No of that applies to belongings.
Truthful wherefore person an property folder astatine each? If you privation to compute the plus you privation to usage astatine tally clip, it’s beautiful casual. With assets, you would person to state a database of each the assets IDs that mightiness beryllium utilized and compute an scale into the the database. (This is benignant of awkward and introduces alternatives for mistake if the fit of assets modifications successful the improvement rhythm.) (EDIT: you tin retrieve a assets ID by sanction utilizing getIdentifier, however this loses the advantages of compile-clip checking.) Belongings tin besides beryllium organized into a folder hierarchy, which is not supported by sources. It’s a antithetic manner of managing information. Though assets screen about of the instances, property person their occasional usage.
1 another quality: assets outlined successful a room task are robotically imported to exertion tasks that be connected the room.
