flip horizzontally by yourself

wollty

I have an actor who moves random
every 2 seconds
interpolated self.position.X to random(100,700)
interpolated self.position.Y to random(100,700)

how can I do the flip horizzontally?
when it goes right?
and when he goes to the left?

all by yourself
without using the mouse

thanks for your attention

Are you changing the image/animation when it moves?

If so try storing the last random position x and y in an attribute and if the next random x is higher than the last x it's going right (change image/animation accordingly), otherwise it's going left. And do a similar thing for y.

how can I store the last position X and the last posistion Y?
thanks (and sorry for my bad english, i used google translate)

Instead of checking it's last position, check the current position against where it's going to.

Set up two 'real' attributes on the actor called

Move To X
Move To Y

Change Attribute Move To X = random(100, 700)
Change Attribute Move To Y = random(100, 700)

Then set up 4 Rules to change the images for 4 directions (vertical included), 2 if you only want to flip horizontal

If Attribute Move To X < Self.Position.X
Change Image/animation to Left

If Attribute Move To X > Self.Position.Y
Change Image/animation to Right

Do the same for Y if you want to change image/animation to one that's facing up or down.

Then

interpolate self.position.X to Move To X
interpolate self.position.Y to Move To Y

You don't need to worry about changing the image if Move To X is the same as Self.Position.X or Move To Y is the same as Self.Position.Y unless you want to use an image where the actor is standing still, tapping his feet etc.

I put a real attribute

game.lastX

constrain
game.lastX to self.positionX

When
self.positionX> game.lastX
change attribute
self.graphics.Flip orizontally to true

When
self.positionX <game.lastX
change attribute
self.graphics.Flip orizontally to false

wollty

well
I tried both ways and they both work well

I think it's better like you said with the real attribute directly into the actor and not in the game

thank you very much

I don't really understand your example as you're not showing where you're putting the random numbers but if you've got it working how you want then I'm glad to have helped.
