how do I group objects that parts are rotating as one object without pinning so when it moves it moves as one object
Assign one sprite a rotate behaviour and set other sprites angle equal to moving sprite angle. You can use conditions/instance variables to control it. http://www.upload.ee/files/3382776/teat.capx.html
