How do I access one specific bullet or enemy?

Hi,

In my game enemies shoot bullet at the player and vice versa and I want to find and delete specific bullets like one that hit the player but if I do collision check of bullet and wall, it will destroy all bullets, not just the one that hits a wall or an enemy. I want rest of the bullets stay present in the air.

Same problem goes with A.I., I want one enemy that has seen the player to stop moving but I don't know how to do it in the event sheet.

Hope I was clear enough.

Best.

When you use the condition 'bullet on collision with enemy' and the action 'destroy bullet', it picks only the bullet that collided and will destroy that one instance.

True but the same logic is not happening on other cases as well like the AI example I provided.

If I have three instances of one enemy and one of them las Line of Sight of player, how can I stop that particular enemy instead of stopping all three of them?

In the same way if you use 'enemy has LOS of player' and an action for enemy to stop moving then it will pick that enemy.
