Re: [Vala] Recursive foreaching

Hello

I've tried something like that (In fact I've began to code a turn based
game... ehm... well ok... I'll explain in the future)

It's my first attempt in vala :
https://sourceforge.net/projects/valatreeobjects/files/

Really perfectible but  it's fun.

I'll try to clean up my code and use vala's best practices later (or if
someone want to have a look ;))

Regards

Raum
