Hi,
Unfortantly I have little success with this.
So I have this function in tag.lua:
--- Return the division tree of the tag
function getdivisiontree(t)
local t = t or selected()
local tree
tree = getproperty(t, "division_tree") or {}
if #tree==0 then
tree={}
tree.division="none"
tree.ratio=0.5
setproperty(t, "division_tree", tree)
end
return tree
end
See Idea is, that when no decision tree exists yet, one is created.
But I get an error:
tag.lua:304: table index is nil
