I've made a wonderful optimization to Airscape by dividing up all the levels into a grid and destroying certain static objects which are too far away from the player, and using 'recreate initial objects' To bring them back when the player gets nearby again. All of these static objects are part of a family and so can be easily regenerated with the aforementioned action.
It works fantastically, however I've run into a fairly substantial issue and I was wondering if anyone could help out.
Airscape has a robust 'terrain motion' system where almost all the game objects can optionally be pinned to nodes that will move them in certain ways. Most of the static terrain instances that are subject to the optimization aren't pinned to nodes like this, but in most levels a few are. When using the create/destroy grid optimization, these pinned objects are destroyed/recreated - and when they are recreated, they are totally misaligned with their node and unpinned, since the initial state is reset.
Putting the nodes themselves in the family isn't an option, because they need to be operational even when the player is far away. Doing other sorts of fancy tricks won't work either - what happens when destroyed terrain is brought closer to the player by a node?
All I need is a way to exclude certain instances from the destroy/recreate process. Excluding them from being destroyed is easy, because I have full control over my method of destroying objects occupying a certain region. Excluding them from being recreated, however, is proving impossible as the 'recreate initial objects' action doesn't leave its loop exposed to the event sheet - it simply recreates all instances - and if those instances haven't been destroyed, it just creates another copy on top of them! If the action was instead 'recreate instance' I could do something with that - but as it stands, it does appear like there's no way to exclude certain instances from this action.
It's possible that I could create my own recreation function entirely, by storing valid objects in JSON format at start of layout (along with their coordinates) and recreating them as necessary, but this seems messy and expensive - I'd have to use the Nickname plugin to recreate objects by object type. Presumably for the 'recreate initial objects' action C2 does this internally, or something similar, but in a more efficient way.
Does anyone have a method that I could have missed? And does anyone thing that this is a feature worth looking at adding?
