当精灵在视口之外时如何删除它们，但如果我返回它们的位置以保存 memory，然后再次添加它们

Question

I'm creating an open-world RPG like Neverwinter nights. But I'm worried about memory and am afraid if I just populate a huge world with physics-based sprite nodes, I won't have any memory for anything else.

To combat this, I want to remove the sprites when they go far outside of the viewport and then re-add those sprites when I get close to their location.

How could I accomplish this?

To any and all who take time to help me with this, thank you!

Answer 1

You can store all data on a database like CoreData with exact parameters you need like states and positions whatever do you need.

Then you can create a method to get all objects on a specific position with radius and use this method when the player moves or when you need to check things like a quest on another site, take those objects and compare with current objects, place again on the correct site the new ones and remove the old ones (they are not on radius probably or disappears for another reason)

This is a complex approach but it could work.
