How do I make copies of enemy act independetly?

Hello,

I'm trying to make a metrovania/platform game with several enemies of the same type. The problem is that they all shoot at the same time, and if I have one is looking for the right, all of them shoot in the same direction

Right now I'm comparing the position of the enemy with the player's, and if I don't kill one of the enemies behind me, all others will shot to the wrong side...

I've seen a lot of similar questions but none seemed to answer the question completely. already tried instance variable and for each, but they didn't work

Instance variables and for each do make instances individual.

Share your project, you must be doing something the wrong way.

Construct 2 is all about instance picking. I had the same problem with my side scrolling space shooter. All my basic orange enemies fired at the same time. I had to figure out how to get Construct 2 to pick them individually. It wasn't easy and I finally had to settle for what looked right. I ended up using a choose random on screen loop.

As for the firing the wrong way.. that sound like more of a bullet behavior issue. Make sure the speed is positive value for left-to-right and a negative for right-to-left.
