But why not use RCBasic to write the game? RCBasic is more versatile.

Awesome aurel, and looks complicated lol, you must really like tinkering in the lower level stuff eh? |

I use C because i found it on gemedev forum and just modify it ,it is pure GDI win32api so i can easily translate it to o2
where code will be much smaller using my own include file,but with same speed of execution.

So, translate it and then post it here. Together with a link to the place you've found the original C code. And I agree - creating this kind of retro game in C doesn't really make sense when you could use RCBasic or NaaLaa. I was playing with C and Raylib recently (mainly because I wanted to gain some experience with C) and can say that it's much easier to use Raylib with other languages (especially Go and Ruby). Is it possible to call C libraries from Oxygen Basic? It would be something If you could create Raylib bindings for O2. Here is the list of already existing bindings - github.com/raysan5/raylib/blob/master/BINDINGS.md . At the moment, the only BASIC there is FreeBASIC. I was thinking about trying to make bindings for NewLisp, but it looks like NewLisp kinda died last year. |

Hey tomek
Yes of course that can,and not only that ,it can use dirctly windows.h include from C compiler.
o2 already have bindings to openGL,SDL..
For raylib i think that not have ,by the way i doub't that anyone there( on Oygen basic forum )have interest.
I don't have interest in raylib because i prefer GDI,GDI+...
I even don't have any interest in SDL,openGL and that i am author of o2 i would go with DirectX on windows
simply because have best performance in any games on windows.

WOW i just look into the list ..it is really impresive even my old friend Fayed add binding to his Ring language..nice  |

At the moment, the only BASIC there is FreeBASIC. Blitzmax syntaxbomb.com/index.php/topic,7600.0.html (Add www.) Blitzmax may be better than FreeBASIC in game development. The community looks more experienced in game making. If a developer encounters a problem, it may be easier to obtain a solution. syntaxbomb.com/index.php/board,19.0.html (Add www.) |

i found something more interesting for me win32GDI graphic engine Is win32GDI equal to DirectX? |

Post by aurel on Apr 12, 2020 7:29:17 GMT -6
No ken
is not same ,GDI and GDI+ is a set of drawing functions built in Windows OS and DirectX is hardware based set of 2D/3D functions
which comes with your graphic card driver.

Sorry, I missed BlitzMax. That list is getting bigger and bigger every time I visit. BTW The new Luajit bindings for Raylib 3.0 are fantastic. Just two executable files - one is an interpreter, the other can glue your script to the interpreter and produce a standalone executable. No compiling. No dependencies. Just one file that is created instantly and ready for distribution in less than a second. Plus, of course, for your programs you've got the speed of Luajit and the simplicity of Lua. Grab it from github.com/TSnake41/raylib-lua/releases/tag/v3.0a . Binaries for Windows and Linux are ready to download, as well as the source code. |

sorry tomek but lua is just another glue language which heavily depend on ext libs and i really
doubt that anyone here is interested for that.

Post by Tomaaz on Apr 13, 2020 8:17:30 GMT -6
What I'm trying to explain you is that this is not a library for Lua. This is a single executable that already contains Luajit and Raylib glued together. THERE ARE NO EXTERNAL DEPENDENCIES. You don't need any headers or .dll files. Also, you can glue your script with that executable. What you'll get is another single executable that will run on any Windows machine and won't need any dependencies. You don't have to provide Raylib libraries with your program. There are already included in the .exe file you've created gluing your script with raylua.
For me the most important thing about it is that it works the same way on Linux. All dependencies are included in a single executable file. To run this file other Linux members don't have to install anything. Remember EGSL? It was possible to glue your script with the interpreter and make an executable, but to run this executable on another machine you had to have specific SDL libraries installed. I believe (sorry, if I'm wrong) RCBasic works the same way.
