Uhh...Where is the On-Post C++ tutorial? I always came here for a reference when setting up a Dll...

Is it possible to create .dll's that works with Game Maker in C#?

[TheMagicNumber]

Yes, but there will be extra work. It's not really nice: You can fiddle with the DLL (or have a program do it for you), or use a wrapper (like GM .NET Layer) to interface it.

And why exactly my tool wasn't mentioned?
[sarcasm]Oh right, because I made it.[/sarcasm]

Dose anyone know how to find all the functions for Pascal (make a message, play a sound...) I know the syntax, but dose pascal have a big help thing like GM that tells you all it can do ?

Is it possible C# DLL's to be defined by Game Maker?

You'd need the WinAPI documents, they are the functions you're looking for. As long as you know how to use them, you should be fine.

Is it possible C# DLL's to be defined by Game Maker?

With a wrapper, yes.

i made simple dll in pascal i put in same directory as game and i use

global.define_PAInit = external_define('PetAi.DLL','PAInit',dll_stdcall,ty_real,0);

butit says error defining external function..
thats function:

Function PAInit():real;  stdcall; export;

so what is the problem

@_165591: Just a hunch (and late reply), but try this instead:

global.define_PAInit = external_define('PetAi.DLL', 'PAInit@0'
, dll_stdcall, ty_real, 0);

I think I PM'd tangibleLime about this a while ago, but this tutorial doesn't work:
1. Pages are missing
2. It talks only about 16-bit ASM, whereas Game Maker is 32-bit.
3. It doesn't mention anything about programming for Windows (vastly different to, for example, real mode programming)
4. It (of course) doesn't talk about DLLs in any way.

4. It (of course) doesn't talk about DLLs in any way.

It's strange, isn't it. This topic used to actually tell you about making DLLs in the language, now it tells you about the language.

For those who get "Error define external function" in GM
Add the DLL init function:
C++

bool APIENTRY DllMain(HANDLE hModule, DWORD dwReason, LPVOID lpReserved)
{
   return TRUE;
}

Has anyone used get_function_address() yet? I get that it gives you a function pointer, but I have no idea how to actually call into the runner from a DLL. Any tips? A usage example in C++ would be great.

I got a few nasty surprises by calling this function, by the way. Putting it in a debug watch field or as a constant caused my OS to BSOD. I have no idea how that could happen just by reading a number out of a table, but there it is.

Edit: Then again, maybe it was caused by the room being empty. GM 8.1 has some weird bugs.

Any news on this. Stumbled across this function and people here around say that it is a big step, yet there's none explaining how to use that at all...
A quick hint of it's usage in C# would be also nice...

Very much thanks in advance!

OK so i tried to make a simple dll to play a sound
here is my code:

#include "SoundDLL.h"
#include <windows.h>
#include <Mmsystem.h>



export bool snd_play(const char* file_path,bool loop)
{
       bool result;
       if (loop==true)
       {
		result=PlaySound(file_path,NULL,SND_FILENAME|SND_LOOP|SND_ASYNC);
       }
       else
       {
       result=PlaySound(file_path,NULL,SND_FILENAME|SND_ASYNC);
       }
       return result;
}

but when i try to compile i get this error

[Linker error] undefined reference to `PlaySoundA@12' 
  [Linker error] undefined reference to `PlaySoundA@12' 
  ld returned 1 exit status 
 C:\Dev-Cpp\Projects\SoundDLL\Makefile.win [Build Error]  [SoundDLL.dll] Error 1

Could some1 please help me :(/>

Your problem looks like it is with a function in the SoundDLL.h file you included. I'm not exactly great with C++, but I think you're gonna need to post the code from SoundDLL.h
<edit>
Or...it might be the fact that you've got #include "SoundDLL.h"
Shouldn't it be #include <SoundDLL.h> ?

Ha ha, i too was victim of that somedays , but i have successfully found a solution.
You need to add library called libwinmm.a in your project.
