Overlapping identical copies of the same object

Hi!

Tell me how to make an overall for identical copies of the same object?

For example, there is a Sprite. There are 10 copies of it on the layer. Two of them crossed - how to get them?

If you mean pick the two that are overlapping there is something called 'Pick nth instance' under System, where 0 and 1 are the two instances overlapping.

Another popular method is to create a family with this sprite, and then you'll be able to use "Sprite overlapping Family" condition. Where you could refer to both instances separately.

Well I hate to post the same thing again but use Pick nth instance

I'm sorry, my English is very bad, and the translator does not always translate well

But I have another question. How can I call Pick with Action?

For example, two copies of the same sprite collide and in the condition you need to select the first copy, and in the action take a variable from the second copy and assign it to the first copy

How can I call Pick using Action?

Add the sprite to a family. Define the variable on the family and remove it from the sprite. Then you can use this code:

Sprite is overlapping Family
.. Family set var to Sprite.var

Sprite On Drop
Sprite is overlapping Family
.. Family set var to Sprite.var

Add the sprite to a family. Define the variable on the family and remove it from the sprite. Then you can use this code:

> Sprite is overlapping Family
.. Family set var to Sprite.var

Depending on your task you might need to pick the correct sprite instance first. For example if you are using Drag And Drop behavior, then the code will be:

> Sprite On Drop
Sprite is overlapping Family
.. Family set var to Sprite.var

Thank you very much!

And how can the values of two copies of the same object be exchanged during an overlay?

It was:

Copy 1 value 22

Copy 2 value 55

After the overlay:

Copy 1 value 55

Copy 2 value 22

This is much more difficult

Family aproach is the solution. Create family first, add Sprite to it. Previous instance variable won't inherited to family class so create family instance variable with different name.

Filter the IID first by picking lowest ID to identified as first copy by using loop 'For each (ordered)' & set expression to Sprite.IID then add 'stop loop' in action.

This will pick first copy or earliest created Sprite instance.
