How do I make my object shoot continuously?

Hey guys!

As you expect, I am new here. So here is my question:

In top tutorials about making scroll shoters everyone makes shoting like one tap=one bullet. I tried myself but still I can't do like this: if spacebar(for example) is pressed, my object shots every 0.2 seconds.

Thank you in advance!

Try this capx.

A0Nasser, thank you so much! Yah, it works great :3
