Unity Echo

I played a bunch of Lone Echo and got inspired to re-create the zero-G mechanics from Lone Echo and Echo Arena. Since very few games have them. Their https://www.gdcvault.com/play/1024446... gdc talk helped a bunch.

The prototype includes:

• Tablet Physical UI
• Procedural Hand Animations
• Zero-G Physically Based movement
• Physically based interactions
• Full Upper Body IK
• Lower body physics simulation
• Moving vehicles
• Realistic Zero Gravity Movement Option (To prepare you for real zero gravity. Use with caution)

The prototype was developed and tested using a Meta Quest 2 using the touch controllers connected to a PC.

There are still some issues that I didn't have the time to figure out. Stuff like:

• Thumb finger IK

But besides that, it should function similarly to lone echo's mechanics. Of course, the prototype uses Unity's physics and we don't get access to the low-level code. So there was some trial and error to get things to feel good. I added a blockout level and some light puzzle objectives to get a feel for the mechanics, but nothing complex.

Known Issues:

You can clip through the geometry if you really try, say by rotating while grabbing at a wall.
