Hi, I just want to post my changed chainsaw.lua file here.
You can cut down the trees from paragenV7 mod now with the chainsaw. This mod adds a acacia tree, a pine tree, a cactus and it changes default trees and jungletrees.
The pine tree was a bit tricky because it has snow on it, but with some changes now the chainsaw should remove the snow, too.
Although I added code to give you only some of the leaves and not all.
And I added acorns and cones from moretrees mod to the removeable nodes, so the sky is not cluttered with them after cutting down a oak for example.
You can put it in technic pack instead of old chainsaw.lua if you like it.
Please copy this code to /technic/technic/tools/chainsaw.lua:
