Gamestudio 8.47 - 03/07/16 14:51

A new version is available for a public beta test:

http://server.conitec.net/down/gstudio_8470.exe

This version is supposed to fix the two random crash bugs that were recently reported. Please check carefully if everything works.

I can confirm that the reported engine crash doesn't occur with this new version.

I'll do some further tests this evening.

Seems to fix the Wichtelwald problem as well. I'll quote the original post in the corresponding thread.

Great, thanks!

So far everything is working fine in multiple projects. Yesterday my main project started to crash ("acknex has stopped working") when using "Test Run" instead of "Run Current Script", I assume because of different command line options. This crash is now gone, too.

Re: Gamestudio 8.47 - 03/07/16 20:13

Have there been any changes within the compiler?

With this new version I get a "Wrong type CONV:POINTER::DOUBLE" when trying to access one of my external dlls.

I try to break this issue down to a small test script.

Here's a little test script:

plugin_test.rar

This one works fine with 8.46 but gives me a syntax error with 8.47.

Your header misses all type information completely. Frankly I'm surprised it ever compiled in the first place.

Re: Gamestudio 8.47 - 03/07/16 21:29

I really don't like that thing of not writing type information but AFAIK all parameters without type are expected to be/ treated as var, as well as the "function" keyword itself (or is it void?). So that should be fine I guess.

As far as I remember you don't need type declarations in dll function prototypes. At least there are none in the basic dll plugin example in the manual.

Re: Gamestudio 8.47 - 03/07/16 21:46

I think that's only because the DLL functions in the example use and return var values, something with that _VAR(...) macro or whatever it was.

function is an alias for var, so the return type is there. Anyway, not declaring a type is something that was legal in K&R C and up to C89, looked something like this:

Code:
void foo(x)
    int bar;
{}


It's no longer valid since C99, for very obvious and good reasons. You can ommit the name though, and write something like "void foo(int, char*)". BSD is infamous for having type signatures like that. Imho everyone who is into the UNIX philosophy of using the least amount of characters to write a function declaration should be stoned, but nobody is asking me who should be stoned anymore these days (but seriously, who is expected to understand "void strncat(char*,const char*, size_t)" without looking it up?!)

So yeah, no, not legal. However, since we are at the topic of C quirkiness, anyone want to take a guess what the difference between these two is?

Code:
void foo();
void bar(void);

The first one will accept ANY argument, you can call it with as many arbitrary arguments you want. The second one doesn't accept any. C++ did away with that insanity, also for good and obvious reasons.

Tried one of my scripts which is using mtlFX.c and got this.

I'm using Lite-C Free.

I use this plugin with this kind of function prototypes since 2008 without any problem ... until now. So there must have been a change with this version or accessing external plugins via dll isn't possible with an open beta version at all?

Re: Gamestudio 8.47 - 03/08/16 09:17

Thanks for update!
Btw, i got same error like HellThunder.

Re: Gamestudio 8.47 - 03/08/16 16:57

Yes, the error is caused by functions with no parameter types. This is not intended, so I'll upload a new version tomorrow with the old compiler behavior.

I was mostly trying to say why the code shouldn't have compiled in the first place. If I may ask, why don't you provide type information? The type will default to int, which may or may not be the size of a pointer (most likely it will be on a 32 bit system), but the type int is only guaranteed to be at least 2 bytes. Same with using function, var is not really a type meant for holding pointers. Just because everyone does it, doesn't meant everyone should!

I guess the reason was the example in the manual:

Quote:


Using the DLL in C-Script and lite-C

...

In lite-C it's just a normal prototype (and you can use other variable types than var), in C-Script we need a special dllfunction declaration:

dllfunction ldexpc(x,n); // declaration of a DLL function in C-Script
function ldexpc(x,n); // declaration of a DLL function in lite-C



I also assumed that the default type is var not int.

Re: Gamestudio 8.47 - 03/09/16 13:11

This is the new version with no error message for missing argument types:

Re: Gamestudio 8.47 - 03/09/16 13:56

Everything's running fine now ... engine crash is gone and missing argument types are no problem anymore.

I'll do some further tests this evening.

Re: Gamestudio 8.47 - 03/12/16 10:41

Was there something changed with MED (highly unlikely, I know)?
Since the patch MED crashes every now and then on some bone operations, like trying to move a bone. The last MED crash before that was many years ago.

Re: Gamestudio 8.47 - 03/14/16 07:37

No, it's the same MED as before.

Re: Gamestudio 8.47 - 03/21/16 21:57

Have there been any changes within the compiler?

When I compile a larger level, the Ram is not enough, My ram is 32 GB.
That was not there before.
When compiling with activated terrain lihgtning.

Re: Gamestudio 8.47 - 03/22/16 08:03

No change of the compiler.

Re: Gamestudio 8.47 - 04/07/16 13:02

Hm sadly I'm still getting the "bad file format" error, with WMBs though.
Happened 3 times so far over ~10 days on the first level_load call (for the menu.wmb which hasn't changed in quite some time).

EDIT: I'm not quite sure how long I've been using the "-ns" command line option. I'm gonna remove that again and see if the error still appears. Happens without "-ns" too.

EDIT 2/3: When I load a (NULL) level before the background loop function which uses ent_createlayer() to create a SKY entity, the sky entity won't show up in a view, even though the client_id property remains NULL. If I'm not mistaken that should be a bug.

EDIT 4: Now I barely get my game to start anymore. It's either "acknex has stopped working", "bad file format: menu.wmb" or a new one, a "script crash" during level_load(NULL).
