How to activate something only when in frame?

[FlinkGigitty]

I asked about this in chat too, and got a suggestion - but it was too hard to fix then, so I took a break. And now I wanna try again

My problem is that the enemies in my world are completly ignoring every kind of event Im making to stop them from move before they enter my frame window. I have used "Enemy is in play area", and it did not work. Ive tested a few other things too, but I think the thing Im looking for is an event to add bellow the enemy events. I remember from the chat that I should add something like X position of Enemy is in frame position or someting, but I dont remember all. If someone could make a Copy-Paste-able sentence, it would be perfect cause Im kinda noob and dont know where all the stuff are My enemy object is called "Enemy".

It's very difficult to help you with you just telling us the name of your enemy object. We might be able to eliminate the problem in the first place if you explain how the enemies are moving into the frame. Is it a custom movement or one of the default ones?

Ah, well the enemies are always moving towards my player.. This is how it moves:

X Position of Enemy < X("Player)+1
+ Enemy: Set X Position to X("Enemy")+2

X Position of Enemy > X("Player)-1
+ Enemy: Set X Position to X("Enemy")-2

Movement selection is static.

You could add this condition to the event - it may not make a lot of sense on the surface, but...

"Enemy" is NOT getting more than -16 pixels away from window's edge

This is under the "Position" submenu of the Enemy object - you need to negate the event for it to have the opposite effect as written, and the "-16" means that the event will only run if the enemy is within the game window or fewer than 16 pixels away from it.
