How do I get a Pinned a Sprite to move vertically via Sine?

I've got a head that has two mouth pieces pinned to it and I want the two mouth pieces to move up and down but that's impossible because they are pinned to the head. So how can I possibly do it?

Good question - and I have no clue how to solve it

But I have a work around - you could make a mouth up and down animation instead of a single frame. I think in this example it would work nicely.

The other (stupid) idea I had was to jump trough a cycle of different origin points.

fm4fanAT, there's a way to change origins points? How?

Yes - here is a simple example

make a few Imagepoints to your objPlayer (in this case 4)

make a variable called gVariable and add every second +1

also every second set the gVariable to %3 (3 stands for the number of imagepoints -1 > so if 4 it rewrites it to 0)

Action

objSprite > setPosition to objPlayer (imagepoint = gVariable)
