redownload my capx above and compare the differencies, you should see, it's obvious.

(clue : in my explanation I did say "change something" not "add something")

Challenge accepted :D

As you describe it I don't see any ways to do this. But it would help if you describe the gameplay you want to implement.

'Cause maybe you don't see the problem at the right angle (:

Even if you're just asking for a basic low level functionnality it helps to see the whole picture.

you want to do the looping thing?

I think it might be either an animation on the sprite itself, or an automatic rotation (once launched it will play until a certain angle)

For the first option it's juste sprite animation so let's go to the second one

Make an instance variable for the player object called "looping" with default false

and for events :

System: a < -80
Mouse: [invert] Left button is down
    -> Player: set looping to true
Player: is looping
    -> System: substract 80*dt from a
System: a < -275
    -> System: set a to 85
    -> Player: set looping to false

Player: [invert] is looping
    Mouse: [invert] Left button is down
        -> set a to max(a-rotationSpeed*dt,-aMax)
    Mouse: Left button is down
        -> set a to min(a+rotationSpeed*dt,aMax)

yep do that for width and height

and it's more targetWidth and targetHeight (or targetSize if they have the same Width and Height) because a scale is a ratio between the new scaled width and the original width (:

what kind of path? circular? linear? curved?

and how do you define this path?

like that whaleRip.capx

best I can do verticalMovingPlatforms.capx

few comments in the capx

Basically when you touch the screen the whale tilt up and goes higher, when you don't touch the screen he tilts and goes down.

Other than that an autoscroll based on horizontal speed of the whale.

There's nothing about friction, damping, you don't have environmental elements that influence the whale's movement (Except for the speed burst but it's just speed...) it's just all about simple orientation of speed vector. Maybe some secondary element does use physics, but the whale is definitely not physics driven.

You can emulate the same kind of movement with a simple bullet behavior.

heartHUD.capx

well I leave the details to those who handle them :D
