What is OpenGL using and how do we get to the source code?
Hello. I need some information.

Flash Player wraps codes into a ".swf" file.
So, with which appendix does openGL wrap the source code?
If you have information and ideas, please specify.

Flash file extensions have Decompiler.
Do you have any advice OpenGL file extension Decompiler?

Note: The game is a web browser game.

You can find more specifics of OpenGL on it's website / wiki:
https://www.khronos.org/opengl/wiki/FAQ#What_is_OpenGL.3F

It is a rendering interface, similar to Direct3D, Vulkan, and such.
It is not open-source, so there is no source code to obtain for it.

OpenGL isn't a standard file extension either, so if something is using .opengl as an extension it is custom to some degree, such as being a precompiled shader/texture or similar, for example.

Since you mentioned it's a mobile game, it's more than likely using the OpenGL ES API instead of the main OpenGL library.

Thanks for the detailed answer.
I am in favor of deepening the subject and I need to find a way.
The game, which previously came with Flash Player, now comes with "openGL".
We could do a "swf" review for Flash, but where should we look with "openGL"?
After the game is installed; We can make a few changes with CE,
but there are values that need to be changed before the game is loaded, I wonder how to get there.

Flash Player has expired-dated; Falling to zero now, bad feeling. Smile
An alternative "Decompiler" is required, but we do not have the source file! Smile

OpenGL is a rendering API, it's not a 1 to 1 thing with Flash. If they replaced the rendering engine with OpenGL then they had to rewrite a handful of the game to redo how things are drawn and such.

You would need to find where the game is making use of the OpenGL API calls and such if you are looking to hook onto the rendering of the game. This is generally going to be in the games libs.
