How do I make npc stop running next to a wall

So I create player sprite and enemy sprite. Both have platform behavior. Enemy fallow player when distance is smaller then 75 pix.

Problem start when enemy can't fallow you and is running into wall. Player animation change to iddle when is running into wall, enemy make error and dont change animation. Both use same events. How to fix that?

Create a variable "distance" for the enemy, then for each enemy - put into it distance to player. It works for me

GT88 You don't need "for every enemy".

Ok, it work! Thanks for help both of you!
