can reproduce it too !

btw, I'll post the link to the new version in the "C# wrapper 2.0 - RELEASE" thread - the thread for the new wrapper (not the old one from some years ago !"

Thank you very much, it works now.
