Slam Dunk Contest with PlayStation Move

Mark Horsley, Gameplay Engineer, NBA 2K11: It was critical for us to showcase the full range of abilities of the PlayStation Move motion controller, so we started with the Slam Dunk Contest. The dunk contest input interface was significantly revamped for PlayStation Move, allowing the ability to pull off dunks much easier than in years past. When you get your hands on this mode with the PlayStation Move, start by pulling and holding the T button to pick up a ball from the ball rack. As your player runs towards the basket, start the gestures for the dunk you wish to perform. For analog-stick-based controllers, the input is done by twirling the stick. The stick commands translated naturally to gestures using the Move controller. A counter-clockwise circle on the stick translates to moving your hand in a counter-clockwise circle, and similarly translates for other commands. By completing a gesture while running towards the basket, and then quickly completing another gesture prior to takeoff, you choose which dunk you wish to perform. To complete the dunk, simply release the T button to time the release of the ball. Props are placed on the court by pressing the Triangle button on the Move controller, just like in years past with the standard controllers.

Gameplay with PlayStation Move

For regular gameplay, we started with the single most important aspect in basketball: shooting. Our goal was for fast, responsive shooting, with no lag. All of the different types of jumps are in there: drifters, leaners, and fade-aways. Based on how your player is moving, simply flick the PlayStation Move motion controller up and you’ll spot up and shoot the appropriate jump shot. Similar controls are done for dunks and layups. Running towards the basket while holding the T button results in a dunk, as opposed to a layup if the T button isn’t pulled. Unlike the analog-stick-based controllers, you get flashy or power moves based on what is happening. Kobe running free on a breakaway? Pull up on the Move controller and witness an amazing flashy dunk. Garnett in the paint? Flick the PlayStation Move motion controller up and unleash a crushing dunk.

Here is the breakdown in more detail:

With the T button pulled, flick the PlayStation Move…

• Up = Smart Dunk
• Right = Power Dunk
• Left = Flashy Dunk
• Down = Reverse Dunk

Without pulling the T button, flick the PlayStation Move…

• Up = Smart Layup
• Right = Hop Step Layup Right
• Left = Hop Step Layup Left
• Down = Spin Layup

For Passing, we wanted to make sure the gesture was as intuitive as possible for the sophistication of the PlayStation Move motion controller. Pressing the large Move button, in conjunction with pressing the left stick in the direction of the intended receiver, will result in a quick pass. Holding both L2 and the T button while passing will throw a devastating alley-oop pass. You will find that passing is quick and accurate with this method.

Dribbling using the PlayStation Move falls into two categories: standing and moving. Holding the L2 button, flick the PlayStation Move to perform many different dribble moves to blow past a defender. If standing, you will receive a variety of Sizeup moves, based on the direction of the motion. If dribbling, here is breakdown:

While dribbling towards the basket, hold L2 and Flick the PlayStation Move…

• Up = Behind-the-back dribble move
• Right = Crossover if ball is in right hand, an In-n-Out Move if ball is in left hand
• Left = Crossover if ball is in left hand, an In-n-Out Move if ball is in right hand
• Down = Stepback

Successful defense relies on quick, decisive action, and so the PlayStation Move defensive controls were designed for quick, simple motions. Flick the PlayStation Move up for a block; flick it right or left for a steal. Player swap is an important aspect of defense, and the Move button is perfectly positioned for this. Setting a pick is assigned to the Circle button: it’s easy to access but not something that you’ll press by accident, making it perfect for picks.
