We may not know much about Java coding, but at least we're trying to get a result.
Sadly, will
is not all that counts. Even if you have all the tools, you cannot build a fancy skyscraper if you don't know how to use those tools .. and on top, you don't even know how skyscrapers must be constructed in order to not collapse.
It is as Storebror said up there:
Forget about this project.
It's beyond your friend's knowledge by far and no one here will pick up that baton for you in due time.
We don't say that to make fun of you. It is a friendly advise.
There, you even said it yourself:
[...] this kind of things is too complex for him
Put your energy into something that will not result in a big pile of wasted hours and frustration.
Are you aware of the dimensions at all? Let's get this straight once and for all:
The fact that
no one picked up this task yet is not because we Modders wouldn't care for it .. but simply because Zuti's code is
massive and on top deeply woven into and dependant onto the base classes of the game, which btw got changed
a lot themselves inbetween v4.10 and v4.12 ...
And even if you knew Java and had the time to pick up this enormous task, then there's still one barrier left: IL-2's net replication. If not done correctly, your ported Mod will be one big bug. Period.
