Hi blackhornet, If you checked the capx file attached, you will see that I didn't used the physics behavior. It is only the 8 Directions, pin behavior and solid.
Solid is saying "don't move over a certain object", and Pin is saying " ALWAYS move relative to the parent". You can't have it both ways - something has to give. So it seems Pin trumps Solid.
Maybe you are right, the two behavior cannot affect each other.
It's not clear what you would expect to happen. Do the Blobs stop moving or do they stop the player from moving. The last won't happen as the Pin mechanism is one way. Player affects Blob, but Blob does not affect Player.
I want the Player to stop moving if one of the blob is stuck by the collision on solid elements.
