Patrolling issue

AssortDis

Hi,

I need an actor to move back left or right when it reach the end of screen with the following rules but for some reason, it just stop when reach the end of screen without going back.

Move in direction 0 at speed 300

Rule
     If self.position.x >= game.displaysize.width, move in direction 180 at speed of 300

Rule
     If self.position.x <= game.displaysize.width, move in direction 0 at speed of 300

Thanks in advance.

Try this:

constrain self.position.X to:

(( game.Display Size.Width /2)- self.Size.Width /2) *sin( game.Time *100)+ ( game.Display Size.Width /2)

I'll need some time to figure out how exactly that formula works though ^^

(( game.Display Size.Width /2)- self.Size.Width /2) *sin( game.Time *100)+ ( game.Display Size.Width /2)

⬤ Range of movement / distance (as a radius from the centre point)
⬤ Speed
⬤ Centre point of movement

Thanks a lot, this gives a pretty great result without adding too many rules.
