My cBlockArea seems to be working, I've just used it to implement proper leaves decay. Yay

STR_Warrior, you patched Trees.h to exclude leaves from the list of blocks that don't block tree growth, any specific reason for that? They were there specifically so that there are enough trees in forests.
otherwise the vines of the trees would go trough the leaves of other trees and bushes
Ah, that should be easy enough to fix otherwise. I'll try.
Done in Rev 646. I also refactored your code, there was no actual need for two separate functions, one could simply handle all the heights by using a wider random interval.
Also I started a nightbuild at my home server, just in case

ok so i googled for nothing xD probably becouse i am a verry verry verry (etc) beginner in c++

Hey, you did great, you made (kinda) jungle trees

can you also make the vines decay when there is no block attached to it??
EDIT: also jungle leaves drop normal saplings not jungle saplings
I'd add that to the list of Easy Enough tasks. There's already a similar code that breaks sugarcane and cacti, so it should be a half-copypasta
The drops are handled in cBlockToPickup::ToPickup(), I think it's something you can easily fix.
