On my project, I have a boss that is supposed to move around and try to kill you. I haven't added the fighting yet, but I'm wondering why when the boss is at the same Y Level as you, it starts jumping around randomly. Very strange. Project link:
https://turbowarp.org/639737429
And it might take a while to load.
Another glitch is that it lags horribly when the boss is moving against the wall sometimes. I know that it is because the collision script is confused, because the way it collides. If your velocity is positive/negative, it will collide based on that. If your Velocity is 0 when you collide, The movement script just causes lots of lag because it is trying to find out whether it is positive/negative and it is neither, so it just completely dies. I don't know how to fix this, however. Thank you, bye!

You need to make the AI not change its y-position when its y-position is within a certain range of the player's y-position. If it's moving more than 1 pixel at a time, then it's skipping back and forth over the player's y-position, trying to make it equal when it can't. I haven't seen the project, but as far as I know, that's what's causing the glitch.

Player

etc.
(The ovals are the enemy with its AI; as you can see, it's skipping back and forth because it's moving too far. Don't slow down the movement; stop it when it gets close enough.)

ok. I'll see if it works

I already have it stop moving after the distance to player becomes less than 50 in the Y movement script.

You need this:

((y position) - ((y position v) of (Player v)))

The distance uses the Pythagorean Theorem to get the total distance to the player, in a straight line. You just need the y-difference.
