How do I save a lot of objects?

Hello.

The question may be very common, but I need help in my particular case.

In my game there is a large location which has a lot of randomly created objects like trees, stones, and so on

How can I store their positions and states as efficiently as possible so that I can load them later?

Thanks!

Put this in a condition once all object generated-> System: Save game to slot "you_name_it"

If you want to exclude object from save list just add behavior NoSave. Load object would be straight by using Load game command.

For more specific need better to create a level editor.

Why do I need a level editor for a randomly generated world?

Probably just overwrite the saved game would be an easy option then.

You can also use an array to store the x/y coordinates (and other data), then draw/destroy the objects at any time.

Here's a quick example (though it's not very elegant, I'm sure there's a nicer way to do this!)

But what If I wan't to destroy some of trees?

Any changes on screen should overwrite previous save state. Give it a go and observe the result.
