Unity WebGL

Une petite question qui me trotte dans la tête , le WebGL étant du javascript, une appli en webGL a t'elle ses sources visible depuis le code source de la page ?

J'étais tombé sur ça dans la journée. Ça pourrait peut-être être répondre à ta question.

The asm.js-based JavaScript generated by compiling a Unity project to WebGL is not a direct translation of C#/UnityScript to JavaScript. Instead, it goes through this (rather creative) pipeline:

Your C#/UnityScript code gets compiled into .NET bytecode
A tool named IL2CPP converts the .NET bytecode into C++
This C++ then gets compiled by CLang into LLVM bitcode
LLVM applies heavy optimization to this code (just like machine code compilation, which LLVM usually does)
The resulting LLVM code is then converted into asm.js-based JavaScript
In this asm.js-based JavaScript, all of your scripts, Unity's scripts, Mono BCL and C++ standard library classes are mangled into one big blob of bytes that is massaged by crazy low-level JavaScript instructions.

That's about as hard to decompile as any machine code-compiled application. The most likely path of attack would be to try to get back to LLVM bitcode from the asm.js-based JavaScript and then decompile the LLVM bitcode into plain C. But the result would have close to nothing in common with the original C#/UnitScript code (just a bunch of sequentially numbered functions). It may help someone understand your license check or such, but stealing code this way would be harder than just writing it from scratch.

oui mais de la à les exploiter...

bon, parfait, asm.js-based étant aussi lisible qu'un .exe, il n'y a pas plus de risque ^^
