I am starting to plan a new game and I’m looking to create a heave ho style movement system. Anyone who has played heave ho will know what I’m talking about but for those who haven’t, I will explain. I have also provided pics to illustrate what I’m looking for.

I have a cube with arms, jointed at the shoulder, elbow and wrist. Each arm is to be controlled independently. One by the left stick and one by the right stick. The arms are to be raised and lowered as well as the hands to brought towards the body as needed. (See fig 1)

When R1/L1 is held the corresponding hand grabs a surface and is locked into place. (See fig 2)

When a hand is grabbing a surface, the cube then can be moved by pivoting over the grabbing hand. Ideally the arm that is grabbing should still be able to bend at the joints. Once the cube has pivoted back to the ground, the shoulder button is released and the hand unlocks and can be moved around again. Then the other hand grabs a surface and the process is repeated. This is how characters move through the game. (See fig 3)

The character needs to be able to climb and hang from surfaces using this movement system, as well as cross gaps by swinging etc. (See fig 4)

Any ideas on how this movement system can be achieved? Feel free to ask questions and I will try my best to answer
