Only applying movement change only when overlapping object

Hello, I'm working on a top-down shooter game, and I created an enemy which shoots at the player when it is overlapping an invisible square that follows the player, and I've been trying to make it so that when it's overlapping the square, it stops moving, but when the player moves away taking the square with it, the enemy starts moving again to get closer to the player and shoot it.

The problem I have is that, yes, the enemy follows the player and stops moving and starts shooting when it overlaps the square, but when I move away, the enemy does not try to move, so the only way to get shot is getting close to it.

If you know how to fix this, please tell me.

Thank you!

Link the enemies movement to the players movement - so that if the player is moving, the enemy is also moving.

something like

if player speed > 10;
set enemey speed = 10

No, I want the enemies to always follow the player, but stay still and shoot ONLY when they are overlapping or touching the invisible object that follows the player.

Now that I think about it, I think I might interchange this, instead of an invisiblke object following the player, I might make the object follow the enemies, so that when the player touches or overlaps the object, the enemy will stay still and shoot. I'll give it a try.

What you're explaining there is somewhat impossible ...

If an object is following the enemies and the enemies are following the player then unless they do a perfect loop around - they'll never meet.

Then I explained it badly.

It's following as in always in the same position as the player or the enemy, it depends on who I put it on.

It would be better if you create a small .mfa with what you're trying to achieve and just point out where your event is failing - that's easier to fix than to try and recreate what you're doing from scratch.

However, I've attached an example that might give you an idea.

I've tied the trigger object and the enemy to the player's direction and speed. They're not moving independently, but being placed i.t.o. the player's position.
However, because the enemy has less deceleration than the player and trigger object at any point if the player stops, then the enemy will run into the trigger object and shoot. But if the player never stops, the enemy will never overlap the trigger object.

always pin the square to the player. then do this:

always
--> set enemy flag follow ON

enemy is overlapping square
--> set enemy flag follow OFF

enemy flag follow is ON
--> chase player
