The scripts were streamlined using more or less the following conventions:
- space after a comma in lists of arguments
- space around weak operators (+, -), no space around strong operators (*, /)
- space after a comment start (#)
- removed trailing spaces or tabs, apart from those that delimit the function indentation level (those could be removed too but since they are added automatically by the editor when typing code, keeping them for now)
- function blocks separate by two newlines
The scene files were resaved with the (current) 2.0 format, and some scenes that were in XML format were converted to SCN, to be consistent across all demos.
2.NodePath replace to instance_ID(can control object doe's not in scene tree)
3.Change interpolate types from Node to Object, can control more types(etc script class object)
4.Add pending_update counter, avoid insert/remove interpolates-list while traversal it
