ENIGMA Development Environment

It looks pretty much 100% C++, with only the function names being GML

That is exactly what it is, except many of the functions have different arguments. Since I use Irrlicht for graphics, I plan on implementing them soon. This release was rushed.

C:\Users\Daedalus\Desktop\GDS V0.0.1\GDS V0.0.1>C:\MinGW\bin\g++.exe Internal\Te
mp\tmp\Bin\source.cpp -pipe -DNDEBUG -O -s -o Internal\Temp\tmp\App.exe -mwindow
s -LCompiler\libs -lirrlicht.dll -lcAudio.dll -lgds_engine -lEvt_Handler
Compiler\libs/libEvt_Handler.a(red_evthandler.o):red_evthandler.cpp:(.text+0x409
): undefined reference to `__gxx_personality_sj0'
[MORE ERRORS...]

Those look like linker errors. Try recompiling the engine. Navigate to "Compiler\Evt_Handler" and open the codeblocks project. Compile it. Then navigate to "Compiler\Gds\gds_engine" and open the codeblocks project. Compile it. Open the IDE and try compiling one of the examples. If you still have problems, contact me.

you will miss math definitions like sin(), which are declared using a macro.

Currently, yes they are missed. This will be fixed in the future. This was not a pressing issue.

Like the GUI though.

Thanks. Not the prettiest thing around, but it works (for the most part). If you wish to change any of the icons, navigate to "Internal\Images" and they are all in there. Make sure they stay the same dimensions that they already are.

just that you might help now.

I could consider it

I assume you report errors by regexing compiler output after a #line directive?

No. All I do is open a console, tell MinGW to compile the source code, and output it to a static location. This is done through a windows batch script (similar thing would be done on the Linux port). If there are any errors, MinGW will output them directly to the console. Once the console is closed, the IDE re-opens.
This is the code I'm using to compile, report errors and run the application. The source code is generated before this is called (mashes all the code the user typed in objects etc. into a compilable c++ file)
            std::ofstream ofs("Internal\\compile.bat");
            ofs << compilerpath.c_str() << " ";
            ofs << "Internal\\Temp\\tmp\\Bin\\source.cpp" << " -pipe -DNDEBUG";

            switch(optimization_level){
                case(OP_NONE): break;//Do nothing
                case(OP_LOWEST): ofs << " -O"; break;
                case(OP_BASIC): ofs << " -O1"; break;
                case(OP_NORMAL): ofs << " -O2"; break;
                case(OP_ADVANCED): ofs << " -O3"; break;
                case(OP_SIZE): ofs << " -Os"; break;
            }
            if(op_stripbinary){
                ofs << " -s";
            }

            ofs << " -o Internal\\Temp\\tmp\\App.exe";
            ofs << " -mwindows -LCompiler\\libs -lirrlicht.dll -lcAudio.dll -lgds_engine -lEvt_Handler";
            ofs << "\n\n\n";//End compile output to .bat file
            ofs << "cd Internal\\Temp\\tmp\n";
            ofs << "App.exe\n";
            ofs << "pause";
            ofs.close();
            Show(false);//Hide IDE while compiling
            system("Internal\\compile.bat");//compile+run app

It's interesting how you have an image editor, but that seems to have come at the price of being cross-platform.
If we're lucky, LGM will have one of those before the world ends.

Yes it would be nice for LGM to get one. The IDE will be cross platform, I could make it so in probably a week if I buckled down. I just developed it on windows because I was trying to replicate gamemaker and it was just easier being able to play around with it while making the IDE. It is designed fully in C++ with wxwidgets for the IDE. If I needed something faster (hardware accelerated) I used SFML. Every library I used works with windows, Linux and Mac.

I notice you kept many, but not all of the functions; [....] why not keep the whole library?

The engine is a WIP. I am in the middle of adding more GML functions, I just rushed this version to release. The engine is open source, so anybody can edit, add or optimize it.

if your syntax and everything is so similar

You code in pure C++, there is no parsing of anything. I just attempted to make C++ as GML like as possible to make a shallow learning curve, while still using code that is valid C++.

This is a project that I have been working on for the past nine or so months. It currently only runs on windows, however Linux and Mac(?-does anybody actually develop on a Mac) support are coming in the future. I also plan on IPhone and Android support. To sum it up, it is like ENIGMA - An alternative to gamemaker - with an open source engine, and it is completely free. It uses Irrlicht for the graphics, and I created the IDE to closely mimic gamemakers.

UPDATE (March 17th, 2012):
-Bug fixes (you should no longer get the linker error while compiling).
-Support for sprites, animated images.
-Few other things

UPDATE (March 13th, 2012):
-Now supports shaders (pixel and vertex)
-Bug fixes (Some Major)
-Find Supported resolutions
-A Bunch of Other stuff

Okay thanks. I managed to create a test function that works, and compiles on ENIGMA. I'm going to [attempt] to replicate the d3d functions in OGL. I've done it before in DX, so it shouldn't be that much different.

Another quick question. Searching through the source file, it seems MANY functions are commented out. Is this because they are incompatible at the moment?


Here's how to write Good Code. Enigma seems to follow this (it has been re-written 4 times right?)
http://xkcd.com/844/

Okay I downloaded the newest Enigma (r618) and it said that MinGW was found, but was missing a library. It gave me the option to un-install it, and reinstall from scratch or try overwriting the existing MinGW. I chose to uninstall my older version, then re-download it all through Enigma (to reduce the amount of possible bugs). I started up Enigma and it download a whole bunch of things, however when I went to compile the "CompilerSource" it pops me up the error:

mingw32-g++.exe: CreateProcess: No such file or directory

I know this is not an enigma error, but I've only encountered it after I uninstalled my previous version of MinGW and installed it through Enigma. I can not seem to compile anything, even my older projects that have worked fine before. I checked the compiler paths to make sure that it was pointing to the right directory and it seems to be correct. "C:\MinGW". I was wondering if you could help me out here, on this probably newb error. I am a beginner with C++ BTW.

Thank you very much

Windows 7, 32bit.

How much (size wise, in MB) does Enigma have to download after first running it? Also how big is Enigma (in MB approx). I have really slow internet, and I still havn't got it to work, I was waiting a little then popped back here and saw this. Thanks.

PS: I too am using Win7, 32bit.

Thou here we could change float to int, thus creating an (substantial?) speed increase, because I don't see why width, height or position should be decimal.. Thou you have made all positions and sizes in all functions floats for some reason. I know that GM allows x and y to be a decimal, but I don't get why. You cant have something 1.5 pixels from somewhere. Its a lot better if is 1 or 2 pixels.

GM allows X,Y to be decimals because you can modify the view so that those little differences matter. GM has 3D support, and all 2D functions work in 3D as well so the decimals matter when the view is transformed.



[EDIT]
Not sure if you can do this in OpenGL (I've only used DX) but you can get DX to do this automatically for you. Simply turn texture repeating on and then put a vertex at the 4 corners with texture cords changed.

Something like this? (Never used OGL before, so it needs debugging)

.H file
int draw_sprite_tiled_area(int spr, double X, double Y, int x1, int y1, int x2, int y2);
.CPP file
//int spr, double x, double y, int x1, int y1, int x2, int y2
//Draws a rectangle between [x1,y1] and [x2,y2] with the sprite offset by X and Y (both 0-1)
int draw_sprite_tiled_area(int spr, double X, double Y, int x1, int y1, int x2, int y2){
  enigma::sprite *spr2d = enigma::spritestructarray[spr];
  //Non existant sprite
  if (!spr2d) return -1;
  //Some error? No idea, but it is used in the above example too.
  if (enigma::cur_bou_tha_noo_sho_eve_cha_eve != spr2d->texturearray[subimg % spr2d->subcount]){
    glBindTexture(GL_TEXTURE_2D,spr2d->texturearray[subimg % spr2d->subcount]);
    enigma::cur_bou_tha_noo_sho_eve_cha_eve = spr2d->texturearray[subimg % spr2d->subcount];
  }
  const float tbx=spr2d->texbordx;
  const float tby=spr2d->texbordy;
  const float sw = spr2d->width;
  const float sh = spr2d->height;
  //Texture repeat ON
  glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_WRAP_S,GL_REPEAT);
  glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_WRAP_T,GL_REPEAT);
  glPushAttrib(GL_CURRENT_BIT);
  glColor4f(1,1,1,1);
  //Draw the quad
  glBegin(GL_QUADS);
       glTexCoord2f(x1/sw*tbx+X,y1/sh*tby+Y);
       glVertex2f(x1,y1);
       glTexCoord2f(x2/sw*tbx+X,y1/sh*tby+Y);
       glVertex2f(x2,y1);
       glTexCoord2f(x2/sw*tbx+X,y2/sh*tby+Y);
       glVertex2f(x1,y2);
       glTexCoord2f(x1/sw*tbx+X,y2/sh*tby+Y);
       glVertex2f(x2,y2);
  //End drawing
  glEnd();
  glPopAttrib();
  return 0;
}
