How do I Make this piston work?

Im making a 2D Minecraft type game where you watch how the world interacts with itself (making my own AI type thing with the animals.) You as the observer can interact in said world, kind of like a "god" in a sense. Im trying to make a piston that can pull the blocks back in when deactivated. the grid is 50x50 and i need it to work no matter the orientation. pin behavior isn't working so far, if anyone has any advice, pls let me know. sorry for no pics, they wouldn't load.

Pics would definitely help to understand your question. You can upload them to any service like imgur and post links here.

I don't know if these will work, i do apologize if they don't, unfortunately, my access here is limited because this computer is school owned for the gaming concepts/E-Sports class, link suggested for the pictures was blocked. Again, I apologize if it doesn't work and i will try to find a way to put pictures if it doesn't.

file pics wont work, sorry you have to deal with school computers. try not using behaviours, but code.

if piston is two parts here's some code that'll probs work.

On (button press) -> (piston wood) move (X) pixels in (direction facing)

-(piston wood) on collision with (other block), (Piston wood) Pin to (other block)

On (button release), (piston wood) move (X) pixels in (direction facing) -180 degrees.

Hope this helps and you can figure out a release mechanism!
