Bullet problem!!

I ran upon a problem that is either a glitch or something I did wrong. I created the bullet and placed it on the layer. The I coded so the bullet will spawn from the hero. But when I start the game the bullet flies across the screen but I can still shoot bullets from the hero. So i tried deleting the "free" bullet but then the bullets that spawn from the hero becomes HUGE and wont even move! Anyone else have this problem??

Add an event: On Start of Layout - Destroy bullet

Or better yet, add the destroy outside layout behavior to the bullet, and place the first one in the margin outside the layout in your layout editor.

I recommend following the Beginners Guide to Construct
