The spaceship is not shooting.

I want to make an enemy spaceship move from right to left and shoot projectiles at the same time and the projectile refuses to come out of the cannons. Can you tell me what the problem is? Here's my code:

You are spawning projectiles only when the spaceship is created. You should do this on Timer event, or every X seconds etc.

If this doesn't help, run the game in Debug Mode and check laser and missile sprites in the list of objects.

Also, I recommend using layer names rather than numbers in events. This way when you add a new layer to the layout, you won't need to update existing layer numbers in all events.
