unless array and a couple of other thing, angelscript seem to be the same syntax as cpp, just need to know the background function specific to fonline who was wrapped into script engine.
angelscript work well on *nix and windows, but i think it is used on the server part only (?)
maybe i can help to port client on linux ? client work nice but his slow. also there are some gfx glich, i think i can help for that,
i get some skill at lowlevel code, for me blit pictures, his write some bit into a buffer, not use directx =)
i just purpose my 'talent' if you need it, do as you want.
