how do i work with multiple sprites in one project and combine their respective scripts?

Sprites all have separate scripts. You can duplicate sprites which will copy all the costumes and scripts from one sprite to another. You can also clone sprites in version 2 where you have an extra event “when I start as a clone”. Perhaps you can provide some more information about what you're trying to achieve?

You can also drag&drop scripts into the backpack to reuse the same script in other sprites

And don't forget that you can let one sprite send a message (make sure it's a message that is for all sprites) that the other sprites can react to

Here is a great tutorial on working with multiple sprites:

Best to start your own topic.

Make sure both sprites are told to show and one isn't hiding behind the other.

NB I'm assuming these are separate sprites and not just two costumes of the same sprite.

Same with me. I asked my friend and she said add more sprites but it will not work :-(

It will not work for me
