PlayForm: Human Dynamics

PlayForm: Human Dynamics is an experimental physics sandbox where you control Stan, a physically simulated human, across varied worlds. He can run, jump, climb, push, pull and smash through the environment, while you use tools and obstacles to create situations and test how he responds.

Stan’s movement

Stan uses active ragdoll technology. Rather than following canned animations or simplified movement rules, he continually works out how to apply muscular force to stay upright and balanced while responding to gravity, collisions, friction and impacts. His hand-tuned balancing system allows for responsive movement, and his actions vary with each situation. He may stumble comically or improvise movements in ways you do not expect.

When the object beneath Stan moves, he shifts his weight to keep his balance and may use his hands to get back up. If he is thrown into a wall, or a wall is thrown into him, he reaches toward the incoming impact to brace himself.

Open playgrounds

You can choose from a variety of large, open playgrounds to test Stan’s abilities. Slide down hills, climb mountains, leap across gaps or swim in the ocean.

Create sandbox challenges

In sandbox mode, you can design contraptions, levels and challenges with tools, hazards and building blocks. Place objects, weld them together, connect them with flexible joints and attach high-powered motors.

Physical world and sound

The world is physically simulated, including objects Stan holds. Items respond to gravity, buoyancy and friction. Collisions produce audio based on an object’s material, mass, speed and angle, while Steam Audio provides real-time sound propagation and binaural audio.
