Title: PlayGate Framework

Species: C++ & GML Framework

Description:

PlayGate it's:
The system by which you can connect GML with C++, it's will allow for greater (and even the total) to safeguard and improve the efficiency of games operation. In this version, there is no encryption algorithm, so it is possible only partial decompilation of generated module (GML code cut into pieces, but rather unable to do so throughout the GML game only on pieces of code - the rest of a valid code, remains in the module as the active variables ;p). The license, informations and example how to use, are placed in the file "PlayGateFramework.cpp". Framework was written in Dev-C++ IDE 4.9.9.2 and I recommend it to use. It may be useful, although basic knowledge of C++.
How can we use PlayGate?
Your best way, may be to place the pursuit of individual GML code, which will behave as normal GM application, but you can also get information from GM, to collect them and then use with other C++ components (various sophisticated calculations, which will perform faster than GM would have to do this). PlayGate uses GMThreads (author: Snake) so that we can produce code GML only when you want and wait for the result and adequately perform the next command.

I don't know what it is.

[PsichiX]

This is the c++ dll framework and GM interface. It is intended to protect game, against decompilation.

[biggoron]

How does it work? Something awful happened to the formatting in PlayGate.h and GMThreads.h

[PsichiX]

Open "PlayGate.dev" in DevC++ and see an example of how to use GML code. You can edit the relevant sections, and then build the DLL and running GM game written in C++, additionally protected.

I still don't really understand what this is supposed to do but the code could use a lot of improvement.

It seems you've written a C program with sprinklings of C++, you're not really taking advantage of C++ features and you're clinging to deprecated C functions, like strtod where it would be better to use something like Boost's lexical_cast, and using char strings where it would be better to use STL strings. Also, the documentation in the comment at the top of PlayGateFramework doesn't match the functions.

PlayGate::ExecuteResult is a void (int, string) in the comment, but void (int, int, string) in the code.

[johnie102]

By not looking at the code (I wouldn't understand it anyway) I think that this is supposed to execute GML code from inside a C++ source, so that that source code can't be decompiled.

[PsichiX]

For now, only a part of GML code can be decompile.
The next version will contain the encryption and decription algorithm.

[fire_soul453]

So, this lets us hide some gml code in the dll making it very hard to get to? Sounds useful.

[PsichiX]

PlayGate also makes the game written in c++ is faster than the game written in GM

Have you tested this? How would you make GML written in C++? It all needs to be parsed, right?

[HaRRiKiRi]

Its actually slower, as it uses execute_string (as far as I know). Also, it lags if your PC is stressed, but that could be changed in priority argument in gm threads. With lags I mean, that in your example a lot of times the buttons didn't work because my cpu used.

[PsichiX]

Strange .. but it does not use execute_string()

[fire_soul453]

I try to compile and get
[Build Error] exe: *** No rule to make target `PlayGate_private.rc', needed by `PlayGate_private.res'. Stop.

Have no idea why.

All I did was add

PlayGate.Execute(3,0,"PlayGateReturnDouble(show_message('hello world');)");

(just seeing if I could get it to work)


Anyway a tutorial would be nice

Ok I got it to work.
First of all I had spaces in the directory (you cant have those)
It still didn't work for me so I tried compiling with wxDev-C++ 6.10.2.

So I finally got it to work. I go the message Hello world to pop up (to bad GMThreads has a bug that prevents you from being able to press ok, but then I dont have to use them).

So I would like to say thanks!
This is simply amazing.
I plan on using this.

[grumpymonkey]

so..this turns GML into C++ coding so it cant be decompiled? or does it turn ur game into a c++ game? OR is it something that makes sense? (unlike what i said )

GMThreads uses execute_string. It uses a little hack to get to GM functions. The only function needed is execute_string.

No but you can hide some gml in it. It will use gmthreads to run your gml. You can also use c++.
Like you could get some variables from game maker and run the equations though c++ (Faster, but it takes away some speed because it has to be put back in game maker). If your gm program had to do some advanced math (or just a lot of math). It would be faster to do it in c++.

It is slower to run gml in this because it has to get it from the dll and then put it in game maker, but you can hide some of your gml in this. (like maybe your file encryption's for resource files or something)
