Yup that's right.
Sorry but i don't know how to edit my last post.
Basically i'am asking about how to make an enemy chase / seek the player in platform game.
And i want my enemy sprite capable of facing right and left (mirrored) while chasing the player.
And last thing i want to make is the chase action triggered only when that enemies is on-screen, so they won't chase the player all the time.
Just that , thx for replying
