How to trigger angle of motion just once?

Hi everyone,

I want the enemies to spawn out of the screen and if they spawn to the right of the player they go to the left, and if they spawn on the left of the player, they go to the right. I don't wish they to change their direction.

To do this I made these behaviors:

As you guessed, it didn't turn very well and the enemies don't stop following the player.

Do you know how to fix this?

Thanks!

change the is on screen to on created, then you can remove the trigger once and the stop loop for they are not needed.

Many thanks LittleStain!

It worked like a charm!

Another trick is adding a "Trigger once while true" condition.

Many thanks thiago! That will help a lot too!
