Change the actor graphic based on movement Left or Right

Toby

Having issues with building what i figured would be a dead simple solution. I want an actor to automatically move left and right and have the graphic on the actor change to match the direction moved.

I found Tshirtbooth's video on direction, but this won't work for me for some reason. I assume it's because I'm interpolating the motion to a random position rather than accelerating.

My code looks like this:

Every 5 seconds
Interpolate (selfpositionX) to (random 50,975) Duration (random 3/5) Ease In Out

Rule
When self.motion.linearvelocity.X < 0
Change actor Image (e.g. left)

Rule
When self.motion.linearvelocity.X > 0
Change actor Image (e.g. right)

Any ideas?

Or when right button is pressed animate& Move(And then the walking right animation)

I should add: This actor is not controlled by the keyboard, its an enemy so this is a little wandering routine left and right.

Yeah you need to change your change image to an animate image in each rule.

Toby

Change image or animate image makes no difference.

Ah-ha found a simple solution:

Create a variable (integer) called eg: currentlocation inside your actor.

Timer
Every 5 seconds
Interpolate (selfpositionX) to (random 50,975) Duration (random 3/5) Ease In Out
Change attribute (self.currentlocation) to (self.position.X)

Rule
When self.position.X < self.currentlocation
Change actor Image (e.g. left)

Rule
When self.position.X > self.currentlocation
Change actor Image (e.g. right)

Works great, sometimes it helps just to talk through the logic to find a solution!

if you are doing a flip motion of a single image, why not changeAttribute self.Graphics.Flip Horizontally true/false

Rule: when
self.Position.X < self.currentlocation
changeAttribute: self.Graphic.Flip Horizontally To: true/false (depends on the initial image's being a L or R view)

same for > self.currentlocation

less resource-draining than changeImage.
but, of course, wont work if the two images are totally different!

great thinking you did on that one @Toby … pat yourself on the back!
