This is a simple example where I used the "Pin" behavour to give the player an effect of grabbing to something.
Sudgestions and examples with other ideas for this topic are welcome!
Example contains:
-Basic description in eventsheet
-Grabing on objects with pin behavour
-Releasing the grabed object with "jump" button that makes a jump effect and "down" button to fall off the grabed object
